Vim li cas thiaj siv explosion-Proof teeb

Cov Ntaub Ntawv Thov Kev Pab:

Tsuas muab tso rau hauv, “tawg-profo” teeb yog ib hom explosion-proof hluav taws xob siv nyob rau tej thaj chaw uas tawg. Tej thaj chaw no characterized los ntawm qhov muaj flammable gases, vapors, plua plav. Cov khoom hluav taws xob ntsia thiab siv nyob rau hauv tej cheeb tsam no yuav tsum tau ua raws li cov kev cai “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, dhau 80% of the production areas are explosive. Pa oxygen 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. li no, the necessity for explosion-proof measures becomes evident.

Nqi Ua hauj lwm zoo:

One significant reason people hesitate to use explosion-proof lights is their cost. tiam sis, 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. Yog li ntawd, vim, the overall cost-effectiveness of explosion-proof lights is much higher than that of incandescent lights.
