铁路供电线路的覆冰危害及预防处理

供电导线覆冰会使线路承受过大载荷、相邻跨距覆冰厚度不均,易造成线路拉断、杆塔倒塌等一系列严重危害,必须加以预防及处理。针对导线覆冰现象,提出采用碳纤维复合芯防覆冰导线等措施,论证了在易于出现低温雨雪冰冻灾害地区采用碳纤维防覆冰导线的可行性,有助于降低覆冰对供电线路的安全营运影响。

On the Icing Damage to the Railway Power Supply Circuits and Prevention

As is known to all, when power supply circuits are covered with ice, they will become overloaded. While the circuits between the neighboring spans are covered with uneven ice,it is likely to result in serious damage to the circuits, such as breaking them or making the posts fail, both of which have to be prevented or dealt with. Aiming at fighting against the circuits being covered with ice, the adoption of the anti-icing carbon-core composite circuits is suggested in the paper, with the feasibility of using the anti-icing carbon-core composite circuits in lower-temperature,or snow-stricken regions.
