Automatic electrical rating tables. Selection of automatic vimics. Thermal design of a number of automatic machines installed in a row

In the past, for the protection of the electrical wiring, that electrical control in such abnormal modes of operation as a re-wiring, or for a short flicker, electrical plugs were stuck, as a rule, from ceramics. The design of these outbuildings is simple.

Not a lot of tsikh outbuildings are those that, when the burner burns out, the fusible inserts for the new one are not taken care of. Nadal, the cork could not be saved at the right moment, which often caused a bug to burn.

Kіntsev machines, Mile's car, Moore's car is named as a sign of recognition of his work. At that hour, the Mili machine shows its output through the production mill and enters, exits the Moore machine, there are no more foundations on the production mill. The transition function will accept the in-line mill and the input podia and turn a new set of output pods and the offensive stan. Therefore, it can be considered as a function, as it shows the ordering of the sequence of inputs in the sequence of inputs, or it indicates the sequence of inputs.

Kіntsevy cars - іdealnі calculus models for a small amount of memory that does not improve memory. Tsya mathematical model of the machine can reach the final number of stations and transitions between them. Yogo main zastosuvannya - analysis of mathematical problems. Kіntsevy cars are also vikoristovuyutsya for purposes, kіm zagalnyh calculus, for example, for the recognition of the splendid mov.

At this hour, automatic vimikachi (AB) came to replace the old traffic jams, which may be more successful and more reliable in operation, equal to the traffic jams. Structurally, AB is a module with two input/output contacts and a switch button (single-pole automatic machine).

The working mechanism of the automatic vimikacha is located in a closed plastic case. At the rear part of the machine, there is a special stamp, the zipper can be fixed on the DIN rail when connected to the electrical panel.

Let's look at the analogy with the lift. The elevator is a mechanism, which does not remember all the previous requests for service, but flowing on top, directly ruining that selection of unsatisfied drinks for services. To that be-yakoy mitі hour of the lifting of the lift is meant by offensive mathematical terms.

Powers: the last set of stations for drinking in the past history of customers. Entrance: the end of the collection of entrance data, fallow from a large number of surfaces, on the elevator you can take access. Weekend: the end of the collection of holidays, fallow due to the need, or lowering the elevator according to the needs of customers. Kіntsev's machine is formally designated as a 5-tuple, such and such.

vibir automatic vimics є vіdpovіdalnym zavdannyam, to which it is necessary to put seriously. In the minds of guilt emergency situations Correctly vibrating the automaton є I guarantee the zakhist not only your possession, but your life.

Automatic vimikach - tse switching device assignments for automatic micing electric lansyug at the moment of viniknennya short chimes and shifting.
On the diagrams, they are indicated by the letters AB and QF (European standard).

From the above mathematical interpretation, we can say that the machine of the end will avenge the end of the number of stations. The leather mill accepts the last number of inputs, and the leather mill has the rules, how to describe the machine for the input, the functions of the conversion of the mills are presented. At the same hour, I can bring in the entrance to change, I will add it. For the skin entry symbol, there is one transition from the skin state. In addition, whether there is a set of 5 tuples accepted by terminal non-deterministic automata, it is also accepted by deterministic terminal automata.

Criteria for the selection of automatic vimics

The main indicators for yaks are used when choice of machinesє:

  • number of poles;
  • Rated voltage;
  • maximum working strum;
  • including buildings (strum short hum).

one #. Number of poles

The number of poles of the machine is determined by the middle of the phases of the mesh. For installation in single-phase mesh vikoristovuyut unipolar or bipolar. For three-phase mesh zastosovuyt three- and chotiripoleusnі (merezhі іz system of grounding neutral TN-S). At the per-butov sectors, sound the vicorist one-or two-pole automatics.

When examining machines from the end of the camp, it is important to consider the mother on the spot, that the mechanical process of using automatic machines, to calculate the number of outputs and changes of the mills, is not substantiated and not detailed; the natomist vin is respected by the “black screen”, as shown below.

Їх can be easily revealed behind the help of the diagrams of the stanіv, as shown below. The diagram will become an illustration of the robot of the machine. Become represented by nodes of graphs, transitions for arrows and arrows, and the entrances and exits are indicated by symbols. Ruhi, not connected with the changes of the camps, marked by arrows on the sides of the neighboring knots.

2#. Rated voltage

The rated voltage of the machine is the same voltage, for which the machine itself is repaid. Independently from the place of installation, the voltage of the machine is due to equal or great rated voltage merezhі:

3#. Max working strum

Maximum working strum. The choice of automatic machines according to the maximum working strum is determined by the fact that the rated strum of the machine (the rated strum of the sprayer) is greater or more equal to the maximum working (rozrachunk) strum, which can pass through the distance of the lansy for a long time, it can be protected, it can be re-protected:

Number arrows are called autopilots. There are several types of end automatic machines, which can be subdivided into three main categories. Acceptor: either accept input signals, or do not recognize: or recognize input, or do not convert: generate output data from a given input. The programs of end automatic machines are covered by various topics. The stench can be used with a finite number of lines, an infinite number of lines, different types of trees in hardware schemes, de-input, and become bit vectors of a fixed size.

To find out about the maximum working strum for a small house (for example, for an apartment), you need to know the total pressure. For whom it is possible to tighten all the accessories, they will be connected through a given automatic machine (refrigerator, TV set, sv-pich too). The size of the struma from the omitted tension can be known in two ways: by the method of setting or by the formula.

The simplest automatic machine that wins for calculation is the end automatic machine. Vіn can count only more primitive functions; that won't be an adequate calculation model. In addition, the absence of a cash machine zagalnyuvat zagalnyuvati zavazha yogo vladі.

A butt is pointed lower, which illustrates the difference between a kіtsev automatic machine and a Turing machine. Leather bit at the car, but maybe less at two camps. Otzhe, іsnuіє kіltseva kіlkіst mozhlivih stanіv. If you want leather in a car, you can only have it in two different countries, in a computer there is an inexhaustible number of interactions. It is important to model the robot of the computer at the borders of the boundary of the terminal machine. Prote vischi, neskіchennі and pouzhnіshi automatons could beat the task.

For a measure of 220 with a voltage of 1 kW, the strum becomes 5 A. For a measure with a voltage of 380 V, the value of the strum for 1 kW of tension becomes 3 A. For the help of this option, you can know the strum through the tension. For example, the total power at the apartment was 4.6 kW, the strum at this cost was approximately 23 A. For a more accurate value, the strum can be accelerated using the following formula:

Tyuring's machine can be seen as a kіntsevy automatic machine or a control unit, equipped with an inexhaustible collection. Yogo "memory" is made up of an inexhaustible number of single arrays of middle ones. The Turing machine is a day-to-day abstract model of a modern computer simplification that has been developed for the purpose of providing an accurate mathematical assignment of an algorithm to a mechanical procedure.

Although the automaton is called end, so the yogo model is formed from the end number of stations and functions from the end rows of introduction and view, unstopped automata mayut "accessory" - either a stack, or a line, you can move it to the right, or to the left, and you can be satisfied, at the same time hanging up to the car.

For butovy electric appliances.

4 #. Vimikayucha building

Vimikayucha building. The choice of the machine according to the nominal strum is turned on before the strum is any machine building the turn on more struma short flicker at the point of installation of the device: some kind of automatic switch-on at rated voltage.

The Turing machine is formally a multiple, de. That is why the main reason between the Turing machine and the double-sided end automata lies in the fact that the Turing machine is able to change the symbols on its page and imitate the computer and save it. It can be said that the Turing machine can model all calculations, so that they can be repaid today for the help of modern computers.

Pokrokov's procedure helps to sound the parameters. More designers can get good notice about those who are so automatic and how to make wine; what do you need to update, axis short appointment. An automatic switch is automatically marked by an electric switch, it is suitable for the zahistu of an electric lancer in the light of time, for crying overwhelm or a short chime. Vіn reveals injustice and interrupts the strum.

Rozrahunok strumov short zamkannya necessary for the correct choice of that vіdbudovi zahisnoy equipment. A short-circuited strum vinikaє when connecting the streak-conducting parts of the phases between each other or from the grounded body of the electrical receiver in circuits with a dead-earthed neutral і zero dart. The value of A may be assigned to the formula

The introduction of the right vimikacha at an early stage of the design process can lead to a more advanced design, reduce redesign, reduce the cost of distribution and increase the value of the final product. Ale choose the best automatic mic for your program - this is a rich process. The main functional parameters are the voltage, the strum and the number of poles are only an ear. To improve your choice, you need to insure mechanical environmental factors, food regulation and security, fencing for rozmіrom and vartystyu and richly other.

de Uf - phase voltage merezhi, V;

ZP- phase-zero loop opir, Ohm,

R - active opir one dart of a lanceug short chime, Om;

X - inductive support, which is protected behind the pet inductive support, which is 0.6 Ohm / km;

Let's take a look at the key parameters of vimicach. To achieve the function of an automatic vimikacha, there are a number of technological options, skins with some other characteristics. Table 1 has five points; stalely according to your exact numbers, for your program, you can use a sprat type. Automatic wiping different technologies, demonstrate work characteristics, which are subtly vіznyayutsya, in the minds of overwhelm. Small 1 shows qi options.

The horizontal line shows multiple values ​​of the uninterrupted vimikach strum; vertically all showing, how much time is needed to turn on the automatic vibration at a given stream. Widths of curves indicate type tolerances. For additional information, it is recommended to go back to the archway of the data.

Z t - Revision of the phase winding of the transformer on the side lower voltage, Ohm,

de uh, IH - nominal voltage and stream of the transformer;

UK% - Transformer short circuit voltage, % of nominal value.

Values uh, lH і Ubefore% for a high-voltage transformer, be directed at branch 5.

Table 1: Technology of automatic wimicach.


1: Characteristics of the characteristics of the technology of automatic vimicach. If you think of the real world, they are in the minds of minds, for which they would take away the specifics, next to stop the coefficients of lowering the var. For example, automatic vibrations with non-compensated heat-moving elements can be used to cool down due to the temperature of the necessary medium. If the automatic switch-on of the switch at the building or the hot room in such a boiler room, strum, necessary for turning on the switch when switching over, will be changed; zvorotna diya zastosovuєtsya for low temperatures.

The choice of an electric device is charged for yoga functional recognition, for the kind of strain and struma, -> about the magnitude of the strain.

Mother's trail current trend, which is based on the fact that, when choosing between zabebniks and automatic vimikachs, the rest is hoped for by virtue of their greater arrogance, the best zahistu in out-of-phase modes, versatility only.




Figure 2: Typical temperature reduction table. Similarly, the work on more high or more low frequencies, lower specified, you may also need to change the specifications. From one side, the vortex strum and the use of air at the highest frequency lead to greater heating in the components of the thermal switch, despite the decrease in the nominal strum of the vimikach.

Zagalo be-yakі nezvychaynі mind robots can help you change the parameters of the arch of data or special provisions of the design, as if the automatic vimikach is guilty of vikonuvati, like it was cleared up. As an addendum to quiet, as already discussed, such minds can include corrosion, moisture, mechanical shock and vibration, height, and it is possible to change the installation position. The specialists of automatic vimikachiv will ensure the reduction of tariffs and benefits from the exploitation, as they will help you at the top of the business.

The choice of devices for the voltage depends on the voltage rating of the nominal voltage, assigned in the passport of the device, of the same kind (change, permanent) rated voltage of life. When choosing a strum device, you should check that the nominal strum is responsible for no less than a working strum of the installation.

Selection of automatic vimics

In times of doubt, consult the experts at the factory. Automatic switches can be used for various configurations and installations for different installations on other boards, racks and panels, right up to highly specialized installations for high-voltage electrical systems.

Oskіlki avtomatichnі vimikaі vykonuyut funktsіu, pov'yazanu z sekpekoyu, є nіshіnі standards, scho see raznimi reguliruyuchimi organs. Acts of the key ones are shown in Table 2. In addition, a lot of programs, aerospace, automotive and military programs, may have their own power before testing such qualifications.

Automatic vimikachi vibirayutsya us ahead of the nominal values ​​of the voltage and struma. Then the settings of the thermal and electromagnetic switches are changed.

Teplovy rozchipluvach the automatic machine protects the electrical installation from the treacherous strum. Strum settings thermal splitter take equal to 15-20% more than the working strum:

de 1 R - Robotic strum of electrical installation, A.

Electromagnetic rozchipluvach the machine protects the electrical installation from short flashes. Strum settings electromagnetic blower vynachaetsya z such mirkuvan: the machine is not guilty of spratsovuvat vіd starting jet dviguna electrical installation Istart. dv., and strum spratsovuvannya electromagnetic rozchipluvach IEMP to be selected as a multiple of the spration of the thermal expansion valve:

de Before \u003d 4.5-10 - coefficient of multiplicity of the struma of the electromagnetic healer.

Vibranium automatic vimikach is revered for sensibility and for the inclusion of buildings. Automation nominal strum up to 100

de IO.K.Z.- Strum of single-phase short zamikannya.

The sensitivity of the machine, which can only be thermal expansion, is due to the following:
