Claims

[Scope of utility model registration request]

(1) In a device that has a high-pressure chamber that houses a switching device such as a circuit breaker and a busbar chamber that houses a busbar, etc., a part of the partition plate that separates the high-pressure chamber and the busbar chamber has an opening/closing partition that opens due to internal pressure. A safety device for a closed power distribution board, characterized in that the board is provided with an opening extending over the high pressure chamber, m, and line room, and a safety valve for closing this opening, on the upper part of the closed power distribution board main body.

(2) The opening/closing partition plate has one end pivotally connected to a hinge and the other end engaged and held by a guide.
Safety devices for closed switchboards as described in Section.

(3) The safety device for a closed switchboard according to claim 2, wherein the high pressure chamber and the busbar chamber are each provided with a stopper for an opening/closing partition plate.
