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 schematic diagram of the first skeleton in embodiment one；
Fig. 2 is the schematic rear view of the second skeleton in embodiment one；
Fig. 3 is the overall structure diagram of transformer in embodiment two.
Specific embodiment
The technical solution of the embodiment of the present invention one is explained and illustrated in conjunction with the attached drawing of the embodiment of the present invention one first,
As depicted in figs. 1 and 2, a kind of high-power Industry Control transformer, including transformer framework and it is mounted on the transformer framework
Interior magnetic core, the transformer framework includes the first skeleton 1 and the second skeleton 2, between first skeleton 1 and the second skeleton 2
For split type structure and the second skeleton 2 is nested in the first skeleton 1.In this example, it is related to the first skeleton and the second skeleton
The description of front and back is using the butt end of the first skeleton and the second skeleton as front, and the one side opposite with butt end is
The back side.The front center of first skeleton is equipped with groove 11, and the front center of second skeleton is equipped with protrusion 21, described convex
Portion 21 is entrenched in groove 11, and the bottom of the groove is equipped with the first through hole 112 of the first skeleton of perforation, and the protrusion is equipped with
The second through-hole 212 of the second skeleton is penetrated through, the magnetic core is mounted in the second through-hole, and first skeleton 1 is set around groove 11
There is the first winding slot, first coil winding is equipped in first winding slot, second skeleton 2 is set around the second through-hole 212
There is the second winding slot, second coil winding is equipped in second winding slot, the bottom surface of the groove is equipped with around first through hole
The top ring of the first annular tongue and groove 111 of multi-turn, the protrusion is equipped with the second annular concave-convex of multi-turn slot 211, institute around the second through-hole
It states first annular tongue and groove 111 and the second annular concave-convex slot 211 is concave-convex chimeric, the positive width in groove of first skeleton
Two sides are equipped with the first bar shaped tongue and groove 12, and the front of second skeleton is recessed equipped with the second bar shaped in the width two sides of the second through-hole
Tongue 22, the first bar shaped tongue and groove 12 and the second bar shaped tongue and groove 22 are concave-convex chimeric.It is embedding due to using concave convex groove structure
It closes, than the creepage distance that common plane fit structure increases by 50% or more, is more in line with safety requirement.
Wherein, the front of first skeleton is equipped with the first U-shaped mouth 13 in the first side of length, is equipped with the in length second side
