The Engineering Analysis And Research Of Leakage Flux Field And Temperature Rise On Metal Parts For Power Transformer

The low loss and overheating control for power transformer is very important at present in order to ensure safety operation for power system. How to research stray losses and temperature rise on metal parts caused by leakage flux is difficult task for transformer design. Today, Increasing of capacity per unit of transformer has been accompanied by enlargement of power net system, So research subject mentioned above is very useful and important.Research and summary for stray losses and overheating control on metal parts caused by leakage flux of transformer has been given by author in this article through a lot of tests on site, Meanwhile , The analysis has been given by electrical-magnetic theory also. Some important practice formulae and conclusions are made only because the distribution of leakage flux of transformer is complicated.The engineering research and test result for stray losses and temperature rise on metal parts caused by leakage flux of transformer is very useful for transformer design and improving reliability of transformer operation.
