变压器的温度监控系统设计毕业设计.doc

摘 要 设计以凌阳单片机SPCE0601A为核心，并配以适当的外围芯片与接口电路实现变压器的温度监控。系统采用多组风机对油浸风冷式变压器降温，变压器油温由预埋在变压器油中的铂电阻采集，将采集到的油温在就地和远端实时显示，温度的显示由LED数码管实现。当控制变压器的油温大于上限温度值时，投入全部风机；当油温低于下限温度值时，停止全部风机的运行；变压器的油温介于上限值和下限值之间时,风机按工艺要求运行。可编程RF无线收发器芯片CC1000实现主从机之间的数据传输，使中心控制室及时掌握变压器风机的运行状况，实现远程温度监控。风机出现故障时，相应的发光二极管点亮,并且报警电路发出报警信号。系统要具备完善的过压、过载、缺相检测和保护功能。 关键词： SPCE061A ; 无线通信; 变压器 ;温度监控 Abstract This design is based on the Sunplus MCU SPCE0601A , and go together with the appropriate outer circle chip and interface electric circuit to carry out supervise and control oil temperature transformer on the spot and at the long-distance .This system adopts several group electromotor to cool down the temperature of the transformer.The temperature is collected by the temperature transducer of the platinum resistance , The temperature that is gathered will display at right on the spot and at the long-distance . the manifes
