降低电力变压器运行温度

理想运行负载 通常情况下,电力变压器运行的负载在60~70%Se左右(Se—电力变压器的额定视在容量)比较理想,此时变压器损耗较小,运行费用较低。
Under ideal operating load, the load of power transformer is usually about 60-70% Se (rated apparent capacity of Se-power transformer). At this time, the loss of transformer is smaller and the operating cost is lower.
理想功率因数 提高电网的功率因数,有利于变压器的经济运行。
The ideal power factor improves the power factor of the power grid, which is beneficial to the economic operation of transformers.
降低电力变压器运行温度 电力变压器的温升每超过8℃,寿命将减少一半。如果它的运行温度超过变压器绕组绝缘允许的范围,绝缘迅速老化,甚至使绕组击穿,烧毁变压器。
Reducing the operating temperature of power transformer, the life of power transformer will be reduced by half for every temperature rise exceeding 8 C. If its operating temperature exceeds the allowable range of transformer winding insulation, the insulation will rapidly aging, even make the winding break down and burn down the transformer.
