Wherein, the insulating barrier outside described multi cord is made up of incombustible material.
Wherein, the double-layer coil in described insulation paper roll, secondary coil and the single layer coil in primary coil all use insulating tape to fix.
Wherein, described in the Copper Foil that is coated on outside the outer coil in secondary coil be fixed by being coated on the insulating paper volume outside it, described in the Copper Foil that is coated on outside two primary coils use and be welded and fixed.
Wherein, gap is left between the both sides that the Copper Foil that is coated on described in outside the outer coil in secondary coil is relative.
Wherein, the coiling direction of the multi cord in said two secondary coil and two primary coils is identical.
Wherein, the Copper Foil of said two secondary coil is all welded with earth lead with on the Copper Foil being coated on outside two primary coils, and three earth leads connect a binding post altogether.
Wherein, the end of the multi cord in said two secondary coil and two primary coils is all connected to binding post.
Wherein, two posts of described U-shaped magnetic core axially having along it through hole respectively, it is fixing that the U-shaped magnetic core of said two carries out docking by the cooperation of the through hole on bolt and two post.
The beneficial effects of the utility model are: this utility model simple in construction, easy to make, and the outer layer insulation of multi cord uses incombustible material, enhances the safety in utilization of transformator.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model is expanded on further.
As shown in Figure 1-Figure 3, a kind of transformator for high-power DC power supply, symmetrically structure, two secondary coils 2 including two U-shaped magnetic cores 1 docked in mode mouth to mouth, being respectively wound around on two posts of two U-shaped magnetic cores 1, two primary coils 3 being respectively wound around outside two secondary coils 2 and two primary coils 3 are coated on interior Copper Foil 4.As shown in Figure 3, two secondary coils 2 are respectively made up of along the double-layer coil 21,22 that the radial direction coiling number of turn of U-shaped magnetic core 1 post is identical a multi cord respectively, and use insulation paper roll 5 to be separated between U-shaped magnetic core 1 post and nexine coil 21, between double-layer coil 21,22, at outer Copper Foil 4 and the insulation paper roll 5 of being coated with the most successively of outer coil 22, and leave gap between the relative both sides of Copper Foil 4 herein.Two primary coils 3 are then made up of along the single layer coil 31 that the radial direction coiling number of turn of two secondary coils 2 is identical successively a multi cord, and are coated with insulation paper roll 5 at single layer coil 31.
Two secondary coils 2 are identical with the coiling direction of the multi cord in two primary coils 3.All it is welded with earth lead 6 with on the Copper Foil 4 being coated on outside two primary coils 3 on the Copper Foil 4 of two secondary coils 2, and three earth leads 6 connect a binding post altogether.The end of the multi cord in two secondary coils 2 and two primary coils 3 is the most all connected to binding post.
In this utility model, the insulating barrier outside multi cord is made up of incombustible material, substantially increases the safety of transformator.
