为什么要使用防爆灯

适用范围:

简单的说, “防爆” 照明是一种防爆电气设备，用于有爆炸危险的区域. 此类区域的特点是存在易燃气体, 蒸气, 或者空气中的灰尘. 在这些环境中安装和使用的电气设备必须满足以下要求 “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, 超过 80% of the production areas are 爆炸物. 氧 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, 尤其是当仪器和电气系统出现故障时.

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. 因此, the necessity for explosion-proof measures becomes evident.

成本效益:

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