Class 1 div 2 lighting<\/strong> in the power plant safety lighting applications<\/strong><\/h1>\n\n\n\n
\"Class<\/figure><\/div>\n\n\n\n

First, why must power plants use professional explosion-proof lights? –Rigid demand in high-risk environments<\/strong><\/strong><\/h2>\n\n\n\n

In this type of power plant involves high temperature and pressure, flammable and explosive substances in a special environment, Class 1 div 2 lighting are the core equipment to ensure safe production. According to the \u201cElectric Power Safety Regulations\u201d requirements, all explosive risk areas must be equipped with Ex d I Mb certified explosion-proof lighting equipment.<\/p>\n\n\n\n

Coal power plant, for example, the fuel storage area methane concentration of about more than the lower explosive limit [LEL] 5%, while the traditional lamps produce 0.02 Joule electric spark can cause an explosion. Class 1 div 2 lighting approved triple protection mechanism to completely eliminate this hidden danger:<\/p>\n\n\n\n

Explosion-proof shell: 8mm thick die-cast aluminum alloy, can withstand an explosion of 15MPa pressure shock<\/p>\n\n\n\n

Intrinsically safe circuit: limit the circuit energy below 0.19mJ minimum ignition energy<\/p>\n\n\n\n

Enhanced safety sealing: joint surface tolerance control within 0.05mm, protection level of IP66 or above<\/p>\n\n\n\n

Actual cases show that a hydropower plant will replace the traditional sodium lamps for 200W LED Class 1 div 2<\/a> lighting, ground illumination increased by 30%, annual energy consumption decreased by 67%, maintenance costs reduced by 82%.<\/p>\n\n\n\n

Second, explosion-proof lights in the power plant core application scenarios – the whole process of risk prevention and control<\/strong><\/strong><\/h2>\n\n\n\n

1 fuel and chemical processing areas<\/strong><\/strong><\/h3>\n\n\n\n

Coal silos, fuel tanks and other places to store a large number of combustible substances, Class 1 div 2 lighting need to have anti-static, corrosion-resistant properties. For example, BAD type Class 1 div 2 lighting adopts WF2 anti-corrosion coating, which can work stably for a long time in the environment of 95% humidity deoxidizer.<\/p>\n\n\n\n

2. Power generation equipment-intensive areas<\/strong><\/strong><\/h3>\n\n\n\n

Boiler room, steam engine room and other high-temperature areas require lamps and lanterns with excellent heat dissipation performance. The latest design of Class 1 div 2 lighting approved aluminum substrate heat conduction + airflow heat sink dual technology, the operating temperature control in the range of -40 \u2103 to +100 \u2103, the light source life extended to 100,000 hours.<\/p>\n\n\n\n

3. Emergency evacuation channel<\/strong><\/strong><\/h3>\n\n\n\n

Explosion-proof emergency lighting system needs to meet the 90-minute continuous power supply guidelines, illuminance is not less than 1lx. intelligent products can be linked to the fire alarm system, automatically switch the emergency mode and mark the escape path.<\/p>\n\n\n\n

Third, the power plant explosion-proof light selection of the 5 Golden Guidelines<\/strong><\/strong><\/h2>\n\n\n\n

1. Certification compliance must be approved CNEX explosion-proof certification + coal safety mark [MA], give priority to IECEx\/ATEX dual-certified products. 2.<\/p>\n\n\n\n

2. Optical performance improvement advocating the selection of 120 \u00b0 wide-angle light distribution + Ra> 90 high color rendering index design, to facilitate equipment inspection. Let’s say a model explosion-proof lights approved nano-prismatic lens to implement uniformity of 0.7 or more.<\/p>\n\n\n\n
