Embodiment
A kind of oil immersed water cool plating transformator 100(is called for short transformator 100), including: magnetic core 11, tank envelope 14, fuel tank cap 15, fuel tank cap fixed screw 18, mould frame 2, primary coil 1, secondary copper pipe 3, centre tap 4, heat radiation copper bar 5, copper pipe insulating support 13, bakelite plate 23, oil-proof rubber circle 20, oil resistant sealing gasket 17, oil filler point 19, rectifier tube 6, fixed support 16, connect sheet fixed screw 7 and joint 10.
Magnetic core 11 is placed in tank envelope 14, fuel tank cap 15 and tank envelope 14 are equipped with, and fixed by fuel tank cap fixed screw 18, oil resistant sealing gasket 17 it is provided with between fuel tank cap 15 and tank envelope 14, wherein, tank envelope 14 degree of protection is IP53, offers oil filler point 19 in fuel tank cap 15, refuels when refueling and safeguard later after facilitating transformator to install；Oil tank of transformer fuel tank cap 15 is two pieces of separate design so that the centre of two pieces of fuel tank cap reserves a magnetic gap ventilation line 21, can effectively reduce transformer loss, improve transformer efficiency；
Magnetic core 11 is ONL iron based nanocrystalline magnet core, and magnetic core 11 periphery is surrounded with moulds frame 2；
According to transformer parameter, primary coil 1 strand copper wire requires that (wire diameter and the number of turn) is wound on transformator and moulds on frame 2, the two ends of primary coil are drawn out to outside oil tank of transformer shell 14, and (offering the aperture for primary coil 1 traverse in fuel tank cap 15) is convenient to be connected；
Frame 2 of moulding outside secondary copper pipe 3 wounded core 11 fixes (caliber and the number of turn that customize secondary copper pipe according to the size of primary coil 1), and the through hole (not indicating through hole in figure) in secondary copper pipe 3 two ends fuel tank cap 15 is drawn outside fuel tank cap 15 so that primary coil 1 and secondary copper pipe 3 insulation are arranged.Wherein, secondary copper pipe 3 can be bonded by fixing means with moulding frame 2 glue, and adhesive tape is fixed, and through hole edge is provided with defensive oil-proof rubber circle 20；
Secondary copper pipe 3 after winding welds the output copper bar of bending as centre tap 4 so that centre tap 4 stretches out through the fuel tank cap 15 of oil tank of transformer shell 14；Fuel tank cap 15 is provided with fixed support 16, is used for fixing centre tap 4.
On secondary copper pipe 3, the fixing heat radiation copper bar 5(of welded and installed rectifier tube 6 is called for short heat radiation copper bar 5), also copper bar can be added according to the size of transformator output, for filling rectifier tube 6(Schottky), (rectifier tube 6 rectifier tube fixed screw 8 is fixed) composition power rectifier output circuit, facilitates High-current output；
Add joint 10 at transformer secondary output copper pipe 3 two ends, be respectively used to into water and water outlet (can arbitrarily select), make transformer secondary output copper pipe 3 water flowing can cool down transformator 100；
At secondary 3 times installation copper pipe insulating supports 13 of copper pipe so that secondary copper pipe 3 insulate with oil tank of transformer shell 14；
