摘　　要：配电开关设备结构复杂,发生故障时不仅查找机构卡涩点位困难、原因分析与处理须要花费大量的检修时间,还缺乏对驱动机构卡涩隐患的提前预警措施,给配网运维和检修工作带来很大负担。该项目通过分析储能电机运作时的电流波形,利用自身正常状态波形与不同状态波形进行相似性度量,设定边界阈值,从而实现对配电开关的正常、卡涩和断线情况进行辨识,实现故障的智能诊断,提升运维智能化水平。The structure of distribution switchgear is complex.When a fault occurs,it is difficult to locate the points of mechanical sticking,and the analysis and handling of the causes require a significant amount of maintenance time.Additionally,there is a lack of early warning measures for the hidden risks of sticking in the drive mechanism,which places a heavy burden on the operation and maintenance of the distribution network.This project analyzes the current waveform during the operation of the energy storage motor,utilizing the normal state waveform and different state waveforms for similarity measurement,and setting boundary thresholds to identify the normal,sticking,and disconnection conditions of the distribution switchgear.This enables intelligent diagnosis of faults and enhances the level of intelligent operation and maintenance.
