Abstract
The utility model discloses the strong oily circulation gilled radiator of a kind of oil-filled transformer, on its original basis, set up axial-flow pump, axial-flow pump is made up of motor, shaft coupling (5), axle (6) and impeller (7); Described motor is arranged on the relative one end of oil-out flange (11), and motor is docked with axle (6) by shaft coupling (5), and impeller (7) is assemblied on the axle (6) of oil-out flange (11); Axial-flow pump motor belt motor moving axis, axle interlock impeller forces transformer oil flow velocity to accelerate, thus improves radiating efficiency, delays winding insulation material aging speed, improves the useful life of transformer.
Description
Technical field
The utility model relates to a kind of transformer, and specifically the strong oily circulation gilled radiator of a kind of oil-filled transformer, belongs to transformer technical field of heat dissipation.
Background technology
Oil-filled transformer is immersed in inside special transformer oil by the device body of transformer, and transformer oil not only as dielectric but also can carry out heat transfer as heat-conducting medium.Because device body is immersed in oil, therefore to the heat conduction of device body with distribute higher requirement: when oil-filled transformer runs, inner winding, the parts that wait unshakable in one's determination produce loss, and loss is converted to heat and passes to oil tank wall by the heat transfer of transformer oil and convection action, make winding, iron core, oil tank wall and oil surface temperature rise, and temperature rises and directly has influence on the life-span of winding insulation material, therefore must temperature rise be controlled in certain scope, it be necessary for therefore adopting radiator to carry out dispelling the heat.
Current normally used radiator, transformer oil mainly leans on thermal convection heat conduction in its inside transformer, as shown in Figure 1: namely hydraulic oil enter from top oil-in, bottom oil-out flow out, in its process, transformer oil flowing slowly, radiating effect is poor, cause the service life reduction of winding insulation material, cause transformer to reduce useful life further, be difficult to satisfied current cooling requirements.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of oil-filled transformer strong oily circulation gilled radiator, radiating efficiency can be improved, meet the requirement of oil-filled transformer to heat radiation, ensure the life-span of winding insulation material, improve the useful life of transformer further.
To achieve these goals, the technical solution adopted in the utility model is: the strong oily circulation gilled radiator of a kind of oil-filled transformer, comprise and be arranged on oil-in flange on oil-filled transformer oil circuit piping and oil-out flange, also comprise axial-flow pump, axial-flow pump is made up of motor, shaft coupling, axle and impeller; Described motor is arranged on the relative one end of oil-out flange, and motor is docked with axle by shaft coupling, and impeller is assemblied on the axle of oil-out flange.
Further, motor comprises motor stator, rotor and motor winding.
Preferably, impeller is three, quantity is multiple.
Preferably, axle is near the end mounting limit mechanism of oil-out flange.
Further, oil-out place set temperature transducer.
Compared with existing cooling system, the utility model, on original basis, has set up axial-flow pump, axial-flow pump motor belt motor moving axis, axle interlock impeller forces transformer oil flow velocity to accelerate, thus improves radiating efficiency, delay winding insulation material aging speed, improve the useful life of transformer; Further, because transformer temperature rise is low, can suitably reduce winding conducting wire cross section, copper consumption reduces, and window unshakable in one's determination reduces, and then silicon steel sheet consumption reduces, and fuel tank reduces, and overall volume reduces, and reduces thus greatly reduce manufacturing cost, energy savings by oil mass.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, the strong oily circulation gilled radiator of the utility model oil-filled transformer, comprise and be arranged on oil-in flange 1 on oil-filled transformer oil circuit piping and oil-out flange 11, also comprise axial-flow pump, axial-flow pump is made up of motor, shaft coupling 5, axle 6 and impeller 7; Described motor is arranged on the relative one end of oil-out flange 11, and motor is docked with axle 6 by shaft coupling 5, and impeller 7 is assemblied on the axle 6 of oil-out flange 11.
Further, motor comprises motor stator 2, rotor 3 and motor winding 4, and moving axis 6 is with by rotor 3.
Preferably, impeller 7 is more than three or three, quantity is more than one, and multiple quantity and mutliblade impeller 7, can further improve oily circulation velocity to a certain extent, improve radiating efficiency further.
Preferably, axle 6, near the end mounting limit mechanism of oil-out flange 11, prevents impeller 7 from departing from axle 6.
Further, at oil-out place set temperature transducer, the temperature of transformer oil can be monitored in real time, to control unlatching and the stopping of axial-flow pump, ensure radiating effect.
During work, after electrical power, electronics rotor 3 rotates, impeller 7 on universal driving shaft 6, axle 6 rotates simultaneously, forces transformer oil high-speed circulating to flow, makes oily fast flow faster, thus reach thus reach the object reducing transformer temperature rise fast; Along with transformer temperature rise reduces, delay Transformer Insulation Aging speed, greatly improve transformer useful life, further, because transformer temperature rise is low, can suitably reduce winding conducting wire cross section, copper consumption reduces, window unshakable in one's determination reduces, and then silicon steel sheet consumption reduces, and fuel tank reduces, overall volume reduces, reduce by oil mass thus greatly reduce manufacturing cost, energy savings, there are wide market prospects.
