数字化接地故障定位装置在10 kV配电线路故障处理中的应用

Application of Digital Grounding Fault Location Device in Fault Treatment of 10 kV Line

目前接地故障定位技术存在故障处理流程不清晰、故障查找装置体积大不方便移动、故障查找装备与电力内网数据不能贯通等问题。分析了10 kV配电线路常见故障类型,介绍了数字化接地故障定位装置的原理和处理流程。应用案例验证了能贯通电力内外网的数字化接地故障定位装置可以精确定位故障点,实现了减负增效的效果。

At present, the grounding fault location technology has some problems, such as unclear fault handling process, large and inconvenient fault finding device, and connection between fault finding device and Intranet data. This paper analyzes the common fault types of 10 kV distribution line, and introduces the principle and processing flow of digital earth fault location device. The application case verifies that the digital grounding fault location device can accurately locate the fault point and realize the effect of reducing load and increasing efficiency.
