A kind of fast live wire clip

Abstract

The invention discloses a fast live-connecting wire clip, comprising: a wire clip main body, which includes a connecting section, a hook head located at the upper end of the connecting section, and a housing shell located at the lower end of the connecting section, and the inside of the connecting section There is a slideway; an extrusion assembly, one end of which is slidably connected in the slideway; a drive assembly, which includes a screw passing through the housing, and the upper end of the screw is rotatably connected to the lower end of the extrusion assembly; and , a locking assembly, which includes a folding lever hinged in the housing and a compression spring fixed in the housing; the folding lever includes a pressing bar and a toggle bar that engage with each other, and the inner side of the pressing bar A thread fit for the thread opening of the external thread of the screw rod is provided. The invention can greatly reduce the operational difficulty of fastening the insulating rod to the live wire clamp, thereby reducing the time and risk of operation, and meanwhile, the invention can also ensure the close contact between the wire clamp and the main conductor to prevent detachment.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a fast live wire clamp. Background technique [0002] With the rapid development of the power grid and the continuous improvement of the requirements for power supply reliability in various industries, live work has become an important means of construction and maintenance to effectively reduce user outage time, improve customer service quality, and improve the economic benefits of the power grid. One of the important live-work projects is liveline work (connecting and fixing the drain wire to be externally connected to the main wire of the power grid through a clamp to realize the power-taking process of the drain wire). The work of live-fired distribution network can be carried out by using ground potential insulating rod method, intermediate potential insulating rod, and insulating gloves. Currently, there are many live-fired methods and clamps, among which ...

AI Technical Summary

Problems solved by technology

[0003] The line clamp needs to be installed on site with the insulating rod, but the currently used live loading and unloading line clamp has the following disadvantages: when installing the line clamp, it is fixed on the main line by rotating the bolt at the end of the insulating rod, but because the operating object is 10KV It is very difficult to operate the live fire operation. If the bolt is rotated only by the insulating rod, the connecting part of the insulating rod will slide, making it difficult to exert the rotating torque, resulting in the main wire and the clamp not being in close contact, making it difficult for the clamp to connect with the main wire. The problem of close contact, and it takes a long time; at the same time, when using the insulating rod to twist and tighten, do not use a lot of force, otherwise the connecting parts of several insulating rods will be twisted.
