For example, Chinese patent file CN201629198U discloses a kind of corrugation oil duct of transformer insulated heat transmission, and it is to be the insulating board of 1-2mm with thickness, processes the corrugated structure of type with the Corrugating Machine roller.During the coiling transformer coil it is put into the suitable position of coil, in coil, forms the oil duct path of heat radiation, the heat that in the transformer running coil is produced is taken away, and has reduced the temperature rise of coil.But this insulation board has the problem of aforesaid radiating effect difference.
For addressing the above problem, Chinese patent file CN101477880A discloses a kind of transformer double surface density type heat radiation oil duct insulation board for high-low voltage windings.It adopts insulating board to make; By base plate, close apart from insulation strip group and the thin transformer double surface density type heat radiation oil duct insulation board for high-low voltage windings that constitutes apart from the insulation strip group, this transformer has rationally used close apart from insulation strip group and thin apart from the insulation strip group, has guaranteed the oil duct distance between the winding; It has arrived certain positive role to the transformer heat radiation; But this insulation board is vertically heat extraction still, and laterally oil duct is isolated through insulation board, and its radiating effect is relatively poor.
The utility model content
For this reason, the utility model technical problem to be solved is, a kind of oil-filled transformer of good heat dissipation effect is provided.
For solving the problems of the technologies described above, a kind of oil-filled transformer of the utility model, it comprises fuel tank; The device body, it places said fuel tank internal, and said device body comprises iron core; And be wrapped in low pressure winding and the high pressure winding on the said iron core; Isolated through a corrugation insulation board between said low pressure winding and the high pressure winding, the plate face of said corrugation insulation board is provided with a plurality of louvres, and said louvre is communicated with said high pressure winding and low pressure winding.
Said louvre is provided with perpendicular to the plate face of said corrugation insulation board, and is uniformly distributed on the plate face of said corrugation insulation board, and the aperture of its louvre is 2-4mm.
The device body bottom of said transformer is provided with damping, and said device body connects with said fuel tank bottom through damping.
Said damping is the spring that is arranged at four corners of said device body bottom, and an end of said spring is fixedly connected with said device body bottom, and its other end is with said fuel tank pig.
The technique scheme of the utility model is compared prior art and is had the following advantages:
(1) insulation adopts the surface to be with the ripple type insulation board of micropore between the high and low pressure coil; Not only can make current downflow on the transformer oil; Flow about all right, guarantee that like this oil duct is unimpeded between coil mechanical strength and the high and low pressure coil, radiating effect is more outstanding.
(2) the device body of said transformer bottom is provided with damping, guarantees that device is not unsettled in fuel tank, and suitable activity space is arranged, and relaxes to reduce product active force between device body and the fuel tank in transportation, and product reduces noise effectively in operation.
Description of drawings
For the content that makes the utility model is more clearly understood,, the utility model is done further detailed explanation, wherein below according to the specific embodiment of the utility model and combine accompanying drawing
