摘要 随着电力系统的快速发展,企业和用户对电能的需求逐渐增大。为满足企业和用户使用需求,必须增加电能的生产和分配。近年来,GIS变电站凭借较大优势被大量新建,与此同时,作为电能计量装置之一的配套GIS电流互感器的检定工作也随之增加。GIS电流互感器的校验已经成为一个热门课题。本文主要介绍了3种GIS电流互感器测试技术原理,即比较法、低压外推法以及负荷仿真外推法。在现场同一条件下,对这3种测试原理设备的测试数据进行对比,并比较基于3种不同原理设备的优缺点,最后提出了电流互感器误差检测的趋势。

Abstract:With the rapid development of power system, the demand for electrical energy of enterprises and users is increasing. In order to meet the needs of enterprises and users, the production and distribution of electric energy must be increased. In recent years, the GIS substation has been built a lot by virtue of its great advantages. At the same time, the verification of the GIS current transformer is also added as one of the energy metering devices. The verification of GIS current transformer has become a hot topic. This paper mainly introduces the testing principle of three kinds of GIS current transformer, that is, comparison method, low voltage extrapolation method and load simulation extrapolation method. Under the same condition in the field, the test data of three kinds of testing principle and equipment are compared, and the advantages and disadvantages of the equipment based on the three different principles are compared. Finally, the trend of current transformer error detection is proposed.
