摘　　要：由于换流站换流阀冷却系统冷却介质在高电压电场下循环运行,冷却介质必须具备极低的电导率,本文分析了基于电去离子处理技术的去离子方案,与传统混床离子交换工艺相比,具有去离子效率高、使用寿命长、产水电导率低等优点,能更有效减缓换流阀内部器件腐蚀、沉积等影响,在换流站冷却系统设计时可以参考使用。There is a fact that the cooling medium of converter valve cooling system in converter station is circulating under high voltage electric field,the cooling medium must have greatly low conductivity.This paper analyzes the deionization method based on the electrodeionization technology.Compared with the traditional mixed bed ion exchange process,it has the advantages of high deionization efficiency,long service life and low water conductivity,which can more effectively reduce the corrosion and deposition of internal components of converter valve.Therefore It can be used for reference in the design of cooling system of converter station.
