摘要
针对目前电缆外护层带电检测方法存在的问题,提出利用直流电流分流原理的高压电力电缆外护层带电检测新方法,分析电缆外加直流检测的原理和方法,从电缆外护层绝缘故障查找、电缆外护层接地系统接线正确性验证两方面介绍该方法的应用情况和应用效果,说明该方法简单实用。
Aiming at the cable protecting layer electrified detection methods existing problems, this paper puts forward high voltage power cable support layer of charged detection method by DC current shunt principle, analyzyes the principles and methods of detecting DC outsitecable. From the outside of the cable support insulation fault finding, cable support layer grounding system wiring correctness verifies the application and application effect of the method, shows that the method is simple and practical.
