Shenhai, odporen na eksplozije
Zasilna razsvetljava za eksplozijsko varna okolja vključuje predvsem razsvetljavo v stanju pripravljenosti, varnostna razsvetljava, evakuacijska razsvetljava, in zasilno reševalno razsvetljavo. Pri izbiri izdelkov, it’s crucial to choose with care. Spodaj, opisujemo ključne parametre za vsako vrsto zasilne razsvetljave, vključno s stopnjami osvetlitve, preklopni časi, in trajanje neprekinjenega napajanja.
1. Standby Lighting:
Standby lighting is used temporarily in case of normal lighting failure due to malfunctions.
Illumination: Should not be less than 10% of the standard lighting levels. In critical areas like high-rise building fire control rooms, pump rooms, smoke extraction rooms, distribution rooms, and emergency power rooms, standby lighting must ensure normal operations.
Switch-over Time: Should not exceed 15 sekund, and for business premises, it should be less than 1.5 sekund.
Connection Time: Typically not less than 20-30 minutes for production workshops, with communication hubs and substations requiring connection until normal lighting is restored. High-rise fire control centers generally require 1-2 ure.
2. Safety Lighting:
Safety lighting is designed to ensure the safety of individuals in hazardous situations following the failure of regular lighting.
Illumination: Na splošno, it should not fall below 5% of normal lighting levels. For particularly hazardous areas, it must not be less than 10%. Medical and emergency care areas, such as emergency centers and operating rooms, require standard illumination levels.
Switch-over Time: Must not exceed 0.5 sekund.
Continuous Power Duration: Determined as needed, typically around 10 minutes for workshops and several hours for operating rooms.
3. Evacuation Lighting:
Evacuation lighting is activated to facilitate safe evacuation in case of an incident leading to normal lighting failure.
Illumination: Not less than 0.5 lux; if using fluorescent lights, the brightness should be appropriately increased.
Switch-over Time: Not more than 1 drugo.
Continuous Power Duration: At least 20 minutes for battery-powered systems, and for buildings over 100m high, at least 30 minut.
4. Emergency Rescue Lighting:
Emergency lighting refers to the systems used by factories, businesses, and public institutions under special circumstances.
Illumination: Varies based on the site environment and scope of use, with different luminous flux levels selected to meet emergency lighting needs.
Lastnosti: Most emergency lighting devices are explosion-proof, vodoodporen, and corrosion-resistant, functioning well in harsh conditions, including corrosive environments, heavy rain, and dusty settings, and are highly resistant to impacts and vibrations.
