な距離をとることができる。This insulation support (71K) requires reliable insulation between earth and phases, and also requires insertion force when inserting the circuit breaker (5), vibration during opening/closing operation of the circuit breaker, and strong electromagnetic force when short-circuit current is applied. It requires sufficient strength to withstand force.For this reason, the shape of the insulating support (7) was designed as shown in Figures 3 to 9J4.Basically, the beam (7C) of the insulating support (7) ) was made into an H shape as shown in the cross-sectional view of Figure 4!J4 to ensure mechanical strength, and the recess in the center of the H shape works effectively for the insulation creepage distance between the ground and the ground. The main circuit terminals were arranged in a position where the insulation distance could be long. Therefore, as shown in Figure 4, the insulation creepage distance is determined by the insulation creepage distance from fire to ground: EL or from the insulation creepage distance to phase: PL, respectively. You can keep a sufficient distance from
