三相繞線式高壓異步電機的檢查方(fang)法
1、定(ding)子
(1)高(gao)壓(ya)電(dian)機定子(zi)對(dui)地(di)絕(jue)緣值不小于IM。/kv,如6kv高(gao)壓(ya)電(dian)機,定子(zi)對(dui)地(di)絕(jue)緣值應(ying)不小于6M幾,電(dian)工每半月應(ying)用(yong)2勸ov高(gao)壓(ya)搖表(biao)搖測一(yi)次,記(ji)錄其變化(hua)情況,如果(guo)電(dian)機阻值發生較(jiao)大變化(hua)或測量值小于6MO,應(ying)對(dui)電(dian)機進行(xing)徹底檢查或汁劃更換。
(2)電(dian)(dian)(dian)工每(mei)月(yue)應對高(gao)壓電(dian)(dian)(dian)機定子相間直流(liu)電(dian)(dian)(dian)阻用雙(shuang)橋進行(xing)量測(ce),并記(ji)下電(dian)(dian)(dian)阻值,三相電(dian)(dian)(dian)阻不(bu)平衡度(du)不(bu)能超過(guo)5%,如(ru)果超過(guo)此數值,說明電(dian)(dian)(dian)機支組線(xian)圈可能有問題,應進行(xing)徹底檢查或進行(xing)計劃更換(huan)。
2、轉(zhuan)子
(l)崗位(wei)或(huo)電工每天應對電機滑環、碳(tan)刷(shua)(shua)、壓(ya)簧(huang)進行(xing)檢查,滑環無火(huo)花,碳(tan)刷(shua)(shua)長度不小于總長度的1/3,壓(ya)簧(huang)卷無損壞(huai)
(2)電工(gong)每(mei)半(ban)月(yue)應對電機(ji)轉(zhuan)子用洲(zhou)ov低壓搖表搖測一次,轉(zhuan)子對地絕緣(yuan)值(zhi)不小1MQ/kv,如果低于此值(zhi),應對電機(ji)進行徹底檢查或進行計(ji)劃更換〕
3、軸承
(1)清動(dong)耘承(cheng)電(dian)機軸承(cheng)瓦(wa)座崗位侮(wu)小(xiao)時(shi)應檢(jian)查(cha)溫(wen)度(du)l次,運行溫(wen)度(du)正常(chang)為翎一4()℃,4()一5()℃為異常(chang);如果溫(wen)度(du)達(da)到4()-5()℃,要由電(dian)工進行檢(jian)查(cha),最(zui)高溫(wen)度(du)不能超(chao)過(guo)6()℃,超(chao)過(guo)此溫(wen)度(du)應對電(dian)機進行更(geng)(geng)換,另外瓦(wa)座內油(you)(you)每3個月至(zhi)少應更(geng)(geng)換油(you)(you)l次,
(2)滾動(dong)抽承電(dian)機每(mei)3個月應加油l次(ci),德6個月應對軸(zhou)承清冼1次(ci)。軸(zhou)承溫度(du)在運(yun)行中不(bu)能超過(guo)7()℃,超過(guo)此溫度(du)應對電(dian)機進行檢(jian)查或(huo)進行更換,
