Abstract

PURPOSE: To protect a transformer against the external and internal electric surge without raising cost by excessively wrapping the interval between the start and the end after several turns of the winding of the primary and secondary coils respectively of the trnasformer for welding.
CONSTITUTION: To wrap the insulator 17 consisting of insulating paper etc. around the iron core of a transformer for welding and to wind the insulating coil 2' of the primary winding around this part. Thereby the interval between the start P1 of winding and the part P2 after several winding turns of the coil 2' will be wrapped with an added insulator 19. Or the outside of this part between P1 and P2 will be provided either with the insulator 20 or after jointly using the insulators 19 and 20, the outside of the coil 2' will be surrounded by the insulator 18. The coil of the secondary winding will be equally treated and only the end part of the coil having the weakest insulating strength against surge will be reinforced with insulation.
