关于干式电力变压器负载能力的讨论

Discussion on the Load Capacity of Dry-Type Electric Power Transformers

对影响干式电力变压器负载能力的三个重要因素（环境温度、绕组热时间常数和过负载运行前的起始负载率）分别进行了讨论。这些讨论是以不损失干式电力变压器的正常使用寿命为依据的。在此基础上，对干式电力变压器的使用寿命及寿命补偿问题进行了探讨。

in this paper, three factors which effect on the load capacity of drytype electric power transformers, the surrounding temperature, heat time constant of winding and the initial load coefficient before overload operation, arediscussed respectively. The discussion is base on that the transformers does notlost its normal service life. And the service life and life compensation are studied.
