Abstract
The invention discloses a kind of transformer device structures, its iron core include two stand to c-type iron-core workpiece, between the c-opening top of two c-type iron-core workpieces, it is separately connected integrally between lower part and has lateral connection body, it is connected with vertical connector vertically between two lateral connection bodies, primary coil is wrapped on the c-type vertical portion of two c-type iron-core workpieces, and the secondary coil of transformer is wrapped on vertical connector.The present invention cooperates integrated iron core to use silicon steel sheet overlaying structure, and the eddy-current loss in transformer core can be effectively reduced.
Description
Technical field
The present invention relates to field transformer, specifically a kind of transformer device structure.
Background technique
Transformer iron loss refers to the power consumed in the core when transformer secondary coil open circuit, including excitation loss and whirlpool
Stream loss, wherein eddy-current loss is affected.The prior art uses the mode of multiple silicon steel sheet superpositions that iron core is made to reduce whirlpool
Stream loss, but silicon steel sheet superposition processing technology is complicated, also designs not over core structure and reduces eddy-current loss.
The object of the present invention is to provide a kind of transformer device structures for summary of the invention, to solve to be vortexed in prior art transformer
Big problem is lost.
In order to achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of transformer device structure, it is characterised in that: its iron core include two stand to c-type iron-core workpiece, two c-type iron-core workpieces
C-opening direction it is identical, between the c-opening top of two c-type iron-core workpieces, be separately connected between lower part and integrally have lateral connection
Body has been integrally connected vertical connector between two lateral connection body middle positions vertically, and the primary coil of transformer is wrapped in two C
On the c-type vertical portion of sections core, the secondary coil of transformer is wrapped on vertical connector.
A kind of transformer device structure, it is characterised in that: insertion is equipped between the c-type vertical portion of two c-type iron-core workpieces just
The exhausted magnetic ceramic member of insulation in grade coil, and insulate exhausted magnetic ceramic member and primary coil close contact.
A kind of transformer device structure, it is characterised in that: the lateral cross-sectional area of the vertical connector is equal to two c-type iron
The sum of c-type vertical portion lateral cross-sectional area of core.
A kind of transformer device structure, it is characterised in that: integrated iron core structure is made of silicon steel sheet superposition.
In the present invention, armature winding is wound on the c-type vertical portion of two c-type iron-core workpieces, and two c-type vertical portion sectional areas are identical,
For the vertical connector sectional area half where secondary windings, core portion where armature winding is designed as separated structure, and existing
Core portion where having technology armature winding is that the structure of monoblock type is compared, and under the identical requirement of transformer performance, can be reduced
Eddy-current loss at armature winding, cooperation integrated iron core use silicon steel sheet overlaying structure, can be effectively reduced in transformer core
Eddy-current loss.

Fig. 2 is core portion structural schematic diagram of the present invention.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of transformer device structure, iron core include two stand to c-type iron-core workpiece 1, two c-type iron cores
The c-opening direction of body 1 is identical, between the c-opening top of two c-type iron-core workpieces 1, is separately connected between lower part and integrally has transverse direction
Connector 2 has been integrally connected vertical connector 3, the primary coil 4 of transformer between two lateral connection bodies, 2 middle position vertically
It is wrapped on the c-type vertical portion 5 of two c-type iron-core workpieces 1, the secondary coil 6 of transformer is wrapped on vertical connector 3.
The exhausted magnetic ceramic member 7 of insulation being equipped between the c-type vertical portion of two c-type iron-core workpieces 1 in insertion primary coil 4, and absolutely
The exhausted magnetic ceramic member 7 of edge is in close contact with primary coil 4, is played a supporting role to primary coil 4, and just secondary coil vibration is prevented.
The lateral cross-sectional area of vertical connector 3 is equal to the sum of 5 lateral cross-sectional area of c-type vertical portion of two c-type iron-core workpieces 1.
Integrated iron core structure is made of silicon steel sheet superposition.
