单片机在变压器三备一系统中的应用

Application of Single Chip Microcomputer in Transformer Three Preparations and One System

介绍利用译码器与单片机设计制作大型变压器三备一时的指示与控制电路。当备用变压器因为人为操作工作在非正常模式时,通过声光效果发出报警来提示操作人员恢复,保护设备,并避免引起不必要的故障。

This paper introduces the method of designing and making three main transformers to share a standby transformer. The switching of the standby transformer is controlled by a decoder or a singlechip.When the standby transformer works in abnormal mode by human operation. Hint to the operator by the sound and light effect. To protect devices and avoid unnecessary failures.
