摘　　要：分析冰灾发生的气候背景等因素,详细阐述国内外目前采用和正在研究的防冰新技术的原理和应用情况,从有效性、安全性、技术性、可操作性和经济性等方面对这些防冰除冰技术及方法进行了综合评估,并对其应用价值和市场前景做出了评估。得到在电网设备的防冰方法中,不存在既具有安全性、可操作性,又能有效且经济的防冰技术的结论。提出在输电网络防冰除冰工作中,应把预防电网冰雪灾害工作放到更加重要的位置,重视输电网络覆冰的理论研究,认真分析冰灾原因,不断研究新技术、新方法,提高防冰水平的建议。The influencing factors of transmission line icing are analyzed. The principles and application conditions of the existing or in-research anti-icing technologies are summarized. All of the anti-icing technologies are comprehensively evaluated in terms of validity, safety, operability, and economical efficiency, and the results indicate that for all of the anti-icing technologies, no one can possess all satisfactory validity, safety, operability, and economical efficiency. It is suggested that emphases be laid on prevention of transmission line icing, including theoretical research on transmission line icing, cause analysis of the icing damage, development of new anti-icing method and technology, and enhancement of anti-icing capability.
