Abstract

The invention discloses a cross arm structure for a combined power tower. The cross arm structure comprises an upper cross arm and a lower cross arm which are arranged on the tower, suspension insulators are fixed to the lower side wall of the upper cross arm and the upper side wall of the lower cross arm correspondingly, and mounting openings are formed in the middle of the upper cross arm and the middle of the lower cross arm correspondingly; two through openings communicating with the interiors of the mounting openings are formed in the outer walls of the upper cross arm and the lower crossarm, threaded openings communicating with the interiors of the mounting openings are further formed in the middles of the upper cross arm and the lower cross arm, a U-shaped plate is jointly insertedbetween the two through openings, and fastening bolts matched with the threaded openings are in threaded connection with the U-shaped plate; and the two sides of the upper cross arm and the two sidesof the lower cross arm are each provided with a baffle located on the outer sides of the suspension insulators. By means of the cross arm structure, the baffles are arranged to shield wind power, theinfluence of air flow on the suspension insulators is reduced, the overall stability is guaranteed, meanwhile, connection between a heating wire and a power source is triggered for heating when the air temperature is low, accumulated snow accumulation is avoided, and the overall wind and snow resistance is improved.

Description

technical field [0001] The invention relates to the technical field of pole and tower cross arms, in particular to a combined power pole and tower cross arm structure and a use method. Background technique [0002] The angle iron fixed horizontally on the top of the utility pole has a porcelain vase on it, which is used to support the overhead wire. The function of the cross arm: The cross arm is an important part of the tower. Its function is to install insulators and fittings to support the wires and lightning conductors and keep them at a certain safe distance according to regulations. [0003] Authorized notification number CN205422124U discloses a reinforced structure wire crossarm, which belongs to the technical field of electric equipment, and consists of a vertical reinforcement plate, a U-bolt mounting hole, a horizontal reinforcement plate, a pole clamping hole, a bracket mounting hole, a clamping lug and Composition of fastening holes. The vertical reinforcement...
