介绍了GIS电磁电压互感器交接绝缘试验现状和相关要求,并以工程现场试验工作需求为出发点,基于电力变频技术设计研制了一套便携式多功能倍频感应耐压装置,代替传统三倍频电压发生器和空载励磁电流测量装置,同时实现了对电磁式电压互感器感应耐压试验和空载电流测量功能。新装置有效保障了现场试验的安全性和准确性,缩短了现场试验时间和减少了试验人力投入,提高了工作效率。

The status and requirements of insulation acceptance test for the electromagnetic voltage trans-former of GIS are introduced firstly. according to the requirement of the field test work,a portable multi-pur-posed inductive withstand voltage device for double frequency is developed based on power frequency-variable technology to replace the traditional frequency tripled voltage generator and no-load excitation current mea-surement unit and in the meantime implement the inductive withstand voltage and no-load current measure-ment test for the electromagnetic voltage transformer. The safety and accuracy of the field test are effectively guaranteed,the time and labor of the field test are reduced, and the work efficiency is improved.
