Description
Technical field
The present invention relates to transformer manufacture technology, relate in particular to the Welding technology of electromagnetic wire in the power transformer winding winding process.
Background technology
Need welding lead in the winded coil of transformer process, there are a lot of problems in present wire welding process.Generally, the welding between solid conductor is all to use current lifting device and soldering turret, or overlap welding, or the oblique weldering; Use gas welding between transposed conductor and composite conductor, need to shift oxygen and acetylene cylinder onto scene during the gas welding welding, and the maintenance certain distance, before welding, need naked light to light welding gun, naked light is processed solder joint, very large potential safety hazard is arranged like this, and when welding need a large amount of asbestos cords, weld in the cleaning shop, can produce a large amount of steam and other gases in welding process, this purification room to constant temperature and humidity is very unfavorable.All more or less there is following problems in these welding methods: because solder joint causes that greatly coil is radial, axially overproof, pull-off force because of the large reduction wire of bond pad locations heat affected zone, pollute coil greatly because welding rear polishing workload, environment in removing pollutant workshop etc. during welding.
Summary of the invention
For addressing the above problem, the present invention a kind of Welding technology of electromagnetic wire of transformer that adopts the docking welding manner is provided.
The technical solution used in the present invention is as follows: a kind of Welding technology of electromagnetic wire of transformer comprises the steps:
(1), cleaning in early stage: the insulating barrier that divests the electromagnetic wire welding position;
(2), prune: prune two electromagnetic wires that will dock with the hydraulic pressure wire nipper, the section configuration of two electromagnetic wires is matched, the shape of section is selected according to the type of the electromagnetic wire that specifically will weld;
(3), location: with two electromagnetic wires of electromagnetic wire positioning tool clamping, with two electromagnetic wire docking, adjust the alignment of positioning straight to two section; Positioning tool can come specific design according to type, the size of electromagnetic wire, is used for fixing electromagnetic wire and capable of regulating electromagnetic wire to the elasticity of the face of weld.
(4), welding: with intermediate-frequency welding machine welding two electromagnetic wire interfaces; Replace original soldering turret welding or gas welding mode with the intermediate-frequency welding machine welding, welding quality is high, and the postwelding solder joint is little, and polishing cleaning work amount is little, has greatly reduced the pollution to cleaning shop and coil.
(5), post-processed: polishing solder joint, wrapping insulation.
To the welding of concrete electromagnetic wire the time, section configuration there is certain requirement, be illustrated below in conjunction with the welding process of two kinds of electromagnetic wires commonly used:
During the welding solid conductor, two wire terminations are had one's hair trimmed and the alignment of two sections, place weld tabs between two pairs of faces of weld, clamp welding.Adjust wire to the elasticity of the face of weld by adjusting the electromagnetic wire positioning tool, uses silver-colored phosphorus weld tabs, and weld tabs is trimmed to consistent with the wire section configuration, but its size is bigger, and namely four limit sizes are all grown 1～1.5mm than wire section corresponding sides size.Two ready weld tabs are positioned between two parties between the face of weld, naturally clamp, utilize intermediate-frequency welding machine to weld.The induction coil of intermediate-frequency welding machine used is hand-held induction coil, handled easily.
When welding composite conductor and transposed conductor, had one's hair trimmed in the end of composite conductor, the transposed conductor end is cut into U-shaped, and the length of transposed conductor U-shaped recess is consistent with the end face width of composite conductor, in the opening with insertion transposed conductor U-shaped end, composite conductor end during the location.Also the end of composite conductor can be cut into U-shaped, the transposed conductor end is cut into E shape, and the opening of composite conductor and side wall dimensions and transposed conductor correspondence position match, and during the location, the U-shaped end of composite conductor is inserted in the E shape end of transposed conductor.Two kinds of trim modes need that all wire is carried out depainting processing relief transposed conductor and encase composite conductor, and position with the electromagnetic wire positioning tool, weld with intermediate-frequency welding machine.The induction coil of described intermediate-frequency welding machine is the U-shaped induction coil.Weld with intermediate-frequency welding machine at this, replace original gas welding mode, the welding process non smoke, speed of welding is fast, and soldering tip is little.
The present invention adopts intermediate-frequency welding machine welding electromagnetic wire, prune solder side according to the electromagnetic wire type before welding, welding quality is high, the postwelding solder joint is little, polishing cleaning work amount is little, greatly reduced the pollution to cleaning shop and coil, the office that has reduced product puts, and has improved the quality of transformer and operator's operating efficiency.
