Method for carrying out 10kV charged wire connecting operation by CO2 laser cable peeling device

Abstract

The invention relates to a method for carrying out 10kV charged wire connecting operation by a CO2 laser cable peeling device. The CO2 laser cable peeling device is suspended on a live wire; H-shaped notches are cut out at two sides of the live wire respectively; the H-shaped notches at two sides are accurately butted and then form two annular notches at two sides and two coherent longitudinal notches between the two annular notches on the live wire; a cut insulating sheath is peeled off from the live wire; one end of a drainage wire is locked by a lock bar; the drainage wire is sent to a live wire connection position; a round mouth screw type drainage wire clamp is suspended on the live wire with a drainage wire clamp operating rod; a bolt is tightened; and the drainage wire clamp and the wire are tightly fixed. Online peeling is carried out on the live wire by the CO2 laser cable peeling device; a metal cable core is not damaged; the peeling efficiency is high; the notches are accurate; and the reliability of 10kV charged wire connection is greatly improved.

Description

technical field [0001] The invention relates to an operation method for live work, in particular to a method using CO 2 Laser cable peeling device for 10kV live wire connection operation method. Background technique [0002] Power supply is the basic guarantee for maintaining social production and residents' life, and is an important pillar of national economic development. However, with the rapid development of the national economy and the continuous improvement of people's living standards, the power grid system has gradually become larger, and the expansion of the power grid has become more frequent, requiring frequent maintenance, new equipment installation, power connection and other construction in large quantities. As far as the 10kV power supply line is concerned, due to the long power supply line and the increase in power supply users, a power outage will cause immeasurable losses, especially in residential areas with dense high-rise buildings, the power outage inf...

AI Technical Summary

Problems solved by technology

[0004] The domestic 10kV power supply line live connection operation is a routine high-voltage live operation. It has gone through four technical stages: insulating gloves, insulating tools, insulating bucket trucks and robots. The first three stages are all manual live work. In the threat of electric field, the risk factor is high, which is likely to cause personal injury and death accidents. However, the live connection operation of the robot has no stress feeling when operating the lead wire cutting insulation skin tool, and the mechanical tool often scratches the metal cable core, so it cannot be widely used.

[0005] There is also a technical form of insulation piercing lead clip, which is also a direction for the development of live connection technology at present, but the puncture contact piece is limited by the material, and in the high voltage level live connection operation, it is difficult to face the insulation protection layer of high voltage cables. The density and thickness of the puncture contact piece and the contact area of ​​the cable metal core are not easy to control, and it is very easy to cause current overload and heat due to poor contact, and even fire accidents
