Abstract

Use: the invention relates to a method and a device for the explosion proofing of instruments and closets containing electrical and electronic apparatus, and can be used in the gas, oil and other industries in which such apparatus is used in explosive environments. The aim of the claimed method is to extend the functional capabilities and the scope of use of explosion-proof equipment. Essence of the invention: the proposed method is based upon the principle of the direct measurement of gas contamination inside a protected object and the switching of power equipment located inside the protected housing depending upon the gas contamination measurement results.
