摘要
针对煤矿供电系统中的越级跳闸问题,基于电压波动、电气干扰及开关性能的差异性特点的发生率远大于因短路过流产生的概率,因此文中分别从技术现状、设备管理等多角度出发,给出了一项可解决越级跳闸的有效措施。
Aiming at the override trip in mine power supply system, the author presents the effective measurements from aspects of technology situation and equipment management ,which show that the occurrence rate of override trip due to voltage fluctuation, electrical interference and switch performance is much greater that of due to short-circuit overcurrent.
