500kV double-loop compact tension-resistant tower
The invention provides a 500kV double-loop compact tension-resistant tower. The 500kV double-loop compact tension-resistant tower comprises tower legs, a tower body and a tower head which are sequentially connected, wherein the tower head is sequentially provided with a ground wire cross arm, an upper wire cross arm, a right middle jumper wire cross arm, a left middle jumper wire cross arm, a lower wire cross arm and a left lower jumper wire cross arm from top to bottom; the ground wire cross arm comprises a left ground wire cross arm body and a right ground wire cross arm body which are each provided with a jumper wire hanging point; the upper wire cross arm comprises a left upper wire cross arm body and a right upper wire cross arm body which are each provided with a wire hanging point; the lower wire cross arm comprises a left lower wire cross arm body and a right lower wire cross arm body which are each provided with a wire hanging point; and the tower body is further provided with a high-position wire hanging point and a low-position wire hanging point. According to the 500kV double-loop compact tension-resistant tower, three-phase wires of the same loop are arranged in a triangular shape, and the natural conveying power of a line can be improved; and the distance between the wires on the left side and the right side of the iron tower ranges from 7.6m to 10.6m, the distance between the wires on the two sides of a conventional 500kV line angle tower ranges from about 16.0m to 17.5m, the width of a line corridor can be effectively reduced by about 50%, corridor house and structure removal is greatly reduced, investment is saved, and economic benefits are obvious.
一种500kV双回路紧凑型耐张塔，包括依次连接的塔腿、塔身和塔头，塔头从上至下依次设有地线横担、上导线横担、右中跳线横担、左中跳线横担、下导线横担、左下跳线横担；所述地线横担包括左地线横担和右地线横担，均设有跳线挂点；上导线横担包括左上导线横担和右上导线横担，均设有导线挂点；下导线横担包括左下导线横担和右下导线横担，均设有导线挂点；塔身上还设有高处导线挂点、低处导线挂点。本发明中同一回路的三相导线采用三角形布置，可提高线路自然输送功率；本发明的铁塔左右两侧边导线间距在7.6‑10.6m之间，而常规500kV线路转角塔两边导线间距约为16.0‑17.5m左右，能有效压缩线路走廊宽度50%左右，大幅减少走廊房屋及构筑物拆迁，节省投资，经济效益明显。
