PROBLEM TO BE SOLVED: To provide an insulation support structure for a breaker, which can reduce the cost, using principal part in common for various current capacity of breakers. SOLUTION: An insulation support structure for a breaker is constituted of a breaker support frame 1 which has a rear plate, right and left plates 3 and 3', right and left partitions 4, and 4', and three-phase breaker supports 5u-5w, and an insulation barrier 11 which has a screen 12 and a pair of walls 13 and 13 and is attached to the top of the breaker support frame 1. Three- phase breakers are stored each in the breaker storage spaces Bu-Bw which are made by partitioning the space between the side plates 3 and 3' by partitions 4 and 4'. An insulation distance between phases at the time of the dimensions of a terminal conductor connected to the breaker being increased is secured by attaching the insulation barrier 11. |
