摘　　要：发电机漏氢监测装王监测的对象是定子绕组水内冷系统及其封闭母线和密封油系统的密封性,它具有早期故障报警的重要作用。该装王的基本要求是能够长期稳定工作,对故障不误报、不漏报。文章对国内目前占有较大市场的钯栅氢敏传感器型和热导型二大主要漏氢监测装置从工作原理及使用效果等方面进行了一些对比分析,便于发电厂进行设备运行、维护和选购时参考。The monitoring device of generator hydrogen leakage has the important function for the earlier warning of fault. The basic requirements for this device are to be able to stabilize work for a long period, not mistake and fail to report for the earlier warning of fault. This paper analyzes the working principles and application effects of two major hydrogen leakage devices, hydrogen sensing transducer with palladium grid and thermal conductivity, which possess the greater home market now. It is convenient for power plant to operate, maintenance and choose the equipments as reference.
