摘要

在现代智能电网的智能化变电站中

电子式电流互感器逐渐取代传统的电磁式电流互感器

得到越来越广泛的应用。暂态特性是保护用电流互感器的重要性能

文中针对不同原理的电流互感器的暂态特性进行了相关的试验研究。首先概述了电磁式电流互感器的暂态保护TPY级和电子式电流互感器暂态保护TPE级的定义及试验要求

然后通过实际的试验

对不同原理的多台电流互感器的暂态特性进行比对

得到多组比对试验数据。试验结果表明:电子式和传统电磁式的电流互感器都能达到标准要求的暂态性能指标

对用户的选型及生产厂家的设计均有指导意义。

Abstract

In the modern smart grid intelligent substation

the electronic current transformers gradually replace thetraditional electromagnetic current transformers and get more and more widely used. Transient characteristics are im-portant for the protection of current transformers. In this paper

the transient characteristics of current transformerswith different principles are studied by actually test. Firstly

the definition of TPY class for electromagnetic currenttransformer and TPE class for electronic current transformer are overviewed

and then the transient characteristics ofmultiple current transformers with different principles are compared though actually test. The test results show thatthe electronic current transformers and the traditional electromagnetic current transformers all can meet the standardrequirements of transient performance indicators. This discussion may be useful to manufacturers and users.
