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

What is a circuit breaker?

Circuit breaker is usually used to distribute electric energy and protect the power line. When the circuit load exceeds the limit, it can automatically cut off the circuit. Therefore, it can be regarded as a current switching device that can turn on, carry and turn off the circuit under certain conditions. Generally speaking, circuit breakers are divided into two types: high voltage circuit breakers and low voltage circuit breakers. Among them, the low-voltage circuit breaker is widely used, and the difference between high voltage and low voltage is 3KV.

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

What is a high voltage circuit breaker?

The main function of high-voltage circuit breaker in use is control and protection. It can not only cut off or close the no-load current or load current in high-voltage circuit, but also protect the circuit device through relay in case of circuit system failure, because it has very perfect arc extinguishing structure and current breaking capacity. Through this protection, the expansion of circuit problems can be prevented, and the faulty part can be removed from the whole circuit system, while the non faulty part can still operate normally.

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