Abstract: The present invention relates to a mini-type automatic aerosol fire suppression apparatus, comprising top cap (1), thermal insulating layer (3), inner cylinder (4), outer cylinder (5), bottom cap (7), sensing element (8), screen (9) and igniter (11), wherein a chemical agent (6) and a cooling layer (10) are installed in the inner cylinder (4), the thermal insulating layer (3) is installed between the inner cylinder (4) and the outer cylinder (5), and the sensing element (8) is designed to sense fire. The volume of the apparatus is not greater than 0.05 m3. Compared to that in the prior art, the apparatus is delicate and easy to install, and is suitable for quick local fire suppression, and can get twice the result with half the effort in such applications.

Abstract: A fire-extinguishing aerosol composition for heavy current electric apparatuses is disclosed, which includes oxidant, combustible, adhesive and additive. The composition of the present invention is characterized in that the oxidant is the mixture of the potassium salt and the strontium salt, in which the content of the potassium salt oxidant is more than 20 mass % to less than or equal to 35 mass % of the total mass of the composition, and the content of the strontium salt oxidant is more than or equal to 30 mass % to less than 48 mass % of the total mass of the composition. In the fire-extinguishing aerosol composition of the present invention, the mean particle diameter of all components is less than or equal to 50 ?m. After quenching the fire in a space with the heavy current electric apparatus, the fire-extinguishing aerosol composition of the present invention can ensure that the insulation resistance of the heavy current electric apparatus is more than or equal to 20 M?.

Abstract: A fire-extinguishing aerosol composition for common electric apparatuses is disclosed, which includes oxidant, combustible, adhesive and additive. The composition of the present invention is characterized in that the oxidant is the mixture of the potassium salt and the strontium salt, in which the content of the potassium salt oxidant is more than or equal to 15 mass % to less than 20 mass % of the total mass of the composition, and the content of the strontium salt oxidant is more than 48 mass % to less than or equal to 52 mass % of the total mass of the composition. In the fire-extinguishing aerosol composition of the present invention, the mean particle diameter of all components is less than or equal to 50 ?m. After quenching the fire in a space with the heavy current electric apparatus, the fire-extinguishing aerosol composition of the present invention can ensure that the insulation resistance of the common electric apparatus is ranged from 20M? to 100M?.
