摘要
针对接触网检修作业中出现的验电器无法准确验电的现象,以GSY-Ⅱ型27.5kV电容型验电器为例,首先分析了其工作原理,然后通过仿真计算比较接触网中不同位置验电器的电容电流值和最小起动电流值,分析验电位置对验电器灵敏度的影响,最后通过现场试验验证了仿真结果,对现场检修作业具有指导作用,可有效保障检修人员的人身安全。
According to the inaccurate checking of the electroscope during the catenary maintenance operation,the GSY-Ⅱ 27.5 kV capacitive electroscope is taken as an example.Firstly,the working principle is analyzed,and then the capacitance current value and the minimum starting current value of the electroscope in catenary different positions are analyzed through simulation,and the influence of the electroscope position on the sensitivity of the electroscope is analyzed.Finally,the simulation result is verified by the field test,which has a guiding function for the on-site maintenance work,and can effectively protect the personal safety of the maintenance personnel.
