विस्फोट रोधी रोशनी का उपयोग क्यों करें?

आवेदन का दायरा:

सीधे शब्दों में कहें, “विस्फोट विरोधी” प्रकाश व्यवस्था एक प्रकार का विस्फोट-रोधी विद्युत उपकरण है जिसका उपयोग विस्फोट जोखिम वाले क्षेत्रों में किया जाता है. ऐसे क्षेत्रों की विशेषता ज्वलनशील गैसों की उपस्थिति है, वाष्प, या हवा में धूल. इन वातावरणों में स्थापित और उपयोग किए जाने वाले विद्युत उपकरणों को आवश्यकताओं को पूरा करना होगा “Code for Design of Electrical Installations in Explosive and Fire Hazardous Environments” (जीबी50058).

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, ऊपर 80% of the production areas are विस्फोटक. ऑक्सीजन 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, विशेष रूप से जब उपकरण और विद्युत प्रणालियाँ ख़राब हो जाती हैं.

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. इस तरह, the necessity for explosion-proof measures becomes evident.

Cost-Effectiveness:

One significant reason people hesitate to use explosion-proof lights is their cost. तथापि, 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. इसलिए, the overall cost-effectiveness of explosion-proof lights is much higher than that of incandescent lights.
