交联电缆直流电压及泄漏电流试验的探讨

Discussion of the XLPE Cable for DC Voltage and Leakage Current

探讨了交联聚乙烯绝缘电力电缆在敷设安装试验及使用前预防性试验中的方法,分析了交联聚乙烯绝缘电缆出厂试验标准和电气设备交接试验标准的区别,介绍了直流电压试验和泄漏电流试验的测量目的、方法及对测试结果的评定,讨论了影响正确读取泄漏电流值的因素。

This paper discusses the issue of XLPE insulated power cable in the preventive tests and installation process, analyzes the difference between XLPE cable factory test standards and electrical equipment handover test standards, introduces the objectives, methods and assessment in DC vohage test and leakage current test and discus-ses the factors in how to read leakage current value correctly.
