Description
技术领域technical field
本发明涉及电力设备运行监测及通信技术,特别是涉及一种低压故障在线监测系统。The invention relates to power equipment operation monitoring and communication technology, in particular to a low-voltage fault on-line monitoring system.
背景技术Background technique
配电网运行中经常发生用户380V侧开关跳闸导致的停电。由于用户侧负荷特性千差万别,而且10kV配电站低压侧一般不安装监测仪表。因此当低压出线发生故障跳闸后,往往不能及时判断故障原因是由于开关本体故障还是线路故障。目前为了便于及时抢修往往需要多个班组到达现场,同时还要携带备用开关,工作量大,响应速度慢。During the operation of the distribution network, power outages caused by the tripping of the 380V side switch of the user often occur. Since the load characteristics of the user side vary greatly, and the low-voltage side of the 10kV distribution station generally does not install monitoring instruments. Therefore, when the low-voltage outgoing line fails and trips, it is often impossible to judge in time whether the cause of the failure is due to a switch body failure or a line failure. At present, in order to facilitate timely repairs, multiple teams are often required to arrive at the scene, and at the same time, spare switches must be carried. The workload is heavy and the response speed is slow.
此类事件的频繁发生极大地增加了电网运行维护人员的工作压力,而低压配电系统中一旦发生开关跳闸,由于缺乏监测控制手段,往往等用户拨打客服电话后才能派人到现场进行处理,造成用户停电时间长。上述现象的发生都会增加运维人员工作量,降低客户满意度。The frequent occurrence of such incidents has greatly increased the work pressure of power grid operation and maintenance personnel. Once a switch trip occurs in a low-voltage power distribution system, due to the lack of monitoring and control methods, it is often not until the user calls the customer service call before sending someone to the scene to deal with it. Cause user power outage for a long time. The occurrence of the above phenomena will increase the workload of operation and maintenance personnel and reduce customer satisfaction.
