Abstract

An explosion-proof device includes a frame having a hollow shape, the frame housing an electrical component and a battery capable of supplying the electrical component with electric power. A protection device is configured to stop electric supply to the electrical component from the battery, if there is a risk of an explosive atmosphere entering the frame. The battery is housed in an explosion-proof container, within the frame, and thus it is possible to suppress damage to surroundings effectively even in case of ignition of an explosive atmosphere flowing into the frame by the battery.
