Abstract

Abstract:

Based on the analysis of the closing transmission,the load power and closing power of the circuit breaker are calculated.Then the closing spring parameters are calculated with the energy conservation method by setting the speed of just close.The closing speed of the circuit breaker is tested according to the parameters of the closing spring.The measured value of closing speed is consistent with the theory.

Key words: closing power, load power, speed of just close, energy conservation, closing spring
