Abstract
The utility model provides an oil-immersed type transformer with a cooling pipeline, which contains a transformer and an oil tank of the transformer, wherein the transformer is installed in the oil tank of the transformer, the inside of the oil tank of the transformer is also provided with a cooling pipeline except for cooling oil, the head end and the tail end of the cooling pipeline penetrate through the wall of the oil tank and extend out of the outside of the wall of the oil tank, the cooling pipeline is provided with an inlet and an outlet, and the inlet and the outlet of the cooling pipeline are connected with a coolant supply device. The condition that the rise of the temperature of the oil tank can not be too quick and too high can be ensured, the cooling effect of the oil tank is effectively enhanced, and the reliability and the safety of a system are enhanced.
Description
Technical field:
The utility model relates to a kind of oil-filled transformer, the oil-filled transformer that is particularly cooled off by water or other mediums.
Background technology:
Power transformer is in running; Because of reasons such as iron loss, eddy current can make the rising of transformer temperature too fast, too much; Particularly this situation of high-tension transformer is especially serious, special cooling system must be set just can make the transformer efficiently radiates heat, otherwise can influence its normal operation.
The vertical cooling radiator of single tube is adopted in the cooling of existing transformer usually; But across a cooling water pipe, so its radiating effect is not good between vertical cooling radiator of single tube and the oil tank wall, causes the oily temperature rise in the fuel tank too fast; Its poor reliability can not guarantee the long-time normal operation of transformer.Therefore, need a kind of good heat dissipation effect, reliable radiator to improve above-mentioned deficiency.
The utility model content:
The purpose of the utility model provides a kind of oil-filled transformer with cooling pipe, and ability quick heat radiating and ability long-time steady operation are avoided too fast, the too much deficiency of transformer oil temperature rise.
Realize a kind of oil-filled transformer of the utility model with cooling pipe; Its technical scheme is following: a kind of oil-filled transformer with cooling pipe; Comprise transformer and oil tank of transformer; Transformer is installed in the oil tank of transformer, it is characterized in that: said oil tank of transformer inside also is provided with cooling pipe except cold oil, the head end of said cooling pipe and end pass oil tank wall and stretch out in the oil tank wall outside; Said cooling pipe has import and outlet, and the import of said cooling pipe is connected with the refrigerant feeding mechanism with outlet.
For better technique effect, a kind of its technical characterictic of oil-filled transformer with cooling pipe of the utility model can also be specially following technical characterstic:
1. the top cover of said oil tank of transformer and bottom also can be provided with cooling pipe.
2. the cross section of said cooling pipe can be circle, triangle, square, hexagon or other polygonal shapes.
3. said cooling pipe distributes for wriggling.
Adopt the oil-immersed type transformer of the band cooling pipe of technique scheme to have following advantage:
1. said cooling pipe is in fuel tank internal and directly contacts with the cold oil of transformer, makes heat exchange faster, and radiating effect is better;
2. adopt the cooling of duct type refrigerant, and cooling pipe distributes for wriggling, utilize the pipeline that wriggles to accelerate to dispel the heat with the big characteristics of the contact-making surface of cold oil;
3. adopt duct type circulation cooling; The quick cooling of the flow velocity that can be through regulating the refrigerant feeding mechanism and the temperature realization transformer of refrigerant; It is too fast, too high to guarantee that the fuel tank temperature can not raise, and effectively improves the cooling effect of fuel tank, improves system reliability and fail safe;
4. each cooling pipe in the fuel tank can be connected with the refrigerant feeding mechanism individually or simultaneously, strengthens the heat exchange effect.
Description of drawings:
Fig. 1 and Fig. 2 are the inner stereogram of oil-filled transformer of band cooling pipe of the embodiment of the utility model
Fig. 3 is the stereogram of oil tank for oil immersion type transformer of band cooling pipe of the embodiment of the utility model
Among the figure, 1 is oil tank of transformer, and 101 is the oil tank of transformer sidewall, and 102 is accumulator, and 2 is cooling pipe, and 201 is the cooling pipe import, and 202 are the cooling pipe outlet, and 3 is transformer.
Embodiment:
Below in conjunction with accompanying drawing the embodiment of the utility model is done detailed description:
Shown in Fig. 1-3; The oil-filled transformer of the band cooling pipe of the utility model comprises transformer 3 and oil tank of transformer 1, and oil tank of transformer 1 inner space forms an accumulator 102; Transformer 3 is immersed in the cold oil in the accumulator 102; Cooling pipe 2 is in the accumulator of said oil tank of transformer, and its head end passes the lateral wall 101 of fuel tank with end and stretches out in beyond the lateral wall 101, and said cooling pipe 2 distributes for wriggling; Said oil tank wall 101 is tightly connected with the part that said cooling pipe 2 contacts, and said cooling pipe has import 201 and outlet 202.In the present embodiment, it is continuous with straight tube that the sinuous cooling pipe that distributes 2, two 2 of the row's cooling pipes of two rows are set in interior two the relative sidewalls of said oil tank of transformer.The head end of cooling pipe 2 passes the lateral wall 101 of fuel tank with end and stretches out in beyond the lateral wall 101, and said cooling pipe has import 201 and outlet 202.The import 201 of above-mentioned cooling pipe is connected with the refrigerant feeding mechanism with outlet 202, the quick cooling of the flow velocity that can be through adjusting refrigerant feeding mechanism and the temperature realization transformer of refrigerant, and it is too fast, too high to guarantee that the fuel tank temperature can not raise.Said refrigerant feeding mechanism can be circulation-supplied device or acyclic feeding mechanism.
For better cooling effect, in practical application, many row's cooling pipes can be set, also can in the top cover and the bottom of said oil tank of transformer cooling pipe be set arbitrarily.
The cross section of the described cooling pipe of present embodiment is circular with the simplified apparatus structure, makes its good heat dissipation effect, makes easily, reduces cost.The shape of cooling water pipe can also be designed to triangle or square or hexagon or other shapes according to actual needs in practical application.
Adopt the transformer of the utility model technical scheme can be widely used in technical fields such as electric power system, ozone generator, particularly need the occasion of high-tension transformer.
