| 摘 要： | 漏电保护是煤矿井下三大重要保护之一,对人身安全和设备的稳定运行起到至关重要的作用。在中性点不接地系统中,单相漏地占绝大多数,尽管它不破坏系统的对称性,但非漏电相对地电压会增加为原来的几倍,若不及时处理,极易发展成两相短路,造成更大危害。本文针对矿井低压漏电保护进行研究。

| Abstract: | Leakage protect is one of the three important protects in mine,it plays crucial role in the personnel safety and equipments' steady run.In the isolated neutral system,single phase is predominating.Although it doesn't damage system symmetry,non-leakage phase-to-ground voltage fold increases which if don't deal with in time,it will develop into two-phase short circuit and cause greater damage.Low-voltage leakage protect in mine is researched. |
