【Abstract】 The mathematic model of 2D nonsteady-state temperature distribution of dry-type transformer was established.The temperature distribution in one phase of transformer was solved by the finite difference method.The temperature rise characteristics of core,LV coil and HV coil,as well as whole temperature distribution and the location of the heatest spot were analysed and calculated.更多还原
