Abstract

PURPOSE:To reduce the diameter of a current transformer containment container and to improve the workability of clamping bolts by fixing a plurality of mounting seats on the inner surface of the container and inserting and rotating retainers each having cutout at the position corresponding to the seat into the container. CONSTITUTION:A plurality of retainer mounting seats 9 each having a mounting hole in parallel with the axis of the container 1 are fixed approximately on the same circumference inside the container 1. The retainer 10 includes a cutout having an outer diameter smaller than the inner diameter of the seat 9 to make it possible to release the seat 9 when inserting into the container 1. When the retainer 10 is inserted into the container 1 and is then rotated, the projection allows to coincide therewith behind the seat 9. In this state, the retainer 10 can be fixed to the seat 9 by the bolt 11.
