After 2 years, the decision on whether to test the vacuum degree once a year or twice a year will be made based on the operation status of sf6 circuit breaker operating mechanism. At present, since the instruments for testing the vacuum degree without disassembly on site are not yet perfect, power frequency withstand voltage is still a more effective method to test the vacuum degree of sf6 circuit breaker spring mechanism.
