重冰区架空输电线路交叉跨越抗冰措施分析

Analysis of Anti-ice Measures of Overhead Transmission Lines Crossing in Heavy Icing Area

受电力系统规划、地形地质条件、诸多障碍设施及地方政府意见等因素影响,特高压(ultra high voltage,UHV)线路相互之间的交叉跨越越来越常见,重冰区交叉跨越难以避免。本文结合工程实例,分析论述重冰区特高压架空输电线路交叉跨越时的抗冰措施。

Under the influence of power system planning, topographic and geological conditions, many obstacles and facilities, and opinions of local governments, the crossing of UHV transmission lines is becoming more and more common, and it is difficult to avoid the crossing of heavy icing areas. Combined with engineering examples, this paper analyzes and discusses the anti-ice measures of UHV overhead transmission lines crossing in heavy icing area.
