Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
With reference to illustrated in figures 1 and 2, the utility model embodiment provides a kind of transformer, and Fig. 1 is a sectional view of transformer, and shown in Figure 2 is the sectional view of iron core 30 directions in the transformer.
Transformer in the present embodiment comprises: former limit winding 10 (part of filling with oblique line among Fig. 1), at least two secondary windings 20 and iron core 30; Below be that example describes with a secondary winding 21 (part of filling with vertical line among Fig. 1) with another root secondary winding 22 (part of filling with point among Fig. 1), particularly:
Former limit winding 10 and secondary winding 20 layering respectively are wound on the iron core 30, on one deck of secondary winding 20, and at least two secondary windings 20 parallel coilings, and the every winding that secondary winding 20 all is the bag insulating barrier; And between one deck of former limit winding 10 and one deck of secondary winding 20 insulating barrier 40 is arranged.
Wherein, the length of every secondary winding 20 can be identical, and behind winding 10 two ends, former limit inputs power supply, then the output voltage at every secondary winding 20 two ends is all identical like this, and can distortion; And if also can be different with the length of secondary winding 20, behind winding 10 two ends, former limit input power supply, then the output voltage at every secondary winding 20 two ends is all inequality, and can distortion like this.
Be appreciated that former limit winding 10 and secondary winding 20 can be the thin enamel covered wire of multiply, can be so that the caloric value of transformer be little and spread heat, promptly kelvin effect is less; And iron core 30 can be the ring-type iron core of nanocrystalline low remanent magnetism, and former limit winding 10 is in one deck coiling near iron core 30, and secondary winding 20 can reduce high frequency leakage inductance and distributed capacitance so greatly in one deck coiling away from iron core.
Insulating barrier 40 between one deck of former limit winding 10 and one deck of secondary winding 20 can comprise multi layer cloud master tape, glass tape and polyester-imide insulating tape; Can reach good insulation and adiabatic effect like this; Prevent that (Ingress Protection, IP) grade can reach IP65 in intrusion.
In transformer; If the number of turn of former limit winding 10 coilings is N1; Wherein the number of turn of a secondary winding 21 is N2; The number of turn of another root secondary winding 22 is N3, and then the output voltage at secondary winding 21 two ends is the former limit of (NI/N2) * winding 10 voltage, and the output voltage at secondary winding 22 two ends is the former limit of (NI/N2) * winding 10 voltage; And former limit winding 10 can be the same or different with the number of turn of secondary winding 20 coiling on iron core 30.Then can realize the variation of the output voltage of transformer through the number of turn that changes former limit winding 10 and 20 coilings of secondary winding.
Need to prove that though above-mentioned many secondary windings are parallel coilings, every winding all is the winding that is surrounded by insulating barrier, make like this and isolate each other between the every winding, and complementary the interference.
It is thus clear that in the transformer among the utility model embodiment, former limit winding 10 and secondary winding 20 layering respectively are wound on the iron core 30, and between one deck of one deck of former limit winding 10 and secondary winding 20 insulating barrier 40 are arranged.Because on one deck of secondary winding 20; At least two secondary winding 20 parallel coilings; Be wound on the iron core respectively with every secondary winding in the prior art and compare, in the transformer among the utility model embodiment, behind winding two ends, former limit input power supply; The waveform of the output voltage at every secondary winding two ends can distortion, and then the high-frequency energy efficiency of transmission of transformer is just than higher.And every secondary winding 20 parallel coilings can be saved the iron core of secondary winding technique, thereby made that the volume of transformer is less.
The utility model embodiment also provides a kind of potential device, and such as power frequency potential device or high-frequency transformation device etc., structural representation comprises transformer 100, former limit circuit 101 and secondary circuit 102 shown in 3, wherein:
