Znano je, da so pogoji delovnega okolja električne opreme ključni za njihovo varno uporabo, pri čemer je temperatura okolja pomemben dejavnik za njihovo varno delovanje. Vendar, vsaka električna naprava mora imeti določeno delovno temperaturo okolja. Glede električne opreme, odporne proti eksplozijam, nacionalni standard GB3836.1 “Electrical Apparatus for Explosive Gas Atmospheres Part 1: Splošne zahteve” stipulates an operating temperature range of -20 to +40°C.
If the operating environment temperature of električna oprema, odporna proti eksploziji exceeds this specified range, manufacturers must accurately indicate this temperature range on the product’s nameplate. Nadalje, this information should be clearly Adescribed in relevant user documentation, such as the instruction manual.
It is important to note that when designers set certain performance specifications for a product, they consider the actual operating environmental conditions. If the actual operating environment differs from the designed environment, the product may not achieve its performance specifications and could be severely damaged. Operators should be aware that for explosion-proof electrical equipment, operating in temperatures beyond the specified range might impact some of the explosion-proof safety features.
