The heat dissipation fins 10 are vertically installed on the side wall of the oil tank 2 and protrude from the plane of the oil tank 2, which can increase the surface area of the oil tank 2 and improve the heat dissipation effect, thereby reducing the working temperature of the transformer.
[0031] Preferably, the circulating pump 8 and the flowmeter 7 are electrically connected; the temperature detector 6 is a digital thermometer, and the digital thermometer is electrically connected with the circulating pump 8 and the flowmeter 7.
