摘　　要：对ODAF和OFAF两种冷却方式换流变压器的绕组温升和短路强度进行了仿真计算,将仿真结果与试验数据进行对比分析,得出两种冷却方式换流变压器在绕组温升和短路强度方面的优缺点,指出两种冷却方式换流变压器的设计要点。The winding temperature rise and short circuit strength for two kinds of cooling modes of converter transformer are simulated. The advantages and disadvantages of the two cooling systems for converter transformer are gained by comparison analysis of both simulation results and test data. The key design points are drawn from the comparison as well.
