Abstract
The invention relates to an arc welder transformer, in particular to a major component for separation a welder from the power network as well as for power transformation, belonging to a special transformer in the welding industry. The invention is characterized in that, firstly a down-primary sheathed-wire and a secondary sheathed-wire are respectively arranged on the top and the bottom of a central-array; and then an up-primary sheathed-wire is arranged onto the central-array. A fastening screw for fixation is used to inter-cross through the up-primary sheathed-wire, the secondary sheathed-wire and the down-primary sheathed-wire. Afterwards, both a top board and a bottom board of the transformer can be assembled. Finally, the wire tails of each pair of the up-primary sheathed-wire and the down-primary sheathed-wire are connected, as well as the heads of each pair of the up-primary sheathed-wire and the down-primary sheathed-wire are respectively connected to acquire a three-phase input. The lead wire of the secondary sheathed-wire is fixed by an output terminal. The invention has the advantages of strong bearing capacity and high current impulse withstand discharge capacity, avoidance of fever windings due to transformer overload, less liability of loosening of sheathed-wire due to strong fastening force, and good ventilation channel inside the welder due to compact integral structure and high ventilation capacity.
Description
Technical field
The present invention relates to a kind of transformer of arc welder, the main body of welding machine and electrical network isolation specifically and power conversion is one of special transformer in the welding profession.
Background technology
In prior art, transformer of arc welder mainly adopts main transformer device top board and main transformer lower platen to compress up and down by insulated column, fastening screw, plain cushion, bullet pad, nut, but loosening phenomenon is arranged.Secondary employing sub-thread light copper bar upright around, interlayer adopts comb tooth to do at interval, blocks secondary air channel, be unfavorable for secondary heat radiation, when comb tooth has damage, cause secondary short circuited easily, for preventing kelvin effect, the ampacity of single cord unit square sectional area is little, and line directly needs overstriking.Fastening screw is in the middle of the stem and stem of transformer core, because compact conformation blocks the air channel, is unfavorable for that complete machine ventilates.Since secondary make with light copper upright around, cause turn-to-turn short circuit easily; And coiling need special equipment, and adopt full copper coiling, manufacturing cost height.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of transformer of arc welder is provided, bearing capacity is strong, and shock-resistant electric current is big, is difficult for burning the winding phenomenon because of traffic overload; Fastening force is strong, and the line bag is difficult for loosening, and compact overall structure and draught capacity is strong has guaranteed the good ventilation road of whole welding machine inside.
Main solution of the present invention is achieved in that
The present invention comprises mainly that main transformer device top board, elementary line are wrapped, under the secondary wire bag, elementary line bag, feature is to install under the elementary line bag up and down and installation secondary wire bag in central row, elementary line is installed again to be wrapped, with fastening screw from elementary line wrap, secondary wire bag and elementary line bag pass in the middle of down fixing, main transformer device top board and main transformer lower platen are installed again, at last every group of elementary line wrapped with buttock line under the elementary line bag and be connected, every group of elementary line wrap with elementary line bag under head be connected respectively, for the three-phase input, the lead-out wire of secondary wire bag is fixed by lead-out terminal.
Described secondary wire bag adopts four groups of by-pass bags of a core assembly post in parallel in twos, forms two groups of outputs, and other two groups identical.Described silicon steel sheet builds up " mountain " font.
Compared with the prior art the present invention has the following advantages:
The present invention adopts the two groups of the 12 groups of by-pass bags six phase secondary windings that form in parallel, for more high-power special transformer provides new design idea; Secondary use aluminium wire envelope curve flat around, layer insulation is good; Adopt many groups in parallel, bearing capacity is strong, and shock-resistant electric current is big, is difficult for burning the winding phenomenon because of traffic overload; Be fastenedly connected employing and pass in the middle of the line bag, fastening force is strong, and the line bag is difficult for loosening, and compact overall structure and draught capacity is strong has guaranteed the good ventilation road of whole welding machine inside; Adopt the coiling of full aluminium wire envelope curve, greatly reduce production cost; Use common winding equipment, equipment is simple, reduced investment, and instant effect is easy to coiling.

Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
The present invention mainly by main transformer top board 1, elementary line wrap 2, under the insulated column 3, fastening screw 4, plain cushion 5, bullet pad 6, nut 7, insulated tube 8, secondary wire bag 9, insulation spacer 10, double threaded screw 11, central row 12, lead-out terminal 13, silicon steel sheet 14, elementary line bag 15 and main transformer lower platen 16 etc. form.
The present invention mainly folds silicon steel sheet 14 earlier, builds up " mountain " font, and arrangement is neat.Install under the elementary line bag 15 and secondary wire bag 9 up and down in central row 12.Described secondary wire bag 9 adopts four groups of by-pass bags of a core assembly post in parallel in twos, forms two groups of outputs, and other two groups identical.Add insulation spacer 10 between every group, refill elementary line then and wrap 2, after wire wrapping is intact remaining silicon steel sheet 14 is inserted, arrangement is neat.Wrap 2, pass in the middle of 15 under secondary wire bag 9 and the elementary line bag fixingly from elementary line with fastening screw 4, plain cushion 5, bullet pad 6, nut 7, insulated tube 8 again, main transformer top board 1 and main transformer lower platen 16 are installed again.Be connected and fixed wired bag with insulated column 3, fastening screw 4, plain cushion 5, bullet pad 6, nut 7 with main transformer top board 1 and main transformer lower platen 16 earlier when main transformer top board 1 is installed with main transformer lower platen 16 and refill double threaded screw 11, lead-out terminal 13 is connected and fixed with secondary wire bag 9.At last all elementary lines are wrapped 2 and elementary line bag under 15 buttock line link together, every group of elementary line wrap 2 and elementary line bag under 15 head be connected to together, for the three-phase input, the lead-out wire of secondary wire bag 9 is fixing with its welding by lead-out terminal 13, and whole parts connection finishes.
Operation principle: transformer adopting Y/Y connected mode of the present invention, elementary winding input three-phase 380V voltage, produce magnetic field, secondary winding is because the inductance principle produces output voltage, when bringing onto load, with load increase the weight of elementaryly for keeping balance, primary current increases, the special place of this transformer, secondary employing is organized the output in parallel of line bag with the post iron core more.
