供电可靠性要求越来越高，对低压配电线路的供电情况一直缺乏监测，不能随时掌握台变的运行情况，如果台变发生跳闸事故，只能通过用户打电话通知电力部门，经常出现停电后不能得到即时地处理，给用户带来工作、生活的不便，长时间的停电也会带来很大的经济损失。分析发生故障停电后报修不及时的原因和对策，研制了一套低压停电故障报警监测系统，在台变跳闸停电后能够通知电力抢修部门，使故障停电报修的时间尽可能的缩短，有效的减少了故障停电时间，提高了供电可靠性，同时有效地提高了供电企业的优质服务水平。%There is higher demand for supply reliability. There is not enough monitoring of the supply of low-voltage distribution lines, and so we can not keep up operation of bench transformer. If the bench transformer occurs tripping accident, we can notify the power sector only through user's call. If the blackouts are often and can not be immediately treated, it will bring inconveniences to the work and living of the user, and also will bring great economic losses. This paper analyzed the causes and countermeasures for not timely repair to failure blackout, developed a set of low-voltage power failure alarm monitoring system which can send the tripping blackout to electrical repair department, reduce the repair time and effectively reduce the fault outage time, improve the reliability of power supply, at the same time improve the level of quality service of power supply enterprise.
