摘　　要：[目的]文章旨在解决换流站阀冷喷淋水水质破坏导致系统故障问题。[方法]分析了水质破坏机理及常规直流换流阀冷却喷淋水对管路破坏的过程,研究提炼出水处理内容。[结果]研究成果为柔性直流换流阀冷却喷淋水提出一种优化反渗透处理技术方案,可高效去除喷淋水中破坏管路的各个因素。[结论]该处理工艺出水基本杜绝喷淋水在冷却塔盘管外壁结垢及其他水质破坏的问题,确保整个阀冷系统可靠的冷却效能和稳定的运行。[Introduction] The paper aims to solve the problem of system failure caused by quality destruction of valve cooling spray water in converter station. [Method] This article analyzed the water quality damage mechanism,analyzed the process of LCC valve cooling spray water to the pipeline damage,researched out the content needed to be removed. [Result] Propose an optimization reverse osmosis treatment plan for VSC valve cooling spray water. Efficient removal of the various factors in the spray water that damage pipeline. [Conclusion] The spray water will not scale on the cooling coils or generate other damage by treated with the solution,and ensures reliable cooling performance and stable operation of the valve cooling system.
