Abstract
The invention relates to the field of electronic transformers, in particular to an electronic transformer which comprises a wire rack and a wire part. The wire part comprises a plurality of strands of twisted wires, each strand of wires is formed by a plurality of wires in a twisted mode, and the strands of twisted wires are wound on the wire rack. According to the electronic transformer, the wires are twisted into a strand and then are wound together to form the twisted wires, so that the effective surface area of unit cross-sectional area wires is increased, limited conductor surfaces are utilized to the largest extent, and the skin effect is greatly lowered. By means of the electronic transformer, the utilization efficiency under the same wire diameter is increased, the heat generating amount of the electronic transformer is lowered, the service life is prolonged, meanwhile, the interference effect of a single copper wire in the working process is lowered, and the electronic transformer can normally work more stably.
Description
Technical field
The present invention relates to electronic transformer field, particularly a kind of electronic transformer.
Background technology
Electronic transformer is exactly without voltage regulation type Switching Power Supply, and in fact it is exactly a kind of inverter.First AC rectification is become to direct current. then with a high-frequency generator of electronic component composition, direct current is become to high-frequency alternating current, by switch transformer export needed voltage then secondary rectification for electrical appliance.It is little that Switching Power Supply has volume, lightweight, the application of advantage electronic transformer in traditional lighting light fixture such as price is low is very general, as fluorescent lamp, desk lamp, electricity-saving lamp, advertising lamp etc. nearly all can use electronic transformer, and after employing electronic transformer, can save starter.At LED(light-emitting diode) illumination in, new product also mostly adopts electronic transformer.Be mainly electronic transformer on transformation function, efficiency is high, at the bottom of cost, save iron copper product, structure is little, lightweight.
At present, the electronic transformer product using adopts the mode operation of single copper cash or the many parallel coilings of copper cash, thereby is subject to the impact of skin effect.In electronic transformer, when alternating current passes through conductor, because induction effect causes that on cross-sectional area of conductor, CURRENT DISTRIBUTION is inhomogeneous, nearer conductive surface current density is larger.This phenomenon claims " skin effect ".Skin effect increases the effective resistance of conductor.When the very high electric current of frequency is during by wire, can think that electric current only flows through in very thin one deck in conductive line surfaces, this cross section that is equivalent to wire reduces, and resistance increases.Bigger than normal because of the loss that skin effect causes, cause temperature rise higher, product reduces useful life, does not also meet energy-conserving and environment-protective requirement, simultaneously anti-tampering scarce capacity.
In order to overcome the above problems, the present invention has done useful improvement.
Summary of the invention
(1) technical problem that will solve
The object of this invention is to provide a kind of electronic transformer, can reduce the loss causing because of skin effect, cause the caloric value that reduces electronic transformer.
(2) technical scheme
The present invention is achieved by the following technical solutions: a kind of electronic transformer, comprises coil holder and wire segment; Described wire segment comprises strands wire rod, and per share stranded wire rod is by many stranded the forming of wire rod; Described strands wire rod is wound on described coil holder.
Wherein, described many wire rods have identical sectional area.
Further, every wire rod is enamelled wire.
Wherein, every wire rod is copper cash.
Particularly, the outer wrap of the stranded wire rod of described sub-thread has empire silk.
(3) beneficial effect
Compare with product with prior art, the present invention has the following advantages:
1, per share stranded wire rod of the present invention adopts many wire rods to be twisted into after one, then coiling forms, and the effective surface area of unit cross-sectional area wire rod is increased, and has utilized to greatest extent limited conductive surface, and skin effect is reduced greatly.
2, the present invention increases the utilization ratio under identical wire diameter, reduces the caloric value of product, increases the service life, and the interference effect having produced while simultaneously having reduced single copper cash work, makes the more stable normal work of product.
Brief description of the drawings

Fig. 2 is the structure chart of the stranded wire rod of sub-thread of the present invention.
In accompanying drawing, the component list of each label representative is as follows:
1, magnetic core; 2, wire segment; 3, coil holder; 21, the stranded wire rod of sub-thread
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
The present embodiment provides a kind of electronic transformer, and this electronic transformer comprises magnetic core 1, wire segment 2, coil holder 3, magnetic core, Copper Foil and sleeve pipe etc.As depicted in figs. 1 and 2, described wire segment 2 comprises strands wire rod, and per share stranded wire rod 21 is by many stranded the forming of wire rod; Described strands wire rod is wound on described coil holder 3, then is arranged on magnetic core 1.Many wire rods are twisted into one wire rod and obtain one stranded wire rod.Every wire rod can adopt enamelled wire to make, and particularly, can adopt enamel covered wire to make.Electronic transformer in the present embodiment, adopts many stranded wire rod coilings, will originally singlely adopt some thin wires to be twisted into the stranded wire rod of sub-thread compared with heavy wire and replace.Per share stranded wire rod can pass through stranding machine twisted together, then carries out this electronic transformer coiling, makes the effective surface area of unit cross-sectional area wire rod increase by two to three one-tenth, has utilized to greatest extent limited wire conductor surface, and skin effect is reduced greatly.
The electronic transformer that the present embodiment provides, can adopt many copper cash synchronous rotaries, evenly stranded rear coiling electronic transformer product.Wherein, for the thicker wire rod of wire diameter, can be twisted into the stranded wire rod of sub-thread with many long-pending wire rods of same cross-sectional and carry out operation, simultaneously can be at the empire silk of the outer parcel of the stranded wire rod of sub-thread layer, form one and wrapped up by outer layer insulation silk, the sub-thread silk-covered wire that internal layer is copper cash.
The application of electronic transformer in traditional lighting light fixture is very general, as fluorescent lamp, desk lamp, electricity-saving lamp, advertising lamp etc. nearly all can use electronic transformer, and after adopting electronic transformer, can save starter.In LED illumination, new product also mostly adopts electronic transformer.Be mainly electronic transformer on transformation function, efficiency is high, at the bottom of cost, save iron copper product, structure is little, lightweight.Not enough is that withstand voltage and resistance to high current surge withstanding capability is poor compared with irony transformer.
Above execution mode is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
