摘　　要：电力机车通过接触网获取电能,接触网一旦覆冰,会影响机车授流,甚至造成列车停运,危害电气化铁路运行安全。为此,探讨结冰期保证电气化铁路安全稳定运行的接触网融冰技术,其现实意义十分重大。直流融冰技术在电网输电线路中已有成熟应用,但在接触网系统中尚未大规模推广,缺少工程验证。本文提出一种移动式接触网直流融冰装置技术方案,给出其系统结构设计,并对整流单元进行仿真,验证其接入系统的可行性,同时给出系统控制和保护设计,为直流融冰的工程应用提供参考。The catenary mainly transports electrical energy for electrified railways.It will affect the normal operation of electrified railways and endanger the safety of railway transportation when the catenary is severely covered with ice.Therefore,exploring the ice melting technology of the overhead contact system is of great practical significance for ensuring the safe and stable operation of electrified railways.DC ice melting technology has been widely used in power grid transmission lines,but it has not been widely promoted in overhead contact system and lacks engineering verification.This article proposes a technical solution for a mobile overhead contact line DC ice melting device,provides its system structure design,and simulates the rectifier unit to verify its feasibility of being connected to the system.At the same time,it simultaneously provides system control and protection design,serving reference for the engineering application of DC ice melting.
