摘　　要：随着电力系统的快速发展,近年来对城农网大力改造使得配网设备数量逐年增长,相关的检测工作量急剧增加,对试验设备集成化和测试效率要求越来越高。尤其是对数量大、种类多的10 kV配变,现有的10 kV配变三相局放试验设备较多,现场测试的大量时间花在接线上,给试验工作带来了极大的不便。基于上述现场试验中存在的实际问题,提出了对10 kV配变三相局放试验设备进行一体化改造方案,并构建了典型故障识别模型,实现了对典型的局部放电干扰和局部放电图谱的智能分析。With the rapid development of the power system,the vigorous transformation of urban and rural power grids in recent years has made the number of distribution network equipment increase year by year,the related testing workload has increased sharply,and the requirements for the integration of testing equipment and testing efficiency have become higher and higher.Especially 10 kV distribution ATN-NETs have a large number and variety.There are more than 30 three-phase partial discharge test equipment for 10 kV distribution ATN-NETs.A lot of time for on-site testing is spent on wiring,which brings great inconvenience to the test work..Based on the practical problems existing in the above field tests,an integrated transformation plan for the three-phase partial discharge test equipment of 10 kV distribution ATN-NET is proposed,and a typical fault identification model based on ATNNET is constructed to realize the typical partial discharge interference and partial discharge.Intelligent analysis of graphs.
