Abstract
The invention discloses a transformer structure which comprises a box. A sealed separation cavity is arranged at the bottom inside the box, the top of the sealed separation cavity is provided with an inversely m-shaped three-phase three-column iron core, each core column is internally provided with an inner cavity, a cavity opening at the lower end of the inner cavity is arranged at the bottom of the iron core, the sealed separation cavity is internally provided with a through hole communicated with the cavity opening of the inner cavity of the core column, the sealed separation cavity is filled with magnetic fluid, the magnetic fluid fills the sealed separation cavity and then enters and fills the inner cavity of the core column, and the left side wall and the right side wall of the sealed separation cavity are connected with a plurality of cooling fins respectively. The transformer structure can achieve an iron core cooling effect, and the loss of the transformer is reduced.
Description
Technical field
The present invention relates to field transformer, specifically a kind of transformer device structure.
Background technology
Transformator is the device changing alternating voltage using the principle of electromagnetic induction, and it is by the coil on iron core, iron core
Winding is constituted, and can play the effect such as voltage transformation, current transformation, impedance conversion, isolation, voltage stabilizing.Prior art transformator is in work
When making, iron core temperature easily raises, and then leads to transformer loss to increase.
Content of the invention it is an object of the invention to provide a kind of transformer device structure, during solving the work of prior art transformator
The problem that iron core temperature easily raises.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of transformer device structure it is characterised in that: include casing, casing inner bottom part be provided with the closing being surrounded by Heat Conduction Material every
Chamber, is located at the three-phase three-column iron core that closing separate space top is provided with mountain font in casing, three stem stem upper end frames of iron core are provided with iron yoke,
It is wound with coil windings respectively on each stem stem, in each stem stem, is respectively provided with inner chamber, inner chamber lower end accent is arranged on iron core bottom
Portion, in described closing separate space, each accent position corresponding has the through hole connecting with stem stem inner chamber accent, in closing separate space
It has been filled with magnetic fluid, and magnetic fluid has been full of after closing separate space, enters back in stem stem inner chamber and is full of stem stem inner chamber, closes separate space
Left and right side wall is connected to multiple tracks fin, and fin passes from casing respective side wall respectively.
A kind of described transformer device structure it is characterised in that: the closing separate space tip position around mandrel bottom is additionally provided with
Sealing shroud, for sealing between mandrel bottom and closing separate space.
The stem stem of iron core is set to hollow, full of magnetic fluid in stem stem, using magnetic fluid and the common shape of iron core by the present invention
Become complete yoke, in the internal separate space with closing of stem stem, magnetic fluid communicates simultaneously, and when iron core temperature raises, heat is transferred to magnetic current
Body, can make magnetic current body heat content distribute by closing the fin of separate space side wall, and then can play the thermolysis to iron core, reduce
The loss of transformator.
Brief description
Fig. 1 is present configuration schematic diagram.

Close separate space 2, in casing 1, be located at the three-phase three-column iron core 3 that closing separate space 2 top is provided with mountain font, 3 three stem stem 4 upper ends of iron core
Erection has iron yoke 5, and each stem stem 4 is wound with coil windings 6 respectively, is respectively provided with inner chamber 7, inner chamber 7 lower end in each stem stem 4
Accent is arranged on iron core 3 bottom, and in closing separate space 2, corresponding each accent position is had and connected with stem stem 4 inner chamber accent
After through hole, has been filled with magnetic fluid 8 in closing separate space 2, and magnetic fluid 8 is full of closing separate space 2, enters back in stem stem 4 inner chamber 7 and fill
Full stem stem 4 inner chamber 7, closing separate space 2 left and right side wall is connected to multiple tracks fin 9, and fin 9 is respectively from casing 1 respective side
Wall passes.The closing separate space tip position of iron core 3 bottom periphery is additionally provided with sealing shroud 10, for sealing iron core 3 bottom and closing
Between separate space 2.
