西门子 LOGO！在主变压器风冷系统上的应用--以水布垭电厂为例

摘要

The SIEMENS LOGO!programmable logic controller ( PLC) is installed in the air cooling system of the main transformer in Shuibuya Hydropower Station , which could be used to monitor the operation condition of each cooler on-line.It would be of great help for maintenance staff to switch the working mode of the coolers periodically and maintain or replace them accurately .%通过为主变冷却器加装可编程逻辑控制器，对主变冷却器风扇运行工况进行在线监测，有效掌握每组冷却器运行工况，以便于电厂维护人员定期切换冷却器工作方式和对冷却器进行定向维护和更换。
