Description
Technical field
The invention belongs to inversion welding technology field, it is specifically related to a kind of inversion being used in inversion welding source and becomes
Depressor.
Background technology
Current existing use IGBT inversions pulse MIC (Metal Inert-Gas Welding consumable electrode noble gas protectives
Weldering) welding machine electric power is that its transformer frequencies is typically 20KHz, in pulse MIC welding termination process using fixed reverse frequency
In, it is necessary to high to power pulse control progress, particularly to meet pulse peak current size, time, raising speed on pulse current
The demands such as degree, decrease speed and arc length length control.
Frequency can also reach process requirements for the source of welding current of 20K in low current segment control, when needing high current to weld,
Due to frequency limited, its arc length is also difficult to control to, and it is fast welding wire melting rate occur, welding base metal and unfused phenomenon, electric arc
Arc length is unstable, it may appear that jackscrew or current interruption phenomenon, it is difficult to meet welding demand, therefore, our inventions both can be in 20KHz
Regulate and control the source of welding current of welding current voltage characteristic to 80KHz different frequency sections, in different duty requirements using corresponding
Reverse frequency, meet process requirements, general its contravariant transformer of inverter can only be used under fixed frequency, overclocking
When occur burning power device the problems such as, therefore the application for solve this problem propose solution.
The content of the invention
It is an object of the invention to provide a kind of contravariant transformer, it is adaptable in the regulation and control of 20KHz to 80KHz different frequency sections
In the source of welding current of welding current voltage characteristic, with simple structure working stability.
The present invention is achieved by the following technical solutions.
A kind of contravariant transformer, including coil bag, several magnetic cores and pressing plate side by side are provided, the coil is wrapped in several
On magnetic core side by side, coil bag by primary coil and secondary coil coiling, coil bag be provided with two primary input terminals, two
Secondary outlet terminal and a centre tap terminals；The pressing plate is arranged on the upper and lower sides of magnetic core, with tension between pressing plate
Screw rod is connected.
Further, the magnetic core uses UR56 type magnetic cores, several magnetic cores to be installed in parallel side by side, and stretching screw is from magnetic core
Between pass through, magnetic core and coil bag are fixed.The pressing plate is epoxy resin board of the thickness in 10-15mm.
Contravariant transformer of the present utility model is applicable to 20KHz to 80KHz different frequencies, and burning power occurs during overclocking
Device；With simple structure working stability；Its power pulse control progress is high, meets pulse peak current size, time, pulse
The control of the electric current rate of climb, decrease speed and arc length length.
Brief description of the drawings
Fig. 1 is the overall structure view of the contravariant transformer in embodiment.
Fig. 2 is the topology view of contravariant transformer in embodiment after coil bag is removed.
Fig. 3 is the concept view of the contravariant transformer in embodiment.
Specific embodiment
Technical scheme is described in further detail with specific embodiment below in conjunction with accompanying drawing, makes this area
Technical staff can understand complete understanding inventive nature of the invention.
Shown in reference picture 1, Fig. 2 Fig. 3, the present embodiment is a kind of contravariant transformer, including coil bag, several magnetic cores side by side
And pressing plate, magnetic core using 3 groups of UR56 magnetic cores it is used in parallel, the inverter that contravariant transformer can be in the range of 20KHz to 80KHz
On use.
Transformer device structure is as shown in FIG.：1 and 2 is two primary input terminals of contravariant transformer；3 and 5 is two
Secondary outlet terminal, 4 is secondary centre tap terminals；
Using UR56 magnetic cores, material is MN-ENFerrite Material, 3 groups of magnetic cores are installed in parallel use side by side, between magnetic core
Gap is 0.1-0.3mm；Pressing plate is two pieces, is separately positioned on the upper and lower sides of magnetic core, is connected with stretching screw between pressing plate, and
Stretching screw passes through from the middle of magnetic core, and every group of magnetic core and coil bag are fixed, and pressing plate uses thickness 10-15mm's
Epoxy resin board.
By primary coil and secondary coil coiling, coil bag is provided with two primary input terminals, two secondary to coil bag
Outlet terminal and a centre tap terminals；The level of coil bag can be divided into from the inside to surface coil rack, primary coil with
The insulating barrier between insulating barrier, secondary and magnetic core between insulating barrier, primary coil layer, primary and secondary between magnetic core.
Coil wrapping method is that, first around primary coil, primary coil uses the cathode copper enamel-cover flat copper of a plurality of 0.3*2mm
Line and around, and will closely and around；Further around the exhausted gorgeous layer between primary secondary, it is 0.05 to 0.1 that insulating materials uses thickness
㎜ mylars, using multilayer and around；Secondary coil uses the multiply enamel-covered wire of single diameter 0.1mm and around secondary coil is total
Line footpath area reaches more than 90 square millimeters.
