10 KV oil-immersed Transformers three-phase

10 KV oil-immersed Transformers three-phase Performance characteristics a, oil immersed transformer low-voltage winding in addition to the small capacity of copper wire, generally use copper foil winding cylinder structure; The high voltage winding adopts the multi-layer cylinder structure, so that the ampere-turns distribution of the winding is balanced, the magnetic leakage is small, the mechanical strength is high, and the short-circuit resistance is strong. b, the iron core and the winding are respectively using fastening measures, the device height, low pressure lead and other fastening parts are equipped with self-locking locknut, the use of non-hanging core structure, can withstand the transport of the shock. c, coil and core using vacuum drying, transformer oil using vacuum filter oil and oil injection process, so that the moisture inside the transformer to a minimum. D. The oil tank adopts corrugated sheet, which has respiratory function to compensate for the volume chan…
