Component parts include: transformer winding (Dyn11, Yyn0) the body, the cabinet housing

Combined Transformer is the body of the transformer, switchgear, fuses, tap combination and the corresponding auxiliary equipment transformers, also known as box-type transformer in the country also known as American box. Its constituent parts, including:  electri cenergy meter  winding (Dyn11, Yyn0) the body, box casing, inlet and outlet tube wells, connecting leads, load switch, back-up fuse, insert the fuse,  mcb circuit breaker  indicating instrument, tap, low outlet terminals, low-voltage circuit breakers, compensation capacitors, high voltage cable accessories. As most of the lead parts are installed in the transformer tank, and its connection to the tank after running process determines whether there is the possibility of oil leakage, although manufacturers in the box transformer factory have adopted strict process measures, but due to put into operation site conditions vary, connecting parts of the oil leakage situation occur, the author personally come into contact with several oil leakage and treatment methods to do a detailed introduction.
