Differential automatic machine: connection diagram

Differential automatic machine - the same module is not possessed, like one hour at a time the functionality of dekilkoh outbuildings. Or rather, the ability of automatic machines, which protect the mesh from the overshoot, that short zamikannya (viniknennya overstrike), that attachment of the zahisnogo inclusion (PZV) - possessed, as if it were protecting people, and also all those who can stick with the shattered part of the drone. Tobto this attachment reacts to the wind of electricity. To the very same, the differential automaton is universal and protects your mesh.

Main functions

1. Zakhist of the electric line in the coil of the struma on the surface of the earth.
2. Zakhist vіd revantazhen or short chirps at the lancers. In other words, the Danish attachment is actually an automatic switch and ELV, yakі dnani in a single building.

Differential automatic machine or ELV, high swidkod zavdyaki, secures the maximum protection of people in the injection of an electric stream, at the same time dotik to non-current-carrying and stream-carrying parts. In the first breath, the stench can swell under tension when the insulation is damaged or broken.

In addition, this automatic machine, similar to a sizable automatic wimming, effectively protects the electric lines when superstrings are faulted in them - overshooting along the stream and short flickering in the electric lines.

Ways to zahist

The defender of people at the sight of differential automatic machines is like this. Under normal operation, the work of the electrical appliances of the lance is regularly balanced by the neutral of the output and the input electric jet. At the time of the manifestation of retail, the meaning of which can become unsafe for the life of a person, there is an osichka, so that the electric lansyug is fired, which is protected.

Zakhist of the electric lancet in the changeover and struma of a short hum is organized for the auxiliary module of the zakhistu (automatic switch), which is connected to the differential machine. As a result, when the strum is passed, if you change the nominal value of the strum of the differential attachment itself, the machine will instantly start, and the faulty lance will appear without electrical voltage.

Main warehouses

The middle of the differential automaton is connected to the last connection of the nodes.

1. Nodes of automatic vimics:

• bimetal plate (thermal rozchіpluvach), as a protection from the vantage;
• magnetic rozchipluvach, scho guards against overshort flickering.

2. Module of differential control (electronic switch):

• electronic podsiluvach, possessing an electromagnet cat;
• the transformer, which is made up of a toroidal core, protects the electric current from a coil and protects people from an electric shock.

How to choose a differential machine

This electrical attachment is selected from the rozrachunk and the total struma coil. Next, choose such a facility, if you can have the maximum commutation building, for end buildings - at a level of 3000 A, for group ones - 6000 A.

From the numerical quantity of electronic differential automatic machines, it is necessary to choose from the protection of the zero conductor. Shards of shaving can provoke the waste of energy by automatic machines, so that they can be robbed with unproductive ones.

On scho turn respect for the hour of choice

As you look at the types of differential automatic machines, once again pay attention to those who are given the possession of miraculous solutions for the safety of safe electrical wiring.

Vzagali, types of differential attachments are significantly different from each other, like a vartost, and for technical characteristics. Therefore, choosing a differential automaton (diagram below), it is necessary to orient ourselves towards the stream of indicators and only then on the variance.

Principle dії

These extensions, as a rule, are made from dielectric materials (as it is practical not to conduct a stream). The working part of the differential control is formed from the slats of the skid, which secures the sound of the connection, the mechanism that viconizes the independent opening. A coil of electric stream was placed on the back part of the yard, and farther away, the inclusion of life by way of the vimikach was thrown off.

Krym tsgogo in the design includes rozchіpluvachі: electromagnet and thermal. Remaining spratsovuє in case of apparent vanity in the line, the first one at the time of closing turns on the line.

The facts of the turns are taken care of by the transformer, which fixes in conductors, as a way to serve food to groups, which is protected, change the voltage. The opening of the machine is activated when the coil is detected - the presence at the secondary winding of the stream.

Scheme of connecting a differential machine

The installation of the differential attachment is simple: it is fastened to the mounting DIN rail of the base shield behind an additional buckle, as it is attached to the rear part of the body. In the general order, it is necessary to have a ground connection, because without it it is not allowed to operate a differential machine. After the installation, a re-verification of the obladnannya under the interests is required. The "Test" button is pressed, as a result, the vimicach is guilty of mittevo vmknutsya.

It is important to choose the correct number of amperes and to increase the amount of amperage, in order to avoid the overvoltage, for which it is necessary to turn it on.

The connection of a differential automaton is possible for the following schemes:

1. Differential attachment is connected before the introduction. A similar scheme is to secure the protection of the current group of the electric stake.
2. Okremy automatic machine is installed on the skin lancet of life. Vin protects all the elements connected to it.

For the first drop, there is only one short one. If the machine is turned on, the merezha will start to flicker. In another way, there is an inclusion of a less okremo group, which is richer practical than that better. But at the same time, the first scheme for connecting a differential automaton takes a little time, and the smut is cheaper.

Pokrokov's instruction

Come in later

The differential attachment is protected to be installed on a group of sockets, which are planned to be connected to personal computers, shards can provoke a pardon, which will lead to the calculation of the calculation technique.

In addition, it is not allowed to connect the line of other automatic devices with the zero line, the spikes along these lines flow absolutely different streams, which will also lead to the inclusion of a differential automatic device.
