摘要
通过对红花电站4#机定子绕组的直流耐电压试验过程中三相泄漏电流不平衡问题的分析、处理过程的详细介绍,阐述了该电站4#水轮发电机直流泄露电流超标产生的原因,对大型机组在电站安装过程中出现直流泄露电流超标的分析和处理方面提供了宝贵的经验。
Based on detailed introduction on analysis and treating process of three-phase leakage current unbalance occurred in DC high-voltage test of No. 4 generator stator winding of Honghua power station, this paper expounds the reason of overweight current. It can provide valuable experiences for the same condition in large unit installation procedure.
