Problems solved by technology

Compared with plain areas, these areas with complex terrain are not only more difficult to construct, but also difficult to meet the electrical, mechanical and economic performance of the conductors, ground wires and transmission towers of electrical lines at the same time.
[0003] The terrain in mountainous areas is generally more complex; the transmission towers used in the transmission lines in mountainous areas generally need to be designed according to the uphill terrain, meteorological conditions, electrical requirements, mechanical requirements, etc.; due to the influence of hillside terrain, each transmission tower The slope of the tower is not the same. In the process of using the staggered cross-arm tower, it needs to be designed separately according to the terrain of the hillside, and the design workload is relatively large.
Since each tower is designed according to the terrain conditions of the tower location, due to the different cross-arm specifications, it is difficult to assemble on site

Embodiment 1

[0034] Such as figure 1 As shown, the present invention provides an assembled staggered cross-arm straight tower, including a tower body and a cross-arm vertically arranged with the tower body; the tower body includes an upper tower body 9 and a lower tower body 10; The upper tower body 9 is in a vertical direction; the cross arms are staggeredly distributed on both sides of the upper tower body 9 .

[0035] The cross-arms on both sides of the tower body respectively include ground wire cross-arms and wire cross-arms distributed from top to bottom; The cross arm 7; the wire cross arm on the right side includes the upper right wire cross arm 4, the right middle wire cross arm 6, and the right lower wire cross arm 8; the left ground wire cross arm 1 is arranged on the upper side of the left upper wire cross arm 3; The right ground wire cross arm 2 is arranged on the upper side of the upper right wire cross arm 4 .

[0036] The vertical height of the ground wire cross arm is eq...

Embodiment 2

[0048] Such as figure 2 As shown, based on the unified inventive concept, the present invention also provides a method for erecting the above-mentioned prefabricated split-level cross-arm straight tower, the method comprising the following steps:

[0049] (1) The lower tower body 10 is fixed to a predetermined vertical tower area;

[0050] (2) The upper tower body 9 is fixedly connected to the top of the lower tower body 10 and the upper tower body 9 is kept vertical;

[0051] (3) Install the cross arm on the upper tower body 9 and adjust its hanging point.

Abstract

The invention provides an assembled staggered floor cross arm tangent tower and a tower erection method thereof. The assembled staggered floor cross arm tangent tower comprises a tower body and crossarms perpendicular to the tower body, the tower body comprises an upper vertical tower body and a lower tower body, and the cross arms are distributed on two sides of the tower body in a staggered manner. According to the technical scheme, the tangent tower is suitable for a power transmission line in a mountainous area with the slope gradient below 40 degrees, the shielding failure lightning withstand level of the line is improved, the lightning trip-out rate of the whole line is reduced, design reworking is decreased, tower field assembly difficulty is reduced, and construction efficiency isimproved.

Description

technical field [0001] The invention relates to a power transmission straight tower, in particular to an assembled staggered cross-arm straight tower and a method for erecting the tower. Background technique [0002] With the demand and popularization of electricity, transmission lines have gradually extended to remote areas with complex terrain. Compared with plain areas, these areas with complex terrain are not only more difficult to construct, but also difficult to satisfy the electrical, mechanical and economic performance of the conductors, ground wires and transmission towers of electrical lines at the same time. [0003] The terrain in mountainous areas is generally more complex; the transmission towers used in the transmission lines in mountainous areas generally need to be designed according to the uphill terrain, meteorological conditions, electrical requirements, mechanical requirements, etc.; due to the influence of hillside terrain, each transmission tower The ...
