Overhead transmission line tension adjusting wire clamp

Abstract

The invention relates to an overhead transmission line tension adjusting wire clamp, which comprises a mounting rack, a connecting rack and wire clamp assemblies, wherein the mounting rack is mounted on a power transmission tower, the connecting rack is mounted at the lower end of the mounting rack, and the wire clamp assemblies are uniformly mounted on the lower end face of the connecting rack. According to the invention, the problems that when an existing power transmission line is laid, generally, the power transmission line is fixedly installed on a power transmission tower, when the power transmission line is affected by the external environment, tension adjustment cannot be conducted on the power transmission line, the power transmission line is prone to breakage due to long-time stress, and power transmission safety and stability of a power grid are affected can be solved; and the problems that when an existing power transmission line is laid, the power transmission line cannot be effectively insulated, an insulating piece is prone to breakdown, the insulating piece loses the insulating capacity to conduct electricity, the power transmission safety of the power transmission line is affected, and the like can be solved.

Description

technical field [0001] The invention relates to the field of overhead transmission lines, in particular to a clamp for adjusting the tension of an overhead transmission line. Background technique [0002] Transmission lines play an important role in the power grid. The safe and stable operation of transmission lines is related to the stability of the entire power grid; overhead transmission lines are exposed to the atmospheric environment and will be directly affected by meteorological conditions. Transmission lines must have certain mechanical strength to adapt to the local temperature. changes, severe storms, icing loads, and possible flooding when crossing rivers. At the same time, lightning strikes, rain, wet fog, and natural and industrial pollution will also damage or reduce the insulation strength of overhead lines and even cause power outages. [0003] At present, when the existing overhead transmission lines are laid, the following defects usually exist: 1. When th...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that when the existing transmission lines are laid, they are usually fixedly installed on the transmission towers. When the transmission lines are affected by the external environment, the tension of the wires cannot be adjusted, and the transmission lines are prone to collapse when they are stressed for a long time. The phenomenon of disconnection affects the safety and stability of power grid transmission. At the same time, when the existing transmission lines are laid, they cannot effectively insulate the transmission lines. When the voltage of the transmission lines is large, it is easy to cause breakdown of the insulation parts. The phenomenon that the insulating part loses its insulating ability and conducts electricity, which affects the safety of power transmission lines and other problems
