Shenhai Splużjoni-Prova
Skop ta' Applikazzjoni:
Fi kliem sempliċi, “prova ta' splużjoni” id-dawl huwa tip ta 'tagħmir elettriku kontra l-isplużjoni użat f'żoni b'riskji ta' splużjoni. Żoni bħal dawn huma kkaratterizzati mill-preżenza ta 'gassijiet li jaqbdu, fwar, jew trab fl-arja. Tagħmir elettriku installat u użat f'dawn l-ambjenti għandu jissodisfa r-rekwiżiti tal- “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, fuq 80% of the production areas are splussiv. Ossiġenu 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. Għalhekk, the necessity for explosion-proof measures becomes evident.
Cost-Effectiveness:
One significant reason people hesitate to use explosion-proof lights is their cost. Madankollu, 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. Għalhekk, the overall cost-effectiveness of explosion-proof lights is much higher than that of incandescent lights.
