摘要
在中性点不接地的煤矿供电系统中,发生单相接地故障时,将产生较大的接地电容电流,如不加以限制将对矿井的供电安全和人身安全造成较大的危险。本文主要分析自动跟踪补偿成套装置的原理。
In the ungrounded neutral mine power supply system, there would generate great capacitive current in the case of single--phase ground fault, which would pose great danger on the power supply security and workers personal safety. The paper mainly analyzes the principle of automatic tracing compensation complex.
