摘要:: 牵引变压器是牵引供电系统最为重要的电气设备之一，其运行的经济性与铁路部门的电费支出密切相关。研究表明，通过提高牵引变压器的过载能力，研制高过载牵引变压器，可使牵引变压器的容量利用率趋于合理，并可以此改善牵引变压器运行的经济性。本文对高过载变压器的相关技术和标准进行了介绍，结合牵引变压器的具体技术需求，提出了两种高过载牵引变压器的技术方案。

Abstract:: Traction transformer is one of the most important electrical devices in the traction power supply system. The economic efficiency of its operation is closely related to the electricity expenditure of the railway sector. The research in this paper shows that through improving the overload capacity of traction transformers and developing high-overload traction transformers, the capacity utilization rate of traction transformers can be rationalized and the economic efficiency of traction transformer operation can be improved. This paper introduces the technologies and standards related to high-overload transformers, and proposes two technical schemes for high-overload traction transformers based on specific technical requirements of traction transformers.
