±800kV换流变压器的局放试验双端加压技术分析

Analysis of Double end Pressurization for Partial Discharge Test of ±800kV Converter Transformer

阐述±800kV换流变压器的局放试验,对实验中变压器两端电感值的调整、励磁变压器变比的调整、双变频电源的调整的问题进行模拟,并与现场测试装置进行对比。

This paper describes the partial discharge test of ± 800k V converter transformer,simulates the adjustment of inductance values at both ends of the transformer,the adjustment of excitation transformer ratio,and the adjustment of dual frequency conversion power supply in the test,and compares it with the field test device.
