110～1100 kV GIS常用电流互感器的结构及应用

Commonly Used Transformer Structure and Its Application of 110~1 100 kV GIS

随着气体绝缘开关(GIS)在高压、超高压领域的广泛应用,GIS逐渐趋向小型化、模块化、智能化,对GIS用电流互感器(TA)提出了新的要求,电子式电流互感器的出现为GIS的互感器应用技术提供了新的结构方式。由于不同GIS厂家的GIS结构设计不同,GIS用TA的结构也各有差异。因此,介绍了GIS传统电磁式及电子式TA常用结构及应用,并对各种结构形式进行了对比,为GIS用TA结构的选择提供参考。

With the applications of GIS to the field of high voltage and UHV, GIS has the trend of miniaturization, modularization and intelligence, which put foreword new requirements to the TA for GIS. The emergence of electronic current transformer provides a new structure mode of current transformer application technology for GIS. Different manufactures have different structures of GIS. TA＇s structure for GIS is also different. The common structure of traditional electromagnetic type and electronic type TA and its applications are introduced in this paper. By the comparison between the different structures of TA for GIS, the reference of the structure design of TA for GIS is offered.
