Abstract
PURPOSE: To abbreviate the champing work, of a transformer core with many C- shape clamps and improve the operationability by a method wherein the upper and lower tank which onstitute a transformer tank are welded at each flange surface and this flange section is clamped.
CONSTITUTION: After the assembling of a core 5 is finished, an upper tank 1 is put over a lower tank 2 and the surface of connecting flanges 1a, 2a are welded at the welding section 7. At this time, the tightening force delivered from a core holder 3 to the core 5 is kept as only the weight of the tank 1 itself, and get rid of the neccessity of clamping with the C shape clamps. Then operating a vacuum pump 14, the inside of the tank is made to form a vacuum and make the atmospheric pressure to act in the direction shown with the arrow marks to the inside of tank. Availing the spring action of a gasket 6 inserted in the welding section 7, the tank 1 and 2 are tightened, and the core 5 is tightened strongly through the core holder 3 and a core holding board 4. Maintaining this condition, a reinforcement 9 for the tank 1 and a reinforcement 10 for the tank 2 are welded to a connection board 11 at the welding sections 15.
