摘要
总结了各种交直流耐压试验手段的原理、优缺点及与工频试验的等效性,认为串联谐振试验是取代工频试验的最佳选择。介绍了电缆介损与局部放电诊断技术的发展现状以及与超低频、振荡波和串联谐振三种典型交流电压试验的融合情况。通过对三种交流诊断性试验等效性的比较分析,提出了相关建议。
This paper firstly summarizes AC/DC voltage＇withstand test methods in terms of their principles, advanta- ges and disadvantages, and equivalences with power-frequency voltage test, and concludes that the series resonance test is the best alternate to power-frequency test. Then it introduces the development status of dissipation loss and par- tial discharge diagnosis technologies of XLPE Cable and their integrations into the three typical AC voltage tests, in- eluding Very Low Frequency （VLF） , Oscillating Wave （OW） and Series Resonance （SR） test system. By compa- ring and analyzing the equivalences of three AC diagnosis tests, some relevant suggestions are finally proposed.
