防爆配電箱用以風險場地，作用很大。大家應當對防爆配電箱有越多的掌握，那樣我們在運用時可以更便捷。下邊，大家將掌握防爆配電箱的**行業標準歸類。

我(wo)國防爆配電(dian)箱標(biao)準(zhun)分類(lei):一類(lei)(IA、IB、IC)、二類(lei)(IIA、IIB、IIIC)、三類(lei)(IIIA、IIIC)

1.煤礦業瓦斯環境(jing)選(xuan)用一級防爆配電箱機器設備(bei)。注(zhu)：**類隔爆型考慮到了(le)地底機器設備(bei)的瓦斯、粉煤打(da)火和額外物理學(xue)保障措施(shi)。

用以(yi)煤礦業電器設(she)備時，除甲(jia)烷氣(qi)(qi)體外，環境中還可帶有(you)別的爆(bao)炸性氣(qi)(qi)體，應(ying)按照相對應(ying)易燃氣(qi)(qi)體的標準開展生產制(zhi)造和檢(jian)測(ce)。電器設(she)備應(ying)相對應(ying)標識(shi)（如Exdi/IIBT3或Exdi/III（NH3））。

2.二級防(fang)爆配電(dian)箱機(ji)器(qi)(qi)設備(bei)用(yong)以煤(mei)礦業(ye)瓦斯之外的爆炸(zha)性氣(qi)體(ti)(ti)(ti)環境(jing)。II類(lei)電(dian)器(qi)(qi)設備(bei)可依(yi)據其(qi)采用(yong)的爆炸(zha)性環境(jing)種(zhong)類(lei)進(jin)一步歸(gui)類(lei)。II類(lei)電(dian)器(qi)(qi)設備(bei)再(zai)次歸(gui)類(lei):IIA:代表(biao)氣(qi)體(ti)(ti)(ti)為丙烷氣(qi)；IIB:代表(biao)氣(qi)體(ti)(ti)(ti)為丁(ding)二烯(xi)；代表(biao)氣(qi)體(ti)(ti)(ti)為氫。

3.II級(ji)防爆(bao)配電(dian)箱機器(qi)設備用以煤礦業之外的爆(bao)炸(zha)性(xing)煙(yan)塵環境。III級(ji)電(dian)器(qi)設備可(ke)依據預(yu)估(gu)爆(bao)炸(zha)性(xing)煙(yan)塵環境的特性(xing)進一步歸類(lei)。III類(lei)防爆(bao)配電(dian)箱再次歸類(lei)：IIIA：易燃斜板沉淀池；期待：導(dao)電(dian)性(xing)煙(yan)塵；IIIC：導(dao)電(dian)性(xing)煙(yan)塵。

防爆(bao)配電箱IIC與IIB的差別。

互聯網防爆(bao)(bao)配電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)的(de)IIC和IIB級(ji)關(guan)鍵依據(ju)防爆(bao)(bao)配電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)的(de)適用(yong)場地(di)開展區(qu)別。IIC地(di)區(qu)應用(yong)的(de)防爆(bao)(bao)配電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)稱之(zhi)為IIC級(ji)防爆(bao)(bao)配電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)，IIB區(qu)域應用(yong)的(de)防爆(bao)(bao)配電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)稱之(zhi)為IIB級(ji)防爆(bao)(bao)配電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)。什么叫IIC環(huan)(huan)境，什么是(shi)IIB環(huan)(huan)境？如今要(yao)我簡易地(di)敘述一下這些人(ren)的(de)環(huan)(huan)境。IIB環(huan)(huan)境中爆(bao)(bao)炸(zha)性氣(qi)(qi)體(ti)的(de)主要(yao)成分有(you)：pe（羥基乙炔氣(qi)(qi)體(ti)）、環(huan)(huan)丙(bing)烷、pe、氰(qing)化氫高爐煤(mei)氣(qi)(qi)、爆(bao)(bao)炸(zha)性氣(qi)(qi)體(ti)等關(guan)鍵構件、氡(dong)氣(qi)(qi)、乙炔氣(qi)(qi)體(ti)、二硫化碳等。依據(ju)爆(bao)(bao)炸(zha)性氣(qi)(qi)體(ti)的(de)水準(zhun)，大家制造的(de)防爆(bao)(bao)配電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)有(you)不一樣的(de)規(gui)定。IIC防爆(bao)(bao)配電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)的(de)防護等級(ji)高過IIB防爆(bao)(bao)配電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)。
