Despite the apparent reliability, all electrical equipment, without exception, can operate only in a narrow range of priority values of current and voltage. As soon as any of these values falls below the norm, the device stops functioning. If the normal values are exceeded, there is a risk of equipment burning, since the device is unable to turn the resulting amount of energy into work.
This forced scientists to look for ways to protect equipment from fluctuations in current and voltage in the network. At first, numerous fuses appeared that normalize the current for the operation of equipment by reducing/ increasing resistance when changing the parameters of the incoming current. Later, automatic machines were designed, which became an important milestone in the history of the development of electricity.
The principle of operation of the machine
Electric automata are a special device that provides automatic network disconnection when the operation of a current source is destabilized. Under normal conditions, this device is part of a circuit; under extreme conditions, set by installers, it opens the contact of the current source with its consumers.
The characteristics of electric automata vary greatly, as these devices are needed in power grids with very different parameters. An automatic machine that provides disconnection of a direct current network has a slightly different design than an automatic machine for alternating current. The designs for single-phase and three-phase lines also differ.
At the same time, all types of electrical automata designed to work with alternating current operate according to a single scheme – according to the principle of potential difference. The wires from the source fit to one set of terminals, and the wires to the recipient fit to another set of terminals. A special device analyzes the difference in current strength in the network before and after the machine. In case of critical situations (short circuit, etc.), the current strength changes by a significant amount, which prompts the device to open the circuit.
The machines work according to this type, despite the differences in design. Modern devices of this type can be performed in the following ways:
• modular DIN-rail automaton;
• automatic machine in the fuse box;
• three-pole automatic;
• automatic machine in a cast case.
At the same time, automatic machines of the first proposed type are most often installed in electrical panels (in old buildings there are units of the second); for installation at home, the last option considered is most often used.
The need for verification
It should be borne in mind that devices of this type need serious inspection, which must be carried out by competent specialists. It is necessary to check the correct connection of the unit, otherwise it will not be able to detect potential differences and power loss in one direction. It is extremely important that the machine itself is serviceable and functioning properly. To do this, it is set at the factory to turn off at a given range of current deviations from the norm.
Automatic machines are a much better means of protecting equipment from voltage surges and short circuits, but do not forget about standard fuses.
