The specific technical solution of the present invention and its advantages will in the following detailed description in conjunction with attached drawing into
Row detailed description.
Detailed description of the invention
Present invention will be further described below with reference to the accompanying drawings and specific embodiments:
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is side schematic view of the invention.
Specific embodiment
Referring to fig. 1 and fig. 2, a kind of inset type multiple-grooved high-power transformer, including the transformer bone being combined into one
Frame and magnetic core, the transformer framework include middle post holes 11, surround the baffle 12 that middle post holes is entirely circumferentially arranged, the baffle packet
Include two pieces of middle baffle plates of top flap, bottom baffle and centre, the face side and the back side of the top flap and bottom baffle
Side is equipped with the protrusion 13 (both direction that front and back is relatively middle 11 both ends of post holes herein) of protrusion surface, the top
Baffle and bottom baffle form the magnetic core locating slot of positioning magnetic core between bumps, and post holes 11 in the insertion of magnetic core center pillar, bottom plate is fixed
Positioned at magnetic core locating slot, strong fix is formed.Winding slot, i.e. the first winding slot P-1, second are formed between adjacent two block baffle
Winding slot P-2, third winding slot P-3.Primary coil is equipped in the winding slot, primary coil reduces using slot coiling is divided
Voltage stress.
The baffle (top flap, bottom baffle and two pieces of middle baffle plates of centre) is equipped with card slot, i.e. the first card slot S-
