Abstract
The invention relates to the technical field of transformers, in particular to an insulated cooling ring transformer. The insulated cooling ring transformer 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 sequentially wound on the annular iron core; an epoxy resin insulating pipe is embedded into the center of a ring transformer body; insulated metal cover boards are arranged at the top and the bottom of the ring transformer body; and the metal cover boards and the ring transformer body sleeve bolts, and are fixed through nuts matched with the bolts. The insulated cooling ring transformer provided by the invention is high in insulation grade; iron loss and copper loss caused by temperature rise of the transformer are effectively retarded; manufacturing is convenient; the insulated cooling ring transformer has good heat dissipation performance, and is safe to use; and the operation reliability of the transformer is improved.
Description
Technical field
The present invention relates to transformer technology field, especially a kind of insulating radiation toroidal transformer.
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 insulating radiation toroidal transformer, comprise toroidal transformer body, there is an annular core, be around in the primary winding coil on annular core and secondary winding coil successively, described toroidal transformer body central place is equipped with epoxy resins insulation pipe, the top of described toroidal 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 are fixed by the nut coordinated with bolt.
Further, described primary winding coil and secondary winding coil are all coated with polyester film outward, serve effective insulation effect.
Further, by Copper Foil interval between described primary winding coil and secondary winding coil, can play the effect of screen, the waveform that transformer is exported is more level and smooth.
The invention has the beneficial effects as follows, the insulating radiation toroidal transformer class of insulation of the present invention is high, effectively slow down iron loss and copper loss that the temperature rise due to transformer causes, easily manufactured, and there is good heat dispersion, 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. primary winding coil, 3. secondary winding coil in figure, 4. epoxy resins insulation pipe, 5. metal cover board.
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.
Insulating radiation toroidal transformer as shown in Figure 1, comprise toroidal transformer body, there is an annular core 1, be around in the primary winding coil 2 on annular core 1 and secondary winding coil 3 successively, toroidal transformer body central place is equipped with epoxy resins insulation pipe 4, the top of toroidal transformer body and bottom are provided with the metal cover board 5 through insulation processing, metal cover board 5 and toroidal transformer body are set on bolt, and fixed by the nut coordinated with bolt, 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.In order to improve insulation effect further, outside primary winding coil 2 and secondary winding coil 3, be all coated with polyester film.By Copper Foil interval between primary winding coil 2 and secondary winding coil 3, effective shielding action can be played, the waveform that transformer is exported is more level and smooth, and coated mode is that Copper Foil is wound around primary winding coil 2, and when each winding one circle, Copper Foil all superposes.
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.
