摘要
文中针对电容型验电器失效的现象,以220kV输电线路用电容型验电器为例,分析其工作原理及影响因素;通过仿真建模计算分析了金具、导线分裂数、验电角度对验电器启动电压的影响,并根据仿真计算结果对电容型验电器进行改进,通过试验及现场应用证实了改进方法的有效性,解决了220kV输电线路验电失效的问题,可确保作业人员的人身安全。
In this paper,according to the failure of the electroscope,the working principle and influence factors of thecapacitance electroscope for 220kV transmission line are studied. The impact of the starting voltage by the fittings,separated number of sub-conductor and angle between the electroscope and the conductor are analyzed through simu-lation. By the result of the simulation,the electroscope and used it on 220kV transmission line under different condition is modified,which could solve the failure of the electroscope,and this can assure the safety of the workers.
