A double-protection connection device with buffer overhead ground wire

Abstract

A double-protection connection device with a buffer overhead ground wire includes a connecting rod, a Fixture, a triangular connection plate, a main load-bearing terminal ring, a main load-bearing wire clamp, a spare connecting guide, a Backup connection pillar and standby wire clip, By setting a spare connecting guide, A standby connection guide post and a standby wire clamp form a standby connection piece, so that the main load-bearing terminal ring or the main load-bearing wire clamp can play a load-bearing connection role after the main load-bearing wire clamp is damaged, At the same time,a cushion spring is arranged between the standby connection guide sleeve and the standby connection guide post, As a result, after the main load-bearing terminal ring or the main load-bearing wire clamp is broken, the spare connector is shifted from being slightly stressed to undertaking all the tensile forces of the overhead wire, and the instantaneous impact force is buffered to protect the spare connector. The invention provides double protection for the overhead ground wire connection and reduces the instantaneous impact force with its own buffer.

Description

technical field [0001] The invention relates to the field of safety of overhead wires, in particular to a double-protection connection device for overhead ground wires with a buffer. Background technique [0002] 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 accident in an important crossing area will cause huge loss of personnel an...

AI Technical Summary

Problems solved by technology

Due to the limitations of the material of the overhead ground wire itself and construction fittings, it is not possible to adopt a crimping process with high reliability like the wire. When other connection methods are adopted, the reliability of the connection of the overhead ground wire will decrease to a certain extent during the operation and maintenance process. Once Disconnection accidents in important crossing areas will cause huge loss of personnel and property, resulting in extremely bad social impact
