Description
Technical field
The present invention relates to field of electrical equipment, especially, is related to a kind of power transformer.
Background technology
A kind of more basic power transformer of oil-filled transformer；Its iron core is immersed in the transformer oil full of transformer shell
In, have insulation and conductive force concurrently.By the Effect of Nature Convection of transformer oil, heat caused by iron core can effectively be passed
It is delivered on the fin of transformer case, and outwardly loss.However, because current transformer oil is quiet in transformer shell
Only, Effect of Nature Convection is relatively limited, and heat transference efficiency is limited by larger, so as to limit the specified appearance of transformer
Amount.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of magnetic to move heat radiating type transformer, the magnetic moves heat radiating type and become
Depressor can internally form forced convertion, have higher radiating efficiency.
The technical solution adopted for the present invention to solve the technical problems is：The magnetic, which moves heat radiating type transformer, includes transformer
Shell, iron core, and be wound on iron core primary, secondary windings；The iron core is immersed in the transformer oil in transformer shell；
Non-magnetic straight tube is fixed with the iron core；One section of electromagnet for being provided with axis hole, and an irony are fixed with the straight tube
Sliding block；The irony sliding block is connected to the end of straight tube by extension spring；During the electromagnet power down, the irony sliding block and electromagnetism
A segment distance is left between body；When the electromagnet is powered, the irony sliding block is drawn to electromagnet under magnetic attraction effect
End；Also around power taking winding is equipped with the iron core, the power taking winding after an on-off circuit module by exporting to the electricity
Magnet；The on-off circuit module switches on and off power taking winding and electromagnet by the fixed cycle.
Preferably, the on-off circuit module, which is a square wave, occurs module, high level and low level are alternately exported,
When exporting high level, that is, the electromagnet is remained up, when exporting low level, i.e., output is zero, that is, causes the electromagnetism
Body remains open.
Preferably, the both ends of the straight tube are respectively equipped with circulating direction identical check valve, and the direction of check valve from
The electromagnet points to the irony sliding block；Gap is left between the irony sliding block and straight tube；So that when electromagnet is powered,
Irony sliding block can slowly be attracted to electromagnet, and now, the transformer oil between irony sliding block and electromagnet is slided by irony
Gap between block and straight tube is flowed between irony sliding block and the extension spring, and the transformer oil inside and outside straight tube is substantially not without exchange；
And during electromagnet dead electricity, irony sliding block resilience, the transformer oil inside and outside straight tube can be along the circulation of the check valve
Flow in direction；So as to realize that the one-way circulation of the transformer oil inside and outside straight tube flows, compared to the convection current of reciprocating vibrating type, convection current
Range of DO and path are bigger, more conducively take the heat of iron core on the outside of transformer to.
The beneficial effects of the present invention are：Discontinuity magnetic attraction by the electromagnet to the irony sliding block, can make
The straight tube in irony sliding block it is of reciprocating vibration under the constraint of extension spring, it is strong so as to promote transformer oil inside and outside straight tube to carry out
Convection current processed, largely promote the radiating efficiency of transformer core.
Brief description of the drawings
Fig. 1 is the structural representation that this magnetic moves heat radiating type transformer embodiments one.
Fig. 2 is the structural representation that this magnetic moves heat radiating type transformer embodiments two.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples：
Embodiment one：
In the embodiment one shown in Fig. 1, the magnetic, which moves heat radiating type transformer, includes transformer shell, iron core 1, and is wound on iron core
On armature winding 2, secondary windings 3；The iron core 1 is immersed in the transformer oil in transformer shell；It is fixed on the iron core 1
There is non-magnetic straight tube 4；One section of electromagnet for being provided with axis hole 5, and an irony sliding block 6 are fixed with the straight tube 4；The iron
Matter sliding block 6 is connected to the end of straight tube 4 by extension spring 7；During 5 power down of electromagnet, the irony sliding block 6 and electromagnet 5 it
Between leave a segment distance；When the electromagnet 5 is powered, the irony sliding block 6 is drawn to the end of electromagnet 5 under magnetic attraction effect
Portion；Also around power taking winding 8 is equipped with the iron core 1, the power taking winding 8 after an on-off circuit module 9 by exporting to described
Electromagnet 5；The on-off circuit module 9 switches on and off power taking winding 8 and electromagnet 5 by the fixed cycle.
Above-mentioned magnetic moves heat radiating type transformer, and the on-off circuit module 9 is that module occurs for a square wave, is alternately exported
High level and low level, when exporting high level, that is, the electromagnet 5 is remained up, when exporting low level, i.e. output is
Zero, that is, the electromagnet 5 is remained open.The ready-made article that module occurs for square wave is more, and cost is relatively inexpensive；Such as, rectification is filtered
Ripple module concatenates with copped wave module forms a square wave generation module；Specific constructive form repeats no more.
The dynamic heat radiating type transformer of above-mentioned magnetic, the discontinuity magnetic attraction by the electromagnet 5 to the irony sliding block 6,
The irony sliding block 6 in the straight tube 4 that can make is of reciprocating vibration under the constraint of extension spring 7, so as to promote the transformer inside and outside straight tube 4
Oil vibrates back and forth, forms forced convertion, largely promotes the radiating efficiency of transformer core 1.
Embodiment two：
For the embodiment two shown in Fig. 2, unlike embodiment one, the both ends of the straight tube 4 are respectively equipped with circulating direction
Identical check valve 10a, 10b, and the irony sliding block is pointed in check valve check valve 10a, 10b direction from the electromagnet 5
6；Gap is left between the irony sliding block 6 and straight tube 4；So that electromagnet 5 be powered when, irony sliding block 6 can slowly by
Electromagnet 5 is drawn to, now, transformer oil between irony sliding block 6 and electromagnet 5 is by between irony sliding block 6 and straight tube 4
Clearance flow enters between irony sliding block 6 and the extension spring 7, and the transformer oil inside and outside straight tube 4 is substantially not without exchange；And lost in electromagnet 5
Electricity, during the resilience of irony sliding block 6, the transformer oil inside and outside straight tube 4 can be along described check valve 10a, 10b circulating direction
Flowing；So as to realize that the one-way circulation of the transformer oil inside and outside straight tube 4 flows, compared to the convection current of reciprocating vibrating type, convection current follows
Ring scope and path are bigger, more conducively take the heat of iron core on the outside of transformer to.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification for being made, equivalent substitution, it should be included in the scope of the protection.
