Title: Oil-filled transformer
Inventor: NAKATANI JIRO
IPC: H01F27/02
Filed: 1985-02-27
Abstract: PURPOSE:To contrive the enlargement of an effective space by simplifying the piping system of the top surface of a transformer tank, by a method wherein the maximum oil surfaces of a high-tension pushing pocket and a low-tension pushing pocket located at the top surface of the transformer tank are made different in level; a hollow stay connecting between these oil surfaces are joined to both pockets, and a degassing pipe is joined to the upper end of the high- tension pushing pocket. CONSTITUTION:Insulating oil heated in a transformer tank 1 rises to a high- tension pushing pocket 20 and a low-tension pushing pocket 21. The insulating oil which has risen to the latter pocket 21 flows into the former one 20 via hollow stay 22a and flows from the upper oil pipe 8 to a cooler 7 directly or via stay 22b together with the insulating oil which has risen to the pushing pocket 20. This flown insulating oil passes into transformer tank 1 via lower oil piping 10 by means of oil-feeding pump 9 after being cooled likewise as conventional. On the other hand, the degassing of the pushing pockets 20 and 21 is performed via degassing pump 23 of the pushing pocket 20.
