EXPLOSION-PROOF EQUIPMENT

Increasing a size and a weight is avoided while ignition is prevented. An explosion-proof apparatus (10) includes: a frame (11) having a hollow shape; an air supply device (31) capable of maintaining the inside of the frame (11) at pressure higher than certain pressure by supplying gas to the inside...

Zusammenfassung:	Increasing a size and a weight is avoided while ignition is prevented. An explosion-proof apparatus (10) includes: a frame (11) having a hollow shape; an air supply device (31) capable of maintaining the inside of the frame (11) at pressure higher than certain pressure by supplying gas to the inside; an electrical component (21) disposed inside the frame (11); a battery (17) configured to supply power to the electrical component (21); a protective device (18) capable of stopping power supply from the battery (17) to the electrical component (21); a battery housing enclosure (15) being an increased-safety explosion-proof enclosure configured to house the battery (17) therein; and a protective device housing enclosure (16) being a flameproof explosion-proof enclosure configured to house the protective device (18) therein. The explosion-proof apparatus (10) does not include, inside the battery housing enclosure (15), a management device that manages parameters of the battery (17).
