摘　　要：大型机组的轴系温度探头,因其本身安装方式的局限性及其在机组运行时的环境因素,极易造成损坏,从而引起联锁,触发停车,影响整个生产系统的稳定运行。分析轴系温度探头的一般损坏过程,结合信号的变化规律,利用罗克韦尔Trusted系统开放的组态功能,对信号的突变进行处理,解除联锁的同时又能及时反映实际的温度变化并进行报警,防止其造成不必要的停车。The shafting temperature probe of the utility-type unit is easily damaged because of the limitation of its own installation way and the environmental factors in the operation of the unit, thus causing interlocking, triggering parking and affecting the stable operation of the whole production system. Analysis the general damage process of the shafting temperature probe, with the change regulation of the signal and Rockwell trusted control system open configuration function to deal with the mutation of the signal. When the interlock is released, it can reflect the actual temperature change in time and alarm to prevent unnecessary parking.
