The purpose of this utility model is, provides a kind of transformer special-purpose strong oily circulator, to solve the problems of the technologies described above.
In order to solve the problems of the technologies described above, by the following technical solutions:
The special-purpose strong oily circulator of a kind of transformer is characterized in that: comprise housing, be located at stator and rotor in the housing, described stator is provided with stator winding, and the outer wall of described housing is provided with terminal box; The front end of described housing is fixedly connected with front end housing, and the center of front end housing is provided with the fore bearing chamber, and the front side of front end housing is fixedly connected with forward flange; The rear end of described housing is fixedly connected with rear end cap, and the center of rear end cap is provided with the rear bearing chamber, and the rear side of rear end cap is fixedly connected with rear flange; Described inner surface of stator is provided with the housing that adopts non magnetic corrosion resistant metal thin plate to make, and the two ends of described housing are sealedly and fixedly connected with front end housing, rear end cap respectively; Described rotor is arranged in the housing, employing be the cast-in aluminum squirrel cage rotor, the armature spindle inner hollow is provided with impeller in the armature spindle inner chamber; Be connected by fore bearing between the front end of described armature spindle and the fore bearing chamber, be connected by rear bearing between the rear end of armature spindle and the rear bearing chamber; Described forward flange and rear flange all are the I shape flanges, and their center all is provided with the through hole that the inner chamber with armature spindle connects.
Say further, be provided with preceding sealing ring between described forward flange and the front end housing; Be provided with the back sealing ring between described rear flange and the rear end cap.
The utility model is the assembly that adopts shield electric machine and impeller, has little, in light weight, the hermetically sealed ne-leakage of volume, energy consumption is little, efficient is high, effective, advantage that structure is new and easy for installation, has solved the circulation transportation problem of transformer oil heat radiation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, the special-purpose strong oily circulator of transformer described in the utility model comprises housing 6, is located at stator 13 and rotor 16 in the housing 6, described stator 13 is provided with stator winding 14, the outer wall of described housing 6 is provided with terminal box 7, and terminal box 7 uses aviation plug to connect, and disconnects conveniently.
The front end of described housing 6 is welded with front end housing 5, the center of front end housing 5 is provided with fore bearing chamber 3, the front side of front end housing 5 is provided with forward flange 1, described forward flange 1 is fixedly mounted on the front end housing 5 by hexagon socket head cap screw, and, between forward flange 1 and front end housing 5, also be provided with the preceding sealing ring 4 of oil resistant.The rear end of described housing 6 is welded with rear end cap 8, the center of rear end cap 8 is provided with rear bearing chamber 10, and the rear side of rear end cap 8 is provided with rear flange 12, and described rear flange 12 is fixedly mounted on the rear end cap 8 by hexagon socket head cap screw, and, between rear flange 12 and rear end cap 8, be provided with back sealing ring 9.
The inner surface of described stator 13 is provided with the housing 15 that adopts non magnetic corrosion resistant metal thin plate to make, and the two ends of described housing 15 are sealedly and fixedly connected with front end housing 5, rear end cap 8 respectively.So, transformer oil and stator winding 14 are isolated fully, thereby avoid influencing the quality of transformer oil and the useful life of transformer because electronics winding 14 burns out discharge.
Described rotor 16 is arranged in the housing 15, employing be the cast-in aluminum squirrel cage rotor, the armature spindle inner hollow is provided with impeller 18 in the armature spindle inner chamber.Be connected by fore bearing 2 between the front end of described armature spindle and the fore bearing chamber 3, be connected by rear bearing 11 between the rear end of armature spindle and the rear bearing chamber 10.Described forward flange 1 and rear flange 12 all are the I shape flanges, and their center all is provided with the through hole that the inner chamber with armature spindle connects.When the recirculation cooler energising, during rotor 16 rotations, transformer oil is realized the circulation of transformer oil from the transformer body to the heat abstractor under the axial promotion of impeller 18, thereby reaches the purpose to the transformer body fast cooling.Impeller 18 is made the covering of the fan shape, even recirculation cooler is not worked, transformer oil also can be smoothly by the heat radiation of impeller 18 natural circulation.
