摘　　要：阀水冷系统作为特高压换流站的重要组成部分,担负着冷却换流阀的作用,是保证直流系统正常运行的根本。本文以特高压换流站阀水冷系统设计、施工为切入点,对相关规程规范未涉及但可能影响设备安全稳定运行的重要隐患进行深度挖掘,提出相应整改和防范措施,确保运维阶段阀水冷系统的长期安全稳定运行,有效提升直流输电系统可靠性。Valve cooling system is an important part of UHV converter station with the fuction of cooling and converter valves, it is foundation to ensure the normal operation of UHV system. Based on the UHV DC converter valve cooling system design and construction stage, this paper analyzes some hidden danger which could affect long-term operation, and put forward the corresponding corrective and preventive measures to ensure equipment safe and stable operation. It can effectively improve the reliability of DC transmission system.
