交联聚乙烯电缆现场交流耐压试验

Field AC Withstand Voltage Test on XLPE Cable

针对直流耐压试验方法的局限性,提出了应用串联谐振方式来进行交联聚乙烯电缆交流耐压试验,介绍了串联谐振的试验原理和电气参数的计算方法。结合现场试验经验,讨论了试验电抗器的电感量取值、试验场地的影响、试验有功损耗等试验相关问题。

Aiming at the limitations of DC withstand voltage test, the paper proposes the method of series resonant to carry out AC withstand voltage test on XPLE cable, and introduces the principle and calculation of the test. Combining with the field experiments, it discusses the calculation of reactor impedances, the impact of test field and the active power loss.
