Abstract
The utility model relates to an improved structure of a finned radiator oil collecting tube for a large transformer, consisting of an oil collecting tube, oil flow holes of box sheets distributed on the oil collecting tube, and a flange, wherein the original Phi 89mm oil collecting tube is changed into a Phi 140mm oil collecting tube; the original oil flow holes of the box sheets with two discontinuous holes is changed the original two discontinuous holes into the oil flow holes of the box sheets with the continuous hole; and the flange and the oil collecting tube form the improved structure of the finned radiator oil collecting tube for the large transformer. The improved structure of the finned radiator oil collecting tube for the large transformer has the advantages that the diameter of the pipeline is increased, so that the pipeline can contain more oil, the mechanical strength is good, the number of box sheets of radiating fins is increased, and the radiating area is increased. The area where the oil collecting tube leads to the oil flow holes of the box sheets is increased, so as to effectively enhance hot oil circulation. The resistance of oil is reduced, and the flow of oil is accelerated, so as to lead the radiating efficiency to be improved.

The utility model content
The technical problems to be solved in the utility model, it is big to provide a kind of volume, and the big resistance of oil flow hole area is little, accelerates oil flow, effectively impels Circulation and Hot Oil Spray, and the high-power transformer gilled radiator oil collecting pipe that radiating efficiency is high improves structure.
The technical scheme that adopts is:
High-power transformer gilled radiator oil collecting pipe improves structure, is made up of oil collecting pipe, box sheet oil flow hole and the flange laid on oil collecting pipe.Described oil collecting pipe is modified into ф 140mm oil collecting pipe with former ф 89mm oil collecting pipe, described box sheet oil flow hole is modified into a continuous hole with former discontinuous two holes composition and forms, flange and oil collecting pipe welding constitute high-power transformer gilled radiator oil collecting pipe and improve structure.
Above-mentioned flange is the square four hole flanges of standard, and its flange and oil collecting pipe constitute the square four hole oil collecting pipe structures of taper reducing by the welding of taper reducer pipe.
Above-mentioned flange is the square four hole flanges of standard, and its flange and oil collecting pipe constitute the square four hole oil collecting pipe structures of reducing by the reducer pipe welding.
Above-mentioned flange is standard circular four hole flanges, and its flange and oil collecting pipe constitute the circular four hole oil collecting pipe structures of taper reducing by the welding of taper reducer pipe.
Above-mentioned flange is standard circular four hole flanges, and its flange and oil collecting pipe constitute the circular four hole oil collecting pipe structures of reducing by the reducer pipe welding.
Above-mentioned flange is standard circular six hole flanges, and its flange and oil collecting pipe constitute the circular six hole oil collecting pipe structures of taper reducing by the welding of circular cone reducer pipe.
Above-mentioned flange is standard circular six hole flanges, and its flange and oil collecting pipe constitute the circular six hole oil collecting pipe structures of reducing by the reducer pipe welding.
Above-mentioned flange is circular six hole flanges, and its flange and oil collecting pipe directly weld and constitute circular six hole oil collecting pipe structures.
The utility model adopts ф 140mm pipe as radiator upper and lower oil collecting pipe advantage to be:
Charge of oil was many after a, pipeline diameter increased, and mechanical strength is good, and fin box sheet is increased, and area of dissipation increases.
The oil flow hole area that b, oil collecting pipe lead to the box sheet increases, and effectively impels Circulation and Hot Oil Spray.
The resistance of C, oil reduces, and accelerates flowing of oil, and radiating efficiency is improved.
