Magnetic flux leakage driving type heat dissipation oil tank of transformer

Abstract

The invention discloses a magnetic flux leakage driving type heat dissipation oil tank of a transformer. The magnetic flux leakage driving type heat dissipation oil tank comprises a tank body, whereintwo porous shields are symmetrically mounted on the outer side wall of the tank body; an oil pumping pipe and an oil discharging pipe are respectively stacked and coiled on the upper wall and the lower wall of the inner side of each porous protective cover; two electromagnetic oil pumps are symmetrically installed on the outer side wall of the tank body; one ends of the oil pumping pipes and oneends of the oil discharging pipes are both installed on the electromagnetic oil pumps; the sections, away from the electromagnetic oil pumps, of the oil discharging pipes and the oil pumping pipes areinstalled above the side wall of the tank body and below the side wall of the tank body respectively; and magnetic leakage induction coils are symmetrically installed on the inner wall of the tank body. The magnetic leakage induction coils convert magnetic leakage of the transformer into electric energy to enable a driving shaft to rotate, the driving shaft rotates to drive an airflow fan and animpeller fan to rotate so as to increase an airflow contact heat exchange speed and a transformer oil circulation heat dissipation speed, so active heat dissipation is achieved, electric energy is saved, and the size of the transformer is not increased.

Description

technical field [0001] The invention relates to the field of power transformers, in particular to a transformer flux leakage driven cooling oil tank. Background technique [0002] The transformer will generate a lot of heat during use. Rapid heat dissipation of the transformer can increase the working efficiency of the transformer. The transformer cooling oil tank can make the transformer core winding immersed in the transformer oil, which not only provides good insulation protection, but also protects the core. Winding for heat dissipation. [0003] Existing transformer oil tanks usually use passive heat dissipation, that is, heat sinks or heat pipes are used for heat dissipation, and the heat dissipation speed is slow. Active heat dissipation requires the addition of active heat dissipation power modules, which not only increases the volume of the transformer, but also consumes a lot of power.
