Abstract

The utility model discloses a cooling device for a pancake coil of an oil-immersed transformer. A transverse baffle plate is additionally installed in horizontal oil ducts of the original cooling device, and the original horizontal oil ducts which are mutually independent are connected into a whole to form an S-shaped cooling oil duct, so that the problem that cooling transformer oil in the horizontal oil ducts in the original cooling system is not circulated or is circulated slowly is solved, and the insulating property of the transformer oil and the service life of the transformer are improved.

Description

The cooling device of oil-filled transformer disc coil
Technical field
The utility model relates to a kind of transformer, particularly relates to a kind of cooling device of oil-filled transformer disc coil.
Background technology
The cooling of oil-filled transformer disc coil mainly is to rely on the heat conductivility of transformer oil to realize, the oil duct that is clipped in the oil-filled transformer disc coil cooling system in the market between coil is the level trend, and be independently each other, the shortcoming of this structure is to cause the transformer oil in the horizontal oil duct to have the too slow of circulation or circulation hardly, be unfavorable for the cooling of disc coil, cause coil temperature too high, thereby influence the insulation property of transformer oil and the useful life of transformer.
The utility model content
For solving the above-mentioned technical problem that prior art exists, the purpose of this utility model is to provide a kind of cooling device of oil-filled transformer disc coil, eliminated between the oil-filled transformer disc coil because transformer oil does not circulate or to be circulated throughout the coil temperature that is caused slowly too high, and then influenced the problem in the useful life of the insulation property of transformer oil and transformer.
For achieving the above object, the utility model provides a kind of cooling device that is used for the oil-filled transformer disc coil, has the horizontal oil duct that forms between two coil windings, it is characterized in that: in the middle of the described horizontal oil duct some dividing plates are set, original separate horizontal oil duct is linked into an integrated entity, and S-shaped.
Cooling device described in the utility model, simple in structure, easy to operate, have additional the dividing plate of horizontally set between coil windings, transformer oil can flow by guiding, has improved the circulation rate of transformer oil between the disc coil, avoided oily stream dead band, effectively improve the radiating efficiency of disc coil, suppressed the temperature rise of coil, improve the useful life of dielectric strength and transformer.
The utility model content
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
Fig. 1 is the schematic diagram of existing oil-filled transformer disc coil winding cooling device structure.
Fig. 2 is a structural representation of the present utility model.
Embodiment
Prior art oil-filled transformer disc coil winding cooling device as shown in Figure 1, the horizontal oil duct 4 that forms between oil duct 3 that is formed for cooling off between its coil windings 1 and the transformer body 2 and two coil windings, transformer oil flows by oil duct and forms oil stream, but this oil stream concentrates on the coil outside mostly, be difficult in and form oil stream in the horizontal oil duct 4, the heat that winding produces fully can't be shed, and be easy to generate the dead band of oil stream, cause coil to spread the low temperature rise of the heat efficiency and improve.The utility model oil-filled transformer disc coil cooling device as shown in Figure 2, between disc coil 1, increase the dividing plate 5 of a plurality of horizontally sets, the horizontal oil duct 4 that disc coil is clipped between the disc coil is cut apart again, make it connect into an integral body and S-shaped, thereby the guiding transformer oil flows into by the horizontal oil duct 4 between the coil windings 1, form directed oil stream 3, thereby make the transformer oil in the horizontal oil duct 4 between the coil windings 1 fully to circulate, to take away the heat that coil windings 1 is produced, eliminated the dead band of oily stream, effectively reduce the temperature rise of coil windings 1, the useful life of improving dielectric strength and transformer.
