摘要
针对现有直流充电型振荡波局部放电检测系统试验电压较低以及被试电缆承受直流电压的缺点,研制一种基于变频谐振的振荡波电缆局部放电检测系统,试验电压达1000kV甚至更高,并且满足局部放电试验要求。
According to the defects of low voltage of DC charging type oscillation partial discharge detection system and tested cables withstand DC voltage, oscillation cable partial discharge detection system based on resonant frequency is devel- oped. The testing voltage has higher voltage up to lO00kV and partial discharge test requirements are met.
