Abstract

The utility model discloses a novel transformer structure, which comprises a secondary coil (1), U-type iron cores (2), insulation boards (3), aluminum sheets (4), anchor ears (5), primary coils (6) and a metal pin (7), wherein every three of U-type iron cores (2) are arranged into a row, and four rows form a whole body; the upper surface, the lower surface, the front surface and the rear surfaceare covered with the aluminum sheets (4); the anchor ears (5) tighten the aluminum sheets (4) and the U-type iron cores (2) together; the two rows of U-type iron cores (2) in the middle integrally serve as a magnetic core; the primary coils (6) and the secondary coil (1) are enwound at the periphery of the magnetic core; and a gap inside the transformer is filled with epoxy resin. The transformerhas the advantages of small impedance, low electromagnetic eddy loss, good insulating property, high force output and long service life, and can suit various environment.

Description

The novel transformer structure

Technical field

The utility model relates to a kind of transformer device structure, particularly relates to the various environment of a kind of adaptation, and impedance is little, and the electromagnetic eddy loss is low, good insulation preformance, the height of exerting oneself, the novel transformer structure of long service life.

Background technology

Now the transformer of a lot of producers is also with the energy consumption E type transformer less than high output, and traditional transformer is relatively poor to the adaptive faculty of environment, the easy bursting by freezing of cold weather, the too high easy damage loom of temperature.Traditional transformer insulated poor-performing, and hot easily when work, keep this high temperature for a long time, not only influence the stability of its work, and also can reduce its useful life greatly.

The utility model content

At above-mentioned the deficiencies in the prior art part, the utility model provides a kind of novel transformer structure, can address the above problem fully.

The technical solution adopted in the utility model is: a kind of novel transformer structure, comprise secondary coil, U sections core, insulation board, aluminium skin, anchor ear, primary coil and metal pins, three U sections cores are arranged in a row, totally four rows form an integral body, front-back covers the layer of aluminum skin up and down, and anchor ear tightens together aluminium skin and U sections core, and middle two row U sections core integral body are as magnetic core, primary coil and secondary coil are wrapped in around it, and epoxy resin is poured at place, the inner slit of transformer.Totally eight layers of primary coils, every layer top and bottom are provided with insulation board.Secondary coil is that a cross section is foursquare rectangular, and its sectional dimension is 20mm * 20mm, and it is arranged on the middle of primary coil.Secondary coil and metal pins are integrally formed, and metal pins is " L " type, which is provided with the limbers of four diameter 8mm.

Advantage of the present utility model is: have the transformer of this new structure, impedance is little, and the electromagnetic eddy loss is low, good insulation preformance, and the height of exerting oneself can adapt to various environment and long service life.

Embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

As shown in Figure 1 and Figure 2, a kind of novel transformer structure, comprise secondary coil 1, U sections core 2, insulation board 3, aluminium skin 4, anchor ear 5, primary coil 6 and metal pins 7, three U sections cores 2 are arranged in a row, and totally four rows form an integral body, and front-back covers layer of aluminum skin 4 up and down, anchor ear 5 tightens together aluminium skin 4 and U sections core 2, middle two row U sections cores, 2 integral body are as magnetic core, and primary coil 6 and secondary coil 1 are wrapped in around it, and epoxy resin is poured at place, the inner slit of transformer.Totally eight layers of primary coils 6, every layer top and bottom are provided with insulation board 3.Secondary coil 1 is arranged on the middle of primary coil 6.Secondary coil 1 is that a cross section is foursquare rectangular, and its sectional dimension is 20mm * 20mm.Secondary coil 1 is one of the forming with metal pins 7.Metal pins 7 is " L " type, which is provided with the limbers of four diameter 8mm.

This novel transformer structure has not only reduced the electromagnetic eddy loss owing to adopted U sections core 2, has reduced impedance, exerts oneself but also improved.The sectional dimension of secondary coil 1 is 20mm * 20mm, and is bigger than the secondary coil cross-sectional area of traditional transformer, so just makes the electric current that unit are passes through increase, can better switching energy, can bursting by freezing at the environment of cold yet, and exert oneself but also improved.Metal pins 7 is provided with four limbers, when ambient temperature is too high, can lower the temperature to the limbers water flowing, and this damages with regard to having prevented transformer from working in hot environment for a long time, has improved its useful life.Every layer of top and bottom of primary coil 6 are equipped with one deck insulation board 3, and place, the inner slit of transformer poured epoxy resin, have so just strengthened its insulation property.
