摘要:

通过对合闸传动过程的分析,计算出断路器的合闸负载功率及合闸功率,进而设定刚合速度值,利用能量守恒法计算出操动机构合闸弹簧的相关参数。根据计算出的合闸弹簧进行断路器合闸速度测试,实测速度值与理论值一致。

关键词: 合闸功率, 负载动率, 刚合速度, 能量守恒, 合闸弹簧

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
