摘要
分析了现行电力变压器冷却系统现状及存在的问题,提出了基于可编程控制器为控制核心实现运算、逻辑功能的控制,采用变频调速技术方案,使冷却系统能够跟随温度及负荷电流的变化连续平滑调整,有利于变压器的安全运行。
The present condition of control system and existing problem of cooling system for power transformer were simply analyzed. A control scheme was put forward,which was based on programmable controller and could fulfill operation and control of logic function. With frequency convertion variable speed technology scheme, the cooling system could follow the variation of temperature and load current to be continuously and smoolthly regulated. It would benefit the safe operation of transformer.
