摘要
煤矿井下供电系统因其本身的结构特点以及现有设备的局限性,在实际运用中经常出现越级跳闸,引起井下停风、停电等一系列问题。为了有效解决煤矿井下越级跳闸问题,通过建立一套网络继电保护方法,改变了传统的保护方式。该方法经过现场试验证明,不需要额外增加设备或者线缆,维护也简单,可以有效解决煤矿井下越级跳闸问题。
Because of the structure features and limitation of the equipment of power system at underground mine, the power system often occurs the jumping trip, which causes the issues of ventilation stop and electricity power off. In order to effectively solves the jumping trip issue at underground mine, sets up one network relay protection method, which changes the traditional protection. The field test demonstrates that this method do not need to add extra equipment or cable, easy to maintain and can effectively solve the jumping trip issue at underground mine.
