The Capacitive Current Testing Device of Systems With Ungrounded Neutrals

准确测量中性点电容电流是实现配网电路理想补偿的前提,对降低配网事故具有重要意义。传统方法测量电容电流时,测试人员通过绝缘工器具接触带电的中性点,有一定的危险性。针对这一问题,研制了一种中性点不接地系统电容电流测试装置。该装置体积小、精度高,采用无线遥控方式完成接线、测试、拆线等操作,不仅能方便准确地测量中性点电容电流,还有效解决了测试过程中的高电压隔离问题,显著提高了工作效率和作业安全性。

Accurate measurement of neutral capacitance current is the premise of achieving ideal compensation,and it＇s quite important for reducing the accident of distribution network.When the capacitance current is measured by the traditional method,the tester has to contact charged part by insulating tool,and it has certain danger.In order to solve this problem,a capacitive current testing device for neutral point ungrounded system is developed.The device is small in volume and high in precision.It can complete connection,test and disassembly operation by wireless remote control.It can not only measure neutral point capacitance current conveniently and accurately,but also solve the high voltage isolation question in the test process.The work efficiency and operational safety have been significantly improved.
