Therefore the capacitor that a kind of fireproof, safety will be provided is badly in need of.
Utility model content
The purpose of this utility model is to provide a kind of fire safety capacitor, and this fire safety capacitor can put out flare fast when transshipping burning, prevents the electronic devices and components that flare spreads around to capacitor from causing damage.
To achieve these goals, the utility model provides a kind of fire safety capacitor, and fire safety capacitor comprises base, the inner casing covered by base and the shell being sheathed on inner casing outside, airtight to form cavity by base between inner casing and shell; Wherein, cavity is divided into the first chamber and the second chamber by separating cardboard, is placed with powder extinguishing agent in the first chamber.
Preferably, powder extinguishing agent is one or more in ammonium phosphate salt powder, sodium bicarbonate powder, sodium chloride powder, potassium chloride powder.
Preferably, the inwall being positioned at the second chamber in shell is provided with multiple temperature inductor, and the outer wall of shell is provided with warning device, and warning device is electrically connected with temperature inductor.
Preferably, fire safety capacitor also comprises the thermometer be arranged on outer shell outer wall.
Preferably, be connected in series between multiple temperature inductor and thermometer, warning device.
Preferably, warning device is audible-visual annunciator.
Preferably, the inwall of shell and/or outer wall are provided with many strip reinforcements.
According to technique scheme, casing is located at inner casing outside by the utility model, and use base to make to form cavity between shell and inner casing by airtight for the uncovered position of the two, separation cardboard is set in cavity and cavity is divided into the first chamber and the second chamber, and be placed with powder extinguishing agent in the first chamber.After adopting this structure, the flare once the electric elements overload burning in inner casing is scurried out, separation cardboard burns by flare fast, and the powder extinguishing agent that cardboard is placed just is scattered and puts out flare to burning things which may cause a fire disaster, prevents flare from burning away and spreads the electronic component scaling loss of this capacitor periphery.
Other feature and advantage of the present utility model are described in detail in embodiment part subsequently.
