摘要
根据电气铁道牵引负荷的不对称、谐波和波动特性，本文提出了当前常用的六种牵引变压器的不对称、谐波和波动损耗的统一计算式和对于两供电臂机车运行方式的损耗曲线，并进行了计算比较。文中还提出了减小不对称、谐波和波动对电力系统的影响和提高牵引变压器运行经济性的共同要求。
According to the asyrnmetrical、har-monic and fluctuating features of traction load,in elec-trified railways in this paper the comrnon formulasare put forward for calculating the asymmetrical,har-monic and fluctuating losses in six kinds of tractiontransformers which are frequently used in electrifiedrailways. ThOse losses are calculated and comparedwith each other.The common requirements of miti-gating the influence of the asymmetry, harrnonics andfluctuation of loads on power system and that of rais-ing the operational efficiency of traction transformersare also presented.
