4-13. AUTOMATION TO RECEIVE THE INTERVALS OF THE CONSTANT STRUMA AT A NOMINAL STRUCTURE UP TO 24 V
To get rid of the overstroke lantsyugiv, to live with low-pressure dzherelny struma vpruguyu up to 24 V, to stagnate unipolar automatics (Fig. 4-40) and the nominal continuous strum from 2 to 50 AU. The stench is discharged of the same size and I may fall asleep at the strum of the showcase for an hour with all strumas, great near-cordon, which is located between the nominal strum and 120-130% of the nominal.
Small. 4-40. Automatic machine for picking up a stitched strum for 50 a, 24 st.
With a stream, which is 200% of the nominal, the showcase for an hour in the middle of the week is between 25 - 80 s with heating from a cold mill and not less than 5 s for a program with a nominal stream. The size of the road is 10.00 a with a nominal rate of up to 10 a and 1 500 a for a viconan on a large nominal rate. Warranties term of service 10000 inclusive.
A characteristic feature of the design is the visibility of a vivid split, but in some cases it is worthwhile, so it is possible to trim the machine in a closed mill, without affecting the appearance of a superstroke.
When the handle is "on", the ruchomy contact 1 should be pressed to the unstable 2 behind the auxiliary pin 8, which is a spring 9. When the block 3 is pressed, the spring is 4. When the thermo-metal plate is reversed, turn, teeth 5 and 6 go out of the connection, if the handle does not shrink when it is turned on, then it is turned on, so that when the spring is injected, all 4 of the handle does not go out of the way.
4-14. SEMI-STROKE AUTOMATIC AB-45-1 / 6000
Automatic machine AB-45-1 / 6000 for sprung 750, strum 6,000 and permanent strum - unipolar, with an electromagnet drive, with a switch-on switch and maximum detection of mittєvoi diy with a regulated setting of 6,000-12,000 amps. Win buv razrobleniya for zashist tough installations post-strum, the head rank of metallurgical. The principle kinematic circuit of the machine is approximately the same as in universal machines; Protective hour of the first time is reduced, for which the maximum connection with the inductive shunt is stuck (Fig. 4-41).
Small. 4-41. Maximum breakout with an inductive shunt for the AB-45-1 / 6000 submachine gun for 6000 I, 750 in a post-strum.
A part of the magnetic flow, opened by the strum, must pass through the magnetic conductor 1, pass through the shunt 2, and will take the third turn. With great speed, the struma grows through the shunt, the shunt grows more and more through the inflow of the medium sleeve 4, so that the anchors are pulled up to the accelerated weight.
When viprobivanny (L. 4-9], unaffected by the great swiftness of the build-up of a strum (25-10 + 6 a / s), the power hour of the start is 10-15 msec, the strum is not automatically interconnected and after reaching 200 kA, the automaton is triggered by force. .In analogous sinks, the VAB-2 submachine gun has interconnected the strum up to 42 kA. Forward
Bagato hto know about the school course in physics, how the strum will change and last. Just as about the stagnation of a changeable strum, the world can be told about it (all by the way of electricity to live from a changeable strum), then practically nothing is known about it. Allegedly hedge of a post-struma, meaning є і who lives, і apparently, such a measure may be needed. Determination of the survival of the post-strum and at whom the view of the apparatus for the destruction of the family of the strum is discernible in the stratum.
Zhoden from the type of electric strum is not "pretty", but not the best - to go for the show of singing establishments: the change is ideal for the generation, the transmission of electricity to the great industry, that is, to establish a special dream energy, tribute processing centers, electric power stations, etc.
Shafa rozpodilu post-operative strum electrical station
A clearer idea of the change and post-strum is given a read of the announcement about the factory, from which the automatic vim of the post-strum are stuck. Zminny strum promiscuous frequency(50 Hz) change of direct in the electric lance 50 times per second and style and time to "cross" through the zero value. Tsey "transition" meaning the strum through zero when the electric arc is extinguished. In the lancers of the post-strum, the meanings are permanently - like and directly in the strum, constantly in the hour. It’s a fact that it’s quickened to extinguish the arc of a post-strum and that in the form of special design solutions.
Accepted graphs of normal and transitional modes when enabled: a) changeable stream; b) post-struma
One of these solutions is the victorian of the permanent magnet (3). The rocking of the arc in a magnetic field є one of the ways of extinguishing in devices up to 1 kV that can be found in modular automatic Vimicachs. On the electric arc, like a conductor along the way, pouring in a magnetic field, and that is drawn into the arc-extinguishing chamber, and it is left to quench.

Polarity of demand
Another one, mabut, key view between automatic controllers of a changeable and permanent strum є in the remaining manifestation of polarity.
Wiring diagrams for single-pole and double-pole automatic vimikach post_strum
If you seize a single-phase boundary of a variable strum behind the aid of a two-pole automatic vimikach (with two captured poles), then there is no difference in either of the poles of the switch a phase abnormal guide. When automatic switches are connected to the netting of the post-strum, it is necessary to adjust the correct polarity. When a single-pole vimikach is connected, the supply voltage is supplied to the terminal "1", and when the two-pole is connected, to the terminals "1" and "4".
Why is it so important? Wonder video... The author of the video is to carry out tests from a 10-amp wimicach:
- The inclusion of the vimikach to the edge of the polarity - nothing is seen.
- Vimikach of upheavals at the edge of the ringing polarity; the parameters of the hemisphere are U = 376, I = 7.5 A.
- In terms of polarity, the strum is set to 40 A, which is 4 times the nominal value. Thermal zajist, like tse y maє buti, having opened the lancer, he will be stolen in a few seconds.
- The last and the lowest test was carried out with the same 4-fold changes in the strum and the vocal polarity. The result is not having to worry about yourself - mittuve zaymannya.
In such a rank, automatic vimikachi post_stіy strumu - tse attachment to the seizure, how to become stagnant for the objects of alternative energy, systems of automation and control of industrial processes and іn. Special records of the given characteristics Z, L, K allow the seizure of highly technological possession of industrial enterprises.
Modular automatic vimikachi post-struma, or automatical, vikoristovuyutsya in electrorecords and electrical installations, telecomunication shafs, automation panels. What is called modular? All on the right is that the stench is released in standard compact cases and single-pole modules, which can be folded into single-pole, double-pole or tripolar attachments. It is an obvious standard, the width of one such pole is 17.5 mm.
Automatic vimikach of a post-struma struma is seen from an individual team, short confusion or її re-entangled automatically. The construction of the annex includes a number of main elements:
Successively automatic controllers take advantage of two detectors (attachments):
From the great vyshekazanny viplivє, so vimikachі postіy struma zdatnі virіshuvati takі zavdannya:
Significantly, the automatic post-strum machine develops as an analogue of the alternate strum in the first place, which is very polar. It is necessary to wait until the hour of the connection.
Main reloads
Automatic vimikachi nabuli a wide expansion of the production of low perevag:
In addition, automatic functions for robots with a permanent strum are capable of operating in the range of 6 to 125 A, so that they can be used for any kind of possession or electric power.
Important characteristics
Automatic vimics for robots with a permanent strum may have the following main characteristics:
Yak mi vzhe said vishche, for the hour-strum characteristic, the letter of the meaning will be stuck:
In such a rank, in order to ensure the protection of the netting, when choosing an automatic vimikach, it is necessary to select its characteristics according to the characteristics of the possession of that cables.
Why do you want to make a purchase from our store
At the ATLANT SNAB store, you can choose an automatic post-production strum with any characteristics that will trick you. Ale, tse is not the only reason, through the yaku you can prydbati vimikach with us:
To buy vimikachi post-struma at a time, make a purchase on the site, or just call our contact number. Having turned up to us, you want b times, you, melodiously, will become our last customer!
All electrical fences have a great number of attachments, the main function of which is the line and possession of struma that short confusion. In the middle of them, a wide widening of an automaton was filled with a fancy, so that a vicon was not deprived of a zapper, but a coma of lantsyug. In such a rank, automatic vimikachi will not be able to turn on and off certain files, to seize them from the struma by way of switching them on, so they will be snatched up in case of emergency situations.
Types of electric automat_v
Automatic vimics are widely used in power supply systems, without prejudice to the overhaul of electric lances and fences, by-turn attachments and electric controls. To the main staff of the lancer at the necessary moment, the way to turn on the supply of the electric strum. The automatic transmission of the machine will be returned to the operator during short interruptions, as well as for an hour when the wires are loaded through the re-entanglement in the hedgehog.
The automaton can acquire practicality in the lances of the permanent and changeable strum, and the universesal constructions of the building are successful for the manifestation in the hem of a kind of electric strum. As far as the design is concerned, the stench is divided into three types, which are the basis for the other types of automatic vimics:
- Turned automatics. Vikoristovytsya in industrial virobnistvі, de strumi in lantsyugah can sagati a few thousand amperes.
- Automatic machines in a die-cast case. They vary in a wide working range, from 16 to 1000 A.
- Modular automatics The very stench itself is widespread in apartments and private booths. The name is tied with a standard width, which becomes a multiplicity of 17.5 mm, lying down from a number of poles. So, in one block it is possible to vicoristovuvati at once a kilka vimikachiv.
All of them are automatically adjusted up to the indicators of the nominal strum and some of the larger annexes are installed in the framing 220 or 380V.
Automatic vimics can be strummed and not strummed. The first one has an automatic machine є vimikachem, at which hour the connection is set to a superficially small value, by stretching out a short stumble, one cannot reach the maximum.
Automata are classified for a number of poles and can be one-, two-, three-polarized. The stench is to be possessed by the maximum, square, minimum, and zero points of napruga. Great importance is the speed of communication, if the attachments can be normal, high-speed and selective. For children it is allowed to do so. technical characteristics... Deyakі models have good contacts, and the guides connect to them in a new way.
Isnu podіl on різні tipi for the design of the pump and the pump installed in the machine. These elements play an important role and are used as magnetic and heat. In the first case, the rozmikach is referred to shvidkodіyuchih, and it will be unaffected by short stutters. The hour of spratsovannya becomes 0.005 to 3-4 seconds. The robot of the heat detector will run more and more, so it will be important to get overwhelmed. The basis of the element is a bimetal plate, which heats up with increasing pressure. The period of spratsovuvannya is between 3-4 seconds to a few hilin.
In addition, automatic connections are made for types of connections. Kozhen type A, B, Z, D, K, Z. For example, type A vikoristovuyutsya when rozmikannі lantsyugіv, which may mean more wiring, good fortune napivprovidnikov attachments. Between spratsovuvannya become 2-3 nominal strumi. Type B stays in the systems of illumination of the zagalny sign and the threshold of 3-5 nominal struma. Reports on the skin type of the machine can be taken from the tables.
Typical rozcheplyuvach_v automatic vimikach_v
Effortlessly rozcheplyuvachi, as vikoristovyutsya in automatic vimikachi, you can intelligently go to two groups. Before the first group, enter the annex, scho seize electric lancersі create a critical situation, if it is overstretched. As a result given development Emergency support for the additional breakdown of the main working contacts.
Another group of roscheplyuvachіv is represented by prefabricated annexes, but do not enter until basic kit automatic You can get in touch with:
- Nezalezhnі rozchіplyuvachі, zdatnі remotely switch on automatically pіd hour, the appropriate signal from an additional lancer.
- Razch_pylyuvach minimal springs. Viconu turned on the machine at times when the springs are lower than the allowable ones.
- Rozch_pylyuvach zero spill. Yogo contact is rozmikayutsya at the time of the significant fall of the napruga.
Teplovy rozch_plyuvach
Zrazok heat razch_pylyuvacha performances on a baby, vikonanii at the viglyadі bіmetalіchnoi plate. In the process of heating, it starts to change, the shape and the pouring into the mechanism are changed. To make a plate, two metal lines use a mechanical path. Material of the skin line is a low coefficient of temperature expansion. Z'єdnannya vikonutsya by the method of soldering, zvaryuvannya or riveting. Vigin of the plate to pretend to be a rakhunok of the little girl dozhini before the hour of loading. Warmth razch_plyuvachі will prevent the transfer of the re-entangling struma and can be adjusted to the tasks in the mode of communication.
The head endurance of the heat detector is the strength to vibrations, the visibility of the parts, how to rub, and the ability of the robot in the obstructed view. The stench comes from the simplicity of design and low quality. As a shortage of time, it means the long-term energy supply, sensitivity to temperature changes, the ability to save money when heated with third-party djerels.
They also took away the electromagnetism of the electromagnetism, which can be used for the mittvuch, on a wider scale. Structurally, the stench of vikonany at the viglyad is salty with a core, which is poured onto the mechanism, which is very different. If the winding of the solenoid is against the overstroke, it is necessary to bring up the magnetic field to the opening of the magnetic field, moving the core, and at once the support of the rotary spring is applied.
The adjustment of the electromagnetical control is carried out on the basis of a short delay, the value being set to 2-20 ln. Have your own bank, the value of ln = 200 A. Pohibka adjusting can become 20% in the direction of the given value. To that, the settings of the reference for power automatics are indicated in amperes, which is a multiple of the nominal strum. The modular automatic parameters may indicate the given characteristics, which are indicated (3-5), C (5-10) and D (10-50), the digital values correspond to the boundary nominal string ln, at any time when the contacts are diverging.
Electromagnetic rozchіplyuvach
The main advantages of electromagnetics are the durability to vibrations, blows and mechanical injections, as well as the simplicity of the design, which will allow repair and maintenance of the annex. Until a short time, you can bring a mittve spratsyuvannya, without eye-catching at the hour, and wind up the magnetic field for the hour of the robot.
The show for the hour is of great importance, the marks for the її rakhunok take care of the selectivity. For the obviousness of the selectivity of the vibration, the opening automaton detects the appearance of a short confusion, but the singing hour is just skipped. With a sweep of a long time-lapse, I am guilty of overtaking the spratsyuvati lower-standing zhisny pristіy, which does not include the whole object, but deprives me of the dilenk.
Delivering often thermal and electromagnetical rozchіplyuvachі zastosovovyutsya spіlno, by way of the last day of both elements. Such a call was called a combined thermomagnetic sensor.
Forwarding providnikovy
Up to more folding annexes should be located on the conductors' offices. Before the skin warehouse, there is a control unit, a control unit, a transformer for a changeable flow or a magnetic pressure for a permanent flow, as well as a high-power electromagnet, which shows the function of an independent driver. Behind the additional block of keruvannya, a program is established, it is designated by a clerk, for the authorization of what kind of head contacts are to be detected.
In the process of setting up, the following events are displayed:
- The nominal strum is regulated to the machine
- Set up a showcase for an hour at the zones of re-entanglement and short-circuiting.
- The short delay setting starts.
- Nalashtuvannya zahisnyh peremykach_v on the basis of single-phase inclusion.
- Adjusting the changeover, which will take an hour to catch up, if, with a short delay, the selectivity mode changes to the mitten mode.
Electronic razch_plyuvach
The design of an electronic device for an analogous device. Win is also stored with electromagnet, vimiruvalny attachments and control unit. The value of the robotic struma that hour of the showcase will come up often, without the guarantee of a quick start-up struma.
The advantages of the cich are adjusted to the versatility of the adjustment and the power of the vibor, the robot established by programs with high accuracy, the presence of indicators of the correctness of the reasons for the explanation, the logical selective connection with the vimikachs who have been rooting out the bottom of the machine.
Until a short time, you can bring a high price, a crispness to the block of keruvannya and sensitivity to the flow of electro-magnetic fields.
On the very cob of the winners of the electricians, the engineers began to think about the safety of electric fences and attachments from the struma navantazhen. Nasledok ts'go bulo is designed richly small annexes, as they turn out to be above and beyond that. Some of the outlets have become electric automatics.
The whole set is called automatic through those that are equipped with the function of connecting the living room to automatic mode, in the case of short trips, overwhelming. Zvichny zapozhniki will be replaced by new ones, and automatically, if the reasons for the accident are ascertained, they can be turned on again.
Such a fix is required for any electrical circuit. Deceitful machine to seize wake up, for example, in case of emergency situations:
- Pozezh.
- Hit the people with a string.
- Wiring faults.
See that constructive features
It is necessary to know the information about other types automatic vimikach_v, for an hour before the bannya correctly vibrate the vidpov_dniy prist_y. Є Classification of electrical automatics for a number of parameters.
Vimikayucha building
The power of the strum of a short flicker, when the machine is open the lance, by itself, turn on the edge and attach it, like the bullets are connected to the edge. For the price of power, the following are automatically generated:
- Automatic machines for 4500 amperes are stuck to prevent the inadequacies of the power lines of the old equipment.
- At 6000 amperes, it’s possible to get lost for emergency situations when we’re confused in the hedgehogs in new buildings.
- For 10,000 amperes it will be stuck in the industry for the seizure of electrical installations. A stream of this magnitude can be asserted at the perfect proximity to the station.
Spratsyuvannya automatic vimikach vinnikє when confused, how to supervise the vimiknennya singing size of the strum.
The automatic machine is used to secure the electrical wiring from the isolation of the great strum.
Number of poles
Qia power to tell us about the most wires, as you can connect to the machine for securing the user. In case of an emergency, the pressure on the poles is switched on.
Features of automatic devices with one pole
Such electrical automatics are the most simple for their design, and serve for the seizure of all kinds of hedgehogs. Before such an automatic vimikach, you can switch two darts: input and output.
To the managers of such annexes, the protection of the electrical wiring is rewired and the short circuit of the wires. The neutral wire is connected to the zero bus, bypassing the machine. Grounding must be connected okremo.
Electric automatics with one pole are not initial, since when the phase is switched on, the phase is opened, and the zero wire, which is earlier, will be lost to the current supply. I will not get overwhelmed 100%.
The power of automatic devices from two poles
In case of an emergency, if there is a need for more electrical fences, it will automatically operate from two poles. The stench of vikoristovyutsya yak entry. In emergency situations, or with a short interruption, all electrical wiring is switched on in one hour. The price is given to the possibility of working with the robot for repair and maintenance, as well as carrying out the work with the connection of the possession, some of them are guaranteed to be safe.
Bipolar electric automatics, if the need for an outbuilding is required for an outbuilding, which can be used for 220 volts.
The automatic machine from two poles is connected to the annex behind the auxiliary wires. Of these, two come from the bottom of the living, and the other two come from the bottom.
Tripolar electric automatics
In the electrical framing, there are three phases, 3-pole automatics are frozen. The grounding is unprotected, and the phase guides are connected from the poles.
The tripolar automaton serves as an entrance attachment for any triphasic survivors. Most of this version of the automatic machine will be stopped by the industrial minds for the livelihood of electric motors.
You can connect 6 guides to the vending machine, three of them - phases of the electrical framing, and three can be connected to the vending machine, which is secured by the operator.
Vikoristannya chotiripolyusny machine
In order to secure a triphasic line with the help of a chotiriprovid system of guides (for example, an electric motor, switched on for the "zirki" circuit), to block a 4-pole automatic wimak. Winning the role of an introductory attachment to the chotyriprovidnoy festoon.
Є Possibility of connecting up to an annex of eight guides. On one side - three phases and zero, on the other side - output of three phases with zero.
Hour-struma characteristic
If there is an attachment, you can live with electricity, that is an electric line that works in a normal mode, it will be able to go through the strum. Price for an electric machine. Ale, at once, for some reason, they had been forced to make up for the nominal value, they had to see the automatic transmission of the automatic machine, and the lance was opened.
The parameter of the whole spratsovuvannya is called the hour-string characteristic of the electric machine. Won the fallen hour of the automatic machine spratsyuvannya and spіvvіdnoshennya mіzh by the real force of the strum, scho pass through the automaton, that nominal values of the strum.
The importance of the central characterization of the pole is in ensuring that the least number of households spratsovan from one side, and to get the best strum, from the other side.
In the energy industry, there are situations, if for a short time the struma is not tied to an emergency, and the zahist is not guilty of the lawsuit. Also seen with electric machines.
Hour-strum characteristics will start, after an hour they will start, and parameters have caused the strum to fail. Chim more navantazhennya tim shvidshe spratsyuє automatic machine.
Electric automatics for "V" markers
Automatic display categories "B", completed in 5 - 20 seconds. At the same value of the strum, set from 3 to 5 the nominal value of the strum 0.02 s. Such automatics will be used to clean up side-by-side outbuildings, as well as efforts to wiring apartments and buildings.
Authority of automatics from markup "S"
Electric automatics of the category can be activated in 1 - 10 s hour, at 5 - 10 times the strummed one - 0.02 s. These are the most popular areas for business, apartments and other areas.
Significance of Markuvannya "D "automatically
With such a class, you can automatize vikoristovuyutsya at promislovosti and vikonanii viglyadi 3-pole and 4-pole vikonan. Їх zasosovuyut in order to clean up tough electric motors and three-phase attachments. The hour of їkhny spratsyuvannya become up to 10 seconds, with a whole stream of spratsyuvannya it can be changed to a nominal value of 14 times. This allows for the necessary effect of vicarious schemes for the recovery of other schemes.
Electric motors due to the significant strain are most often connected through the electric automatics with the characteristic "D", because high triggering strum.
Nominalny strum
Є 12 options for automating, which are based on the characteristics of the nominal robotic stream, from 1 to 63 amperes. The whole parameter is the initial value of the automaton when the boundary value of the strum is reached.
The automatic machine for the price of power vibrates from the transverse recession of the conductors of the wires, which is allowed by the strum.
Principle of electric automatics
Snazzy mode
With a special robotic machine, the importance of information is controlled, the strum goes through the wire to the upper terminal. Give the strum to a non-harsh contact, through a new one to a hard contact, and a tart dart to a solenoid coil. Pislya ny on the dart of the strum on the bimetal plate of the rotor. From the strum to pass on the lower terminal and distance to the mounting.
Navantage mode
Tsei mode is vynikє for re-assignment of the nominal machine gun. The bimetal plate is heated with a great strum, and that rozmika lantsyug. It takes an hour for the plate to lie down through the sign of the struma to pass through.
Automatic wimicach є analogue add-on. When it is adjusted, it is foldable. Strum spratsovuvannya rozch_plyuvacha will be installed at the plant with a special regulating gwent. The automatic machine knows how to operate the plate. The temperature of the bimetal plate should be deposited as a form of the metal plate.
Razchіpylyuvach dіє not all at once, giving the chance to turn the nominal value. If the strum does not go down, then it’s spratsovu razchіpylyuvach. The rewiring can be done through the strapped annexes on the line or by connecting to one or more annexes.
Short mumble mode
In the whole regime, the strum is growing very fast. The magnetic field in the cobweb is the core, which can be brought into play, that enables the contacts of the liveness, we ourselves know that the lancet is unavailable and the landlord is in the middle of the fire.
Electromagnetic rozchіpylyuvach dіє mittevo, nіzh іdrіznyayєtsya as a heat rozchіpluvach. When the contacts are open in the working stake, an electric arc appears, the value of which lies in the struma in the lance. Vaughn has sprinkled contacts. The arcing chamber is broken, and it is stored from parallel plates. At niy arc zgasaє that znikaє. Gazi, scho win, enter into a special opening.
