Abstract

The utility model provides a transformer which is good in cooling effect. The transformer comprises a first winding, a second winding and a transformer body which is composed of iron cores which are used for winding the first winding and the second winding, wherein the transformer body is fixed in a transformer shell body, and the transformer body is filled with transformer oil. The transformer is characterized in that the transformer body is provided with an oil pump, and the outer surface of the transformer shell body is provided with a cooling fin. When the transformer works, the heat produced by two windings and the iron cores will be conducted to the transformer oil, the oil pump drives the transformer oil to flow in the transformer shell body, thereby enabling the temperature of the transformer oil in the transformer shell body to be more even, reducing the heat concentration in the transformer body, and reducing the temperature of the transformer oil, thus preferably cooling the two windings and the iron cores of the transformer. The cooling fin can increase the heat dissipating area, thereby improving the heat dissipation effect.

Description

A kind of transformer

Technical field

The utility model belongs to technical field of electricity, specially refers 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.

The utility model content

The purpose of this utility model is the transformer that proposes a kind of good cooling results.

Transformer of the present utility model 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, it is characterized in that in the described transformer shell oil pump being housed, the outer surface of described transformer shell is provided with fin.

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 flows in transformer shell, make the temperature of the transformer oil in the housing more even, thereby the heat that reduces the transformer body place is concentrated, and the temperature of transformer oil is reduced, thereby better winding and the iron core of transformer cooled off; Fin can strengthen area of dissipation simultaneously, thereby improves radiating effect.

Further, for improving radiating rate, described transformer body is arranged in the transformer shell by bracket-suspending, described oil pump is arranged at the below of transformer body, and the oil-out of oil pump is towards transformer body, can improve like this flow velocity of the transformer oil at transformer body place, take away quickly the heat of transformer body.

Transformer of the present utility model has been realized flowing and cooling of transformer oil by oil pump is set, thereby can improve the cooling effect of transformer, has good practicality.

Description of drawings

Fig. 1 is the structural representation of transformer of the present utility model.

Embodiment

The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of embodiment of the present utility model 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 transformer of 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, oil pump 3 is housed in the described transformer shell, and the outer surface of described transformer shell 2 is provided with fin 4.

When transformer is worked, the heat that the winding of transformer and iron core produce can be transmitted to transformer oil, and oil pump 3 driving transformer oil are transformer shell 2 interior flowing, make the temperature of the transformer oil in the housing 2 more even, thereby the heat that reduces transformer body 1 place is concentrated, and the temperature of transformer oil is reduced, thereby better winding and the iron core of transformer cooled off; Fin 4 can strengthen area of dissipation simultaneously, thereby improves radiating effect.

Further, for improving radiating rate, described transformer body 1 is by support 5 unsettled being arranged in the transformer shell 2, described oil pump 3 is arranged at the below of transformer body 2, and the oil-out of oil pump 3 is towards transformer body 1, can improve like this flow velocity of the transformer oil at transformer body 1 place, take away quickly the heat of transformer body 1.
