摘要
主变冷却器是降低变压器温度,减少绝缘老化、提高使用寿命的主要设备,冷却器可靠与否直接影响主变压器的安全运行。文章通过对岩滩水电站主变冷却器控制方式的发展进行论述,分析主变冷却器从常规控制方式发展为PLC控制方式的运行状况,着重介绍PLC可编程控制方式的特点,并对存在的问题提出见解。
The cooler of the main transformer is the main equipment to lower the transformer＇s temperature,reduce insulation aging and enhance the service life. Reliable work of the cooler or not directly affects the safe operation of the main transformer.This article discusses the control mode of the main transformer cooler of Yantan Hydropower Station which develops from normal control to PLC control,focuses on characteristics of PLC control,and provides solutions for problems involved.
