電流驟然增大、防爆電機冒煙(yan)、溫(wen)升過高

可能原因：

1.缺相運轉

2.防爆電機過負載、傳動部分被卡住

3.選用(yong)防爆電(dian)機功率過小

4.電源電壓太低(di)或太高

5.防爆電機通風道(dao)阻塞

6.防爆電機局部受(shou)潮絕(jue)緣損壞、繞(rao)組匝間、相間短路

7.離心(xin)開關或電容器損(sun)壞

隔爆型三相(xiang)異步振(zhen)動電機廠家啟動后防(fang)爆電機很快(kuai)發熱，YBZJ隔爆型三相(xiang)異步振(zhen)動電機廠家，甚至燒(shao)毀繞組

可能原因：

1.繞(rao)組匝間(jian)、相(xiang)間(jian)短(duan)路或接地

2.單相電機主、輔繞組相互接(jie)錯(cuo)

3.離心開(kai)關觸點在啟動(dong)后不能斷開(kai)，輔繞(rao)組長(chang)期工作而發熱

處理方法：

1.檢查、修理繞組

2.檢查糾正接線

3.檢查修(xiu)理離心開關

處理方法：

1.檢查電源及線路

2.檢查(cha)工作機(ji)械(xie)及傳動(dong)部(bu)分

3.核實更換電機

4.檢查電源

5.清除阻塞物

6.檢查繞組、修理

7.栓(shuan)查、更換九、啟動后防爆電機很快發(fa)熱，甚至燒毀繞(rao)組
