Abstract
The utility model relates to a high-powered and high-frequency transformer comprising transformer iron cores, windings, and an insulating layer. The iron cores are U-shaped or cylindrical ferrites. The primary winding is a high-frequency winding wire and 1-6 secondary windings are common enameled wire windings. The insulating layer is the combination of a paper insulating layer and a reinforcing insulating layer. The reinforcing insulating layer which is a film made of polyimide or polyester is added in the paper insulating layer, thereby the insulation strength of the transformer is ensured effectively. The utility model has the advantages of simple structure, easy processing and production, high work efficiency and less waste due to the adoption of ferrite iron cores, small size and high power due to the high-frequency windings and the reinforcing insulating layers, therefore the utility model is applicable to the front terminals of various rectifier circuits.
Description
Affiliated technical field
The utility model relates to a kind of high-power high-frequency transformer, is applicable on the high-power high-frequency high-voltage DC power supply device to use.
Background technology
At present, high frequency transformer commonly used is used for electronic product more, and the operating frequency that has can be very high, but can't realize more high-power; The electronic product that sell the open market mostly is about 500W～2000W, becomes direct current with the inversion principle and exports, and can realizing of having is more high-power, but operating frequency is generally between 20kHz-30kHz, if frequency promotes again, then power does not increase.And some powerful DC power supply device are in order to reduce the volume of equipment at present, and especially the volume of transformer often needs to improve operating frequency, and existing technology can't be in the higher frequency of more high-power realization down.
Summary of the invention
In order to solve the contradiction between operating frequency and the power, effectively reduce the volume of power-supply device, the utility model has designed a kind of high-power high-frequency transformer, this high-power high-frequency transformer maximum operating frequency can reach 200kHz, short-time rating can reach 50kW, and the long period, power can reach 30kW when working, this transformer adopting oil-impregnated paper insulation is suitable for being connected on the front end of rectification circuit.
The utility model structural design is achieved in that the structure of this high-power high-frequency transformer forms (as shown in Figure 1) by iron core, winding and insulating barrier three parts, wherein the transformer core both sides are U type magnetic core, side arm is cylindrical, the centre is added with the column type magnetic core, used column type core diameter and endoporus and U type magnetic core side arm consistent (as shown in Figure 2); The iron core permeability is 2000, transformer has winding, a secondary winding to can be 1～6; Transformer voltage ratio is 15: 330, and a umber of turn is 10～20 circles, and the secondary winding number of turn is 220～440 circles, and a lead is the high frequency winding wire, and sectional area is 6mm
2, the secondary lead adopts common enamelled wire, and nominal diameter is about 0.25mm; Insulation system is once and adopts thickness between the secondary winding is the cable paper insulation of 0.125mm, shared 22 layers, add one deck reinforced insulation layer therebetween, material is polyimide film or polyester film, with 11 layers of cable paper insulation, adds one deck reinforced insulation layer between the 6th and 7 layer between the secondary winding, the oil resistant insulating adhesive tape is adopted in the end insulation, being close to a winding and adding a cardboard insulating barrier, extend to about outer each 20mm of line bag, is a small-sized high-power high frequency transformer after being assembled into.
Advantage: simple in structure, processing is easy, adopts ferrite iron core, the operating frequency height, and loss is little, adopts high frequency winding and reinforced insulation layer, makes transformer can reach that volume is little, power is big, is adapted at that front end uses in the various rectification circuits.
