Abstract

The invention discloses a low-noise oil-immersed power transformer, which includes a box body, an oil tank, a box cover and a base. Two guard plates are arranged on both sides of the box cover, and a high-voltage terminal and a low-voltage terminal are provided on the top of the box cover. , There is an oil tank in the box, stirring fan blades are respectively installed on both sides of the inner wall of the oil tank through a driving device, a liquid level gauge is installed on one side of the outer wall of the box, and a base is installed at the bottom of the box. The present invention changes the circulation path in the transformer oil tank by arranging stirring fan blades inside the oil tank, increases the oil circulation strength and speed inside the oil tank, thereby improving its heat dissipation performance, and sets aluminum foil outside the high-voltage coil and the low-voltage coil The shielding layer has a good shielding effect, and the thickness of the aluminum foil shielding layer is small. The limit block is just inserted into the channel steel, so that the two ends of the limit block can withstand the bolts, so that the connection of the bolts does not loosen, ensuring the connection of the entire structure. stability, thereby reducing the generation of extra noise.

Description

technical field [0001] The invention relates to a transformer, in particular to a low-noise oil-immersed power transformer. Background technique [0002] The existing oil-immersed transformer will continuously increase the oil temperature during the working process. The oil temperature generally reduces the oil temperature through the circulation between the tank wall and the inside of the oil tank, but the oil circulation process between the inner wall and the inside of the oil tank is slow, and the convection of the oil The low strength and high local oil temperature are not conducive to reducing the oil temperature of the oil-immersed transformer. Vibration will cause noise pollution and affect the work and rest of people around. The thickness of the insulating layer is large. When winding the coil, the center wire consumables are increased and the production cost is increased. Therefore, we have improved this and proposed a low-noise oil-immersed power transformer. SU...
