Abstract
The invention discloses a kind of large-scale dry-type transformer iron core feet, the iron core is supported in feet, and the feet includes pedestal and cushion block, and cushion block is supported on pedestal；The cushion block includes an ontology, the support slot with bottom surface and two sides is equipped on cushion block, the bottom surface of the support slot is horizontal plane, and two sides are inclined outwardly, several positioning table terraces are equipped in each side higher slice of support slot, the bottom surface of iron core is supported on the positioning table terrace of support slot.The strict sturdy gap between footing and iron core of the present invention, strengthens the stability of large-scale iron core, unloaded noise can be greatly lowered, optimize transformer.
Description
Technical field：
The present invention relates to a kind of large-scale dry-type transformer iron core feets.
Background technology：
Existing conventional core feet, be by DMC in mold injection-compression molding.The feet 1 of this structure is due to iron core 2 at different levels
Lengthy motion picture width is different, so institute's pad position is only capable of including 2 primary portion of iron core, such as Fig. 1 causes many chip levels that can not fix, shadow
Ring zero load noise.
Invention content：
The present invention is to provide a kind of large-scale dry-type transformer iron core feet to solve the above-mentioned problems of the prior art.
The technical solution adopted in the present invention has：A kind of large size dry-type transformer iron core feet, the iron core are supported in pad
On foot, the feet includes pedestal and cushion block, and cushion block is supported on pedestal；The cushion block includes an ontology, is equipped on cushion block
The bottom surface of support slot with bottom surface and two sides, the support slot is horizontal plane, and two sides are inclined outwardly, in the every of support slot
A side higher slice is equipped with several positioning table terraces, and the bottom surface of iron core is supported on the positioning table terrace of support slot.
Further, the bottom surface of the cushion block is equipped with locating slot, is equipped on pedestal compatible with the locating slot
Positioning table.
Further, by forming one after resin solidification between the iron core and cushion block.
Further, the cushion block is made of liquid room temperature resin mixing silicon powder glass fiber tape normal temperature cure.
The present invention has the advantages that：
The strict sturdy gap between footing and iron core of the present invention, strengthens the stability of large-scale iron core, can significantly drop
Low no-load noise optimizes transformer.
Description of the drawings：
Fig. 1 is the structure chart of iron core feet in the prior art.
Fig. 2 is the structure chart of the present invention.
Fig. 3 is the structure chart of cushion block in the present invention.
Specific implementation mode：
The present invention will be further described below with reference to the drawings.
As shown in Figures 2 and 3, a kind of large-scale dry-type transformer iron core feet of the present invention, the iron core 2 are supported in feet
On, feet includes pedestal 11 and cushion block 12, and cushion block 12 is supported on pedestal 11, and iron core 2 is supported on cushion block 12, iron core and cushion block
By forming one after resin solidification between 12.
Cushion block 12 includes an ontology, and the support slot 121 with bottom surface and two sides, support slot 121 are equipped on cushion block 12
Bottom surface be horizontal plane, two sides are inclined outwardly, and several positioning table terraces are equipped in each side higher slice of support slot 121
122, the bottom surface of iron core is supported on the positioning table terrace 122 of support slot 121.Positioning table terrace 122 realizes the branch of iron cores at different levels
Support.
Locating slot 123 is equipped on the bottom surface of cushion block 12, it is compatible with the locating slot 123 fixed to be equipped on the pedestal 11
Position platform 111.
Cushion block 12 is made of liquid room temperature resin mixing silicon powder glass fiber tape normal temperature cure, effectively reinforces iron core branch
Support reduces transformer noise.
In use, cushion block 12 is filled between iron core 2 and pedestal 11, by resin solidification between iron core and cushion block 12, Gu
Real iron cores at different levels can be supportted after change.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as the present invention's
Protection domain.
