Abstract
The utility model discloses an accessory of a transformer, in particular to a box edge structure of a transformer with a folded edge. The box edge structure of the transformer with the folded edge comprises a box edge which is welded on a box wall. The box edge structure is characterized in that one side of the box edge which is welded with the box wall is bended to be the shape of step, a groove is formed between the box edge and the box wall, the groove is internally put with a seal strip, and the upper surface of the box edge is parallel with the top end of the box wall. The box edge of the box edge structure of the transformer with the folded edge does not need to be welded with a limiting metal strip; and the upper surface of the box edge is tightly combined with the box cover after the box edge is tightly fixed with the box cover, so that the seal strip is positioned in the environment which is approximately to be sealed, and the seal strip can not move any longer. Therefore, the box edge structure has the functions of dust resisting and light shading, reduces the possibility that the seal strip is contacted with the air, and improves the sealing performance of the transformer.
Description
(1) technical field
The utility model relates to a kind of transformer accessory, and particularly a kind of have the transformer tank of flanging along structure.
(2) background technology
At present, middle-size and small-size oil tank of transformer case is along using flat plate usually, and case is along the last welded limiting bonding jumper that needs, the case edge is fastening with case lid behind the placement sealing strip with bolt, the sealing strip stress deformation, the force reaction that distortion produces reaches sealing effectiveness in case edge and case lid.In fastening process, although bolt has certain position-limiting action, sealing strip still can produce displacement, has weakened the power that acts on case lid and case edge.Sealing strip contacts with air and can accelerate aging speed simultaneously, and these factors all can cause the transformer sealing to descend, and is unfavorable for transformer operation steady in a long-term.
(3) summary of the invention
The utility model is in order to remedy the defective of prior art, provide a kind of prevent that sealing strip from moving and the transformer tank that flanging is arranged that wears out along structure.
The utility model is achieved by the following technical solution:
A kind of have the transformer tank of flanging along structure, comprise the case edge that is welded on the tank wall, it is characterized in that: it is stepped that case is converted into single order along the lateral bending with the tank wall welding, forms groove between case edge and the tank wall, be placed with sealing strip in the groove, case flushes along upper surface and tank wall top.
The beneficial effects of the utility model are: this transformer tank that flanging is arranged is along structure, case along on need not the welded limiting bonding jumper, case is along combining closely with case lid fastening back upper surface and case lid, sealing strip is in the approximate airtight environment, sealing strip no longer produces displacement, have dustproof, the effect of shading, reduce the possibility that sealing strip contacts with air simultaneously, improved the sealing of transformer.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 has the structural representation of the transformer tank of flanging along structure for the utility model.
Accompanying drawing 2 is the A place structure for amplifying schematic diagram of Fig. 1.
Among the figure, 1 case edge, 2 tank walls, 3 sealing strips, 4 case lids, 5 grooves.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This transformer tank that flanging is arranged is along structure, comprise that the case that is welded on the tank wall 2 along 1, is characterized in that: to be converted into single order stepped with a lateral bending of tank wall 2 welding along 1 for case, case along 1 with tank wall 2 between formation groove 5, be placed with sealing strip 3 in the groove 5, case flushes along 1 upper surface and tank wall 2 tops.
This transformer tank that flanging is arranged is along structure, case forms groove 5 along 1 with tank wall 2 welding backs, when with case along 1 with case lid 4 by after the bolted, sealing strip 3 is arranged in groove 5 and is in approximate airtight environment, can not produce displacement, reduced the possibility that sealing strip 3 contacts with air simultaneously, prevented to wear out.Can make the step size of case along 1 according to the size of sealing strip 3, make the big or small suitable of the size of groove 5 and sealing strip 3, can strengthen result of use.
Claims (1)
1. the transformer tank that flanging is arranged is along structure, comprise that the case that is welded on the tank wall (2) is along (1), it is characterized in that: it is stepped that the lateral bending that case welds along (1) and tank wall (2) is converted into single order, case forms groove (5) between (1) and tank wall (2), be placed with sealing strip (3) in the groove (5), case flushes along (1) upper surface and tank wall (2) top.
