摘　　要：针对调相机机械通风冷却塔风机在原有的温度控制上,出现的单台冷却塔风机长期间歇运行影响使用周期寿命的问题。提出了一种机械通风冷却塔风机周期切换控制方法,通过设计修改风机启停方式,增加三台风机的启动标志位的标记和周期切换投入等方式,给出了一台、二台风机的启动条件、周期切换撤出条件以及六种情形下的风机周期切换条件和方法,以此实现三台风机的交替运行与周期切换。The mechanical draft cooling tower fans of synchronous condenser cannot be controlled in the original temperature control method.Periodic switching cannot meet the demands by the original temperature control method.A periodic switching control method for mechanical draft cooling tower fans is proposed in this paper.The start conditions of one and two fans and the withdrawal conditions of the periodic switching control are given by changing the start and stop mode of the fans,marking the start flag of the three fans and increasing the periodic switching button.Through the above methods,the alternative operation and periodic switching of the three fans have been realized in different six situations.
