500kV line engineering single-circuit lightning arrester straight pole tower in high altitude area
A 500kV line engineering single-circuit lightning arrester straight pole tower in a high altitude area comprises a pole tower body and a wire cross arm arranged at the top of the pole tower body, the wire cross arm is composed of a middle cross arm and side wire cross arms connected to the two ends of the middle cross arm, and a pair of lightning arrester supports are overhung at the ends of the side wire cross arms respectively, three-phase wire hanging points are arranged on the lower surfaces of the middle cross arm and the side wire cross arm, a middle-phase wire is connected to the middle-phase wire hanging point on the lower surface of the middle cross arm, two-phase side-phase wires are connected to side-phase wire hanging points on the lower surface of the side wire cross arm, and the side-phase wire hanging points are located at the ends of the side wire cross arm, the support end of the lightning arrester support is connected with the lightning arrester body, the side phase wire and the lightning arrester body are located on the same plane, and the side phase wire is located below the lightning arrester body. The tower has a better lightning protection effect, the problem that the alternating-current line single-loop tangent tower is poor in lightning protection effect is solved, and the application range of the 500kV alternating-current single-loop tangent tower is widened.
一种高海拔地区500kV线路工程单回路避雷器直线杆塔，包括杆塔主体以及设置在杆塔主体顶部的导线横担，所述的导线横担由中横担以及连接在中横担两端的边导线横担组成，并且边导线横担的端部各悬挑出一副避雷器支架，中横担和边导线横担的下表面设置三相导线挂点，中相导线连接在中横担下表面的中相导线挂点上，两相边相导线连接在边导线横担下表面的边相导线挂点上，边相导线挂点位于边导线横担的端部，避雷器支架的支架端头连接避雷器本体，所述的边相导线与避雷器本体处于同一平面且边相导线位于避雷器本体的下方。本发明具有更好的防雷效果，解决了交流线路单回路直线塔避雷效果差的问题，拓宽了500kV交流单回路直线塔的适用范围。
