摘要
推导了变压器突发短路工况后短路电流的全电流及其稳态分量作用下绕组平均温度的计算公式,并进行了实例计算,同时将所求得的温度与标准中的温度进行对比,得出短路电流持续时间、稳态短路电流倍数与绕组温升之间的变化规律。
The calculating formula of winding average temperature with the action of all short-circuit and its steady component in transformer under short-circuit condition is deduced. The examples are calculated. The result is compared with standard. The change law about the winding temperature with the short-circuit current duration and the steady short-circuit current ratio is concluded.
