摘要
输电线路覆冰是困扰输电企业的重要问题。本文以常见的LGJ-70/40,LGJ-240/30和L GJ-400/65等钢芯铝绞线作为研究对象,以传热学相关理论为指导,分析了钢芯铝绞线的融冰物理过程,建立了一种分析输电线路直流融冰时间的融冰模型。
Ice coating on transmission lines is one of the most important problems to power transmission companies.This paper takes the common LGJ-70/40,LGJ-240/30 and L GJ-400/65 steel-cored aluminum stranded wires as the research objects.Guided by the theory of heat transfer,this paper analyzes the physical process of ice melting of steel-cored aluminum stranded wires and establishes an ice melting model for analyzing the DC deicing time of transmission line.
