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

The invention provides a replacement tool and a replacement method for live-line replacement of a horizontally-arranged tension-resistant electric pole cross arm, and the replacement tool comprises ahorizontal insulating cross arm and a vertical insulating cross arm, wherein the vertical insulating cross arm is sequentially arranged on the horizontal insulating cross arm according to a set interval to realize horizontal transverse arrangement; the lower end of each vertical insulating cross arm is provided with at least two adjustable connecting plates which are spaced by a set distance, andthe adjustable connecting plates are used for being fixedly connected with a tension insulator connecting hanging plate. A horizontal insulation cross arm of the replacement tool is used for providinga horizontal direction supporting framework, a vertical insulation cross arm is used as a main body force bearing structure, and the vertical insulation cross arm is connected with a tension insulator connecting hanging plate on each phase of line, so after the tool fixes a tension insulator and the line, and the safety distance between the strain insulator among three phases and a line can be kept.

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...
