Abstract

PROBLEM TO BE SOLVED: To eliminate vertical bus and realize low-cost and improvement in reliability and vibration resistance by arranging an instrument transformer and an arrester at the lower part of the container, and then forming a drawer in the power receiving side at the side surface in the upper part of the container. SOLUTION: An instrument transformer 2 and an arrester 3 are arranged at the lower part within a container 20, and a drawer 21 is formed in the upper and side portion of the container 20. The container 20 accommodates, at its side surface, a grounded switch 4 for line, a circuit breaker 5 for line and an operation box to drive a grounded switch 6 for working. As explained above, since the instrument transformer 2 and arrester 3 are arranged at the lower part of the container 20, the drawer 21 can be arranged at the upper side of the operation box 41. Therefore, operation space of the operation box 41 can be reserved and a horizontal bus 30 can be connected in direct to the drawer 21. Accordingly, the vertical bus arranged to reserve the operation space can be eliminated and a low cost, highly reliable and small size gas insulated breaker using a less number of parts can be attained.
