内容概要
随着石油、化工、矿业等产业的飞速发展，照明灯具在生产、仓储、救援中的使用越来越广泛，品种越来越多。在爆炸性气体危险场所里如何防止照明灯具事故性爆炸的发生已经成为十分重要的课题。由于照明灯具在工作时不可避免地产生电火花或形成炽热的表面，它们一旦与生产或救援现场的爆炸性气体混合物相遇，就会导致爆炸事故的发生，直接危及公民的生命和国家财产安全。因此，作为使用最广泛的照明灯具，它的防爆技术问题早已引起了人们的普遍关注和高度重视。采用铝合金外壳，表面喷塑;照明、应急两用; 内装免维护镍镉电池组、在正常供电下自动充电，事故断电或停电对应急灯自动点亮;钢管布线;应急专用灯中正常照明和应急照明各自独立;照明应急两用灯、正常照明和应急照明公用一个灯体，光源独立。
㈡ 防爆灯EXnCnR什么意思
㈢ 防爆灯和普通灯的区别是什么
防爆灯来是指用于可燃性气体和粉尘源存在的危险场所，能防止灯内部可能产生的电弧、火花和高温引燃周围环境里的可燃性气体和粉尘，从而达到防爆要求的灯具。
普通灯具达不到这个效果。
防爆灯，要求较多。密封，外壳的材料，灯珠，电源，铝基板等，要求较严格，而且还有防爆认证
㈣ 防爆灯具用英语怎么说
防爆灯具
[词典]
[化] explosion-proof lamp;

Edison screw lampholders specially used for explosion-proof luminaires
㈤ 各种类型防爆灯代号是什么
厂家不一样，型号也不尽相同。 大约有BCD -200隔爆型防爆灯 BGL-200是增安型防爆灯 FGL-200增安型防爆防腐专灯 FGL-G不锈钢属防爆灯 BXL-100防爆吸顶灯 等等，。。。。。。。。。。还有防爆投光灯。防爆视孔灯。防爆马路灯，防爆平台灯好多好多
采纳哦
㈥ 防爆灯bad85-s 的字母是什么意思
BAD是指防爆灯，85是指设计序号，S是指灯伞，有需要的。。。。。

2 accident reason analysis
Analysis of gas boiler room the cause of the accident, there are two possible: boiler ontology explosion, boiler room to explode gas explosion concentration and explosions.
Boiler blast furnace body, because be in, or flue gas mixture in explosive existence, when achieved by fire or explosion limit, boiler heat ignites causing accidents in itself. This point and the national norm of building fire system that conform to the relevant provisions. The actual current boiler proct has considered safe proction measures to avoid it. Qualified gas boiler itself has the explosion-proof process design, such as burner in abnormal situation automatic stop, self-control device also stop output fuel, Gas boiler combustion system higher automatization, including the gas pressure is high, low limit alarm protection, when the control logic where step does not meet the conditions set start corresponding interlock protection.
Avoid the boiler exploded possibility, but still ontology exist above another possibility, can avoid? How to avoid it?
Three measures
In fact in design, according to the boiler design code "and" automatic fire alarm system design code "GB50116-1998 etc standard, we have taken the following measures:
Natural gas pipelines valves, meter, may occur gas leak place, boiler room may proce gas storage proct area [relative density 0.8, it is to be in commonly roof area in these areas], all equipped with combustible gas concentration measurement alarm device, according to combustible gas concentration situation give out sound and light alarm signal and start exhaust fan, when leakage accident concentrations reach explosion limit of the lower limit 50% [this value for reference only], but also immediately close natural air intake ct total intake solenoid valves.
In the boiler room and a natural gas pipeline in and out of the room, the incident, but also with the smoke exhaust fan combustible gas alarm interlocking (start).
Electrical, instrument by cable selection TongXin, not less than 1.5 mm2 minimum section.
Gas radiation tube tube top or the nearby, the lightning rod should be installed above the pipe jacking tip should be not less than 3m, and its scope of protection tube top above not less than 1-m.
Gas pipeline should be static grounding device that, when pipeline as metal materials, and lightning protection or electrical engineering protective grounding wire connected, the measured resistance R more than 4 Ω. In pipe joints, such as the bend, flange, valve and pipe with good place cannot metal contact, also with metal soft line will be both ends jumper.
In the boiler room and a natural gas pipeline in and out of the room door, window take pressure measures.
According to the explosion and fire dangerous environment electrical device design specification "the laws 2.2.2 bar, accord with one of the following conditions may, when the explosion danger area: devin in item 3, in the process of proction use fire equipment near, A combination of these several measures can clearly, electrical equipment selection for the explosion.
At the same time according to the explosion and fire dangerous environment electrical device design specification "the laws 2.2.2 bar, accord with one of the following conditions may, when the explosion danger area devin: the first 2 items, and the highest possible flammable explosive chroma does not exceed 10% of the lower limit, Close air intake ct natural total intake solenoid valves, concentration exceed 10% of the lower limit explosion limit, boiler room near the roof area are gas storage proct area, so lighting lamps and lanterns and switch choosing is explosion-proof type.
4 conclusion
In gas boiler room electrical design, lighting choose explosion-proof lamps, other part adopts the explosion-proof type.

㈩ 防爆灯具是什么意思为什么要“防爆”
防爆灯具是来指用于可自燃性气体和粉尘存在的危险场所，能防止灯内部可能产生的电弧、火花和高温引燃周围环境里的可燃性气体和粉尘，从而达到防爆要求的灯具。主要有隔爆型防爆灯具、安全型防爆灯具、移动型防爆灯具等。
防爆的原因：
很多生产场所都会产生某些可燃性物质。如煤矿井下约有三分之二的场所有存在爆炸性物质;化学工业中，约有80%以上的生产车间区域存在爆炸性物质。而生产过程中大量使用电气仪表，各种磨擦的电火花、机械磨损火花、静电火花、高温等不可避免,尤其当仪表、电气发生故障时。同时空气中的氧气是无处不在的。
故客观上很多工业现场满足爆炸条件。当爆炸性物质与氧气的混合浓度处于爆炸极限范围内时，若存在爆炸源，将会发生爆炸。因此采取防爆就显得很必要了。
