| 摘 要： | 对220 kV电容式电压互感器上节电容单元的介损及电容测量,一直以来采用的是西林电桥正接法10 kV测量方法,这是一种普遍使用的试验方法.但这种测量方法需要将200kV电压互感器上节一次接线拆除,现场拆除引线很不方便.本方法是采用不拆除220 kV电容式电压互感器一次接线,使用去干扰的介损测量反接法,从而避免了繁重的拆...

| Abstract: | 10 kV normal wiring of Xilin bridge is often used in the measurement of upper capacitance dielectric loss and capacitance of 220 kV capacitance voltage transformer.It is a common measurement method.But the method needs disconnecting the high-voltage line which is inconvenience.Then a new method is proposed.This way applies anti-interference reverse measurement method of dielectric loss which avoid heavy work to disconnecting the high-voltage line and improve work efficiency. |
