Abstract

To provide a switchgear and a ventilation device capable of reducing deterioration of a filter even when the device is installed under an environment where pressure fluctuation is likely to occur.SOLUTION: A switchgear 100 is provided with: a first ventilation port 422 and a second ventilation port 423 that communicate with the inside of a housing 1 of the switchgear 100; a filter 6 that covers the first ventilation port 422; and a door body 7 that openably / closably closes the second ventilation port 423. The door body 7 opens the second ventilation port 423 when the inside of the housing 1 becomes a positive pressure compared to the outside of the housing 1.SELECTED DRAWING: Figure 2
