本文论述了我国电气化铁道防干扰技术的现状,参照日本电气化初期采用吸流变压器以及自耦变压器的历史原因,结合我国具体条件,即根据电化区段地理条件和通信线路受影响情况,提出了采用吸流变压器、自耦变压器、同轴电力电缆和特设回流线装置,作为供电系统防干扰技术措施的意见。文中对上述措施的应用场合、防护原理及优缺点进行了分析。
In this paper, the status quo of anti-interference technology of electrified railway in our country is discussed. Referring to the historical reasons of using suction transformer and autotransformer in the initial stage of electrification in Japan, combined with the specific conditions in our country, namely, according to the geographical conditions of electrification section and the influence of communication lines, Suction flow transformers, autotransformers, coaxial power cables and special return line devices, as the technical advice of the power supply system against interference. In this paper, the application of the above measures, the protection principle and advantages and disadvantages were analyzed.
