Abstract
The utility model relates to a corrugation oil storage cabinet special for a transformer. The corrugation oil storage cabinet special for the transformer comprises a cabinet body, an oil storage core body and a pressure-regulating oil box. The cabinet body is in an octangle structure. The middle portion of the cabinet body is in a cuboid shape. The two ends of the cabinet body are in trapezoid shapes which are symmetrical with each other. A ridge-type top cap is arranged on the upper surface of the cabinet body. The side face of the oil storage core body is in a corrugation structure. The wave height of the corrugation is larger than the pitch of waves of the corrugation. An oil level view window is arranged on one side of the cabinet body in a protruded mode. The protruded height of the upper border-frame of the oil level view window is larger than the protruded height of the lower border-frame of that. A main connection pipe is arranged below the cabinet body. A corrugation pipe elbow is arranged at the lower end of the main connection pipe. An oil filler pipe is arranged on one side of the main connection pipe. Compared with the prior art, the stainless steel corrugation inner container of the corrugation oil storage cabinet special for the transformer is formed and machined by adopting one-time-forming process. Due to the smaller pitch of waves and larger wave height, the compensation ability is strong. The corrugation oil storage cabinet special for the transformer has the advantages of being novel in structure, fully sealed, free from maintenance and stable in running. The display of the rising of falling of the oil level is visualized, movement is flexible and degree of automation is high. Due to the fact that the corrugation inner container is installed vertically, the oil of a transformer is convenient to flow back thoroughly.
