山東變頻電機廠家提醒，對于三相異步電機，定子繞組有三角形和星型兩種接法，星型接法是將三相繞組的尾部連接在一起，三相繞組的頭部與電源相連接。

星(xing)型接(jie)(jie)(jie)法有(you)外(wai)星(xing)接(jie)(jie)(jie)和內星(xing)接(jie)(jie)(jie)幾種條件，內星(xing)接(jie)(jie)(jie)調(diao)速三相異步電(dian)(dian)機(ji)是(shi)將相電(dian)(dian)壓電(dian)(dian)繞阻(zu)(zu)連結接(jie)(jie)(jie)的星(xing)點緊固在定子繞阻(zu)(zu)的適量地方，有(you)四個出(chu)線端(duan)引入(ru)，到外(wai)星(xing)接(jie)(jie)(jie)則是(shi)將相電(dian)(dian)壓電(dian)(dian)繞阻(zu)(zu)的頭與尾所(suo)有(you) 引入(ru)，而在調(diao)速三相異步電(dian)(dian)機(ji)的對外(wai)部(bu)去(qu)接(jie)(jie)(jie)和接(jie)(jie)(jie)線兩(liang)端(duan)。

四角形接法是將某個相線(xian)圈(quan)的頭(tou)(tou)與同一相線(xian)圈(quan)的尾(wei)聯系(xi)即U1連W2，V1連U2，W1連V2，連接方式點與開關(guan)電源接線(xian)頭(tou)(tou)。

山東盛華變頻電機廠家提醒，對于普通三相異步調速電機的，會根據輸出來進行分數段正確處理，調速電機的根據3kW為分界，不多于3kW按星接，3kw之上的交流接觸器按角接，而面對直流變頻空調交流電動機，則按45kW分界，不已經超過45kW按星接，而超過45KW的大功率變頻電機則按角接；而對于起重及冶金電機則按照星接較多，大規格起重電機也會采用角接。

大功率高壓變頻電機其電壓多為3kv/6kv/10kv的額定電流，所以一般都采用星型接線方式，目的是避免大功率高壓變頻電機繞組直接忍(ren)受較(jiao)高的(de)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)直(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)。星形(xing)接法(fa)(fa)中(zhong)，線功率相(xiang)等(deng)于相(xiang)功率，線端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)直(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是相(xiang)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)直(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)根號3倍（半圓(yuan)形(xing)接法(fa)(fa)中(zhong)，線額定(ding)工(gong)(gong)(gong)作電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)瞬(shun)(shun)時(shi)工(gong)(gong)(gong)作感(gan)(gan)應(ying)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)約等(deng)同于相(xiang)額定(ding)工(gong)(gong)(gong)作電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)瞬(shun)(shun)時(shi)工(gong)(gong)(gong)作感(gan)(gan)應(ying)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)而(er)線瞬(shun)(shun)時(shi)工(gong)(gong)(gong)作感(gan)(gan)應(ying)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)約等(deng)同于相(xiang)瞬(shun)(shun)時(shi)工(gong)(gong)(gong)作感(gan)(gan)應(ying)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)的(de)√3倍），如此(ci)交(jiao)流(liu)(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)動機(ji)馬達繞(rao)線所容忍(ren)的(de)額定(ding)工(gong)(gong)(gong)作電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)瞬(shun)(shun)時(shi)工(gong)(gong)(gong)作感(gan)(gan)應(ying)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)相(xiang)對性較(jiao)低。在低壓(ya)(ya)交(jiao)流(liu)(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)動機(ji)中(zhong)，瞬(shun)(shun)時(shi)工(gong)(gong)(gong)作感(gan)(gan)應(ying)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)或許較(jiao)小，而(er)對交(jiao)流(liu)(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)動機(ji)的(de)接地層定(ding)級規范較(jiao)高，如此(ci)選擇星形(xing)接法(fa)(fa)交(jiao)流(liu)(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)動機(ji)的(de)接地層非常好除理，也更(geng)區域經(jing)濟(ji)些。
