Analysis of Frequent Suppression of 500 kV Circuit Breakers

Hydraulic mechanism is widely used in high-voltage circuit breakers because of its many advantages. Frequent pressure of circuit breakers is a common fault in hydraulic mechanism circuit breakers. This paper analyzes the influence of temperature on the pressure of a 500 kV circuit breaker, the causes of the failure, and puts forward the corresponding solutions. At the same time, it briefly analyzes several other possible reasons for the frequent pressure of circuit breakers.
