Document Type and Number:
Japanese Patent JP3018946
Kind Code:
B2
Abstract:
PURPOSE: To make it possible to change safely a tap by a method wherein an insulating barrier is provided directly under an electrical wire for connecting the power supply sides of a high-voltage bushing and a high-voltage cutout with each other and a hand hole is provided in the external side surface, which is positioned at the intermediate part between the barrier and a no-voltage tap-changing plate, of a tank.
CONSTITUTION: A winding 8 mounted with a no-voltage tap-changing plate 14 is provided in a tank 9, a high-voltage bushing 1 and a high-voltage cutout 4 are respectively mounted in the upper side walls of the tank 9 and the power- supply sides of the bushing 1 and the cutout 4 are connected with each other through an electrical wire 3. The load side of the cutout 4 is connected with the winding 8 via the plate 14 through the wire 3. Moreover, a tabular insulating barrier 11 is provided directly under the bushing 1 and the cutout 4 in the tank 9 and a hand hole 14 is provided in the external side surface, which is positioned at the intermediate part between the barrier 11 and the plate 14, of the tank 9.
