Abstract
The utility model provides a distribution transformer ware body compact structure, including middle part compact heap, side compact heap, screw rod etc. The middle pressing cushion block adopts an arc shape which is tangent to the arc part of the coil and extends into the iron core. The two side pressing cushion blocks are also arc-shaped and extend outwards to exceed the screw rods beside the clamping pieces, so that the cushion blocks can effectively press the coil through the screw rods. After the novel distribution transformer body is used for compressing the cushion blocks, the contact area of the compression cushion blocks is increased obviously, the stability of the coil is further improved, the deformation is not easy, and the short-circuit resistance of the distribution transformer is enhanced.
Description
Technical Field
The utility model relates to a distribution transformer field, concretely relates to distribution transformer ware body compact structure.
Background
The current used pressing cushion block of the body of the distribution transformer is rectangular laminated wood, and the middle pressing cushion block is only slightly wider than the width of a clamping piece and is less in contact with the end face of a coil. The two side pressing cushion blocks can only press a small part of the end face of the coil, and the stress on the end face of the coil is unbalanced when the side pulling screw rod is fastened, so that the coil cannot be pressed tightly. Nowadays, the requirement of the national grid on short circuit resistance of the distribution transformer is more and more strict, the contact between the compression cushion block and the end face of the coil is smaller, and the requirement of the national grid on short circuit resistance cannot be met.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a distribution transformer ware body compact structure, the stability of coil further improves, and non-deformable has strengthened distribution transformer's anti short circuit's ability.
The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:
a distribution transformer body pressing structure comprises a middle pressing block, side pressing blocks, coils and screws, wherein the inner edge of the middle pressing block is shorter than the outer edge, the part of the side edge, close to the inner edge, is arc-shaped and is in contact with the arc-shaped part of the coil, the inner edge extends into the coil, and screw holes are formed in the middle of the middle pressing block, close to the outer edge; the inner edge of the side compressing block is arc-shaped and is in contact with the arc part of the coil; the screw rod passes through a screw rod hole of the middle pressing block.
Preferably, screw holes are formed in two sides, close to the outer edge, of the side compression blocks.
Preferably, the inner side surface of the middle pressing block is in a step shape and is tightly attached to the iron core to penetrate into the iron core.
The utility model has the advantages that: the novel distribution transformer body compresses tightly backing plate structure, has effectively increased the lifting surface area of cushion and coil tip to make cushion and coil tip atress more even, strengthened the anti axial deformation's of coil ability, effectively strengthened the stability of coil.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a distribution transformer ware body compact structure, includes middle part compact heap 1, side compact heap 3, iron core 4, coil 5, screw rod 2, limit weak point in the outside in middle part compact heap 1, the side is close to the part on the limit and is arc and 5 arc portions of coil and pastes eagerly, and middle part compact heap 1 middle part is close to the outside and is provided with the screw rod hole, and the echelonment is personally submitted with iron core 4 in the 1 interior limit of middle part compact heap, and it is inside deep into iron core 4 to closely laminate with iron core 4. The inner side of the side compressing block 3 is arc-shaped and is attached to the arc part of the coil 5, and the side compressing block 3 extends outwards to exceed the screw rod 2 beside the clamping piece, so that the cushion block can effectively compress the coil 5 through the screw rod 2. The stability of the coil 5 is further improved, the coil is not easy to deform, and the short-circuit resistance of the distribution transformer is enhanced.
