| 摘 要： | 漏电是煤矿井下低压电网的主要故障形式之一。针对漏电保护有各种原理,它们各有优缺点,如直流检测式的全面性、旁路接地式的安全性、方向保护式的选择性等。在实际应用中使它们有机地结合起来将获得更好的效果。基于这一想法设计了旁直零漏电保护系统,该系统具有全面、安全、可靠及有选择性的保护性能。

| Abstract: | Creepage is one of major malfunctions for low voltage power system in coal mines.There are many different methods to deal with creepage.And each of them has flaws and merits.For example DC examination type has comprehensive functions,grounded bypass type is safer,directive protection type is selective.If they can be combined in real life it will have better effect.Based on this idea article will focus on PZL creepage protection system,which is comprehensive,safe,reliable and with selective protection. |
