Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Referring to accompanying drawing 1-5, the scheme of a kind of water-cooled transformer and cooling device thereof, comprise: transformer body, cooling device forms, transformer body is mainly by iron core, primary coil, secondary coil forms, and its structural principle is consistent with widely used traditional transformer main body on market, for the water capacity of its cooling device larger, dismounting is simpler, it is characterized in that: described cooling device consists of two or more water cooled panels, the embedded encirclement of described water cooled panels is arranged between the primary coil and secondary coil in transformer body, primary coil in cooling device and main body and the heat exchange area of secondary coil have been increased, so heat in can extraordinary absorption transformer body, further described water cooled panels is provided with water collecting nozzle, this kind of cooling device of this kind do not form a complete circle coil, the potential difference that is two water collecting nozzles in its water cooled panels is 0 volt, the position that is to say two water collecting nozzles in its water cooled panels is not charged, without pure water, make recirculated water, recirculated water can be not charged yet, the fail safe of water cooling plant while having guaranteed transformer operation, greatly expanded its range of application.。
For reach with above-mentioned cooling device in installation effect, heat radiation and the effect of water cooled panels, its water cooled panels can have following several preferential scheme:
