防爆電機的(de)開(kai)展(zhan)(zhan)情況極好，如今易燃易爆(bao)(bao)的(de)產品有許多，而防爆(bao)(bao)電(dian)機(ji)即是用(yong)(yong)在易燃易爆(bao)(bao)場(chang)所(suo)的(de)，所(suo)以開(kai)展(zhan)(zhan)前(qian)途一(yi)片(pian)光(guang)亮。而礦用(yong)(yong)防爆(bao)(bao)電(dian)機(ji)也是用(yong)(yong)在易爆(bao)(bao)場(chang)所(suo)的(de)，只(zhi)不(bu)過是看它的(de)字面意思。即是限制了地(di)方，即是專門礦山(shan)運用(yong)(yong)。盡(jin)管防爆(bao)(bao)電(dian)機(ji)的(de)開(kai)展(zhan)(zhan)前(qian)途一(yi)片(pian)光(guang)亮，那(nei)礦用(yong)(yong)防爆(bao)(bao)電(dian)機(ji)的(de)開(kai)展(zhan)(zhan)趨勢如何呢?YB2系列(lie)防爆(bao)(bao)電(dian)機(ji)

　　(1) 開(kai)展大(da)(da)功(gong)(gong)率(lv)(lv)電(dian)機：當前世界(jie)上(shang)采煤(mei)機的(de)(de)最(zui)大(da)(da)裝(zhuang)機容(rong)量已(yi)超越(yue)1200kw，其驅(qu)動電(dian)機功(gong)(gong)率(lv)(lv)達(da)600kW;相(xiang)習慣的(de)(de)采區工作(zuo)面刮板輸送機的(de)(de)最(zui)大(da)(da)裝(zhuang)機容(rong)量已(yi)超越(yue)1500kW，其驅(qu)動電(dian)機功(gong)(gong)率(lv)(lv)已(yi)達(da)725kW。國內當前的(de)(de)采煤(mei)機驅(qu)動電(dian)機最(zui)大(da)(da)功(gong)(gong)率(lv)(lv)是(shi)400kW，刮板輸送機驅(qu)動電(dian)機最(zui)大(da)(da)功(gong)(gong)率(lv)(lv)是(shi)315kW。YB2系(xi)列防爆電(dian)機

　　(2) 開展3.3kV、6kV和10kV級電(dian)壓(ya)的礦用(yong)電(dian)機：這是由于(yu)遍及歸(gui)納機械化采(cai)煤機組后采(cai)區走向加(jia)長，致(zhi)使電(dian)壓(ya)降增大(da)，一起大(da)功率電(dian)機的運用(yong)也需求(qiu)進步電(dian)壓(ya)等級。YB2系(xi)列防爆電(dian)機

　　(3) 開(kai)(kai)展礦用雙速電機(ji)：為了習慣煤礦輸(shu)送機(ji)低速起動(dong)和高速運轉的工作需要(yao)，國外(wai)礦用刮板(ban)輸(shu)送機(ji)都(dou)是選用雙速電機(ji)驅(qu)動(dong)的。但當(dang)前國產礦用雙速電機(ji)的功率規模、功能指標及配套操控開(kai)(kai)關(guan)的功能等與國外(wai)先進水平相比均有必定距離。YB2系列防爆電機(ji)

　　(4) 進步(bu)礦用(yong)電(dian)(dian)機的(de)(de)可靠性：礦用(yong)防爆電(dian)(dian)機的(de)(de)工況條件(jian)較(jiao)差(cha)，電(dian)(dian)機頻(pin)繁大(da)(da)負荷起動(dong)、負荷改變(bian)大(da)(da)、電(dian)(dian)壓動(dong)搖大(da)(da)、環(huan)境溫度高且有必(bi)定的(de)(de)腐蝕(shi)性等，這(zhe)些都影響電(dian)(dian)機的(de)(de)運用(yong)可靠性和壽數。YB2系列防爆電(dian)(dian)機
