Problems solved by technology

[0004] In the initial factory production and processing process, due to various unavoidable reasons, there will be some short cables that are not long enough for delivery. Over time, the backlog of these short cables will directly increase the production cost of the manufacturing enterprise and cause waste.

Embodiment Construction

[0028] A method for connecting railway through ground wire, step 1: preparatory work (as attached figure 2 shown)

[0029] 1) Remove about 20mm of the sheath 3 at the ends of the two through-ground wires that need to be connected;

[0030] 2) Prepare the porcelain sleeve 4 for welding and connecting the pure copper conductor 2 (magnetic tube butt welding machine);

[0031] 3) Prepare the open brass sleeve 5, the opening size is slightly larger than the diameter of the cable core 1, and the maximum width of the brass sleeve 5 when unfolded is slightly smaller than the outer diameter of the sheath, leaving enough welding allowance;

[0032] 4) Prepare the electrode clamping mold 6 of the magnetic tube butt welding machine;

[0033] 5) Prepare the handheld argon arc welding machine 7.

[0034] Step 2: Welding connection of the cable core (as attached image 3 shown)

[0035] 1) Put the porcelain sleeve 4 on the cable core 1 from which the sheath 3 has been removed, clamp th...

Abstract

The invention discloses a connection method for railway through-earth wires. The porcelain sleeve is placed on the cable core from which the sheath has been removed, and the cable core is welded by a butt welding machine; after welding, the porcelain sleeve is smashed; the cable core is welded Grind the joint part; cut off the brass sleeve of appropriate length, put on the brass sleeve; use a vise, clamp the brass sleeve, and tightly fit it on the cable core; line the brass sleeve and the circumference of both ends Weld with the sheath; grind the welding scars of the brass casing. Beneficial effects of the present invention: different welding methods for the cable core and the sheath are used for welding recovery, which can not only ensure the reliability of the use of the spliced ​​cable, make it maintain good grounding conductivity and corrosion resistance, but also digest the short section cable.

Description

technical field [0001] The invention relates to the field of railway electrical facilities, in particular to a welding equipment and a specific process method for connecting railway through ground wires. Background technique [0002] The railway through-ground wire is the main grounding component and cable product of the comprehensive grounding system of the high-speed railway. The main structure of the railway through the ground line (as attached figure 1 Shown): The cable core 1 is a plurality of pure copper conductors 2 twisted together in the way of layer twisting or concentric twisting. The outer part of the cable core 1 is provided with a layer of sheath 3, and the material of the sheath 3 is brass alloy. [0003] After the railway penetrating ground wire is buried underground, the brass alloy sheath 3 can not only ensure that the penetrating ground wire has good conductive grounding performance, but also prevent the soil environment from corroding the pure copper co...
