Abstract
PURPOSE: To simplify the insulation structure between windings without reducing the insulation strength by composing an inter-winding insulation device for oil- filled transformer employing a flanged insulating spacer.
CONSTITUTION: Flanged insulating spacers 6 and 7 having at least one each of flanges 6A and 7A extending in the circumferential direction is arranged between insulated cylinders adjacent to respective windings 2 and 3, and the flanges adjacent to each other are overlapped in the radial direction of the winding through a small clearance serving as oil gap therebetween. With such an arrangement, as the oil gap between the insulated cylinders 4 is subdivided with the flanges 6A and 7A, the breakdown voltage of the oil gap can be elevated with a simple construction eliminating intermediate insulated cylinder.
