Title: Sheet wound transformer
Inventor: HANAI MASAHIRO
IPC: H01F27/28
Filed: 1988-07-07
Abstract: PURPOSE:To reduce insulating influence of foreign matter even if the matter is mixed by interposing an insulator sheet between two metal sheets and winding them. CONSTITUTION:When sheets are wound by a winding machine, upper and lower metal sheets are so employed as to interpose an insulator sheet 2 therebetween to compose a winding, and a cooling panel 3 is inserted between the metal sheets 1. Accordingly, since the cooling panel is inserted between the metal sheets of the same potential, it does not affect the influence to an electrostatic capacity between turns. Even if a foreign matter drops to ride on the sheet 1 due to a certain malfunction when the sheet winding is wound, it is interposed between the metal sheets. Thus, the matter does not affect the adverse influence to the sheet 2 thereby to obtain a sheet wound transformer having reliability.
