Problems solved by technology

[0003]In general, the connection and fixation of the ground wire damping wire of the transmission line is wound with metal wire, which is exposed in the atmosphere and is vulnerable to various corrosive gases, ultraviolet rays, frost, rain and rivers. Corrosion of the water vapor above causes a fracture, resulting in a short circuit to the ground of the transmission line

Embodiment Construction

[0016] The specific embodiment of the present invention is as figure 2 , image 3 shown.

[0017] The embodiment of the present invention adopts the protection device for the ground wire and the damping wire of the transmission line to protect the ground wire and the damping wire of the transmission line. The protection device for ground wire and damping wire is composed of two symmetrical rectangular protection blocks 3. The rectangular protection block 3 is made of cast aluminum. The rectangular protection block is embedded with a semicircular groove. The outer diameter is the same, and the upper and lower ends of the rectangular block-shaped protective cover 1 are processed with sealing grooves along the upper edge; the sealing ring 2 with a rectangular cross-section is embedded in the sealing grooves on the inner surface of the upper and lower ends of the protective cover, and the protective cover is tightened evenly. , wrap the protective device tightly and clamp and f...

Abstract

The invention provides a method for preventing a damping wire of a ground wire of a transmission line from breaking. According to the method provided by the invention, by utilizing a protecting device (3) consisting of two rectangular protective blocks which are arranged in a bilateral symmetry mode, corrosion destruction of various corrosive gases, ultraviolet rays, moral integrity rainwater and water steam above a stream of the outside on the ground wire (1) of the transmission line and the damping wire (3) are isolated, thus improving the corrosion resistance and breaking resistance of the damping wire of the ground wire of the transmission line, achieving the purpose of durability of the damping wire of the ground wire of the transmission line, and improving the corrosion resistance of the damping wire of the ground wire of the transmission line. With the adoption of the method, the corrosion resistance to metals of the damping wire of the ground wire of the transmission line is obvious, accidents of power failure in a large area due to grounding short circuit faults of the transmission line due to breaking of the damping wire of the ground wire are prevented, the grid power transmission and distribution safety production level is increased, and the method is suitable for protecting the damping wire of the ground wire of the transmission line.

Description

technical field [0001] The invention relates to a method for preventing a ground wire damping wire of a transmission line from breaking, and belongs to the technical field of high-voltage transmission line operation, maintenance, and repair equipment. Background technique [0002] The function of the damping wire of the ground wire of the transmission line is to prevent the vibration of the ground wire of the transmission line. It is an indispensable and important component in the transmission and distribution network. It is an important guarantee for the safe production of the line, and its safe operation is directly related to the safety and stability of the power grid and the reliability of power supply to users. [0003] In general, the ground wire damping wire of the general transmission line is wound with a metal wire, which is exposed to the atmosphere and is susceptible to corrosion by various corrosive gases, ultraviolet rays, frost, rain, and water vapor above th...
