Economic Operation Modes of Transformers

分析了电力变压器负荷与损耗的关系 ,通过计算 ,寻求变压器运行中降低变压器的有功功率损耗和提高其运行效率以及提高变压器电源侧功率因数的方法。通过对负荷电流与临界负荷电流进行比较 ,合理选择 35kV终端站和 10kV配电变压器的运行方式 ,达到减少变压器损耗的目的。

The relation between transformer loads and losses is analyzed in this paper. The author suggests a way to calculate and find how to increase power fator by reducing transformer losses and increasing its operation efficiency. By comparing load current and critical load current, appropriate operation modes for main transformers in 35kV terminal substations and 10 kV distribution transformers can be selected to minimize transformer losses.
