Safe Use Of Sf6 Circuit Breaker Operating Mechanism And Prevention Of Common Problems

Therefore, the following points should be noted during use.
Clarify the difference in the manufacturing standards of the pressure gauges used and do not confuse them. The pressure gauge reading used by the "former" is the gauge pressure gauge reading specified in my country, that is: gauge pressure = absolute pressure - atmospheric pressure. The pressure gauge reading used by the "latter" is equal to the absolute pressure number. For the same pressure of gas, it is 1 more atmospheric pressure than the "former".
The sf6 circuit breaker operating mechanism currently in operation (taking the rated pressure of 0.5MPa as an example), if measured using the pressure gauge specified in my country, the gauge pressure reading of the sf6 circuit breaker spring mechanism produced by the former is 0.5MPa; the gauge pressure reading of the SF6 circuit breaker produced by the latter is only 0.402MPa.
