Abstract
The invention aims to provide an oil-cooled transformer to improve the cooling effect of the transformer. The oil-cooled transformer comprises a transformer body consisting of a first winding, a second winding and iron cores for winding the first winding and the second winding. The transformer body is fixed in a transformer shell, and transformer oil is filled in the transformer shell. The oil-cooled transformer is characterized in that the transformer shell is communicated with an auxiliary heat dissipation cavity through an oil inlet pipe and an oil outlet pipe, and an oil pump is arranged in the auxiliary heat dissipation cavity to drive the transformer oil to flow circularly between the transformer shell and the auxiliary heat dissipation cavity. The transformer is provided with the auxiliary heat dissipation cavity to realize the flowing and cooling of the transformer oil, so that the cooling effect of the transformer is improved, and the practicability is good.
Description
Technical field
The invention belongs to technical field of electricity, specially refer to a kind of transformer.
Background technology
Transformer can produce a large amount of heat when work, must in time dissipate, otherwise can cause that the temperature in the transformer rises, and affects its normal operation.In traditional high-power transformer housing transformer oil is housed all, utilizes transformer oil that winding and the iron core of transformer are cooled off, but because transformer oil is not mobile, so radiating effect is limited.
Summary of the invention
The objective of the invention is to propose a kind of oil-cooled transformer, to improve the cooling effect of transformer.
Oil-cooled transformer of the present invention comprises the transformer body that the iron core by the first winding, the second winding and reel described the first winding and described the second winding forms, described transformer body is fixed in the transformer shell, in the described transformer shell transformer oil is housed, key is that described transformer shell is communicated with an auxiliary heat dissipation cavity by oil inlet pipe and flowline, be provided with oil pump in the described auxiliary heat dissipation cavity, circulate between transformer shell and auxiliary heat dissipation cavity with driving transformer oil.
When transformer is worked, the heat that the winding of transformer and iron core produce can be transmitted to transformer oil, and oil pump driving transformer oil circulates between transformer shell and auxiliary heat dissipation cavity, transformer oil is cooled off at the auxiliary heat dissipation cavity, the temperature that flow back into the transformer oil in the transformer shell is reduced, thereby better winding and the iron core of transformer cooled off.
Further, for improving radiating rate, the surface of described auxiliary heat dissipation cavity is provided with fin, with the increasing area of dissipation, thereby improves radiating effect.
Transformer of the present invention has been realized flowing and cooling of transformer oil by the auxiliary heat dissipation cavity is set, thereby can improve the cooling effect of transformer, has good practicality.
Description of drawings
Fig. 1 is the structural representation of oil-cooled transformer of the present invention.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the oil-cooled transformer of the present embodiment comprises the transformer body 1 that the iron core by the first winding, the second winding and reel described the first winding and described the second winding forms, described transformer body 1 is fixed in the transformer shell 2, in the described transformer shell 2 transformer oil is housed, key is that described transformer shell 2 is communicated with an auxiliary heat dissipation cavity 5 by oil inlet pipe 3 and fuel-displaced 4 pipes, be provided with oil pump 6 in the described auxiliary heat dissipation cavity 5, circulate between transformer shell 2 and auxiliary heat dissipation cavity 5 with driving transformer oil.
When transformer is worked, the heat that the winding of transformer and iron core produce can be transmitted to transformer oil, and oil pump 6 driving transformer oil circulate between transformer shell 2 and auxiliary heat dissipation cavity 5, transformer oil is cooled off at auxiliary heat dissipation cavity 5, the temperature that flow back into the transformer oil in the transformer shell 2 is reduced, thereby better winding and the iron core of transformer cooled off.
Further, for improving radiating rate, the surface of described auxiliary heat dissipation cavity 5 is provided with fin 7, with the increasing area of dissipation, thereby improves radiating effect.
