本文根据苏联先进经验,扼要地介绍电力铁道供电系统设计的基本原则,必要步骤,与计算方法。包括供电设备容量之选择,牵引变电所初步分佈方案之擬定,接触網最经济截面积的计算及各方案的经济比较与最后确定等以经济计算为中心环节的整个设计过程。在我国最近所进行的电力铁道初步设计中经讨论研究,基本上採用了上述计算方法,通过具体实践,证实经济计算之结果,在一定程度上的确符合于技术运行条件之要求,因而更进一步说明其实现意义,可供今后工作上的参考。唯由于学习苏联还很不够,实验经验尤感缺乏,掛一漏万,谬误在所难免,希望能获得指正。
Based on the advanced experience of the Soviet Union, this article briefly introduces the basic principles, necessary steps, and calculation methods for the design of power railway power supply system. Including the selection of power equipment capacity, the preliminary distribution plan of traction substation, the calculation of the most economic cross-sectional area of catenary, and the economic comparison and final determination of various schemes. The whole design process centered on economic calculation. In our country recently conducted the preliminary design of the power railway discussed and studied, basically adopted the above calculation method, through the practice, confirmed that the results of economic calculations, to some extent indeed meet the technical requirements of the operating conditions, and thus further instructions Its meaning, for future reference work. Only because of learning the Soviet Union is still not enough, experimental experience is particularly scarce, hanging one count, fallacy is inevitable, hoping to get correct.
