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 metal sheath, leaving enough welding margin;

[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...

Abstract

The invention discloses a method for connecting a railway through ground wire. The method comprises the following steps of sleeving a porcelain sleeve on a cable core of which a sheath is removed, andwelding the cable core by using a butt welding machine; after welding, smashing the porcelain sleeve; polishing the welding joint part of the cable core; cutting out a brass sleeve with a proper length, and sleeving the brass sleeve; clamping the brass sleeve by using a bench clamp, and tightly sleeving the brass sleeve on the cable core; welding the straight joint of the brass sleeve and the joint of the circumferences at the two ends and the sheath; and polishing a crater of the welding part of the brass sleeve. The method has the beneficial effects that different welding modes of the cablecore and the sheath are respectively used for welding recovery, so that the use reliability of the continuous cable can be ensured, good grounding conductivity and corrosion resistance can be kept, and the short-section cable can be digested.

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...
