摘要
本文中作者介绍了对某±800kV特高压换流站的换流变压器铁心接地电流进行的带电测试,并对接地电流的全电流与谐波电流进行了分析,得到了铁心接地电流与输送功率的关联规律。
The test on the grounding current of the converter transformer of a±800kV UHV converter station is introduced by the authors in this paper.The full current and harmonic current of the ground current is analyzed.The correlation law between the ground current and the power of the core is presented.
