Freely-rotating bottom-opened single-groove clamping block type connection crimping device

Abstract

The invention relates to a freely-rotating bottom-opened single-groove clamping block type connection crimping device. Because a second single-groove clamping block is arranged at an opposite positionof one side of a first single-groove clamping block, the first single-groove clamping block and the second single-groove clamping block can clamp a trunk conductor at a T connection point when a branch conductor and a trunk line are connected. Because a first pressure bolt screw hole is formed in the lower middle part of the first single-groove clamping block and a second pressure bolt screw holeis formed in the lower middle part of the second single-groove clamping block, a pressure bolt can be screwed firmly into the first pressure bolt screw hole in the lower middle part of the first single-groove clamping block and the second pressure bolt screw hole in the lower middle part of the second single-groove clamping block after the first single-groove clamping block and the second single-groove clamping block clamp the trunk conductor at the T connection point.

Description

technical field [0001] The invention relates to a splicing connection fitting on a transmission and distribution line, directly relates to a free-rotating bottom-opening single-groove clip-type splicing crimping device, and is especially suitable for use on an upgraded high-voltage transmission and distribution line. Background technique [0002] The transmission of electricity to users is done through high-voltage transmission and distribution lines. In the construction of high-voltage transmission line engineering, branch lines are often connected on high-voltage trunk lines. The method of continuous connection between the branch line and the high-voltage main line is as follows: the T-junction of the high-voltage main line and the lead end of the branch line are realized by crimping the two existing parallel groove clamps. The disadvantages of the parallel channel clamp on the T contact of the high-voltage main line are: 1. The crimping and the load branch line on the T ...

AI Technical Summary

Problems solved by technology

The disadvantages of the parallel channel clamp on the T contact of the high-voltage main line are: 1. The crimping and the load branch line on the T contact of the high-voltage main line and the parallel channel clamp cannot be safely and conveniently separated under the normal and stable power supply state of the main line electrified trunk line

2. It is not possible to maintain or replace the equipment and appliances at the rear end of the branch line that has failed when the main line is not switched on and the power supply is uninterrupted.

When it is necessary to use a live work vehicle to implement live work, the technical problem that is not solved by people is that the live work vehicle is limited to the places where the work vehicle can enter, but it is not available for the work vehicle. It is not possible when the field must be operated
