Backup-protection confection method and device of transmission overhead ground wire for important crossed region safety

Abstract

The invention discloses a backup-protection confection method and device of a transmission overhead ground wire for important crossed region safety. The technical scheme of the backup-protection confection device of the transmission overhead ground wire for the important crossed region safety is that a main force bearing fixed cable clamp is arranged at the end of an overhead ground wire, and hinged to a transmission pole tower fixed plate through a U-shaped hanging ring and a connecting bolt, furthermore, a backup protection device is arranged on the overhead ground wire close to a transmission pole tower, and comprises a backup fixed cable clamp and an extension rod, wherein the backup fixed cable clamp is fastened together with the overhead ground wire, in addition, the backup fixed cable clamp is hinged to one end of a connecting plate, the other end of the connecting plate is hinged to one end of the extension rod, and the other end of the extension rod is connected with the transmission pole tower fixed plate through a connector to form dual-protection connection. By adopting the backup-protection confection device of the transmission overhead ground wire for the important crossed region safety disclosed by the invention, faults and the fault-trip times of a transmission line are effectively lowered, the outage time of a power grid is reduced, and the power supply quality of the power grid and the customer satisfaction are improved.

Description

[0001] Technical field: [0002] The invention relates to a method for safe crossing of overhead wires, in particular to a method and device for safe backup and connection of important crossing areas of power transmission overhead ground wires. [0003] Background technique: [0004] With the rapid development of power grid scale and drastic changes in the social environment, the operation and maintenance management of high-voltage transmission lines presents the characteristics of diversification and complexity. Across important areas such as railways, highways, private houses, schools, etc. At the same time, in order to meet the requirements of lightning protection and carrier communication, transmission lines need to erect overhead ground wires above the conductors. Due to the limitations of the material of the overhead ground wire itself and the construction fittings, it is not possible to adopt a crimping process with high reliability like the wire. A disconnection accide...
