Abstract
In allusion to the problem of lack of theoretical basis for reinforcement strategy for windproof stay wires of 1 0 kV distribution lines,this paper makes a numerical study on the reinforcement strategy for windproof stay wires of double circuit distribution lines. It builds a pole-wire coupling finite element model of the strain section and analyzes deformation,rebar stress and stay wire stress of the pole of two strategies including reinforcement of all sections installing windproof stay wires and interval installation of windproof stay wires under different wind speeds. It compares calculation results of the proposed model with the result of unreinforcement of windproof stay wires and discusses reinforcement effects of different strategies. It indicates that installation of windproof stay wires for all sections can improve wind resistance ability of the distribution line while interval installation is insufficient in promoting wind resistance ability of the strain section. It also points out in the ac-tual engineering,it is better to adopt the reinforcement strategy of all section installation for strong typhoon areas as far as possible.关键词
