输电线路覆冰防治措施分析

Analysis on Prevention Measures Against Wire Ice Covering for Transmission Lines

受地理位置及气候变化的影响,多个地区的输电线路在途径覆冰重灾区时覆冰事故频发,并且随着电压等级的不断提高,输电线路对覆冰灾害的影响更为敏感,极易发生断线、倒塔等事故,严重影响电能的正常输送。因此,通过分析现有覆冰防治措施的特点及差异,提出改善输电线路覆冰防治的新方向。

Because of the geographical location and the impact of climate change,the transmission lines in several areas of China are heavily affected by multiple ice cladding accidents and frequent ice cladding accidents.With the continuous improvement of voltage level,transmission lines are more sensitive to the impact of ice disaster,easy to bring about line break and tower fall accidents,and seriously affect the normal supply of electric energy.In view of the above problems,the characteristics and differences of existing ice cover prevention measures are analyzed,based on which the development direction of ice cover prevention measures for transmission lines are put forward.
