电容式电压互感器现场不拆头高压试验

High-voltage test of capacitor voltage transformer

通过改进电容式电压互感器西林电桥传统反接线的高压试验方法,用新反接线方法不必拆除一次引线同样可以获得正接线方法所能得到的准确数据,不仅缩短了整个试验时间,也避免了检修人员两次在强电场环境下登高作业。

The traditional high-voltage test which is to reverse the wiring of Schering Bridge of capacitor voltage transformer is improved to get the accurate statistic which can be achieved by positive connection.The new method dose not need to remove the lead cuts down the time the test spends and prevents the maintenance staff from twice wording aloft in the strong electric field.
