摘要

对配用新型液压弹簧机构的高压SF6断路器的分（合）闸过程和原理进行了分析

在假定碟簧力特性为某一均值时

对刚分（合）速度进行了实例计算

并与实测值进行了比较

结果基本一致。最后就相关问题进行了讨论。

Abstract

This paper analyzed the process and principle of opening（closing） in an SF6 HV GCB with new type hydraulic-spring mechanism.The force characteristics of the disc spring was assumed by a certain average values

and the instantaneous opening（closing） speed were calculated.It had been proved that the calculated data meet well the practically measured results.Finally

Some feasible suggest for designing of the hydraulic-spring mechanism has been given.
