一起特高压换流站阀冷系统补水故障处理与分析

Treatment and Analysis of Replenishment Fault of Valve Cooling System in UHV Converter station

换流站阀冷系统是特高压直流输电工程中重要的辅助设备,在阀冷系统持续地散热降温下换流阀才能保持正常运行。文章介绍了一起发生在苏州换流站阀冷系统的工业水补水故障,属于典型的水冷系统故障类型。文中针对故障发生情境、故障发生原因和现场的处置措施进行分析,提出了后期维护和改进方案。

The valve cooling system of converter station is an important auxiliary equipment in UHVDC transmission project.The converter valve can maintain normal operation only when the valve cooling system continues to dissipate heat and cool down.This paper introduces an industrial water make-up fault of valve cooling system in Suzhou converter station,which belongs to a typical fault type of water cooling system.This paper first explains the fault situation,analyzes the causes and on-site disposal measures,and finally puts forward the scheme forlater maintenance and improvement.
