摘　　要：研究了利用电流热效应对柔性接触网进行防冰冻的方案,首先分析了几种利用牵引整流机组和能馈装置的方案以及利用独立电流发生装置进行防冰冻的方案,并比较两者的优缺点。在此基础上,提出降低能馈装置容量的思路和方法,并对不同防护范围下的情况进行总结。This paper studies the anti-icing scheme of the flexible catenary by using the current thermal effect.First,it analyzes several schemes using the traction rectifier unit and the energy-feeding device and the anti-icing scheme using the independent current generating device,and compares the advantages and disadvantages of the two.On this basis,ideas and methods for reducing the capacity of the energy-feeding device are proposed,and the situations under different protection ranges are summarized.
