Giunsa Pagpili ang Explosion-Proof Level sa Explosion-Proof Control Box

Ang mga kahon sa pagkontrol sa blast-proof gi-categorize sa tulo ka lebel: IIA, IIB, ug IIC. Ang lebel sa IIC mas taas ug mas mahal kay sa IIB ug IIA. Daghang mga kostumer ang dili sigurado bahin sa pagpili sa angay nga rating sa pagsabog-proof. Sa pagkatinuod, these ratings correspond to the presence of masunog and explosive gas mixtures in the environment. Pananglitan, hydrogen is classified as IICT1, while carbon monoxide falls under IIAT1; busa, its corresponding control box would be rated IIAT1, although it is typically categorized as IIB. For a comprehensive breakdown of ratings, please consult the “Introduction to Pabuto Mixtures.

Pananglitan:

A workshop needs to install five additional explosion-proof control boxes due to its ethanol production. The required rating for these boxes must meet or exceed IIAT2. Suitable ratings range from IIBT2-6 to IICT2-6, with IIBT4 being frequently utilized.
