带电更换三相高压计量保险管辅助操作工具研发

Research and Development of Auxiliary Operation Tools for Live Replacement of Three-phase High Voltage Metering Fuse

在10kV高压计量保险管被熔断时,通常采取停电处理的方法,但是存在追补电量时间跨度大、计量故障效率低、无法快速恢复供电而影响客户正常生产等问题。本文针对上述问题,提出研发一种辅助操作工具,达到同时带电更换三相高压计量保险管的目的。本文详细讲述了计量保险管故障具体问题及一种不需要停电处理的方案,以提供带电作业更换保险管参考依据。

When 10kV high-voltage metering fuse is blown,it is usually treated by power failure,but there are some problems such as long time span of replenishing electricity,low metering failure efficiency,inability to quickly restore power supply,and so on,which affect the normal production of customers.In view of the above problems,this paper proposes to develop an auxiliary operation tool to achieve the purpose of simultaneously replacing three phase high-voltage metering fuse with live line.The paper describes in detail the specific problems of metering fuse failure and a treatment scheme without power failure,so as to provide reference for replacing fuse with live line operation.
