Oil-immersed power transformer

Abstract

The invention provides an oil-immersed power transformer. The oil-immersed power transformer comprises a safety air channel, a transformer box, an insulating sleeve, a transformer body, a heat-exchanging tube, an upper condenser, a lower condenser, thermal conductive discs, and a heat-exchanging fan; the thermal conductive discs for performing heat conduction are arranged on the upper surface and the lower surface of the transformer body; the upper condenser is arranged above the transformer box; the lower condenser, an air inlet and the heat-exchanging are arranged below the transformer box; the upper condenser and the lower condenser are connected with the thermal conductive discs through the heat-exchanging tube; and at least an air outlet is formed in the side wall of the transformer box. The heat-exchanging tube can rapidly cool the heat absorbed by the thermal conductive discs through the upper condenser and the lower condenser; meanwhile, the air inlet below the transformer box, the heat-exchanging fan and the air outlet in the side wall can rapidly perform air cooling on the transformer so as to greatly reduce the temperature of the transformer, so that the service life and the safety performance of the transformer can be improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular, the invention relates to an oil-immersed power transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core. In electrical equipment and wireless circuits, it is often used for raising and lowering voltage, matching impedance, safety isolation, etc. In a generator, whether the coil moves through the magnetic field or the magnetic field moves through the fixed coil, an electric potential can be induced in the coil. In both cases, the value of the magnetic flux remains the same, but the amount of magnetic flux intersecting the coil is different. Change, this is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current and impedance. The functions of the tr...
