Abstract
The invention relates to a ring transformer with a bracket. The ring transformer comprises a transformer body, wherein the transformer body comprises an annular iron core, a primary winding coil and a secondary winding coil, wherein the primary winding coil and the secondary winding coil are wound on the annular iron core in an interlacing manner; the annular iron core is wrapped with a copper foil layer; metal cover boards are arranged at the top and the bottom of the transformer body; the metal cover boards and the ring transformer body sleeve bolts, and are fixed through nuts matched with the bolts; two metal brackets are arranged at the bottom of the transformer body; and two leads are respectively led out from the primary winding coil and the secondary winding coil. The ring transformer with the bracket provided by the invention is provided with the metal brackets, so that installation is facilitated; the insulation grade is high; the power conversion rate of the overall ring transformer can be increased; the ring transformer has good heat dissipation performance; the iron loss and the copper loss caused by temperature rise of the transformer are effectively retarded; the operation reliability of the transformer is improved; and use is safe.
Description
Technical field
The present invention 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, and be widely used in the home appliance electronic equipment higher with other technical requirement, 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 excellent ratio of performance to price, has good output characteristic and antijamming capability.Toroidal transformer insulation effect in existing technology is poor, easily casualty accident occurs, reliably dangerous, and heating in winding amount, radiating effect is bad, can affect it and normally work.
Summary of the invention
The technical problem to be solved in the present invention is: for overcoming above-mentioned Problems existing, provides a kind of good insulation preformance and the good toroidal transformer of thermal diffusivity.
The technical solution adopted for the present invention to solve the technical problems is: a kind of toroidal transformer of belt supporting frame, comprise transformer body, there is an annular core, being set around of intermeshing is around in primary winding coil on annular core and secondary winding coil, described annular core is coated with copper foil layer, can play the effect of screen, the waveform that transformer is exported is 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 provided by the invention, secondary winding coil can not distribute not in time because of heat, cause the harmful effect to whole toroidal transformer operating state, described metal cover board and toroidal transformer body are set on bolt, and fixed by the nut coordinated with bolt, two metallic supports are installed bottom described transformer body, described primary winding coil and secondary winding coil draw two lead-in wires separately, described transformer body sidewall is 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, serves effective insulation effect.
The invention has the beneficial effects as follows, the toroidal transformer of belt supporting frame of the present invention 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, the power conversion rate of whole toroidal transformer can be improved, and there is good heat dispersion, effectively slow down iron loss and copper loss that the temperature rise due to transformer causes, easily manufactured,, improve the operational reliability of transformer, use safety.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. annular cores, 2. metal cover board, 3. bolt, 4. metallic support in figure, 5. go between, 6. installing hole.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The toroidal transformer of belt supporting frame as shown in Figure 1, there is an annular core 1, annular core 1 is wound with primary winding coil and secondary winding coil, primary winding coil and secondary winding coil adopt spaced canoe, it can more effective elimination leakage inductance, thus 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 draw 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, and the waveform that transformer is exported is 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 can not distribute not in time because of heat; cause the harmful effect to whole toroidal transformer operating state; metal cover board 2 and toroidal transformer are set on bolt 3; and fixed by the nut coordinated with bolt 3; two metallic supports 4 are installed bottom transformer body; metallic support 4 two ends offer installing hole 6 separately, convenient installation.Metallic support 4 surface-coated has polyester enamelled coating, serves effective insulation effect.In order to promote the class of insulation further, toroidal transformer sidewall is coated with one deck yellow varnished insulating cloth.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
