摘要
煤矿井下供电系统有着复杂性、不确定性,由于结构特殊以及现有设备的局限性,在实际井下应用中会出现以下情况:开关的不分闸、误操作、越级跳闸,导致高开不能及时切断电源,引起井下停风、停动力,造成损失。应该充分利用好高开的综合保护装置,使其发挥正常的作用,就会极大地降低事故的发生。
The underground power supply system has the complexity and uncertainty, universality, due to the limitation of the special structure and the existing equipment in the actual application, there will be the following:switch off, misoperation, override trip, which resulted the high voltage switch cannot promptly cut off the power supply, and then cause to the wind and the special power stopping, resulting in the loss . We should make full use of high comprehensive protection device, make it play a normal role, which will greatly reduce the accident.
