The explosion -proof type of explosion -proof gourd is the explosion -proof type of its electrical equipment, which is determined by the environmental factors where its electrical equipment is located. In the explosive gas environment, according to the "dangerous place classification" in GB3836.14-2000 and the characteristics of explosion-proof type combined with explosion-proof gourd equipment in Chapter 1 of GB3836.1-2000, the explosion-proof type of explosion-proof gourd electrical equipment can be Utilized: explosion -type "D", the "C" "C" "I" is essentially safe

When the flammable dust environment, according to the 1.3 of 1.3 in GB12476.1-2000, the prevention of ignition is mainly to limit the maximum surface temperature of the shell and use the "dust" or "dust" shell to limit the dust

Example: Explosive gas acetylene (C2H2) Environmental explosion-proof gourd, its motor, switch box (control box) and other electrical parts use explosion-barrier type, and according to the Appendix B of GB3836.1-2000, the explosion-proof level of acetylene is "C" The temperature group is T2, so the explosion -proof logo is: Exdiic2 or Exdiic300 ° C
