PROBLEM TO BE SOLVED: To provide a discharging device for a closed distribution board which can conduct installation of the discharging port and the discharging passage of a special high voltage apparatus room in an outdoor closed distribution board with a simple structured without generating degraded insulating capability caused by invasion of rainwater into a high voltage part, dewing or the like. SOLUTION: A discharging room 3 is formed in an outdoor closed distribution board, and discharging ports 4a, 5a for opening to the discharging room 3 side is formed at a partition part between a special high voltage bus room 1, a load disconnect switch room 2, and the discharging room 3. A discharging port 7a which opens to the outside is formed at the roof part 9 of the discharging room 3, and the discharging passages of the special high voltage bus room 1 and load disconnect switch room 2 communicating with the outside through the inside of the room 3 are also formed. |
