摘　　要：随着电力互感器的快速发展与广泛应用,各类型电力互感器校验仪的研究得到了广泛重视,但在应用过程中均发现了一些不足,因此,便携式通用电力互感器校验仪的研制应运而生。本文首先对电力互感器的发展及现有校验仪的基本特点进行了介绍,进而提出便携式通用电力互感器校验仪的概念,之后给出了系统的总体框图,并就设计中的难点进行了分析,最后给出了研制结果,并对研制过程中存在的问题提出了改进方向。With the rapid development and application of instrument transformer, various instrument transformer calibrators have been widely utilized, but there are still some shortages for those calibrators. Therefore, the study of portable transformer calibrator is urgently required. In this paper, the development of instrument transformer and the performance analysis of different transformer calibrators are presented firstly, and then the concept of portable general transformer calibrator is put forward. After that, the system diagram of calibrator is illustrated, and some key questions are discussed during the design course. At last, the paper presents the research results, and simultaneously discusses the problems and the future direction.
