地下电缆故障精准定位方法

Accurate Positioning Method for Underground Cable Faults

针对地下电力电缆故障查找的难题,基于传统的电缆故障定位方法,结合实践提出了一种通用的三步定位法,通过确定故障类型、故障预定位、故障精准定位三步定位流程可直接精确定位至电缆故障点,实践证明该方法可有效提高电缆检修排障的效率,具有较强的通用性和实用性。

In allusion to the difficulty of detecing faults in underground power cables,a universal three-step positioning method is proposed based on traditional cable fault positioning methods and combined with practice.By determining the fault type,pre-positioning and accurately positioning faults,the three-step positioning process is enough for directly and accurately locating the cable fault points.Practice proves that this method is available to effectively improve the efficiency of cable maintenance and troubleshooting with strong universality and practicality.
