Title:
CURRENT TRANSFORMER HOLDING TOOL OF SWITCH
Document Type and Number:
Japanese Patent JP3069272
Kind Code:
B2
Abstract:
PURPOSE: To simplify the operation of mounting a current transformer and adjusting its position by giving flexibility to at least a small-diameter flange part and a cylindrical part on the small-diameter flange side so that it can pass through a bushing mounting hole and the inside of a current transformer.
CONSTITUTION: In a current transformer holding tool, a cylindrical part 12 a large and a small flanges 13, 14 at its both ends are integrally formed. For their material, a deformable rubber material or the like is used. When installed, a current transformer is pushed into the cylindrical part 12 side from the small- diameter flange 14 side while the flange 14 and the cylindrical part 12 are inwardly made narrower. Further, a bushing is inserted into the cylindrical part 12 fitted in a bushing mounting hole from the outside of the external box of a switch. When the bushing is inserted up to a predetermined position, the flange of the bushing is made to abut on the flange 14. Next, a pushing plate is pushed against the outside of the flange.
