摘要
对于绝缘等效电容较大的高压电气设备的耐压试验,采用0.1 Hz超低频耐压技术与工频耐压和直流耐压相比具有明显优势,但其试验技术标准和方法还须完善,对其研究有重要意义。
For the voltage endurance test of high voltage electric equipments with larger equivalent insulant capacitance,adopting O. 1 Hz ultra-low frequency voltage withstand technology, as compared with power frequency or dc voltage ensurance has obvious advantages,but the testing technology standards and the method still need to be perfect.
