摘　　要：介绍了输电线路覆冰在线监测系统的结构和功能,综述了国内外覆冰在线监测方法及其存在的问题,证明了称重法静力学计算模型的科学性,简化了导线倾角法计算流程。最后指出,进一步的研究方向是优化称重法计算模型、改进间接测量方法、准分布式和分布式光纤传感技术的应用。The structure and functions of a online monitoring system for ice coating on overhead transmission lines are presented, and the methods to monitor ice coating on overhead transmission lines home and abroad are summarized and defects in these methods are pointed out. The reasonableness of statics calculation model for weighing method is proved and the calculation process of wire obliquity method is simplified. It is pointed out that the further direction in the research of online monitoring of ice coating on overhead transmission is optimizing statics calculation model for weighing method, improving indirect measurement methods and applying quasi-distributed and distributed optical fiber sensing technologies to overhead transmission lines.
