Inverted L-shaped double-loop terminal rod

Abstract

The invention discloses an inverted-L-shaped double-loop terminal pole which comprises a steel pipe pole, a first cross arm, a second cross arm, a third cross arm and a fourth cross arm, and the first cross arm, the second cross arm, the third cross arm and the fourth cross arm are located on the same side of the steel pipe pole, one end of the first cross arm is fixed with the peripheral surface of the top end of the steel pipe pole, the second cross arm, the third cross arm and the fourth cross arm are sequentially arranged below the first cross arm in parallel at intervals from top to bottom, one ends of the three cross arms are fixed to the peripheral face of the steel pipe pole, the first cross arm is a ground wire cross arm, and the second cross arm, the third cross arm and the fourth cross arm are all wire cross arms. The invention provides a very economical solution for the pipeline position conflict problem. The size of the steel pipe pole head is optimal, and the steel pipe pole head is more stable and convenient to construct. The steel pipe pole body and the cross arms are reasonable in appearance design, the appearance change rule is similar to the internal force change rule of components, and the performance of materials is fully exerted, so that material waste is reduced, and engineering investment is reduced.

Description

technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to an inverted L-shaped double-circuit terminal pole. Background technique [0002] With the continuous development of the power grid, the newly built 110 kV overhead transmission line usually adopts double-circuit construction. Where the overhead transmission line is routed along the existing road, steel pipe poles are generally used in the form of pole towers; and there are often many pipelines on both sides of the road, such as Power pipe trenches, rain and sewage pipes, gas pipelines, communication pipelines, etc. will encounter the problem of conflict between the position of the pole and its foundation on the path of the transmission line and the position of the existing buried pipeline. There are usually two solutions, one is to change the route of the transmission line and add a corner pole, which will increase the project investment; the other solution i...

Problems solved by technology

There are usually two solutions, one is to change the route of the transmission line and add a corner pole, which will increase the project investment; the other is to relocate the pipelines that affect the construction of the transmission line, which will not only increase the difficulty of project construction , increasing the construction period, and the cost of relocating other pipelines is also higher
