Embodiment 1

[0030] In the technical solutions disclosed in one or more embodiments, such as figure 1 As shown, a replacement tool for replacing horizontally arranged cross-arms of tension poles with electricity, including horizontal insulating cross-arms 2 and vertical insulating cross-arms 3, and the vertical insulating cross-arms 3 are sequentially arranged in horizontal positions according to set intervals. Horizontal and lateral arrangement is realized on the insulating cross arm 2;

[0031] The lower end of each vertical insulating cross arm 3 is provided with at least two adjustable connecting plates 5 with a set distance apart, and the adjustable connecting plates 5 are used for fixed connection with the tension insulator connection hanging plate.

[0032] This embodiment uses the horizontal insulating cross arm 2 and the vertical insulating cross arm 3, the horizontal insulating cross arm is used to provide a horizontal support structure, the vertical insulating cross arm is used ...

Embodiment 2

[0048] Based on the tool in Embodiment 1, this embodiment provides a method for replacing the cross-arm of horizontally arranged tension poles with electricity, including the following steps:

[0049] Step 1. Disconnect the tension insulator connection plate on the line from the original cross arm, use the replacement tool in Example 1 to connect the tension insulator connection plate, and fix the tension insulator connection plate to the insulator and the bow wire. And lift to the set height;

[0050] Step 2, replace the new cross arm, the replacement tool described in embodiment 1 will vertically drop the lifted wires, insulators and fittings to the original position;

[0051] Step 3. Turn the three-phase bow wires down to the original position; separate the tension insulator connection hanging plate from the tool described in Embodiment 1, and fix the tension insulator connection hanging plate on the new cross arm.

[0052] When the line is not powered off, the tool of Emb...

Abstract

This disclosure proposes a replacement tool and replacement method for live replacement of horizontally arranged tension pole cross-arms. The replacement tool includes horizontal insulating cross-arms and vertical insulating cross-arms. The vertical insulating cross-arms are sequentially arranged according to the set spacing Set on the horizontal insulating cross-arm to achieve horizontal and horizontal arrangement; the lower end of each vertical insulating cross-arm is provided with at least two adjustable connecting plates at a set distance, and the adjustable connecting plates are used to connect the hanging plates with the strain insulators Fixed connection. The horizontal insulating cross arm of the replacement tool is used to provide a horizontal support structure, and the vertical insulating cross arm is used as the main load-bearing structure. After stretching the insulators and lines, the safe distance between the tension insulators and the lines between the three phases can be maintained.

Description

technical field [0001] The present disclosure relates to the related technical field of electric power equipment, and in particular, relates to a replacement tool and a replacement method for live replacement of horizontally arranged cross-arms of tension poles. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] At present, there are defects in the cross-arm or insulator string of 10kV triangular arrangement tension poles. The commonly used operation method for replacing the tension insulator string and cross-arm is as follows: install a new tension cross-arm, fittings and insulator string at an appropriate position above the original cross-arm , Complete the wire transfer work after insulation and shielding, and then remove the old insulator string and cross arm to complete the replacement of the cross arm or insulator string. [0004] Th...
