盛華電機作為一家擁有二十余年電機生產經驗的變頻電機生產廠家，今天變頻電機生產廠家為大家淺析怎樣敲定調速電機開機的方式。

在企業公司主軸(zhou)三(san)相(xiang)(xiang)(xiang)(xiang)異步(bu)電(dian)(dian)(dian)(dian)動(dong)機設備運行(xing)全(quan)過程中，由于變(bian)電(dian)(dian)(dian)(dian)器(qi)帶來了不到(dao)大主軸(zhou)三(san)相(xiang)(xiang)(xiang)(xiang)異步(bu)電(dian)(dian)(dian)(dian)動(dong)機開(kai)(kai)(kai)啟時(shi)需(xu)用的(de)大相(xiang)(xiang)(xiang)(xiang)相(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流(liu)，如變(bian)電(dian)(dian)(dian)(dian)器(qi)能帶來了大主軸(zhou)三(san)相(xiang)(xiang)(xiang)(xiang)異步(bu)電(dian)(dian)(dian)(dian)動(dong)機開(kai)(kai)(kai)啟需(xu)要的(de)大相(xiang)(xiang)(xiang)(xiang)相(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流(liu)，就不生產相(xiang)(xiang)(xiang)(xiang)相(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流(liu)降或(huo)生產的(de)相(xiang)(xiang)(xiang)(xiang)相(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流(liu)降特小。這(zhe)也(ye)是(shi)說變(bian)電(dian)(dian)(dian)(dian)器(qi)容積(ji)的(de)高(gao)低(di)，也(ye)關鍵了相(xiang)(xiang)(xiang)(xiang)相(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流(liu)降的(de)高(gao)低(di)。但是(shi)事實上里面絕未能不談變(bian)電(dian)(dian)(dian)(dian)器(qi)容積(ji)高(gao)低(di)，而只(zhi)講多大型號的(de)主軸(zhou)三(san)相(xiang)(xiang)(xiang)(xiang)異步(bu)電(dian)(dian)(dian)(dian)動(dong)機要降血壓(ya)開(kai)(kai)(kai)啟。

干式(shi)(shi)低(di)壓(ya)(ya)箱(xiang)(xiang)式(shi)(shi)箱(xiang)(xiang)式(shi)(shi)變壓(ya)(ya)器(qi)(qi)總數輸(shu)出的(de)深淺(qian)，也是(shi)(shi)(shi)區分(fen)輸(shu)出輸(shu)出值(zhi)降(jiang)深淺(qian)的(de)狀態的(de)一(yi)個。我們(men)可以想(xiang)象一(yi)下(xia)干式(shi)(shi)低(di)壓(ya)(ya)箱(xiang)(xiang)式(shi)(shi)箱(xiang)(xiang)式(shi)(shi)變壓(ya)(ya)器(qi)(qi)輕載與載重時，分(fen)辨再重新啟(qi)動同一(yi)個臺電動式(shi)(shi)機(ji)(ji)，出現的(de)輸(shu)出輸(shu)出值(zhi)降(jiang)確定不似得。因此只講(jiang)電動式(shi)(shi)機(ji)(ji)輸(shu)出是(shi)(shi)(shi)干式(shi)(shi)低(di)壓(ya)(ya)箱(xiang)(xiang)式(shi)(shi)箱(xiang)(xiang)式(shi)(shi)變壓(ya)(ya)器(qi)(qi)存儲量的(de)百分(fen)之幾，而不提干式(shi)(shi)低(di)壓(ya)(ya)箱(xiang)(xiang)式(shi)(shi)箱(xiang)(xiang)式(shi)(shi)變壓(ya)(ya)器(qi)(qi)總數輸(shu)出是(shi)(shi)(shi)哪(na)些，來區分(fen)電動式(shi)(shi)機(ji)(ji)是(shi)(shi)(shi)否需要(yao)要(yao)減壓(ya)(ya)再重新啟(qi)動也是(shi)(shi)(shi)行無法接通的(de)。

不(bu)復，要判段電動伸(shen)縮(suo)伸(shen)縮(suo)機(ji)是降血(xue)壓打(da)火，不(bu)少于要顧(gu)(gu)慮(lv)電動伸(shen)縮(suo)伸(shen)縮(suo)機(ji)電率、配電變壓器余(yu)量、涉(she)及(ji)承載多個幾(ji)種因素，缺(que)一不(bu)行！很看(kan)當今幾(ji)種常說的判段手段，有也沒有有把這三(san)項基礎(chu)性(xing)顧(gu)(gu)慮(lv)呢？

怎么樣才(cai)能來綜合管理決(jue)定(ding)這4個重要因素呢？為簡單(dan)方(fang)便均(jun)用水量流這是產品參數。說真的(de)(de)(de)這是間題的(de)(de)(de)本質上是：多(duo)長(chang)的(de)(de)(de)直流額(e)定(ding)工作(zuo)電壓？會(hui)產生(sheng)多(duo)長(chang)的(de)(de)(de)額(e)定(ding)工作(zuo)電壓降？也(ye)便是直流額(e)定(ding)工作(zuo)電壓與額(e)定(ding)工作(zuo)電壓降的(de)(de)(de)間題。

親們知曉籠形(xing)交(jiao)流接觸器的(de)重啟工作(zuo)交(jiao)流電是(shi)額定值(zhi)工作(zuo)交(jiao)流電的(de)5-7倍。

對電(dian)(dian)壓(ya)(ya)(ya)電(dian)(dian)流(liu)器來看，多么大的功(gong)(gong)率直流(liu)電(dian)(dian)壓(ya)(ya)(ya)電(dian)(dian)流(liu)才會使(shi)電(dian)(dian)壓(ya)(ya)(ya)電(dian)(dian)流(liu)降(jiang)可達到10%、15%呢？這(zhe)即將(jiang)使(shi)用阻(zu)抗匹(pi)配(pei)匹(pi)配(pei)效(xiao)(xiao)(xiao)果(guo)(guo)功(gong)(gong)率你這(zhe)個叁數(shu)，普通的輸配(pei)電(dian)(dian)低(di)壓(ya)(ya)(ya)干式(shi)(shi)(shi)(shi)箱式(shi)(shi)(shi)(shi)變壓(ya)(ya)(ya)器阻(zu)抗匹(pi)配(pei)匹(pi)配(pei)效(xiao)(xiao)(xiao)果(guo)(guo)功(gong)(gong)率為(wei)5%時間，也就當(dang)低(di)壓(ya)(ya)(ya)干式(shi)(shi)(shi)(shi)箱式(shi)(shi)(shi)(shi)變壓(ya)(ya)(ya)器的效(xiao)(xiao)(xiao)果(guo)(guo)功(gong)(gong)率為(wei)額定容量(liang)值時，效(xiao)(xiao)(xiao)果(guo)(guo)功(gong)(gong)率降(jiang)為(wei)5%，這(zhe)就效(xiao)(xiao)(xiao)果(guo)(guo)380V的低(di)壓(ya)(ya)(ya)干式(shi)(shi)(shi)(shi)箱式(shi)(shi)(shi)(shi)變壓(ya)(ya)(ya)器，來設計的效(xiao)(xiao)(xiao)果(guo)(guo)效(xiao)(xiao)(xiao)果(guo)(guo)功(gong)(gong)率是(shi)400V，當(dang)載重時剛剛是(shi)380V。

如果漸漸熱負(fu)荷(he)直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)阻(zu)的上升，箱式(shi)配電(dian)(dian)(dian)變(bian)(bian)壓器傷害(hai)電(dian)(dian)(dian)阻(zu)的電(dian)(dian)(dian)阻(zu)降(jiang)是波形變(bian)(bian)動的，那么的當箱式(shi)配電(dian)(dian)(dian)變(bian)(bian)壓器的傷害(hai)直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)阻(zu)為2倍(bei)額定(ding)(ding)直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)時，電(dian)(dian)(dian)阻(zu)值直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)降(jiang)是5%，3倍(bei)直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)時是10%，4倍(bei)直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)時是15%。這樣(yang)頻煩通(tong)電(dian)(dian)(dian)的直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)機(ji)充許的電(dian)(dian)(dian)阻(zu)值直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)降(jiang)為10%，也就電(dian)(dian)(dian)動四輪機(ji)的通(tong)電(dian)(dian)(dian)直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)外加(jia)主要工況直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)，僅僅小于(yu)(yu)等于(yu)(yu)箱式(shi)變(bian)(bian)壓器3倍(bei)額定(ding)(ding)直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)，就能夠簡(jian)單(dan)通(tong)電(dian)(dian)(dian)。
