YB-12 Pre-assembled box substation(American substation)

YB-12 prefabricated box type substation (commonly known as American box transformer) has a "V" - shaped structure, and the transformer is closely connected to the high and low voltage equipment. The transformer is exposed to the air on three sides, with good heat dissipation conditions, and can be separated from the high and low voltage equipment shell for easy maintenance. The transformer adopts a 813 series oil immersed transformer with a plate type oil tank, no oil pillow, and fully enclosed. The high and low voltage bushings, tap changer oil level indicators, pressure relief valves, oil relief valves, etc. are all installed on the end plate of the high voltage compartment body, with reasonable positions, easy observation, and operation. The high-voltage and low-voltage compartments are separated by steel plates, and the transformers in the high-voltage and low-voltage compartments are relatively independent while maintaining a complete box transformer as a whole. The structure is c…
