摘要
煤矿掘进工作面越来越长,供电安全存在隐患。报告简单分析掘进工作面存在的问题,提出多相位短路保护供电的解决方案,并对方案设计的原理特点进行了详细介绍。通过实践证明,多相位短路保护供电是一种安全有效的远距离供电保护方式。
As heading face of coal mine is longer and longer, hidden dangers exist in the power supply safety. Report simple analysis the existing problems in the heading face, puts forward the solution of multiple phase short circuit protection, and introduce characteristics and principle of design in detail. Proved by practice, multiple phase short circuit protection is a safe and effective way to protect remote power supply.
