| 摘 要： | 提出了一种高压晶闸管换流阀冷却系统泄漏保护方法,当水冷却系统在一定时间内泄漏量超过换流阀要求的泄漏流量时泄漏保护能正确动作,同时避免由于冷却介质的热胀冷缩而引起误判断,对国内新建直流工程有指导意义。

| Abstract: | A leakage protection method of high voltage thyristor converter valve cooling system is put forward in this paper,in which when the leakage exceeds the quantity that converter valve requested,the leakage protection can act correctively,meanwhile it can avoid wrong judgement resulted from expansion and contraction of cooling medium,which is instructive to new DC engineering. |
