摘要
阀冷系统可对阀片进行冷却,是直流换流站的重要组成部分。通过对历史运行数据进行统计分析,得出了某±800 kV换流站运行过程中阀冷系统内冷水稳压装置频繁出现氮气消耗过快缺陷的原因,并提出了相应的改进措施。
The valve cooling system can cool the valve plate,which is an important part of dc converter station.Based on the statistical analysis of historical data,the reason why the nitrogen consumption was too fast occurred in the stabilizing device of valve cooling system during the operation of±800 kV converter station was analyzed,and the corresponding improvement measures were put forward.
