Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage power transmission lines, in particular to a windproof suspension string for communication equipment. Background Art

[0002] In recent years, wind deflection flashover accidents of suspension insulator strings of power grid high-voltage transmission lines are one of the prominent problems that frequently occur in power grid failures. Wind deflection accidents are a major safety hazard to the normal operation of the power grid, and the line is not easy to reclose successfully after a wind deflection fault, which seriously affects the normal operation of the power grid and causes significant economic losses. The excessive wind deflection angle of the suspension insulator string is the direct cause of the wind deflection accident. Therefore, a windproof suspension string for communication equipment is proposed.

[0003] A windproof biased suspension string is disclosed in the publication number CN209844500U. Although the windproof biased suspension string is installed on the transmission tower through a cross arm, the ZBS hanging plate is installed at the end of the cross arm, a ball head hanging ring is installed below the ZBS hanging plate, a rod-shaped composite insulator is installed below the ball head hanging ring, a bowl head hanging plate is installed below the rod-shaped composite insulator, a suspension wire clamp is installed below the bowl head hanging plate, and an upper fixing plate is fixedly installed below the cross arm near the end of the ZBS hanging plate A spring device is installed on the lower surface of the upper fixing plate, and a lower fixing plate is fixedly installed on the upper part of the rod-shaped composite insulator. The lower fixing plate swings with the swing of the rod-shaped composite insulator. The lower fixing plate is correspondingly arranged to the upper fixing plate. When the wind deflection angle of the rod-shaped composite insulator exceeds 10°, the lower fixing plate contacts the lower end of the spring device, which can effectively reduce the wind deflection angle and avoid discharge of the conductor due to insufficient electrical distance when the wind deflection angle is too large. The wind deflection flicker of the suspension string is effectively controlled, and the safe and reliable operation of the transmission line is guaranteed.

[0004] However, the windproof partial suspension string has the following disadvantages: when in use, it is not easy to connect two groups of wires at different distances, and additional tools are needed to operate, which affects the work efficiency of the staff. Utility Model Content
