鍋爐房防爆開關箱

Ⅰ 天燃氣鍋爐房內可以有配電櫃嗎

天燃氣鍋爐房內可以安裝配套配電櫃

Ⅱ 各種配電櫃、操作櫃上的各種指示燈表示什麼

各種百配電櫃、操作櫃上的各種指示燈不能一概而論，不過有些比較常用的表示方式度：

1、在配電櫃中紅燈亮問表示電源有電或開關已合閘通電，滅了代表就是沒有電或開關斷開了。

2、操作櫃上紅燈表示回停止作業，綠燈表示開始作業，白燈表示有電。

配電櫃是配電箱的上一級配電設備，其體積較大，其中可以放入較大的電氣設備，所以一般作為中等容量度負荷的配電設備，包括了配電箱、電動機等，其適用知容量在各個工藝領域中有不同，一般在幾個千瓦到幾十個千瓦。

Ⅲ 求一位大俠幫忙把論文翻譯成英文~100分 謝謝 燃氣鍋爐房的電氣防爆設計 摘 要：通過分析燃氣鍋爐房事故原

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.

Ⅳ 天然氣鍋爐房內電氣專業哪些設備需採用防爆型

所有電氣又要用防爆電氣，比如，防爆開關，防爆燈，防爆風機等。來自南陽中天防爆

Ⅳ 機房專用配電櫃是指什麼

配電板（箱）分動力配電板（箱）和照明配電板（箱）、計量箱，是配電系統的末級設備。配電櫃是電動機控制中心的統稱。配電櫃使用在負荷比較分散、迴路較少的場合；電動機控制中心用於負荷集中、迴路較多的場合。它們把上一級配電設備某一電路的電能分配給就近的負荷。這級設備應對負荷提供保護、監視和控制。配電櫃的定義[1]分別是指分動力配電櫃和照明配電櫃、計量櫃等配電系統的末級設備。配電櫃分級（1）一級配電設備，統稱為動力配電中心。它們集中安裝在企業的變電站，把電能分配給不同地點的下級配電設備。這一級設備緊靠降壓變壓器，故電氣參數要求較高，輸出電路容量也較大。（2）二級配電設備，是動力配電櫃和電動機控制中心的統稱。[2]動力配電櫃使用在負荷比較分散、迴路較少的場合；電動機控制中心用於負荷集中、迴路較多的場合。它們把上一級配電設備某一電路的電能分配給就近的負荷。這級設備應對負荷提供保護、監視和控制。（3）末級配電設備總稱為照明動力配電箱。它們遠離供電中心，是分散的小容量配電設備。按結構特徵和用途分類：常用配電櫃主要開關櫃類型：低壓開關櫃有GGD、GCK、GCS、MNS、XLL2低壓配電箱和XGM低壓照明箱。主要區別：GGD是固定式，GCK、GCS、MNS是抽屜櫃。GCK和GCS、MNS櫃抽屜推進機構不同；GCS和MNS櫃最要的區別是GCS櫃只能做單面操作櫃，櫃深800mm，MNS櫃可以做雙面操作櫃，櫃深1000mm。

Ⅷ 常壓開水鍋爐房內是否需要配置防爆配電箱等防爆電氣，尤其是燃燒機的電控箱

需要，防爆防潮

Ⅸ 鍋爐除塵器防爆的注意事項有哪些

1、設來備密閉：當鍋爐除塵器管道與自設備密閉不良時，可能發生因空氣漏入或可燃物泄漏而燃燒爆炸。因此，必須保證設備系統的密閉性。
2、廠房通風:要求管道系統達到絕對密閉是不可能的,所以必須加強廠房通風,以保證車間內可燃物濃度不致達到危險的程度。而且對於因設備發生偶然事故或系統發生運行故障時會散發大量可燃氣體的車間。應設 置事故排風系統,以備急需時使用。
3、加強可燃物濃度的檢測與控制:為防止管道系統內可燃物濃度達到爆炸濃度,應設置必要的檢測儀器,以便經常監視系統工作狀態, 實現自動報警。在系統風量設計時,除考慮滿足凈化要求外,還應校核其中可燃物濃度,必要時加大設 計風量,以保證輸送氣體中可燃物濃度低於爆炸濃度下限。

Ⅹ 鍋爐房通風風機如何做防爆處理

呵呵，這個我知道。首先電機要用防爆的，根據你的防爆等級選配防爆電機，2 電路要有穿線管並且連接緊密不能透氣，接頭要用防爆接線盒，燈要採用防爆燈罩，及防爆開關。
