A power grid engineering cable support device

Abstract

The invention discloses a power grid engineering cable supporting device, which includes: a power grid tower column, a connecting horizontal frame, a wire wheel set, a side support component and an upper fastening crimping line component; wherein, the power grid tower column is erected vertically On the ground, the two sides of the upper end surface of the grid tower column are symmetrically fixed with connecting horizontal frames for connecting and erecting grid cables, and one end of the connecting horizontal frame is equipped with a conductor wheel set; and, the grid tower Side support components are installed symmetrically on both sides of the upper end of the column, and the side support components provide vertical support for the lower part of the power grid cables; The left and right ends of the above fastening and crimping assembly are erected between the guide wheel set and the side supporting assembly respectively, and are in contact with the upper end of the grid cable.

Description

Technical field [0001] The present invention relates to the technical field of power grid engineering equipment, specifically to a power grid engineering cable downshort device. Background [0002] High-voltage power grid is an important component of the power system, in the high-voltage grid erection project overhead transmission line is a more common way, by erecting the wire in the air way can reduce the power grid erection of the land occupation area, the current power grid erection of high-voltage lines through the tower for overhead, and in the grid cable rack in the air, affected by the weight of the cable itself leads to the grid cable prone to sinking phenomenon, so that the power grid cable in the tower connection to produce relaxation, while in the long-term overhead action, The cable will be tensile deformation by the tensile force at the sinking place, and when it is severe, it will lead to direct fracture of the power grid cable; and in the constantly changing envir...

AI Technical Summary

Problems solved by technology

[0002] The high-voltage power grid is an important component of the power system. Overhead transmission lines are a relatively common way in the construction of high-voltage power grids. By erecting wires in the air, the land occupation area in power grid erection can be reduced. Currently, high-voltage power grids are erected Most of the lines are overhead through the tower, and in the overhead power grid cable, due to the influence of the weight of the cable itself, the grid cable is prone to sinking, which makes the power grid cable loose at the connection of the tower, and at the same time, the long-term overhead effect Under normal circumstances, the cable will be stretched and deformed under the action of tension at the sinking place, and in severe cases, the power grid cable will be directly broken; and in the constantly changing environment, it is easy to produce stretching and shaking, which will affect the normal power transmission work; therefore, those skilled in the art A power grid engineering cable supporting device is provided to solve the problems raised in the above-mentioned background technology
