GIS局部放电缺陷模拟装置设计与定位技术研究

Design and Location Technology of GIS Partial Discharge Defect Simulator

利用GIS对电力企业变电站进行局部放电检测,可以在一定程度上发现电力设备存在的故障隐患,从而预防重大电力事故的发生。通过对GIS典型局部放电缺陷进行研究,分别进行整体结构设计和内部传感器设计,设计并制作出一款全新的GIS局部放电缺陷模拟装置。再将该装置应用于实践,通过GIS局部放电缺陷信号处理、GIS局部放电缺陷区域判断实现对局部放电缺陷位置的定位,以期为电力企业中变电站的安全运行提供技术条件。

Using GIS to detect partial discharge in power enterprise substation can detect the hidden trouble of power equipment to a certain extent,so as to prevent the occurrence of major power accidents.Based on the research of typical partial discharge defects in GIS,the overall structure design and internal sensor design are carried out,and a new GIS Partial Discharge defect simulation device is designed and manufactured.Then the device is applied to practice,through the GIS Partial Discharge defect signal processing,GIS Partial Discharge defect area judgment to achieve partial discharge defect location,in order to provide technical conditions for the safe operation of substation in power enterprises.
