基于原杆塔导线更换为耐热导线的研究

Study on the Replacement of the Original Tower Wire for Heat Wire

随着城市电网的发展,常会遇到输电线路利用原线路走廊架线工程,如需利用旧原线路,但新建线路导线比原旧线型号要大,原有杆塔无法挂新建线路导线,特别是原线路周围有房子的情况,原走廊两边已无法开辟新的通道,以及原走廊在城区拆除麻烦和拆除后无法再架设新塔的情况。为了节省投资,利用旧塔,避免拆除重建,缩短施工时间,如今选择导线更换耐热导线。如何结合导线参数选择耐热导线,选择的导线能否满足输送功率要求,是本文研究的方向,结合相关实际工程应用给予了分析。

With the development of the urban power grid,Often encountered with transmission line using the original line corridors wiring project,If want to use the original old line,But the model of new line wire is bigger than the original old line,the original tower can＇t hang the new line conductor,Especially the original lines around the house and on both sides of the corridor has been unable to open up new channels and the corridor cause trouble by the urban demolition and cannot be dismantled to set up the new tower. In order to save investment,using old tower,avoiding demolish rebuild and shorten the construction time,Now choose heat-resistant conductor to replace wire. How to choose the heat-resistant conductor according to the conductor parameters to meet the requirements of transmission power is the research direction in this article. Combined with practical engineering application of related analysis is given.
