摘要
压油装置油温高的异常现象在水电站中时有发生,分析了乐滩水电厂2#机组出现压油槽油温异常现象的原因,提出减少机组负荷、减小导叶开度漂移、增加机组的协联死区、加强辅助散热等措施作为解决办法。
Pressure oil tanks of hydropower plant frequently see excessive high oil temperature. The author ana- lyzed the causes for unit No.2 of Letan Hydropower plant which also had this problem, and suggested as solution to reduce unit load and drift of gate opening, extend the on-cam dead zone, improve heat ventilating facilities.
