Description
Technical field
The utility model is related to electronic technology field, more particularly to a kind of source of welding current.
Background technology
There is Kelvin effect in alternating current, when electric current passes through cable core conductor, concentrate on the thin layer of conductor appearance when in use, more
Close to conductive surface, current density is bigger, therefore adds current loss, resistance.
The source of welding current is different from general power supply, in welding, it is necessary to which very big electric current produces heat, so as to melt gold
Category.Therefore, the electric wire used in the source of welding current is just more prone to because Kelvin effect produces bigger current loss and resistance.
Utility model content
The purpose of this utility model is to provide a kind of source of welding current using the skin coiling that becomes, at least one above-mentioned skill of solution
Art problem.
The technical problem that the utility model is solved can be realized using following technical scheme：
Using the source of welding current for the skin coiling that becomes, including a transformer, the transformer includes an iron core, the iron core surface
It is wound with copper conductor,
Characterized in that, the copper conductor is a hollow copper conductor；
One end of the hollow copper conductor is provided with an air inlet, and the other end of the hollow copper conductor is provided with a gas outlet；
Also include a cooling system, the air inlet of the cooling system connects the gas outlet of the hollow copper conductor, described
The air outlet of cooling system connects the air inlet of the hollow copper conductor；
The copper conductor outer wall is provided with least two strip grooves, the length direction of the strip groove and the hollow copper
The length direction of wire is identical.
Hollow copper conductor can effectively reduce Kelvin effect, and the groove for being arranged on outer wall adds the surface of hollow copper conductor
Product, can pass through more electric currents so that the source of welding current in welding with bigger current strength, and then improve welding
The welding performance of power supply.
Further, since hollow copper conductor has gathered bigger electric current, hollow copper conductor is set to be constantly in the state of high temperature, this
An air-cooled internal circulation system is formed between cooling system and hollow copper conductor that patent is provided with, hollow copper conductor is effectively reduced
Temperature, improves the electric conductivity of hollow copper conductor, increases its security and service life.
The distance between two cell walls of the strip groove are gradually reduced from notch to bottom land.More internally, electric current
Gather fewer, therefore, it is more a little bit smaller that the space of bottom portion of groove can be designed.
The hollow copper conductor inwall is provided with least two grooves, the length direction of the groove and the hollow copper conductor
Length direction it is identical.Increase the contact area of hollow copper conductor and air, improve heat dispersion.
The strip groove has four, and four strip grooves are evenly distributed on the outer wall of the hollow copper conductor；
The groove has four, and four grooves are evenly distributed on the inwall of the hollow copper conductor；
The strip groove is interspersed with the groove.Copper conductor is avoided to deform or even be broken.
The A/F of the A/F of the strip groove and the groove is respectively less than 1mm.Generation hollow copper is avoided to lead
The fracture of line.
The depth of the strip groove and the depth of the groove are respectively less than 1/3rd of the hollow copper conductor thickness.
Hollow copper conductor is avoided to be broken.
Brief description of the drawings
Fig. 1 is the radial cutaway view of the utility model hollow copper conductor.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face, which combines to be specifically illustrating, is expanded on further the utility model.
Reference picture 1, using the source of welding current for the skin coiling that becomes, including a transformer, transformer includes an iron core, iron core surface
Copper conductor is wound with, copper conductor is a hollow copper conductor 1；One end of hollow copper conductor 1 is provided with an air inlet, hollow copper conductor 1
