A combined cross-arm structure for power poles and towers and its application method

Abstract

The invention discloses a cross-arm structure for a combined power pole and tower, comprising an upper cross-arm and a lower cross-arm arranged on the pole-tower, the lower side wall of the upper cross-arm and the upper side wall of the lower cross-arm are fixed with suspension Type insulator, the middle part of the upper cross arm and the lower cross arm are provided with installation openings, the outer walls of the upper cross arm and the lower cross arm are provided with two openings communicating with the installation openings, the upper cross arm and the lower cross arm The middle part of the lower cross arm is also provided with a threaded port that communicates with the installation port, and a U-shaped plate is inserted between the two ports, and the U-shaped plate is threaded with fastening bolts that match the threaded port. , Both sides of the upper cross arm and the lower cross arm are provided with baffles located outside the suspension insulator. The present invention shields the wind force by setting baffles, reduces the influence of the air flow on the suspension insulator, and ensures the overall stability. At the same time, when the temperature is low, it triggers the connection between the heating wire and the power supply for heating, avoiding the accumulation of snow and increasing the overall stability. anti-snow ability.

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...

AI Technical Summary

Problems solved by technology

The vertical reinforcement plate and the horizontal reinforcement plate are integral and direct structures. The U-shaped bolt mounting holes are located on the vertical reinforcement plate surface, the pole clamping holes, bracket installation holes and clamping ears are located on the horizontal reinforcement plate surface, and the fastening holes are located on the horizontal reinforcement plate surface. Located on the clamping lugs; although it can prevent birds from nesting and improve a certain strength, the overall ability to resist wind and snow is poor and cannot cope with harsh environments. easy to accumulate snow
