Abstract
The utility model discloses an energy-saving high-frequency transformer, which comprises an iron core, a coil and a protecting device used for preventing overloading, short circuit and overheating of the transformer. The section of the iron core is in an elliptical structure, the coil is in an elliptical structure, and at least one protecting layer covers on each of the upper surface and the lower surface of the iron core. The energy-saving high-frequency transformer has the advantages of safety, energy conservation and long service life.
Description
Technical field
The utility model relates to transformer, relates in particular to a kind of energy-conservation high frequency transformer.
Background technology
In circuit, transformer is widely used element, is the device of conversion alternating voltage, electric current and impedance, when being connected with alternating current in the elementary coil, just produces exchange flux in the iron core (or magnetic core), makes and induces voltage (or electric current) in the secondary coil.Transformer is made up of iron core (or magnetic core) and coil, and coil has two or more windings, and the winding that wherein connects power supply is primary coil, and remaining winding is secondary coil.The function of transformer in circuit mainly contains: voltage transformation, impedance conversion, isolation, voltage stabilizing or the like.
High frequency transformer is a kind of high pressure to be converted to the power supply unit of low pressure, and its basic structure is the same with conventional transformer, has magnetic core and winding to constitute.At present, general high frequency transformer is made up of primary coil (high-pressure section), secondary coil (low-pressure section) and ancillary coil (elementary low-pressure section), its general coiling be in proper order by primary coil to ancillary coil again to secondary coil, isolate with insulating tape between every group of coil.This just causes that existing high frequency transformer volume is big, dielectric loss is high, leakage inductance and stray capacitance are big, has seriously restricted the raising of its high frequency characteristics.On the other hand, unshakable in one's determination surface exposed, be corroded easily, shorten the useful life of transformer.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides that a kind of loss is low, energy-saving effect is obvious, and long service life energy-conservation high frequency transformer.
To achieve these goals, the technical solution of the utility model is: a kind of energy-conservation high frequency transformer, comprise iron core and coil, and described core section shape is made as ellipsoidal structure, and coil shape is the elliptical shape structure; Described high frequency transformer also comprises and is used to prevent transformer overload, short circuit, overheated protective device.
Described protective device comprises that being used for transformer fault generates heat and disconnect the bimetal leaf of transformer frequency response when serious and be used to prevent to disconnect the automatically reset PTC thermistor of bimetal leaf, bimetal leaf and the primary side that is series at transformer after the PTC thermistor is in parallel.When transformer overload or short circuit, can cut off the input power supply automatically, the accident that prevents takes place.
In order to increase the antiseptic power on surface unshakable in one's determination, prolong the useful life of low-frequency transformer, on the upper and lower surface of described iron core, cover layer protective layer at least.
Compared with prior art, the utility model is owing to adopted the iron core of elliptic cross-section, and the cross section increases, and make magnetic circuit compact more, and the circular lamination of the wide ratio of oval lamination is wide little, helps economical with materials, improves cost performance of product; Set up protective layer by surface, can increase the antiseptic power on surface unshakable in one's determination, prolong the useful life of low-frequency transformer at silicon steel plate core; On the other hand, set up the protective device of being made up of bimetal leaf and PTC thermistor, prevent transformer overload, short circuit, overheated, it is safer that transformer is used.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
A kind of energy-conservation high frequency transformer of the utility model comprises iron core and coil, and described core section shape is made as ellipsoidal structure, and as shown in Figure 2, coil shape is the elliptical shape structure; As shown in Figure 1, described high frequency transformer also comprises and is used to prevent transformer overload, short circuit, overheated protective device 1.As shown in Figure 3; protective device 1 comprises and is used for the generate heat bimetal leaf 2 that disconnects transformer frequency response when serious and be used to prevent to disconnect the automatically reset PTC thermistor 3 of bimetal leaf of transformer fault, is series at the primary side of transformer after bimetal leaf 2 and PTC thermistor 3 are in parallel.Bimetal leaf 2 is the closed or switch that disconnects under assigned temperature, and when temperature raise, bimetal leaf 2 flexural deformations returned to reset condition again after the temperature reduction.PTC thermistor 3 has the constant temperature heat generation characteristic.When transformer overload or short circuit, the transformer heating is serious, the heat protection rated value that temperature rises and surpasses bimetal leaf 2; bimetal leaf 2 disconnects; at this moment voltage is added in PTC thermistor 3 two ends, and PTC thermistor 3 self-heatings heat up and make resistance enter the transition district, enter temperature constant state.By the heat of PTC thermistor 3, bimetal leaf 2 can not lowered the temperature reset.The power supply that is disconnected input after fault is got rid of is by reclosing, and bimetal leaf 2 resets, and transformer recovers operate as normal.
Further, all expose on upper and lower two surfaces generally unshakable in one's determination, in order to increase the antiseptic power on surface unshakable in one's determination, prolongs the useful life of low-frequency transformer, covers layer protective layer at least on the upper and lower surface of iron core.
