摘要
冰灾是输电线路面临的最大威胁之一,而融冰技术是防止及减轻冰灾、确保线路安全运行的重要手段。深入讨论了220 kV线路交流融冰技术的基本原理和方案,分析了各方案的利弊。通过广西电网220 kV沙塘—侯寨线路的实例分析计算,提出了初步交流短路融冰方案,供借鉴。
Ice disaster is one of most severe threats to the secure and reliable operati on of transmission system. To alleviate the damage efeect of transmission line icing, ice melting technogoly must be used to remove ice. This paper considers deeply basic principles and schemes of AC short-circuited ice melting technology for 220kV transmission line, analyzes the advantages and disadvantages of all schemes. Finally, one ice melting scheme is proposed primarily for a specific transmission line named 220kV Shatang-Houzhai line in Guangxi power system.
