【Abstract】 The distribution of the temperature field and the flow field in steady-state condition is derived for a cable transformer’s coil by solving the finite element equations Based on this,the thermal circuit model by taking a turn as unit in transient condition is built up The variation of the coil’s temperature rise in transient condition can be calculated by using this model The study provides a feasible way to investigate the temperature characteristics for the cable transformer更多还原
