Detailed description of the invention

It should be noted that in the case of not conflicting, following technical proposals, can be mutually combined between technical characteristic.

The present embodiment provides a kind of transformator, can not only dust-proof, waterproof, the making work of transformator can also be simplified simultaneously Skill, the basic functional principle of the transformator of the present embodiment is electromagnetic induction principle, hands over after alternating voltage is added to first side winding Stream electric current flows into this winding and just produces excitation effect, produces the magnetic flux of alternation in the core, and this alternating flux is not only through one Secondary side winding, simultaneously also through secondary side winding, it causes induction electromotive force respectively in two windings.If at this moment secondary side Load with external circuit is connected, and just has alternating current to flow out, then exports electric energy.Three single-phase transformers are combined and i.e. forms such as Three-phase transformer shown in Fig. 1.The operation principle of three-phase transformer and single-phase transformer are identical. in three-phase transformer, Each stem stem is all wound with primary winding (first side winding) and auxiliary winding (secondary side winding), each stem stem be equivalent to one single-phase Transformator.

With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings, but not as this practicality Novel restriction.

As in figure 2 it is shown, the present embodiment is illustrated with a stem stem in three-phase transformer, remaining stem stem and this enforcement The structure of the stem stem of example can be identical, but is not limited to this, and in Fig. 2, this stem stem includes iron core, and the material of iron core can be silicon steel Sheet, coil is wound on iron core.

Further, the coil of the present embodiment is many C level enamel insulated round copper wire, the cross section of every C level enamel insulated round copper wire Long-pending being respectively less than 100 square millimeters, it is specified that the value of the cross-sectional area of concrete C level enamel insulated round copper wire needs according to three-phase transformer Voltage is determined.

By using many C level enamel insulated round copper wire, can not only reach electrical by the basis of regulation C level enamel insulated round copper wire Requirement, additionally, due to the cross-sectional area of C level enamel insulated round copper wire reduces, both can carry out coil by the way of machine is wound around It is wound around, instead of and original be wound around manually, improve the production efficiency of transformator, the softness of single C level enamel insulated round copper wire Property also preferable, once a C level enamel insulated round copper wire is damaged, follow-up maintenance and change the most more convenient, additionally, many C Level enamel insulated round copper wire from the appearance comes the most attractive in appearance, it is simple to heat radiation.

Further, the coiling of the present embodiment coil uses flat wire coiling, further improves radiating effect.

Further, the coil outer of the present embodiment is covered with a protective layer as external insulation, and this protective layer can be blue or green , can there is a certain distance, and not exclusively be adjacent to coil in highland barley paper (DMD paper), the making of Semen avenae nudae paper between protective layer and coil Technique needs Semen avenae nudae paper is immersed varnish, owing to Semen avenae nudae paper has certain hard toughness, the work of coil protection can be played With, prevent coil broken skin, so that using dangerous, the protective layer in the present embodiment is dust-proof, waterproof, and the operation for transformator provides One environment the best.

In the present embodiment, the upper part of iron core is utilized a train wheel bridge to fix by the first bolt assembly, as in figure 2 it is shown, in like manner, The lower part of iron core is utilized Boards wall by the second bolt assembly, and wherein, the first bolt assembly and the second bolt assembly can To include screw rod, nut, pad etc..

As it is shown on figure 3, the three-phase transformer in the present embodiment can be booster transformer, with the booster transformer in Fig. 3 Illustrating, the input voltage of such as first side winding can be 400V, and the output voltage of secondary side winding can include two kinds Specification, respectively 450V and 500V two kinds, its first side winding can use the mode of connection of corner connection, as shown in Figure 4, secondary side Winding can use the mode of connection that star connects.

In Fig. 3, joint 1,2,3 is three inputs of first side winding, and 4,6,8 is the defeated of secondary side winding 450V voltage Going out end, 5,7,9 is the outfan of secondary side winding 500V voltage.

In sum, three-phase transformer of the present utility model is provided with protective layer, and protective layer can be dust-proof, waterproof, shields Extraneous adverse circumstances so that transformator can run in a environment the best, improves the performance of transformator, this Outward, the coil of this three-phase transformer also uses much thinner enamel insulated round copper wire, it is simple to uses machine to carry out coiling, improves The manufacture efficiency of three-phase transformer, also allows for follow-up maintenance simultaneously.

Above preferred embodiment of the present utility model is described.It is to be appreciated that this utility model not office Being limited to above-mentioned particular implementation, the equipment not described in detail the most to the greatest extent and structure are construed as with the common side in this area Formula is practiced；Any those of ordinary skill in the art, without departing under technical solutions of the utility model ambit, may be used Technical solutions of the utility model are made many possible variations and modification by the method and the technology contents that utilize the disclosure above, or repair Changing the Equivalent embodiments of equivalent variations into, this has no effect on flesh and blood of the present utility model.Therefore, every without departing from this practicality The content of new technique scheme, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, etc. With change and modification, all still fall within the range of technical solutions of the utility model protection.
