The utility model solves the technical scheme that its technical problem adopts: a kind of TV step-up transformer, comprise coil rack, the middle part of coil rack is wound with primary coil, the both sides of coil rack are secondary coil of coiling respectively, be respectively the first secondary coil and second subprime coil, two secondary coils are cascaded;
Above-mentioned primary coil comprises two primary coil joints, is respectively primary coil joint A and primary coil joint B, and two primary coil joints are connected with 12V alternating voltage; Same each self-contained two coil connectors of described two secondary coils, are respectively level coil connectors A first time, first level coil connectors B and second subprime coil connectors A, second subprime coil connectors B; First level coil connectors A and second subprime coil connectors B link together, first level coil connectors B and second subprime coil connectors A output 4000V alternating voltage;
Above-mentioned coil rack two ends are provided with insulation board, coil rack inside arranges cavity, the magnetic core that also comprises two E type structures, crossbeam in the middle of the magnetic core of E type structure comprises and the side bar of both sides, after magnetic core is inserted by the both sides of coil rack respectively, crossbeam stretches in coil rack cavity, side bar by the coil on coil rack around, the side bar joint of two magnetic cores is provided with air gap sheet; Above-mentioned two magnetic cores are simultaneously fastening by jump ring;
Between above-mentioned magnetic core and coil rack, also by glue, fix.
As a kind of improvement of winding structure on above-mentioned coil rack, described primary coil and secondary coil outer wrap have insulating tape.
As a kind of preferred implementation of above-mentioned insulating tape, described insulating tape is epoxy adhesive tape.
A kind of TV step-up transformer described in the utility model, it has the following advantages:
The utility model TV step-up transformer, it adopts a primary coil and two groups of secondary coils, and every group of output AC voltage 2000V is linked togather common output 4000V alternating voltage by two groups of output strings, meet high designing requirement of boosting, reduced volume of transformer simultaneously; Meanwhile, the utility model is by air gap sheet is set, jump ring and bonding structure, make magnetic core more reliable with being connected of coil rack, realized efficient high power and safe and reliable advantage, the insulation board by coil rack both sides reliably insulate simultaneously, further promotes safety.
