Problems solved by technology

The wind deflection of jumper is a form of wind-induced disaster. The main type of single-circuit transmission line is relatively small, the insulator string is relatively long, and the shape of the jumper is more complicated. Only theoretical calculations are carried out without real-type tests, resulting in deviations between theoretical calculations and actual operating conditions, and jumper wind deflection faults are prone to occur at small corners

Embodiment 1

[0029] Such as Figure 1-2 As shown, this embodiment provides a single-circuit dry-shaped strain tower tower head-jumper true test device, including: a single-circuit dry-shaped strain tower and a load support, and the single-circuit dry-shaped strain tower The load brackets are set on both sides of the tower, and the load bracket and the tower head of the single-circuit dry-shaped strain tower are equipped with several jumper hanging points for carrying jumpers, which can be adjusted by the jumper hanging points on the load bracket. The jumper's rotation angle and height difference are matched with different voltage levels, different heights and other working conditions through the jumper on the tower head, so as to obtain the relevant test results of the jumper under different working conditions.

[0030] In this example, if image 3 As shown, the middle is a single-circuit dry-shaped strain tower, and the single-circuit dry-shaped strain tower includes a tower head, a towe...

Abstract

The invention discloses a single-loop strain tower head-jumper real-model test device shaped like Chinese character 'gan' under different working conditions, the test device comprises a single-loop strain tower shaped like Chinese character 'gan' and load supports arranged on two sides of the single-loop strain tower shaped like Chinese character 'gan'. The load supports and the tower head of the single-loop strain tower shaped like Chinese character 'gan' are respectively provided with a plurality of jumper wire hanging points used for carrying jumper wires, the rotating angle and the height difference of the jumper wires are adjusted through the jumper wire hanging points on the load supports, and working conditions such as different voltage grades and different heights are matched through the jumper wire hanging points on the tower head, therefore, jumper installation test results under different working conditions are obtained. The jumper wire installation real-model test is carried out under the working conditions of different height differences, different rotation angles, different voltage grades and the like of the jumper wires, installation and design of the jumper wires are guided, and the wind deflection problem of the strain jumper wires shaped like Chinese character 'gan' of the single-circuit power transmission line is solved.

Description

technical field [0001] The invention relates to the technical field of single-circuit dry-type tension towers, in particular to a single-circuit dry-type tension tower head-jumper true type test device. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The conductive device connecting the tension clamps of the conductors on both sides of the strain tower is the jumper wire of the overhead transmission line, and the jumper string is used to ensure that the charged wire and the conductive part of the tower maintain a sufficient electrical distance. The wind deflection of jumper is a form of wind-induced disaster. The main type of single-circuit transmission line is relatively small, the insulator string is relatively long, and the shape of the jumper is more complicated. Only theoretical calculations are carried out without real-type tests, r...
