Summary of the invention

The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of transformer of inverter type welder of effective, long service life.

The purpose of this utility model can realize by following technical proposal:

The transformer of this inverter type welder, comprise that inside has the square core of cavity and is located at the coil in cavity, the top of described cavity has upper skeleton, the bottom of described cavity has lower skeleton, on described lower skeleton, be fixed with the stitch that two rows be arranged in parallel, it is characterized in that, described coil is formed by the coiling of flat copper band, the top of described coil has two main leads that extend out to upper skeleton, the bottom of described coil has the some secondary lead-out wires that connect one to one with stitch, the outside of described secondary lead-out wire is arranged with insulating sleeve, the outside of described coil is coated with the insulation heat-resistant film of being made by polyimide material.

In this transformer, coil is formed by the coiling of flat copper band, compares with traditional handicraft, has saved 50% copper material, makes the volume of transformer reduce half, and power ascension 30%.Polyimides has stronger high temperature resistant, corrosion-resistant and insulation property, and it can be spent by energy high temperature resistant 260, has effectively extended useful life; And be arranged with insulating sleeve in the outside of secondary lead-out wire, further extend the useful life of transformer.In this transformer, insulating sleeve is the Teflon sleeve pipe.

In the transformer of above-mentioned inverter type welder, wherein described main lead consists of the boiling hot solder of outer field red heat-shrinkable T bush and internal layer, and the described main lead of another root consists of the boiling hot solder of outer field black fever Heat-Shrinkable Tubings and internal layer.

In the transformer of above-mentioned inverter type welder, described magnetic core outer felt is wound with one deck horse traction adhesive tape.

Compared with prior art, the transformer of this inverter type welder has the following advantages:

Coil is formed by the coiling of flat copper band, compares with traditional handicraft, has saved 50% copper material, makes the volume of transformer reduce half, power ascension 30%; The outside of coil is coated with the insulation heat-resistant film of being made by polyimide material, and polyimides has stronger high temperature resistant, corrosion-resistant and insulation property, and it can be spent by energy high temperature resistant 260, has effectively extended useful life; And be arranged with insulating sleeve in the outside of secondary lead-out wire, further extend the useful life of transformer.
