| 摘 要： | 针对大亚湾核电站和岭澳核电站的常规岛凝结水系统凝结水泵因进、出口差压大和差压开关长期工作在高差压的环境下容易损坏,导致保护系统跳闸的问题,通过分析和计算,提出了将凝结水泵的气蚀保护由差压保护改为出口压力保护的改进方案,解决了差压开关容易发生故障的问题.改进实施后,效果良好,现场没有发生类似故障.

| Abstract: | Aiming at tripping of protection system caused by huge differential pressure between the inlet and outlet of condensate pump of condensate system in conventional islands of Dayawan nuclear power station and Lingao nuclear power station as well as vulnerability of differential pressure switch that works in high differential pressure environment for long,the paper proposes to substitute exit pressure protection for differential pressure protection,settling the problems that there are frequent faults in differ... |
