配用弹簧液压机构的SF_6断路器刚分(合)速度的计算与分析

Calculation and Analysis for Instantaneous Opening(Closing) Speed in SF_6 HV GCB with Hydraulic-spring Mechanism

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。

This paper analyzed the process and principle of opening （closing） in an SF6 HV GCB with new type hydraullc-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 hydraullc-spring mechanism has been given.
