Embodiment Construction

[0017] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0018] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected ...

Abstract

The invention discloses a door-type suspension guyed tower and a method. The door-type suspension guyed tower comprises a first tower body, a second tower body, a stayguy and two V-shaped insulator strings, wherein the first tower body and the second tower body are separated and are adjacently arranged; the stayguy comprises a first end, a second end and a middle part, the first end is arranged onthe outer side face of the first tower body and is connected with a stayguy foundation arranged on the ground, the second end is arranged on the outer side face of the second tower body and is connected with the stayguy foundation arranged on the ground, and the stayguy penetrates through the top of the first tower body and the top of the second tower body; and the two V-shaped insulator stringsare hung between the first tower body and the middle part of the stayguy as well as between the second tower body and the middle part of the stayguy correspondingly, and the V-shaped insulator stringsare used for hanging a wire. The guyed tower can solve the problem of deformation of a cross arm of a self-standing door-type tower, has the advantage of small inter-pole gap of the doo-type tower, and can avoid the torque.

Description

technical field [0001] The invention relates to a door-type suspension cable stay tower and a method thereof, which are used in direct current transmission lines and belong to the technical field of transmission lines. Background technique [0002] figure 1 Shown is a self-supporting portal tower for DC transmission lines, which is mainly composed of two tower bodies and a cross arm connected between the two tower bodies. Compared with the conventional "T" or "horn" type suspension For the tower, it can reduce the pole spacing, reduce the torque, and can fully save the line corridor and protect the environment. However, the cross-arm bears a lot of force, and the problem of deformation of the cross-arm often occurs. In addition, the existence of the cross arm increases the lateral bending moment of the iron tower. In addition to the wind load, there is also a bending moment generated by the vertical load of the wire, and the torsion force is relatively large. Contents of...
