。[Scope of Claim for Utility Model Registration] In a closed power distribution board in which a sheath breaker chamber is provided at the front of the interior of the casing, a load bus chamber is provided at the rear, and a power supply bus chamber is provided at the upper front of the load bus chamber. A partition wall that extends horizontally and vertically is installed at the top of the load bus room so that part of the ceiling is formed by the top plate of the housing, and the voltage transformer is fixed to the ceiling of the transformer room. On the other hand, a pressure relief plate that opens outward is provided on the upper surface of the top panel of the housing that forms the ceiling of the load bus room, and the lower part of the bulkhead is connected to the voltage transformer via a through bushing that penetrates the bulkhead. A first fixed terminal is provided below the first fixed terminal, and a second fixed terminal connected to the load bus in the load bus chamber is provided, and a second fixed terminal is provided below the first fixed terminal and is connected to the inside of a lid that can be opened and closed to the rear of the housing through an insulator. A closed power distribution board characterized in that a power fuse is detachably fixed and first and second fixed terminals and detachable first and second movable terminals are provided at both ends of the power fuse.
