Description
Technical field
The present invention relates to a kind of transformer.
Background technology
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, and main member is primary coil, secondary
Level coil and iron core（Magnetic core）.Major function has：Voltage transformation, current transformation, impedance conversion, isolation, voltage stabilizing（Magnetic saturation transformation
Device）Deng.It can be divided into, according to use,：Power transformer and special transformer（Electric furnace change, rectification change, power frequency testing transformer, pressure regulation
Device, mining change, audio-frequency transformer, intermediate-frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer,
Reactor, transformer etc.）.
Transformer is the important component for forming power network, and it includes iron core and winding, Transformer Winding typically use aluminum steel or
Copper cash, aluminum steel winding transformer are better than copper cash winding transformer, and aluminum steel winding in the performance of loss, noise, temperature rise etc.
Transformer is more advantageous, but the anti-short circuit capability of aluminum steel winding transformer is not as good as copper cash winding transformer.Existing transformer
It is unstable in use.
Therefore, to solve the above problems, special provide a kind of new technical scheme.
The content of the invention
The present invention provides a kind of transformer.
The technical solution adopted by the present invention is：
A kind of transformer, including housing, magnetic core, coil and copper sheet, magnetic core is provided with the housing, is covered on the magnetic core wired
Circle, the coil both sides are provided with copper sheet, the both sides of magnetic core are provided with fin, heat emission hole is provided with the fin,
The fin is arranged on pedestal, and the pedestal is arranged in housing.
Further, it is provided with heat sink strip on the housing.
Further, the heat sink strip is corresponding with heat emission hole.
Further, a segment distance is left between the fin and magnetic core.
Further, the cross section of the magnetic core is octagon.
The beneficial effects of the invention are as follows：It is simple in construction, safe and convenient to use, the fin of use, can effectively it improve scattered
Thermal effect, the copper sheet and coil of addition, the problem of can effectively solve the problem that transformer short-circuit, improve stability.
Brief description of the drawings
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of the present invention.
Wherein：1st, housing, 2, magnetic core, 3, coil, 4, copper sheet, 5, fin, 6, heat emission hole, 7, pedestal, 8, heat sink strip.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, should
Embodiment is only used for explaining the present invention, does not form the restriction to protection scope of the present invention.
A kind of transformer as shown in Figure 1, including housing 1, magnetic core 2, coil 3 and copper sheet 4, magnetic core is provided with housing 1
2, coil 3 is cased with magnetic core 2, and the both sides of coil 3 are provided with copper sheet 4, and the both sides of magnetic core 2 are provided with fin 5, fin 5
On be provided with heat emission hole 6, fin 5 is arranged on pedestal 7, and pedestal 7 is arranged in housing 1, and heat sink strip 8 is provided with housing 1, is radiated
Bar 8 is corresponding with heat emission hole 6, a segment distance is left between fin 5 and magnetic core 2, the cross section of magnetic core 2 is octagon.
The beneficial effects of the invention are as follows：It is simple in construction, safe and convenient to use, the fin of use, can effectively it improve scattered
Thermal effect, the copper sheet and coil of addition, the problem of can effectively solve the problem that transformer short-circuit, improve stability.
The above described is only a preferred embodiment of the present invention, it is not the limit for making any other form to the present invention
System, and any modification made according to technical spirit of the invention or equivalent variations, still fall within present invention model claimed
Enclose.
