摘　　要：为解决电气化铁路接触网覆冰问题,基于焦耳热效应建立了接触线的热平衡方程,分析了承力索的分流作用对接触网防冰电流的影响,计算了接触网的临界防冰电流。同时基于静止无功发生器SVG(static var generator)在线防冰方案原理,并依托同相供电技术,设计了同相供电条件下的接触网在线防冰方案,仿真验证了方案的可行性,对保证电气化铁路正常运行有重要的实际价值和意义。In order to tackle the problem of electrified railway catenary icing,on the basis of Joule heating and heat transfer process of the contact line icing,the critical anti-icing current is calculated.Catenary load-bearing cable takes into account in the current calculation.Then on the basis of anti-icing scheme by static var generator（SVG） and relying on the existing co-phase power supply technology,anti-icing scheme is proposed and the scheme is validated by simulation.It has a certain significance for ensuring the normal operation of the electrified railway.
