Abstract
The invention discloses an oil-immersed transformer. A voltage transformation component installation rack is arranged in the oil-immersed transformer, a hot oil suction nozzle is arranged at the upper end of the interior of the oil-immersed transformer, the left side wall and the right side wall of the oil-immersed transformer are provided with hot oil cooling bins, suction power devices are arranged at the upper ends of the hot oil cooling bins, a plurality of cooling devices are arranged in each of the hot oil cooling bins, a cold oil storage groove is arranged at the bottom of the oil-immersed transformer and communicated with the bottoms of the hot oil cooling bins, and a pressurized guide device is arranged in the cold oil storage groove. The transformer disclosed by the invention is simple in structure and novel in design; a combined mode of active cooling and natural cooling is adopted; and in active cooling, hot oil of the upper layer of the transformer is pumped out and returns to the transformer from the bottom after the temperature is reduced by the cooling devices at the outer sides, and thus, the cooling efficiency of the transformer is greatly improved.
Description
technical field:
The present invention relates to transformer technology field, be specifically related to a kind of oil-filled transformer.
background technology:
Oil-filled transformer has the features such as loss is low, capacity is large, price is low.The power transformer major part of current electric online operation is oil-filled transformer.Oil-filled transformer is in running, and the power consumption in iron core and winding changes heat into, ensure the normal operating temperature of transformer for useful life of transformer and stable operation significant.Present routine adopts fin to increase the heat dissipation channel of oil tank wall, and conventional mode is the surrounding being distributed in transformer oil tank wall.Increase heat dissipation channel, only have the volume increasing fuel tank.Such improved procedure increases the cost of manufacture of floor space and fuel tank.
summary of the invention:
For above-mentioned deficiency, the invention provides a kind of oil-filled transformer.
The present invention is by the following technical solutions:
A kind of oil-filled transformer, comprise oil-filled transformer, transformation element installation bracket, deep fat suction nozzle, suction power plant, deep fat cooling storehouse, cooling device, cold oil storage tank, pressurized pilot device, insulation plate, the inside of described oil-filled transformer is provided with transformation element installation bracket, and the inner upper end of oil-filled transformer is provided with deep fat suction nozzle; The left and right sidewall of described oil-filled transformer is provided with deep fat cooling storehouse, and the upper end in deep fat cooling storehouse is provided with suction power plant, and suction power plant is connected with the deep fat suction nozzle of oil-filled transformer inside; The inside in described deep fat cooling storehouse is provided with several cooling device; The bottom of described oil-filled transformer is provided with cold oil storage tank, and cold oil storage tank and deep fat cool bottom storehouse and be communicated with, and the inside of cold oil storage tank is provided with pressurized pilot device, is provided with insulation plate between described oil-filled transformer and cold oil storage tank.
The rear and front end of described oil-filled transformer is provided with natural heat dissipation comb.
Described deep fat cooling storehouse is hermetically-sealed construction, and is integral type structure with oil-filled transformer.
Beneficial effect of the present invention: its structure is simple, novel in design, the mode combined both adopting active cooling and naturally cooling, wherein active cooling is extracted out by the deep fat on transformer upper strata, after cooling device cooling by outside, that refluxes from bottom enters transformer again, substantially increases the radiating efficiency improving transformer.
