內容概要
隨著石油、化工、礦業等產業的飛速發展，照明燈具在生產、倉儲、救援中的使用越來越廣泛，品種越來越多。在爆炸性氣體危險場所里如何防止照明燈具事故性爆炸的發生已經成為十分重要的課題。由於照明燈具在工作時不可避免地產生電火花或形成熾熱的表面，它們一旦與生產或救援現場的爆炸性氣體混合物相遇，就會導致爆炸事故的發生，直接危及公民的生命和國家財產安全。因此，作為使用最廣泛的照明燈具，它的防爆技術問題早已引起了人們的普遍關注和高度重視。採用鋁合金外殼，表面噴塑;照明、應急兩用; 內裝免維護鎳鎘電池組、在正常供電下自動充電，事故斷電或停電對應急燈自動點亮;鋼管布線;應急專用燈中正常照明和應急照明各自獨立;照明應急兩用燈、正常照明和應急照明公用一個燈體，光源獨立。
㈡ 防爆燈EXnCnR什麼意思
㈢ 防爆燈和普通燈的區別是什麼
防爆燈來是指用於可燃性氣體和粉塵源存在的危險場所，能防止燈內部可能產生的電弧、火花和高溫引燃周圍環境里的可燃性氣體和粉塵，從而達到防爆要求的燈具。
普通燈具達不到這個效果。
防爆燈，要求較多。密封，外殼的材料，燈珠，電源，鋁基板等，要求較嚴格，而且還有防爆認證
㈣ 防爆燈具用英語怎麼說
防爆燈具
[詞典]
[化] explosion-proof lamp;
[例句]GB1444-1987防爆燈具專用螺口式燈座
Edison screw lampholders specially used for explosion-proof luminaires
㈤ 各種類型防爆燈代號是什麼
廠家不一樣，型號也不盡相同。 大約有BCD -200隔爆型防爆燈 BGL-200是增安型防爆燈 FGL-200增安型防爆防腐專燈 FGL-G不銹鋼屬防爆燈 BXL-100防爆吸頂燈 等等，。。。。。。。。。。還有防爆投光燈。防爆視孔燈。防爆馬路燈，防爆平台燈好多好多
採納哦
㈥ 防爆燈bad85-s 的字母是什麼意思
BAD是指防爆燈，85是指設計序號，S是指燈傘，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 防爆燈具是什麼意思為什麼要「防爆」
防爆燈具是來指用於可自燃性氣體和粉塵存在的危險場所，能防止燈內部可能產生的電弧、火花和高溫引燃周圍環境里的可燃性氣體和粉塵，從而達到防爆要求的燈具。主要有隔爆型防爆燈具、安全型防爆燈具、移動型防爆燈具等。
防爆的原因：
很多生產場所都會產生某些可燃性物質。如煤礦井下約有三分之二的場所有存在爆炸性物質;化學工業中，約有80%以上的生產車間區域存在爆炸性物質。而生產過程中大量使用電氣儀表，各種磨擦的電火花、機械磨損火花、靜電火花、高溫等不可避免,尤其當儀表、電氣發生故障時。同時空氣中的氧氣是無處不在的。
故客觀上很多工業現場滿足爆炸條件。當爆炸性物質與氧氣的混合濃度處於爆炸極限范圍內時，若存在爆炸源，將會發生爆炸。因此採取防爆就顯得很必要了。
