摘　　要：对神华神东电力有限责任公司萨拉齐电厂2号机组发电机漏氢事故进行分析,通过压力试验及漏氢量检测,确定原因为汽端密封瓦磨损导致发电机漏氢量增大。通过更换新密封瓦,对发电机轴颈进行微弧焊修补处理后,2号机组密封油系统运行正常,发电机漏氢量达到良标准,确保了机组的安全稳定运行。Make an analysis of hydrogen leakage accident in generator 2 in Shenhua Shendong Salaqi Power Plant Units. Through a pressure test and detecting the amount of hydrogen, the author determined the steam-side seal the watt wear resulted in generator hydrogen leakage amount increasing. Thus, replace new sealed watt and repair the generator with micro arc welding. After transformation, the normal operation of Unit 2 reach to the normal level and prevent generator hydrogen leakage accidents, which can offer reference for the same type of units.
