Description
Technical field
The present invention relates to the special-purpose strong oily circulator of a kind of transformer, belong to the transformer Cooling technical field.
Background technology
Transformer is in running, and the heat that useless power consumption produces can cause the temperature of transformer oil to raise.At present, the cooling mode of cooling general employing forced oil-circulation wind of Large and Medium-sized Power Transformer, DC traction transformer and furnace transformer etc., and extensively adopted the main accessories of strong oily this class transformer of circulation forced air cooler.But the circulation transportation problem of transformer oil from the transformer body to the heat abstractor still is not well solved.
Summary of the invention
The object of the invention is to, provide 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:

Say further, be provided with front sealing ring between described forward flange and front end housing; Be provided with rear sealing ring between described rear flange and rear end cap.
The present invention is the assembly that adopts shield electric machine and impeller, has advantages of that volume is little, lightweight, Full-sealed non-seepage leaks, energy consumption is little, efficient is high, effective, 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 invention.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, the special-purpose strong oily circulator of transformer of the present invention comprises housing 6, is located at stator 13 and rotor 16 in 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 front end housing 5 by hexagon socket head cap screw, and, also be provided with the front sealing ring 4 of oil resistant between forward flange 1 and front end housing 5.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 rear end cap 8 by hexagon socket head cap screw, and, sealing ring 9 after being provided with between rear flange 12 and rear end cap 8.
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 affecting the quality of transformer oil and the useful life of transformer because electronics winding 14 burns out discharge.
Described rotor 16 is arranged in 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 fore bearing chamber 3, be connected by rear bearing 11 between the rear end of armature spindle and rear bearing chamber 10.Described forward flange 1 and rear flange 12 are all 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 rotation, 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 impeller 18 natural circulation heat radiations.
