Shenhai odolný proti výbuchu
Pôsobnosť:
Jednoducho povedané, “odolný proti výbuchu” osvetlenie je druh elektrického zariadenia do výbušného prostredia používaného v priestoroch s nebezpečenstvom výbuchu. Takéto oblasti sa vyznačujú prítomnosťou horľavých plynov, výpary, alebo prach vo vzduchu. Elektrické zariadenia inštalované a používané v týchto prostrediach musia spĺňať požiadavky “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, cez 80% of the production areas are výbušný. Kyslík 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, najmä pri poruche prístrojov a elektrických systémov.
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. Preto, the necessity for explosion-proof measures becomes evident.
Efektivita nákladov:
One significant reason people hesitate to use explosion-proof lights is their cost. Avšak, 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. Preto, the overall cost-effectiveness of explosion-proof lights is much higher than that of incandescent lights.
