Abstract
The utility model discloses a switching mode power supply transformer with high power. Comprising a magnetic core, a primary coil and a secondary coil, the utility model is characterized in that the magnetic core is a unit of iron core or is made up of a plurality of units of iron core bound together in parallel. The unit of iron is pieced together by two U iron cores face to face. Enwound on the magnetic core, one or two or ten secondary coils are arranged and central tap of each secondary coil is connected together. The primary coil can be either enwound directly on the magnetic core or on a wire-bag of a framework and the magnetic core is sheathed with the wire-bag. Compared with prior art, the utility model achieves the requirement of high power which enables 2000A output power.

Described transformer is characterized in that described primary coil is to be entwined around the skeleton of hollow by copper cash or copper sheet, and is enclosed within on the magnetic core by skeleton.
Described transformer, it is characterized in that described magnetic core be by two to six iron core unit side by side bonding after, tying watchman's wooden clapper with the insulation gauze is one, secondary coil is two to four, each secondary coil is two or four circles, is formed by the copper sheet coiling.
Described transformer is characterized in that primary coil is one to 20, with steel band magnetic core is tied watchman's wooden clapper and fixes, and described primary coil is connected mutually.
The utility model transformer is formed by magnetic core, secondary coil and elementary coiling, insulation board combination coiling.
Compare with prior art, the utility model has reached powerful requirement, makes out-put supply can reach 2000A.

Embodiment
Example 1
Shown in Fig. 1,3,4, the fourth officer magnetic core 5,6,12,13 of transformer (model is 22 * 31 for the UU80 cross section) is fixed together with glue side by side and around last industrial gauze, used quantity is fixed according to transformer efficiency.Every secondary magnetic core is an iron core unit, is put together relatively by two U sections cores.
The enamelled wire in suitable line footpath is selected in elementary (former limit) coil 14 lines footpath according to elementary (former limit) size of current, the utility model adopts the multiply enamelled wire to be wound on together, put high warm sleeve then, primary coil 14 numbers of turn are determined according to the quantity of input voltage and magnetic core.As input voltage AC380V, switching frequency 18K, output voltage are 12V, output current 2000A, and then can calculate the former limit number of turn is 26 circles, secondary is a circle, then according to secondary, the big or small definite line of primary current footpath.Secondary (secondary) coil of transformer has two groups, for secondary coil 2, secondary coil 4, two circles is arranged respectively, is formed by the copper sheet coiling.Secondary coil 2 passed magnetic core and arrives centre tap 3 arrival secondary electrodes 11 from 20 beginnings of secondary electrode, finished two circles.Secondary coil 4 passed magnetic core and arrives centre tap 3 arrival secondary electrodes 10 from 1 beginning of secondary electrode, completed into two circles.The centre tap of secondary coil 2,4 connects together and is centre tap 3.Insulate by insulation board 7,8,9 between the secondary coil.
Transformer is fixed on the bracing frame 16, and supporting plate 15 is arranged between bracing frame 16 and the magnetic core.
Example 2
As Fig. 2,5, shown in 6, elementary (former limit) coil 18 is two groups, it is the line bag that is entwined around the skeleton of hollow by copper cash or copper sheet, then primary coil 18 is sleeved on symmetrically the left side of magnetic core 19 respectively by skeleton, on the right magnetic post, the skeleton that two U-iron cores are passed rank coil 18 at the beginning of two magnetic core 19 that is put together, with steel band magnetic core being tied watchman's wooden clapper fixes, two groups of elementary (former limit) coils 18 are composed in series whole elementary (former limit) coil mutually, draw two tap a, b, elementary (former limit) coil 18 usefulness thickness δ=0.15mm or 0.35mm, wide W=70mm copper platinum and insulating paper are wound on the skeleton with the magnetic core same model, the left side of magnetic core, the number of turn is identical on the magnetic post of right both sides, total required number of turn is that two monolateral number of turn additions are (if the former limit number of turn needs 30, the then monolateral number of turn is 15), the coiling number of turn and the required copper platinum thickness of selecting for use are determined according to elementary (former limit) electric current.Magnetic core is clamped by bailing band with two firm bankings 16,17 then, be fixed on the base plate.
Secondary (secondary) coil of transformer has two groups, for secondary coil 2, secondary coil 4, two circles is arranged respectively, is formed by the copper sheet coiling.Secondary coil 2 passed magnetic core and arrives centre tap 3 arrival secondary electrodes 11 from 20 beginnings of secondary electrode, finished two circles.Secondary coil 4 passed magnetic core and arrives centre tap 3 arrival secondary electrodes 10 from 1 beginning of secondary electrode, completed into two circles.The centre tap of secondary coil 2,4 connects together and is centre tap 3.Insulate by insulation board 7,8,9 between the secondary coil.
Fixed support 17 is two, is positioned at the and arranged on left and right sides of magnetic core 19, and its first half is the arc anchor clamps, just in time clamps magnetic core 19, and fixed support 17 lower ends are fixing feet, can be by being bolted on the base.
Exterior view last layer three at transformer after whole transformer assembling is finished is prevented lacquer, to strengthen the contamination resistance of transformer.
