What Are The Criteria For Selecting The Model And Specifications Of Sf6 Circuit Breaker Operating Mechanism?

1 sf6 circuit breaker operating mechanism Rated voltage should meet the requirements of the load circuit;

2 sf6 circuit breaker spring mechanism Rated current should be greater than the circuit current;

3 The rated breaking current of the circuit breaker should be greater than the maximum short-circuit current of the circuit;

4 The dynamic stability current of the circuit breaker should be greater than the peak current of the maximum short-circuit current of the circuit;

5 The thermal stability current (I.S) of the circuit breaker should be greater than the short-circuit current action time (I.S) of the circuit breaker;

6 The operating mechanism of the circuit breaker should meet the requirements of the circuit use.
