Abstract

The utility model provides a step up transformer for the arc generating of an argon welder; the scheme mainly comprises a magnet ring and a bank cable; the scheme is characterized in that both ends of the bank cable are respectively provided with connection points Z1 and Z2; the bank cable arranged between the two connection points Z1 and Z2 is sheathed with 2-5 groups of magnet rings; one winding thin connecting wire is wound on each group of magnet rings, and the start end of each winding connecting wire is connected; the end of each winding connecting wire is connected as the primary coil of a transformer, and the bank cable is the secondary coil of the transformer. Each group of magnet rings is provided with the same magnet rings of 2-5, and is sheathed on the bank cable.

Description

A kind of argon arc welding machine striking step-up transformer

Affiliated technical field:

The utility model relates to a kind of transformer, especially a kind of argon arc welding machine striking step-up transformer.

Background technology:

In the prior art, technique known is exactly the step-up transformer of using on argon arc welding machine at present, it is on one group of big magnet ring, on magnet ring, twine four circles with a bigger multicore cable of cross section, secondary coil as transformer is connected in the welding machine electric power major loop, on magnet ring, twine a circle with a thin wire, be connected on the radio-frequency generator as the primary coil of transformer, constitute one at the beginning of, inferior ratio is 1: 4 step-up transformer.This structure, because the multicore cable diameter is bigger, the technology of twining on magnet ring is difficulty relatively, be not suitable for producing in enormous quantities, it is very high to add turn-to-turn voltage, and turn-to-turn insulation is very easily destroyed, the difficulty of insulation is high and be difficult for grasp, and this is an existing in prior technology subject matter.

Summary of the invention:

The utility model is at the existing in prior technology deficiency, and provide a kind of argon arc welding machine striking step-up transformer technical scheme, this scheme is bigger at diameter, as suit bead group on the multicore cable of transformer secondary output, every group of magnet ring twines a circle primary coil again, forms a step-up transformer equally, the difficulty of having avoided large diameter multicore cable to twine and insulate on magnet ring, make simple for processly, be fit to produce in enormous quantities.

This programme is realized by following technical measures: mainly include magnet ring and multicore cable, the characteristics of this programme are at the two ends of described multicore cable a contact Z1 and Z2 to be arranged respectively, on the multicore cable between two contact Z1, the Z2, be set with 2-5 group magnet ring, on every group of magnet ring, also be wound with a circle thin wire simultaneously, and the origin or beginning of each circle thin wire connected, the end of each circle thin wire is connected primary coil as transformer, and described multicore cable is the secondary coil of transformer.The concrete characteristics of this programme also have, and the magnet ring of respectively organizing of suit is every group 2-5 identical magnet ring arranged on the described multicore cable.

The beneficial effect of this programme can be learnt according to the narration to such scheme, since in this scheme major diameter as the multicore cable of transformer secondary output coil on several groups of bead groups of suit, every group of magnet ring twines the primary coil of a circle thin wire as transformer again, step-up transformer of this same formation, but the technology difficulty of having avoided the major diameter multicore cable on magnet ring, to twine, also solved the not wield difficulty of turn-to-turn insulation, make processing technology become easily simple, satisfied the adaptation requirement of mass production.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Description of drawings:

Fig. 1 is the part sectional structure schematic diagram of the utility model embodiment.

Fig. 2 is the substitutional connection schematic diagram of Fig. 1.

1 is the thin wire of primary coil among the figure, and 2 is the multicore cable of secondary coil, and 3 is magnet ring.

Embodiment:

For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by an embodiment.

By accompanying drawing 1 as can be seen, the argon arc welding machine striking step-up transformer of this programme, mainly be a contact Z1 and Z2 respectively to be housed at a multicore cable (2) two ends as the transformer secondary output coil, at two contact Z1, on the multicore cable between the Z2 (2), be set with 2-5 group magnet ring (3) by one group of 2-5 identical magnet ring (3) formation, this embodiment is to be made of four groups of magnet rings (3) of one group four identical magnet rings (3), on every group of magnet ring (3), also be wound with circle list core thin wire (a 1) a1a2 simultaneously, b1b2, c1c2 and d1d2, and with the origin or beginning a1 of each circle thin wire (1), b1, c1 is connected with d1, with the terminal a2 of each circle thin wire (1), b2, c2 is connected the primary coil as transformer with d2.This has just formed four transformers a common secondary coil, the primary coil of four transformers is homophase, the same number of turn, import same high-frequency signal, so each transformer is all responded to identical induced signal is arranged on secondary coil, the signal that four transformers are responded on same secondary coil will produce stack, and this just is equivalent to a high-frequency step-up transformer of 1: 4.The equivalent diagram of this step-up transformer on circuit is just as Fig. 2.

Claims

1. argon arc welding machine striking step-up transformer, mainly include magnet ring and multicore cable, it is characterized in that: a contact Z1 and Z2 are respectively arranged at the two ends of described multicore cable, on the multicore cable between two contact Z1, the Z2, be set with 2-5 group magnet ring, on every group of magnet ring, also be wound with a circle thin wire simultaneously, and the origin or beginning of each circle thin wire connected, the end of each circle thin wire is connected primary coil as transformer, described multicore cable is the secondary coil of transformer.

2. argon arc welding machine striking step-up transformer according to claim 1 is characterized in that: on the described multicore cable suit respectively organize magnet ring, every group has 2-5 identical magnet ring.
