一(yi)(yi)、防(fang)(fang)爆電(dian)(dian)(dian)機與普通(tong)電(dian)(dian)(dian)機區別：1、防(fang)(fang)爆電(dian)(dian)(dian)機一(yi)(yi)般應用(yong)在易(yi)燃易(yi)爆的(de)場(chang)合。2、防(fang)(fang)爆電(dian)(dian)(dian)機接線(xian)盒的(de)密封較普通(tong)電(dian)(dian)(dian)機要(yao)好。3、防(fang)(fang)爆電(dian)(dian)(dian)機防(fang)(fang)護(hu)等級最低(di)為IP55，而普通(tong)電(dian)(dian)(dian)機有IP23、IP44、IP54、IP55、IP56不等，故而從外形可以分辨出(chu)。4.增安型電(dian)(dian)(dian)機它是(shi)在正常運行條件下不會(hui)產(chan)生電(dian)(dian)(dian)弧、火花或危險高(gao)溫的(de)電(dian)(dian)(dian)機結(jie)構上，再(zai)采取一(yi)(yi)些機械、電(dian)(dian)(dian)氣和熱(re)的(de)保護(hu)措施，使之進一(yi)(yi)步避免在正...
