摘要
本文分析了高压直流输电用直流滤波电容器试验中的几个关键试验,通过对局部放电试验的分析,认为直流滤波电容器的局部放电性能应该以放电脉冲数来衡量,这与试验研究的结果是一致的;本文还提出了直流滤波电容器的热稳定性试验应该考虑的问题和交流热稳定性试验的试验电压确定方法;通过对极性反转试验和直流滤波电容器的耐久性试验进行分析,对极性反转试验方法提出了建设性的意见,建议对全膜电容器在直流电压下的老化问题进行深入研究。
In this paper, several key tests of DC filter capacitors for high voltage direct current （HVDC） transmission is analyzed. It is thought through analysis of partial discharge that the partial discharge performance of DC filter capacitor is judged by the number of the discharge pulse and this is in agreement with test result; moreover, the issues which shall be considered in the thermal stabil-ity test of DC filter capacitor and determination method of test voltage in the AC thermal stability test are proposed ; the constructive comments on reversal test method of polarity is proposed by way of a-nalysis of reversal test of polarity and endurance test of DC filter capacitor. It is suggested to perform deep study of aging of full film capacitor under DC voltage.
