The invention discloses a vibration-reduction composite cross arm electric rod with a cross arm convenient to replace. The electric rod comprises an electric rod body, a middle-phase hoop set and an edge-phase hoop set are installed on the electric rod body from top to bottom, the middle-phase hoop set is composed of a middle-phase preparation-position hoop and a middle-phase operation-position hoop which are arranged up and down, and the edge-phase hoop set is composed of an edge-phase preparation-position hoop and an edge-phase operation-position hoop which are arranged up and down; edge-phase composite cross arm fixation positions are symmetrically arranged at the two sides of the edge-phase preparation-position hoop and the two sides of the edge-phase operation-position hoop along thecentral axes of the hoops, and middle-phase composite cross arm fixation positions are arranged at one side of the middle-phase preparation-position hoop and one side of the middle-phase operation-position hoop. According to the vibration-reduction composite cross arm electric rod providing convenience for replacement of the cross arm, the problems can be solved that replacement is complex, and fatigue damage easily occurs; the construction efficiency is improved, and possibly-caused personal injuries and possibly-caused area economic losses are avoided; meanwhile, the high-frequency low-amplitude effect of aeolian vibration of a wire on the composite cross arm through an insulator chain is reduced, and the service life of the composite 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...
