汽动给水泵交流润滑油泵电气联锁回路改造

Electrical Interlocking Circuit Transformation of Steam Feed Pump and AC Lubricating Oil Pump

对马鞍山当涂发电有限公司汽动给水泵交流润滑油泵实际运行中存在的问题、改造方法进行叙述,提出发电厂低压辅机电气联锁回路设计的新思路,并获得改造效果,运行情况良好;可对存在相似问题的低压辅机电气联锁回路改造提供参考。

The paper describes the existing problems and transformation methods of AC lubrication oil pump practical operation in DangTu Ma Anshan power company limited,puts forward a low voltage auxiliary electric power new idea of interlocking circuit design,get information effect and run in good condition,and also provide the reference for similar problems existing within the industry for low voltage auxiliary electrical interlocking circuit transformation.
