Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, the described high-frequency high-power transformer for large-scale adjustable power supply, comprise: skeleton 1, be arranged at the coiling cylindrical shell 2 in skeleton 1, iron core 3 is arranged in skeleton 1 and coiling cylindrical shell 2, in skeleton 1, be at least provided with three stacks and be set in the annular conductive film 4 on coiling cylindrical shell 2, in the present embodiment, in skeleton 1, be provided with five stacks and be set in the annular conductive film 4 on coiling cylindrical shell 2; Between adjacent two rings shape conducting strip 4, clog You Yige unit primary coil 5, unit primary coil 5 be sleeved on coiling cylindrical shell 2 Shang， unit primary coils 5 between adjacent two rings shape conducting strip 4 by along coiling cylindrical shell radially from inside to outside order around insulated conductor coiling form; Between unit primary coil 5 and adjacent annular conductive film 4 by insulating trip 6 mutually insulateds, all unit primary coil 5 armature windings that form in parallel, all annular conductive films 4 secondary winding that form in parallel; In the present embodiment, every annular conductive film 4 comprises the annular copper sheet that two orders are connected, between adjacent annular copper sheet, pass through insulating trip 6 mutually insulateds, because a slice annular copper sheet is equivalent to a circle secondary winding, in practical application, can increase by increasing the sheet number of annular copper sheet in annular conductive film 4 number of turn of secondary winding, thereby change the output of transformer; In the present embodiment, described insulating trip is insulating paper, and because insulating paper is not only thin, and insulation effect is good, so can not take in a large number the effective installing space in skeleton 1 after adopting insulating paper as insulating trip, be conducive to the smooth installation of annular conductive film and unit primary coil.Owing to forming the unit primary coil 5 of armature winding, be separately positioned on the coiling cylindrical shell 2 between adjacent annular conducting strip 4, be that unit primary coil 5 is embedded between two adjacent annular conducting strips 4, unit primary coil 5 is with annular conductive film 4 structure that arranges stacking gradually up and down, this structure makes the wire diameter of unit primary coil and the coiling number of turns all can not be subject to the restriction of the interior hole dimension of annular conductive film 4, thereby can improve the power output of transformer; And can be in the situation that do not affect the input power of unit primary coil 5, make the thickness attenuation of unit primary coil 5, thereby can be corresponding increase form the thickness of annular copper sheet in the annular conductive film 4 of secondary winding, improve the electric current ability to bear of annular conductive film 4, can further improve the power output of transformer.In actual applications, adopt the peak power output of the PQ50 type transformer of said structure can reach 5000W, highest frequency can reach 200 hertz.
