Vibration-attenuating compound cross arm pole with conveniently replaced cross arm

Abstract

The invention relates to a vibration-attenuating compound cross arm pole with a conveniently replaced cross arm. The vibration-attenuating compound cross arm pole comprises a pole body. A middle phase hoop group and a side phase hoop group are mounted from top to bottom of the pole body. The middle phase hoop group is composed of a middle phase preparatory position hoop and a middle phase operating position hoop which are arranged up and down; the side phase hoop group is composed of a side phase preparatory position hoop and a side phase operating position hoop which are arranged up and down; side phase compound cross arm fixing positions are symmetrically arranged on two sides of the side phase preparatory position hoop and the side phase operating position hoop along the axis of the hoop; and a middle phase compound cross arm fixing position is arranged on one side of the middle phase preparatory position hoop and the middle phase operating position hoop. The vibration-attenuating compound cross arm pole with the conveniently replaced cross arm provided by the invention can solve the problem of complicated replacement and likely fatigue damage, the construction efficiency is increased, and possible human damage and regional economical loss are avoided; meanwhile, a high frequency low amplitude effect applied to the compound cross arm by means of an insulator string through aeolian vibration of a wire is alleviated, and the service life of the compound cross arm is prolonged.

Description

technical field [0001] The invention relates to the field of power transmission line engineering, in particular to a vibration-absorbing composite cross-arm electric pole which is convenient for replacing the cross-arm. Background technique [0002] In the transmission pole, the cross arm of the pole is a very important component. It plays an important role in connecting the pole body, supporting the insulator string to suspend the wire, and maintaining the electrical distance between the wire and the pole. Due to its light weight, excellent electrical performance, and excellent properties such as reducing the amount of steel used in power grid transmission systems, FRP composite crossarms are widely used in power transmission towers and are one of the directions for the development and construction of power grids. However, there are still many deficiencies and problems to be solved in the research. Among them, the anti-aging performance (acid, alkali, salt) and thermal st...
