In the modern society with advanced science and technology, people's life is closely linked with the use of electricity. At work, people use computers, mobile phones; Back home, television, lighting, air conditioning, and so on, are also inseparable from electricity. However, how much do we know about the related knowledge of electricity consumption? What is a high voltage circuit breaker? How does the circuit switch work? In fact, people almost know nothing about these, the following, for you to introduce some relevant knowledge about circuit breakers.

What is a circuit breaker?

The circuit breaker is usually used to distribute electrical energy and protect the power supply line. When the load of the circuit exceeds the limit, it can automatically cut the circuit. Therefore, it can be regarded as a current switching device that can close, carry and open circuits under certain conditions. Generally speaking, circuit breakers are divided into two types: high voltage circuit breakers and low voltage circuit breakers. Among them, the use of low-voltage circuit breaker is wider, the difference between high voltage and low voltage is 3kV as the dividing line.

In addition, if the circuit breaker needs to operate normally, it must meet the following conditions: rated voltage, rated current, current range of overload protection, and rated short-circuit breaking current. Only when the above conditions are met, electrical accidents can be effectively avoided.

What is a high voltage circuit breaker?

High voltage circuit breaker in the use of the main role is control and protection, it can cut off or closed in the high voltage circuit in the no-load current or load current, and in the circuit system failure, it can also pass the relay protection circuit device, because it has a very perfect arc extinguishing structure and the ability to break the current. After this protection, it can prevent the expansion of the circuit problem, and remove the faulty part from the whole circuit system, while the part without fault can still operate normally.

In terms of structure, the high voltage circuit can be divided into the diversion part, the arc extinguishing part, the insulation part and the operation part. From the point of view of the arc extinguishing medium, can be divided into oil circuit breaker, air circuit breaker, vacuum circuit breaker, magnetic blow circuit breaker and so on. From the nature of operation, it can be divided into electric mechanism, pneumatic mechanism, hydraulic mechanism, spring energy storage mechanism and manual mechanism.
