Description

Single-change double-ground-wire tower head ground wire support structure

Technical Field

The utility model relates to a transmission line technical field especially relates to a single become two ground wire tower head ground wire supporting structure.

Background

With the development of economy and the increase of power load requirements, the reconstruction of established lines is increased day by day, however, a high-voltage overhead line erected in an early stage is erected by using a single ground wire, at present, the high-voltage overhead line is erected by adopting double ground wires, when double ground wires of a newly erected iron tower are butted with a single ground wire of an old line, although a wire hanging hole of the ground wire is formed in the newly erected iron tower, the iron tower is designed to adopt the double ground wires to carry out lightning protection on a wire, the requirement can be met when a ground wire support is lower in height relative to a cross arm of the wire, but if the single ground wire is hung, the height of the existing iron tower ground wire support is insufficient, so that the protection angle of the single ground wire which is butted to the old line side of the old line to the.

The person skilled in the art is dedicated to solving the above technical drawbacks.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned drawbacks of the prior art, the technical purpose of the present invention is to solve the problems mentioned in the background art.

In order to realize the technical purpose, the utility model provides a single become two ground wire tower head ground wire supporting structure, including horizontal cross arm, vertical cross arm and wiring board, horizontal cross arm is used for installing two ground wires and transverse arrangement in the both sides of circuit, vertical cross arm is used for installing a ground wire and vertical arrangement in the centre of circuit, horizontal cross arm with vertical cross arm's front and back terminal surface has arranged respectively the wiring board.

Preferably, the transverse cross arms and the vertical cross arms are arranged in a cross shape.

Preferably, the height of the vertical cross arm is greater than the height of the transverse cross arm.

Preferably, the wiring board on the vertical cross arm is positioned at the center of the line.

Preferably, at least 3 holes are formed in the thread hanging plate.

The utility model has the advantages that:

the utility model discloses because above-mentioned structural design, can satisfy old circuit and newly-built circuit butt joint department (single ground wire and two ground wire butt joint condition) ground wire to the requirement of the angle of protection of wire, guarantee the operation of circuit safe and reliable.

Detailed Description

The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.

Example (b):

as shown in fig. 1-6, a single-change double-ground-wire tower-head ground wire support structure (also commonly referred to as a "support type" in the industry) includes a transverse cross arm 1, a vertical cross arm 2 and a wire hanging plate 3, wherein the transverse cross arm 1 is arranged in the middle of the ground wire support, and is fixedly connected with a bolt by using an angle steel, and two ground wires can be arranged on two end faces; the vertical cross arm 2 is arranged at the top of the ground wire support and fixedly connected with a bolt by using angle steel, the top end face of the vertical cross arm can be provided with a ground wire, and the front side face and the rear side face of the horizontal cross arm 1 and the front side face and the rear side face of the vertical cross arm 2 are respectively provided with a wire hanging plate 3.

Specifically, when a single ground wire is erected on a line, the ground wire can be erected on the upper end face of the vertical cross arm 2, and double ground wires can be erected on two ends of the transverse cross arm 1.

Specifically, the vertical cross arm 2 needs to be higher than the horizontal cross arm 1, and the height of the vertical cross arm 2 needs to be set according to the protection angle of a single ground wire to the lead; the height of the transverse cross arm 1 needs to be set according to the protection angle height of the double ground wires to the lead.

Specifically, 4 holes can be formed in the wire hanging plate 3 on the transverse cross arm 1, 2 holes are used for wire hanging holes, and 2 holes are used for mounting holes; the thread hanging plate on the vertical cross arm 2 can be provided with 3 holes, the middle hole is used for a thread hanging hole, and the 2 end holes are used for mounting holes.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
