Abstract

High voltage circuit breaker is a very important tool in the power supply system. The use of circuit breaker will affect the safety and stability of power system operation. SF6 gas is an important insulation and arc extinguishing medium in high voltage circuit breaker. SF6 can eliminate the hidden danger of loader, and the power supply of electrical system shall be stable. The process of identifying trust is very important.

With the development of high voltage and high capacity power system, it is very important to ensure the safe operation of high voltage circuit breaker. High voltage circuit breaker is an important electrical equipment in electrical system, and plays an important role in controlling and protecting power supply. It is easy to introduce new hidden dangers and reduce the reliability of devices. Therefore, it is very important to check the position of high voltage circuit to check the real-time performance of the circuit.

It is proved that the state monitoring of the circuit breaker effectively ensures the safe and stable operation of the whole power grid system, and also plays an important role in ensuring the reliable operation of the high voltage circuit breaker, reducing the huge human resources and material resources waste caused by planned maintenance, and has great application value.

According to the structure and operation characteristics of SF6, separate circuit breakers and converters and piezoelectric devices can be provided. It is designed for the displacement of dynamic contacts and mechanical vibration signals. According to the specific operation parameters of such circuit breakers, SF6 can be modified. Combined with the normal operating range of SF6 circuit breaker parameters, the influence of environment on the moisture content of SF6 gas is analyzed in detail.

Key words: SF6 circuit breaker; Condition monitoring; Fault diagnosis; Condition maintenance
