摘　　要：利用直流电源下树脂浇注绕组电阻可以由电压和电流比值直接实时求得的特性,对树脂浇注干式变压器的热时间常数和绕组最终平均温升与负载率的关系进行了研究。The relationship between the thermal time constant, the final average temperature rise of the winding and the load ratio of the resin-cast dry-type transformer is studied by using the characteristics that the resistance of the resin-cast winding can be directly obtained by the ratio of voltage to current under the DC power supply.

关 键 词：树脂浇注干式变压器 热时间常数 过负荷能力
