     防爆(bao)(bao)(bao)(bao)電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)是(shi)(shi)具(ju)有防爆(bao)(bao)(bao)(bao)性(xing)(xing)能(neng)(neng)的(de)(de)(de)(de)一類(lei)電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)。采(cai)取(qu)的(de)(de)(de)(de)措施(shi)有：把(ba)電(dian)(dian)(dian)(dian)(dian)氣(qi)設備(bei)罩裝(zhuang)在一個外殼(ke)內(nei)，這(zhe)種外殼(ke)具(ju)有能(neng)(neng)承受內(nei)部爆(bao)(bao)(bao)(bao)炸(zha)(zha)(zha)性(xing)(xing)混(hun)合(he)物的(de)(de)(de)(de)爆(bao)(bao)(bao)(bao)炸(zha)(zha)(zha)壓力，并能(neng)(neng)阻止內(nei)部的(de)(de)(de)(de)爆(bao)(bao)(bao)(bao)炸(zha)(zha)(zha)向外殼(ke)周圍爆(bao)(bao)(bao)(bao)炸(zha)(zha)(zha)性(xing)(xing)混(hun)合(he)物傳播的(de)(de)(de)(de)結構（隔爆(bao)(bao)(bao)(bao)型）；使電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)帶(dai)電(dian)(dian)(dian)(dian)(dian)零部件不可能(neng)(neng)產(chan)生足以引起爆(bao)(bao)(bao)(bao)炸(zha)(zha)(zha)危險(xian)的(de)(de)(de)(de)火花、電(dian)(dian)(dian)(dian)(dian)弧(hu)或(huo)(huo)(huo)危險(xian)溫度(du)，或(huo)(huo)(huo)把(ba)可能(neng)(neng)產(chan)生這(zhe)些現象的(de)(de)(de)(de)帶(dai)電(dian)(dian)(dian)(dian)(dian)零部件與爆(bao)(bao)(bao)(bao)炸(zha)(zha)(zha)性(xing)(xing)混(hun)合(he)物隔斷開，使之(zhi)不能(neng)(neng)相互接觸或(huo)(huo)(huo)達不到具(ju)有爆(bao)(bao)(bao)(bao)炸(zha)(zha)(zha)性(xing)(xing)危險(xian)的(de)(de)(de)(de)程度(du)（增安型、通風(feng)型等）。在各類(lei)有爆(bao)(bao)(bao)(bao)炸(zha)(zha)(zha)性(xing)(xing)危險(xian)的(de)(de)(de)(de)環境(jing)中，正確地選用與各類(lei)設備(bei)配套的(de)(de)(de)(de)防爆(bao)(bao)(bao)(bao)電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)是(shi)(shi)非常重(zhong)要的(de)(de)(de)(de)。

其主要特點是：

⑴功率等級、安(an)裝(zhuang)尺寸(cun)及轉(zhuan)速的對(dui)應關系(xi)與DIN42673一致，同時考慮(lv)到與YB系(xi)列

的(de)繼承性和(he)Y2系列的(de)互換(huan)性，作(zuo)了必要(yao)調整，更加有(you)效(xiao)和(he)適(shi)用(yong)。

⑵全系列采用(yong)F級絕緣，溫升按B級考核(he)。

⑶噪(zao)聲(sheng)限值(zhi)比YB系(xi)(xi)列(lie)低，接近YB系(xi)(xi)列(lie)的I級噪(zao)聲(sheng)，振動(dong)限值(zhi)與YB系(xi)(xi)列(lie)相當(dang)。

⑷外(wai)殼防護等級(ji)提高(gao)到IP55。

⑸全(quan)系列(lie)選用低噪聲(sheng)深溝球軸承，機座中心高(gao)在(zai)180mm以(yi)上電機設注(zhu)排油裝置。

⑹電機散熱片有平(ping)行(xing)水(shui)平(ping)分布和(he)輻射分布兩種，以平(ping)行(xing)水(shui)平(ping)分布為主。
