摘　　要：阀冷系统作为高压直流输电换流站内最主要的辅助设备,对换流阀的正常运行至关重要。以广泛应用的换流阀水冷系统为例,结合部分因水系统异常引发的直流输电系统运行事故案例,总结了典型的几类阀冷系统缺陷类型,给出事故预防的对应策略,为提高阀冷系统的运行可靠性提供参考。Valve cooling system is the major auxiliary system in HY DC converter station and it plays an important role in the normal operation of the converter valve. Taking the widely used water cooling system as an example, combining with some DC system operation failures caused by valve-cooling system exception, it concludes some typical defect types. Meanwhile, the corresponding preventive measures are given as references to enhance the operation reliability of the valve cooling system.
