摘要

与传统电磁式互感器相比

电子式互感器在带宽、绝缘结构和体积等方面更具优势

已成为电力测量设备中的研究热点。随着电网中非线性负荷的增多

谐波污染日益严重

实现对谐波的准确测量意义重大。在此背景下

开展电子式互感器的谐波传变特性研究十分必要。笔者从各种典型电子式电压互感器的工作原理出发

从理论上得出了不同原理的电子式电压互感器能否测量谐波电压的定性结论

为进一步开展电子式电压互感器谐波传变特性的试验及检测研究奠定了基础。

Abstract

Compared with the traditional Electromagnetic Transformer

the electronic transformer has advantages on bandwidth

insulation structure

size

etc. It has become a research hotspot among the electrical equipment for measurement. With the loads in the grid accrues

the harmonics pollution in the grid is increasingly serious

so it has great significance to measure harmonics accurately. In this contest

It’s necessary to explore harmonic transfer Character istics of electronic transformer. Based on the operation principles of various electronic voltage transformers（EVTs）

the harmonic and DC transfer characteristics of EVTs are analysed. The problem whether different kinds of EVTs can be used to measure harmonic voltage is answered theoretically. This study may lay the foundation for test and measurement of EVTs’ harmonic transfer characteristics.
