摘要

文中提出了一种断路器用弹簧操动机构分闸时间调整方法，该方法可以在不改变断路器操作电压和运动速度的工况下，实现断路器分闸时间的调整，并通过仿真优化和实际样机试验测试，验证了调节分闸时间的有效性，为后续断路器弹簧操动机构的设计、运维检修以及变电站保护时间调整等工作提供优化参考，具有一定的指导意义。

Abstract

In this paper

the adjustment method of opening time of spring operating mechanism for high voltage circuit breaker is proposed. The method can achieve the opening time adjustment of circuit breaker without changing the operating voltage and moving speed of the circuit breaker. The effectiveness of the opening time adjustment is verified through the simulation optimization and test verification of the actual prototype

which provides optimization reference for the subsequent design

operation and maintenance of the spring operating mechanism for the circuit breaker

protection time adjustment of the substation and has certain guiding significance.
