Description

Technical Field

[0001] The invention belongs to the technical field of power transmission line maintenance tools, and in particular relates to an overhead power transmission line anti-vibration hammer resetting device and method. Background Art

[0002] Overhead lines are transmission lines erected above the ground, with insulators used to fix the transmission wires on towers erected on the ground to transmit electricity. The wires are used to conduct current and transmit electricity. Lightning conductors, also known as overhead ground wires, are used to reduce the chance of lightning striking the wires and improve lightning resistance. Towers support the wires and lightning conductors and maintain a safe distance. Insulators insulate the wires from the ground to ensure that the lines have reliable electrical insulation strength. Hardware is used to support, fix and connect wires and insulators. Overhead lines are easily affected by weather and environment such as strong winds, lightning strikes, dirt, ice and snow, and can be divided into three types according to voltage levels: low voltage, high voltage and ultra-high voltage. Overhead line vibration refers to the vibration phenomenon caused by natural factors such as wind, ice and snow. The high-frequency, low-amplitude vertical vibration caused by breeze has a high frequency and a small amplitude. Breeze vibration may cause fatigue breakage of overhead lines, wear of hardware and damage to tower components. The anti-vibration hammer is a protective hardware installed on overhead lines to reduce the vibration of conductors caused by wind. During long-term use, the anti-vibration hammer will shift in position due to its own weight and vibration, affecting its anti-vibration effect on the overhead lines. Therefore, it is necessary to provide an anti-vibration hammer resetting device and method for overhead transmission lines. Summary of the invention
