Utility model content
For above-mentioned problems of the prior art, the utility model provides a kind of oil-immersed transformer folder, system
Make it is simple, it is at low cost, good fixing effect and radiate convenient for iron core.
To achieve the goals above, the technical scheme adopted by the utility model is that:
A kind of oil-immersed transformer folder, including upper clamping piece and lower clamping piece, wherein
The upper clamping piece is U-type groove made of steel plate bending, and the upper clamping piece slot bottom is upward, to setting before and after two vertical planes
Multiple outside L-type upper junction plates are set and be welded with, plunger position is corresponded on the slot bottom and is opened up there are three thermovent, the slot
The quadrangle at bottom, which has, cuts on slot bottom and bends upward lifting plate, the hole for hoist of oriented outer openings on the lifting plate；
The lower clamping piece be two U-shaped risers and a U-shaped bottom slot integrated formed structure, the U-shaped bottom slot slot bottom to
Under, two vertical planes front and back of the U-shaped bottom slot is to setting and the corresponding upper junction plate is equipped under multiple outside L-types and connects
Plate, is transversely provided with clamping structure in the middle part of the U-shaped riser inner sidewall, and the clamping structure is equipped with multiple through U-shaped riser
Screw hole.
The length of the clamping structure is equal to U-shaped riser width.
The length of the clamping structure is greater than before and after winding to diameter and both ends are equipped at least two screw holes.
Through-hole is equipped on the upper junction plate and lower connecting plate.
A plurality of reinforcing rib is transversely provided on the U-shaped riser inner sidewall.
Between the lifting plate and upper clamping piece slot bottom, between upper junction plate and upper clamping piece vertical plane, lower connecting plate and U-shaped bottom
It is welded with triangle between slot vertical plane and reinforces iron.
Compared with the prior art, the upper and lower folder of the utility model is formed by one piece of steel plate bending, and production is simple.Wherein,
The thermovent that upper clamping piece opens up not only increases the logical path of oil stream, reinforces heat dissipation, and the steel plate cut down can be used for
It is processed into reinforcing rib, reinforces iron and upper and lower connecting plate, increase material availability, reduce rolled steel dosage, save the cost, in addition,
It is mobile convenient for transformer equipped with lifting plate, and lifting plate is that cutting is bent, easy to process, the rectangular opening generated after bending
Equally play the role of heat dissipation；Lower clamping piece is equipped with clamping structure, can fix between U-shaped riser and coil certain thickness
Support board prevents coil from deforming outward or left right shift, meanwhile, it can be connected by clamping screw between the clamping structure of two sides
It connects, plays the role of further being fixedly clamped to transformer.
