[0002] Circuit breakers are switching devices that can close, carry and interrupt current under normal circuit conditions, and can close, carry and interrupt current under abnormal circuit conditions within a specified time. As the core component of switchgear, the quality of vacuum circuit breakers has always been a focus of attention. According to the statistical analysis of accident types in the operation of high-voltage vacuum circuit breakers in the national power system, insulation accidents account for a large proportion, so the insulation structure is a major point in the development of vacuum circuit breakers.
