摘　　要：凝汽器是核电站二回路的重要设备之一,检漏装置又是凝汽器的“眼睛”,其设计的目的就是实时监测并快速判断凝汽器设备是否循环冷却水泄漏。而凝汽器检漏装置异常报警会影响正常的监测,通过排查发现光电液位开关缺陷与电源模块缺陷是造成异常报警的主要因素,可以通过技改换型减少异常报警,从而保障检漏装置的正常实时监测。Condenser is one of the essential equipment in the secondary circuit of the nuclear power plant and leak detection device is the “Eye”of the condenser, which is designed to monitor in real time and quickly determine the circulating cooling water leakage of the condenser.However, Abnormal alarms of the condenser leak detection device which are mainly triggered by the defects of photoelectric level switch and power module will disturb the normal monitoring. As the abnormal alarms can be reduced by technical improvement, the normal real-time monitoring of the leak detection device is ensured.
