煤矿井下远方与就地漏电试验的比较

Remote Leakage Test Comparing with On-the-spot Leakage Test Underground in Coalmines

对煤矿井下中性点不接地供电系统远方与就地漏电试验的方法进行了比较,认为远方漏电试验可以验证就地漏电试验,是检验漏电保护可靠性的重要措施;远方漏电试验的地点应尽量靠近检漏保护装置。

By comparing remote leakage test with on-the-spot leakage test in underground power supply system without the neutral line earthing, this article considers that the remote test can verify the on-the-spot one and is an important leakage protection measure. The place of the remote test should approach the leakage protection device.
