Optimisation of the operating‐power of the circuit breaker interrupter

To reduce the operation power of the circuit breaker interrupter, here, the operation power is divided into two parts: the arc reaction force and kinetic energy of the moving parts, then the reaction force and the reactive force work calculation method are put forward. Based on the above method, the operating power of the original structure and the improved structure of the interrupter are obtained, and the comparison of the results shows that the improved structure can reduce the operating power.
