Description

A kind of pair of reactor

Technical field

The utility model relates to welding machine electric power, especially the reactor in the welding machine electric power.

Background technology

The effect of reactor in the source of welding current is very important, generally includes several sections such as iron core, coil, reactor support.And use the reactor in the source of welding current to be single reactor at present.As being that 2003.4.24 discloses a kind of supply unit that is used on the electric welding machine in the patent document on November 5th, 2003 at publication number for the CN1453927A applying date, comprise rectifier and filter inductance, both work together the commercial AC supply voltage are converted to dc voltage these.This dc voltage is converted to the AC voltage of high frequency by inverter, and this high-frequency AC voltage is carried out voltage transformation by voltage transformer subsequently.High-frequency AC voltage through voltage transformation is converted to dc voltage by rectifier diode and filter reactor, and the dc voltage of generation is added to workpiece and welding torch.High-frequency AC voltage by rectifier diode after output DC pulse voltage, the DC pulse voltage of output outputs to the welding machine outside through after single reactor filtering again, for outside use.Weld or cut.The supply unit reactor inductance amount of this structure is little, and filter effect is bad, and the dc voltage of output is flat inadequately, strand wave system number is big, can not satisfy practical requirement,, need to increase inductance value in order to satisfy practical requirement, as increasing inductance value, the iron core that will extend increases coil turn, and the length of reactor is elongated simultaneously, structural design and its installation are made troubles, and manufacturing cost has raise.

The utility model content

The purpose of this utility model is for a kind of pair of reactor is provided, and its inductance value is big, and magnetic flux is difficult for saturated, can improve the welding or the cutting technique of welding machine.

For achieving the above object, a kind of pair of reactor comprises first reactor and second reactor, first reactor comprises first coil and first iron core, first iron core is located in first coil, and second reactor comprises second coil and second iron core, and second iron core is located in second coil; Described first coil and second coil are connected in series; The bottom of described first coil and second coil is provided with the reactor support; Be welded with the reactor connector between first iron core and second iron core.

Said structure, owing to comprised two reactors, and first coil and second coil be connected in series, and compared with prior art, increases in the same terms small inductor amount, magnetic flux is not easy saturated, therefore, can improve the welding and the cutting technique of welding machine.

As improvement, the junction of described first coil and second coil is arranged with heat-shrink tube.This structure has played insulating effect.

As improvement, be provided with insulation board between described first coil, second coil bottom and the reactor support.The good insulation preformance of reactor like this, the security performance height.

As improvement, be provided with the first bakelite bar between described first iron core and first coil, be provided with the second bakelite bar between second iron core and second coil.

Description of drawings

Fig. 2 is a front view of the present utility model;

Fig. 3 is the two use circuit diagrams of reactor in welding.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.

Two reactors as depicted in figs. 1 and 2, comprise first reactor 1 and second reactor 2, first reactor 1 comprises on first coil 11 and first iron core, 12, the first iron cores 12 the first bakelite bar is installed that first iron core 12 and the first bakelite bar are inserted in first coil 11; Second reactor 2 comprises on second coil 21 and second iron core, 22, the second iron cores 22 the second bakelite bar is installed that second iron core 22 and the second bakelite bar are inserted in second coil 21; First coil 11 and second coil 21 are connected in series, and are with heat-shrink tube 3 in the junction, make connector play insulating effect; Bottom at first coil 11 and second coil 12 is equipped with reactor support 4; Be welded with reactor connector 5 between first iron core 12 and second iron core 22.Be provided with insulation board 6 between first coil, second coil bottom and reactor support 4, like this, the insulation property of reactor support 4 are better, use safety.

Two reactors can directly be contained on the base plate of welding machine in use, also can be installed on other the position.As shown in Figure 3, an end of two reactors is connected on the negative pole of welding machine rectification output, and the other end is connected on the lead-out terminal of welding machine.At first, the electric current of main transformer output is through the rectification circuit rectification, and secondly, by two reactors, two reactors play the effect of filtering.Owing to comprised two reactors, and first coil and second coil be connected in series, and compared with prior art, increases in the same terms small inductor amount, and magnetic flux is not easy saturated, therefore, can improve the welding and the cutting technique of welding machine.

In sum, the two reactors of the utility model are when implementing, and its inductance value is big, and magnetic flux is difficult for saturated, can improve the welding or the cutting technique of welding machine.

Only, the above person is preferred embodiment of the present utility model only, is not in order to limit the scope that the utility model is implemented; So done equivalence or variation person easily when haveing the knack of this skill, as mentioned above, change and modification not breaking away from the equalization of being done under spirit of the present utility model and the scope, all should be covered by in the claim of the present utility model, close first Chen Ming.
