一种新型融冰接地隔离开关研究与应用

Research on a New Type of Ice Melting and Grounding Disconnector

针对220 kV输电线路融冰前需检修人员高空搭接融冰电缆头的弊端,提出并研制了一种220 kV融冰接地隔离开关。融冰实践证明该设备操作简便,可快速打通融冰通道,完全消除了检修人员高空作业的安全风险,满足大电流融冰要求。

Aiming at the disadvantages that maintenance personnel need to lap the ice-melting cable head at high altitude before ice-melting of 220 kV transmission lines, a new type of disconnector with both ice-melting and grounding functions is proposed and developed in this paper. Through the practical test of ice-melting, it is proved that the equipment is easy to operate, which can quickly open the ice melting channel, completely eliminates the safety risk for maintenance personnel working high above the ground, meets the requirements of high current ice melting.
