针对目前我国煤矿高压电网普遍采用6kV或10kV电缆直接供电状况,在阐述了矿井高压电网3种不同的接地方式的漏电机理的基础上,详细分析了电网中不同接地方式在发生漏电故障时对漏电保护选线的影响。
In view of the fact that the power supply conditions of 6kV or 10kV cables are commonly used in high voltage power grids of our country nowadays, the leakage mechanism of three different earthing modes of mine high voltage power grid is expounded. The leakage characteristics of different earthing modes in power grid are analyzed in detail. Protect the effect of route selection.
