<p>PURPOSE:To provide crossarm fitting metallic parts for high-voltage pole switches which make work easy and safe, and are suitable for manipulator operation in a robot fitting method. CONSTITUTION:The lower side 11b of a fastening fixing metallic part 11, formed approximately in the overall shape of U to insert a crossarm, and having a cross section approximately in the shape of U formed by cutting an opening in the inner periphery, is fixed approximately to the center of a fitting metallic part body 5 fixed to the upper part of a switch 1. A transverse side 12b and a longitudinal side 12a of an approximately L-shaped fastening movable metallic part 12 are put respectively in the lower side 11b of this fastening fixing metallic part 11 and a connecting side 11c linking the upper and lower sides. And a fastening bolt 13 inserted from the upper side 11a of the fastening fixing metallic part 11 is screwed to the upper part of the longitudinal side of this fastening movable metallic part 12, and the fastening movable metallic part 12 is made movable upwards and downwards by the rotation of the said fastening bolt 13. And the switch 1 is fitted by fastening the crossarm, with the upper side 11a of the fastening fixing metallic part 11 and the transverse side 12b of the fastening movable metallic part 12.</p> |
