Single loop phase-adjustable on-off tower
A single loop phase-adjustable on-off tower comprises a tower body, a top ground wire cross arm, an upper wire cross arm, a middle wire cross arm and a lower wire cross arm, and further comprises an upper auxiliary wire cross arm and a middle auxiliary wire cross arm. The structural composition and a wiring form of a single loop overhead line on-off tower with a different phase sequence are included. The situation that a built single loop line is turned on and off by a newly built base pole tower can be achieved. The phase sequence of wires at both sides of a double loop line formed after on-off is arranged in a different phase sequence, thereby reducing the spatial electric field strength of the wires. The tower is mainly suitable for new angle steel tower lines in non-urban areas, hills,and mountains. Compared with the prior art, the tower solves the shortcomings of the suspension string deviation, the large number of newly built pole towers and the same phase sequence of the wiresat both sides.
本发明的一种单回路可调相开断塔，包括塔身、顶层地线横担、上层导线横担、中层导线横担、下层导线横担还包括上层辅助导线横担、中层辅助导线横担；本发明包括单回架空线路异相序开断塔的结构组成和接线形式，可实现新建基杆塔将已建单回路线路开断的情况，并且开断后形成的双回线路两侧导线相序按异相序布置，可降低导线空间电场强度；主要适用于非城区及丘陵、山地等新建角钢塔线路；与现有技术相比解决了悬垂串偏移、新建杆塔数量多和两侧导线相序相同的的缺点。
