摘　　要：文章介绍了PLC在变压器风冷系统中的应用。解决了变压器风冷系统中冷却器的投切靠人工监视手动投切、操作不便的问题;实现了根据变压器负荷大小、油温高低进行最优化判断,自动投入或退出冷却器的运行;节省了电能,提高了变压器风冷系统的寿命;系统具有完善的保护、监控、显示及通信功能。This paper introduces the application of PLC in wind - cooling system of the power transformer. It solves the problem, which is depended on manual work in condenser use, and improves automation level. According to the burden of the transformer and the temperature of the oil, the system can work on optimal control and improve the life of the machine. It has perfect function of protection, monitor, show and communication.
