GW10-10H2带温度补偿隔离开关的研制

Development of GW10-10H2 Isolation Switch with Temperature Compensation

对原有隔离开关压力弹簧受热变软导制刀闸烧损的原因进行了分析,增设了温度补偿装置,取消了多圈压力弹簧,改进了开关绝缘,能够抑制接触电阻发热,延长绝缘子的使用寿命。

Analyses the cause for the burn-out of blade gate resulting from the softening of the pres-sure spring in the original isolation swith,and points out that the addition of a temperature compen-sating device and the elimination of a few coils of pressure spring improve the insulation of the switch,suppress the heating of contact resistance,and prolong the service life of insulators.
