Шэньхай Взрывозащищенный
Область применения:
Проще говоря, “взрывобезопасный” освещение – это вид взрывозащищенного электрооборудования, применяемого во взрывоопасных зонах.. Такие помещения характеризуются наличием легковоспламеняющихся газов., пары, или пыль в воздухе. Электрооборудование, установленное и используемое в этих средах, должно соответствовать требованиям “Code for Design of Electrical Installations in Explosive and Fire Hazardous Environments” (GB50058).
Reason for Necessity:
Many production sites generate combustible substances. About two-thirds of the areas in coal mines are prone to explosions; in the chemical industry, over 80% of the production areas are взрывной. Кислород is omnipresent in the air. Ignition sources from the extensive use of electrical instruments, frictional sparks, mechanical wear sparks, static sparks, and high temperatures are inevitable, especially when instruments and electrical systems malfunction.
Objectively, many industrial sites meet the conditions for explosions. When the concentration of explosive substances in the air reaches the explosive limit and an ignition source is present, an explosion can occur. Следовательно, the necessity for explosion-proof measures becomes evident.
Cost-Effectiveness:
One significant reason people hesitate to use explosion-proof lights is their cost. Однако, a detailed cost-benefit analysis comparing ordinary incandescent lights with explosion-proof lights reveals that the latter has a much longer lifespan. While incandescent lights might be cheaper initially, their shorter lifespan and frequent replacements incur greater maintenance costs. Поэтому, the overall cost-effectiveness of explosion-proof lights is much higher than that of incandescent lights.
