PROBLEM TO BE SOLVED: To provide a compact stationary induction apparatus in which an on-load tap changer is efficiently disposed to reduce its footprint, and the size is reduced in a connection with a gas insulating open/close device and is small enough to be within the rail transport allowance. SOLUTION: A total of 3 units of single-phase on-load tap changers 42 are disposed with each in the vicinity of gas ducts 8 for extracting secondary lead wires 7. Insulating spacers 9 for separating an insulating oil filled in a tank 5 from an insulating gas filled on the side of the gas duct 8 are attached on the side of the longitudinal side of the tank 5, and near the each wingding wire 1, 2 and 3. Lead wires 6 and 7 are detachably connected to the gas duct 8 via the insulating spacer 9. COPYRIGHT: (C)2007,JPO&INPIT
