Description
Technical field
The present invention relates to a kind of transformer, more particularly to a kind of copper sheet type 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 constituting power network, and it includes iron core and winding, Transformer Winding typically use aluminum steel or
Copper cash, performance of the aluminum steel winding transformer in terms of loss, noise, temperature rise is better than copper cash winding transformer, and aluminum steel winding
Transformer is more advantageous, but aluminum steel winding transformer anti-short circuit capability 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 copper sheet type transformer.
The technical solution adopted by the present invention is：
Magnetic core is provided with a kind of copper sheet type transformer, including housing, magnetic core, coil and copper sheet, the housing, the magnetic core
Upper and lower ends are cased with being provided with insulating trip on the outside of copper sheet, the copper sheet, and the both sides of magnetic core are provided with fin, the radiating
Heat emission hole is provided with piece, 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：Simple in construction, safe and convenient to use, the fin of use can effectively improve scattered
Thermal effect, the copper sheet of addition, the problem of can effectively solve the problem that transformer short-circuit, the setting of insulating trip can improve transformer and use
During stability.

Set in a kind of copper sheet type transformer as shown in Figure 1, including housing 1, magnetic core 2, coil 3 and copper sheet 4, housing 1
There is magnetic core 2, the upper and lower ends of magnetic core 2 are cased with copper sheet 4, and the outside of copper sheet 4 is provided with insulating trip 3, and the both sides positioned at magnetic core 2 are provided with
Heat emission hole 6 is provided with fin 5, fin 5, fin 5 is arranged on pedestal 7, and pedestal 7 is arranged in housing 1, on housing 1
Heat sink strip 8 is provided with, heat sink strip 8 is corresponding with heat emission hole 6, a segment distance, the cross section of magnetic core 2 are left between fin 5 and magnetic core 2
For octagon.
The beneficial effects of the invention are as follows：Simple in construction, safe and convenient to use, the fin of use can effectively improve scattered
Thermal effect, the copper sheet of addition, the problem of can effectively solve the problem that transformer short-circuit, the setting of insulating trip can improve transformer and use
During stability.
The above described is only a preferred embodiment of the present invention, being 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 model claimed of the invention
Enclose.
