一起换流站阀水冷系统故障问题分析及处理

Fault Analysis and Treatment of Valve Water Cooling System in a Converter Station

换流阀运行时,阀体会通过大电流产生高温,阀水冷系统作为对阀主体及各个元器件冷却的主要系统,对换流站安全稳定运行有着十分重要的作用。对换流站阀水冷系统及水冷控制保护系统进行了介绍,对现场故障问题进行了分析和处理,并更深入地进行了问题探讨,可为直流控制保护设备检修提供一些思路和方法。

When the converter valve was running,the valve body would generate heat through large current.As the main cooling system for the valve body and each component,the valve water cooling system played a very important role in the safe and stable operation of the converter station.This research introduced the valve water cooling system and water cooling control and protection system of the converter station,analyzed and processed the on-site fault problems,and conducted in-depth discussion of the problem,in order to provide some ideas and methods for the maintenance of DC control and protection equipments.
