If we consider the load breaker in more detail, we can make an important conclusion that it is just an ordinary disconnector that is equipped with the simplest arcing chamber.
As statistics show, load switches began to be used approximately sixty ago in an electrical installation from 3 to 10 kV when using an expensive switch is generally uneconomical.
In those days, this unit was made in the form of the simplest mechanism for separation and high-quality fuse, which is designed for high loads. This combination was intended to turn off and on the idle currents, as well as turn on the load currents, as a result, the fuse served an important role in protecting the electrical installation from overload current and sudden short circuit. At the moment, load switches are used quite successfully in most electrical installations, as well as as a generator switch, in the capacitor bank circuit.
Load breakers also began to find application in foreign countries, while the process of arc extinction itself is carried out in very different ways. For several years, interest in this device in the territory of our country has significantly increased. This popularity is associated with the fact that for several years there have been active transformations in the electrical network, and this has led to changes. There is a selection of both a higher and a weaker voltage, and the load switches are the most profitable in order to solve the problem of saving and reliable power supply to consumers.
