| Abstract: | Short circuit process is a transient process.On the one hand,the temperature increase gives rise to both expansion of windings and reduction of the elastic modules of windings.In order to strengthen the ability to withstand short-circuit of transformer,some problems ,which need to be considered in design,technology,structure and assembly,etc.of transformer,were discussed through the analysis of electromagnetic force generated in windings of transformer.Corresponding proposals for materal were presented. |
