Abstract
The invention discloses a transformer core upper part positioning structure which comprises an oil tank, a core in the oil tank, a clamp piece for fixing the core, a top beam on the clamp piece, an oil tank cover above the top beam, a positioning shaft welded on the top beam and penetrating through the oil tank cover, and a flange welded on the oil tank cover, wherein a fixing plate for fixing the positioning shaft is arranged in the flange. In the transformer core upper part positioning structure, an insulating member is fixed by a special device with a novel structure to realize reliable insulation among the core, the clamp piece and the oil tank and realize close fit, thus the service life of the transformer is prolonged; and moreover, the units are effectively separated and led to the outer part and reliably connected respectively to facilitate the field insulating measurement and fault analysis.
Description
Technical field
The present invention relates to a kind of transformer, be specifically related to a kind of transformer core top location structure.
Background technology
In the prior art, transformer top location structure adopts the location tight fixed bolt directly to be screwed on the fuel tank cap surely on the back timber of the side of staying, because fuel tank, folder, iron core and location tight fixed bolt are metal material, is prone to take place electric conduction phenomena, easy breaking out of fire.In addition, owing to directly locate with the location tight fixed bolt, loosening phenomenon takes place in the long-distance transportation meeting, causes internal structure unstable, and suitable is dangerous, and also shorten greatly useful life.
Summary of the invention
The object of the present invention is to provide the transformer core top location structure of a kind of Stability Analysis of Structures, insulation, long service life.
Technical scheme of the present invention is: a kind of transformer core top location structure; Comprise folder, the back timber on the folder, the back timber top of iron core in the fuel tank, fuel tank, fixed iron core fuel tank cap, be welded in the locating shaft that passes fuel tank cap on the back timber and be welded in the flange on the fuel tank cap, be provided with the fixed head of a stationary positioned axle in the described flange.
In preferred embodiment of the present invention, described fixed head is fixed through the location tight fixed bolt.
In preferred embodiment of the present invention, said fixed head is an epoxy plate.
According to the invention is a kind of transformer core top location structure; Isolated plant fixed insulation spare through new structure; Realize the reliable insulation between iron core, folder, fuel tank and reach closely cooperating, thereby increase the useful life of transformer, in addition; Effectively separate each unit and cause outside reliable contact respectively, be convenient to in-site measurement insulation, accident analysis.

Each mark is following in the accompanying drawing: 1, fuel tank, 2, iron core, 3, folder, 4, back timber, 5, fuel tank cap, 6, locating shaft, 7, flange, 8, fixed head, 9, the location tight fixed bolt.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
According to the invention is a kind of transformer core top location structure; As shown in Figure 1: comprise folder 3, the back timber 4 on the folder 3, back timber 4 tops of iron core 2 in the fuel tank 1, fuel tank 1, fixed iron core 2 fuel tank cap 5, be welded in the locating shaft 6 that passes fuel tank cap 5 on the back timber 4 and be welded in the flange 7 on the fuel tank cap 5; Be provided with the fixed head 8 of a stationary positioned axle 6 in the flange 7, fixed head 8 is an epoxy plate.
Be illustrated in figure 2 as flange 7 inner structure vertical views, comprise outermost flange 7, closely be embedded in fixed head 8 and the locating shaft 6 in the fixed head 8 in the flange 7, fixed head 8 is fixed on the fuel tank cap 5 through location tight fixed bolt 9.
Epoxy plate has good insulating, effect that mechanical strength is high, can play a well tight fixed effect, is not easy to damage.
Flange and fixed head closely cooperate, and form the flange arrangement of sealing, make locating shaft firm.
According to the invention is a kind of transformer core top location structure; Isolated plant fixed insulation spare through new structure; Realize the reliable insulation between iron core, folder, fuel tank and reach closely cooperating, thereby increase the useful life of transformer, in addition; Effectively separate each unit and cause outside reliable contact respectively, be convenient to in-site measurement insulation, accident analysis.
The above is merely embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed; Variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range that claims were limited.
