China West Power 220kV transformer series refresh again!

Page view
China XT 220kV class transformer adds new addition! On May 26, SPS-300000/220 three-phase indoor three-winding oil-oil heat exchange forced circulation self-cooling non-excitation voltage regulating power transformer was successfully trial-manufactured by West Power Company, which is the first oil-oil heat exchange system cooling 220 kV power transformer manufactured by West Power Company of China. Its successful trial-manufacture not only adds a new variety to the 220kV transformer of XD brand, refreshes the 220 kV power transformer series, and lays a good foundation for the expansion of Urban Indoor Substation business of West-to-West Power Transformer.
 
 
 
 
This new product is designed for 220 kV Dadu River underground substation of Shanghai Electric Power Company. Its cooling mode and operation mode are very special. Transformer fin radiator and transformer body are layered, and the height difference is about 14 meters. Transformer body oil is cooled by oil-oil heat exchange system, and oil of oil-oil heat exchanger is cooled by self-cooling fin radiator placed upstairs.
 
XXX has carried out scientific research and independent innovation on the basis of its leading domestic technology. Through the study of key technical problems, the technology of technology, manufacture, test, quality control and production management of three-winding combined operation of power transformer are comprehensively mastered. Among them, the proprietary technology of "simulation test method of transformer temperature rise using split cooling mode" is applying for national patent. (Li Jie)
