<p>PURPOSE: To set a stably mounting state and to reduce in size and weight. CONSTITUTION: Protruding ridges 2 extending axially (vertically) are integrally formed at a plurality of, for example, four positions of the outer periphery of a through type current transformer 1 at the time of resin molding the transformer 1. A U-shaped groove 3 extending in an axial direction are formed at the center of each ridge 2, and a terrace-state flat part 4 is formed at the upper end. The part 4 corresponds to a spot facing, and the groove 3 is to set a clamping bolt 11. The transformer 1 is placed on a mounting frame while visually confirming the alignment of the groove 3 with the mounting hole of the frame. Thereafter, the bolt 1 is set to the groove 3, a washer, a nut 14 are mounted at the upper end, and the nut 14 is clamped. When the operations are conducted at four positions, the mounting is completed in a rigid mounting state.</p> |
