目前,如何对覆冰接触导线进行融冰、除冰以及降低冰灾损失是世界性的技术难题,通常的融冰措施分为热融冰、机械除冰及自然脱冰。该文总结了目前国内外接触网除冰技术的研究现状,介绍了接触导线覆冰的危害、覆冰的性质。根据铁道机车和接触网的特殊结构,本文提出采用机械除冰和热力除冰相结合的接触网除冰方法,详细阐述了除冰装置的结构原理和安装方法,并指出了接触网除冰技术的未来发展方向。
At present, it is a worldwide technical problem that how to melt and de-icing ice-covered contact wires and reduce the loss of ice damage. Common ice melting measures include hot melt ice, mechanical ice deicing and natural ice removal. This paper summarizes the current research status of the contact network deicing technology at home and abroad, introduces the hazards of contact line icing and the nature of icing. According to the special structure of railway locomotive and catenary, this paper proposes a method of catenary deicing using a combination of mechanical deicing and thermal deicing, detailing the principle of the deicing apparatus and its installation method. It also points out that catenary deicing The future direction of development.
