在线式矿井高压电缆接地故障定位装置的研制应用

The Application of the Online High-Voltage Cable Grounding Fault Locator Device in Coal Mine

针对矿井高压电缆单相接地故障难以排查的问题,介绍一种基于相模和零模电流行波多频段相模解析的在线测距装置,讲述其原理、结构及应用效果。

In mine high-voltage cable single-phase grounding fault is difficult to troubleshoot,so this paper introduces an online distance measuring device based on phase and zero model electric wave multiband phase analysis.The paper mainly describes its principle,structure and application effect.
