Abstract

Abstract: According to the problem that the ice-coating of overhead transmission lines was harmful to the reliability of power transmission, this paper discussed various thermodynamic ice-melting technologies. The basic theory of the thermodynamic de-icing technology was introduced, especially the AC and DC de-icing method, as well as the status quo of AC de-icing schemes and DC de-icing device in China. Through the comparison of the characteristics of various AC de-icing methods and DC de-icing devices applied in AC/DC transmission lines, the application scopes of several de-icing methods were divided, and the future development of the DC de-icing devices was discussed.

Key words: thermodynamic ice-melting, AC de-icing, DC de-icing
