It sets；Fire extinguishing storehouse and air duct bottom are additionally provided with fire extinguishing plate, and fire extinguishing plate plate face is equipped with one group of extinguishing chemical hole arranged in a ring, extinguishing chemical
Hole is in horn-like；Fire extinguishing plate plate face is additionally provided with one group of fan-shaped air-guiding hole arranged in a ring, and fan-shaped air-guiding hole is located at extinguishing chemical hole
Outside is simultaneously corresponded with extinguishing chemical hole respectively；Fan-shaped air-guiding hole is located at air duct bottom, and extinguishing chemical hole is located at fire extinguishing orlop portion, goes out
Sealing film is equipped between fiery storehouse and extinguishing chemical hole；The extinguishing device further includes the battery for providing power supply.
Further, the battery periphery is coated with fireprotection layer.
The utility model has the beneficial effects that：
The flame and smog when fire are separately detected using photosensitive sensor and smoke sensor device, triggering ignition draws
Quick-fried sodium azide, sodium azide generates high pressure nitrogen after being detonated, after nitrogen breaks through isolated film, in a part of punching press fire extinguishing storehouse
Extinguishing chemical, sprayed by extinguishing chemical hole after making extinguishing chemical breaching seal film, another part nitrogen pass through air duct by fan-shaped wind-guiding
Hole is sent out, and still has gas secondary injection, extinguishing effect more preferable after so that extinguishing chemical is ejected；Independent battery is arranged to be supplied
Electricity avoids fire power-off that extinguishing device is caused to fail；It is completely independent between this extinguishing device and switchgear, not by switch cabinet state
Influence.
