基于一二次融合开关的架空配电线路断线故障预测

Overhead Distribution Line Disconnection Fault Prediction Based on Primary and Secondary Fusion Switch

由于气象灾害、线路老化和外力破坏等原因,断线故障呈多发态势。断线故障会对正在配网线路上作业的带电作业人员和旁路作业人员带来人身伤害事故,对各类负荷造成严重影响,易导致火灾和人畜触电危害,扩大停电范围,后果严重。对断线情况进行预警预测,能够及早处理避免形成故障,保障作业人员的人身安全,更大程度上提高供电可靠性和电网安全性。文章通过对断线发展阶段的现象进行分析,结合近年来大量应用的一二次融合柱上开关成套装置检测的信息,提出断线故障预测的方法。

Due to meteorological disasters,line aging and external damage and other reasons,the line fault is frequent.The broken line fault will bring personal injury accidents to the live workers and bypass workers working on the distribution network line,cause serious impact on all kinds of loads,easily lead to fire and electric shock harm of people and livestock,and expand the scope of power failure,with serious consequences.Early warning and prediction of the broken line situation can deal with it as early as possible to avoid forming faults,ensure the personal safety of operators,and improve the reliability of power supply and power grid security to a greater extent.The paper analyzes the phenomenon of the breaking development stage and combines the detection method of the prediction of the breaking fault in this paper.
