Technical field
The utility model relates to transformer technology field, especially a kind of toroidal transformer of belt supporting frame.
Background technology
Toroidal transformer is a large type of electronic transformer, has been widely used in home appliance and the higher electronic equipment of other technical requirement, and its main application is as power transformer and isolating transformer.Toroidal transformer is widely used in the aspects such as computer, Medical Devices, telecommunication, instrument and lighting, has the good ratio of performance to price, has good output characteristic and antijamming capability.Toroidal transformer insulation effect in existing technology is poor, and casualty accident easily occurs, dangerous reliable, and heating in winding amount, and radiating effect is bad, can affect it and normally work.
Utility model content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide the toroidal transformer that a kind of good insulation preformance and thermal diffusivity are good.
The utility model solves the technical scheme that its technical problem adopts: a kind of toroidal transformer of belt supporting frame, comprise transformer body, there is an annular core, what intermesh is set around the primary winding coil and the secondary winding coil that are around on annular core, described annular core is coated with copper foil layer, can play the effect of screen, make the waveform of transformer output more level and smooth.The top of described transformer body and bottom are provided with the metal cover board through insulation processing, metal cover board can play the effect of heat radiation, and entered insulation processing, can guarantee in the toroidal transformer course of work that the utility model provides, secondary winding coil not can because of dissipation of heat not in time, cause the harmful effect to whole toroidal transformer operating state, described metal cover board and toroidal transformer body are set on bolt, and fix by the nut coordinating with bolt, described transformer body bottom is provided with two metallic supports, described primary winding coil and secondary winding coil are drawn two lead-in wires separately, on described transformer body sidewall, be coated with one deck yellow varnished insulating cloth.
Further, described primary winding coil and secondary winding coil are all coated with polyester film outward, promote the class of insulation, have enough heat resistances, and have certain corrosion resistance.
Further, described metallic support two ends offer installing hole separately, convenient installation.
Further, described lead-in wire is coated with silica gel glass fibre sleeve, plays the effect of reinforcing, is not easy sealing-off.
Further, described metal support surface is coated with polyester enamelled coating, has played effective insulation effect.
The beneficial effects of the utility model are, the toroidal transformer of belt supporting frame of the present utility model is provided with metallic support, convenient installation, and the class of insulation is high, primary coil and secondary coil adopt apart from one another by winding method, can improve the power conversion rate of whole toroidal transformer, and there is good heat dispersion, effectively slow down the iron loss and the copper loss that cause due to the temperature rise of transformer, easily manufactured,, improve the operational reliability of transformer, use safety.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. annular cores in figure, 2. metal cover board, 3. bolt, 4. metallic support, 5. lead-in wire, 6. installing hole.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The toroidal transformer of belt supporting frame as shown in Figure 1, there is an annular core 1, on annular core 1, be wound with primary winding coil and secondary winding coil, primary winding coil and secondary winding coil adopt the canoe of space, it can more effective elimination leakage inductance, thereby improves the power conversion rate of whole toroidal transformer.Primary winding coil and secondary winding coil are all coated with polyester film outward, promote the class of insulation, have enough heat resistances, and have certain corrosion resistance.Primary winding coil and secondary winding coil are drawn two lead-in wires 5 separately, and lead-in wire 5 is coated with silica gel glass fibre sleeve, plays the effect of reinforcing, is not easy sealing-off.Annular core 1 is coated with copper foil layer, can play the effect of screen, makes the waveform of transformer output more level and smooth.The top of toroidal transformer and bottom are provided with the metal cover board 2 through insulation processing; metal cover board 2 can play the effect of heat radiation; and entered insulation processing; can guarantee in the toroidal transformer course of work; secondary winding coil not can because of dissipation of heat not in time; cause the harmful effect to whole toroidal transformer operating state; metal cover board 2 and toroidal transformer are set on bolt 3; and fix by the nut coordinating with bolt 3; transformer body bottom is provided with two metallic supports 4; metallic support 4 two ends offer installing hole 6 separately, convenient installation.Metallic support 4 surface-coated have polyester enamelled coating, have played effective insulation effect.In order to promote further the class of insulation, on toroidal transformer sidewall, be coated with one deck yellow varnished insulating cloth.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
