先(xian)說(shuo)(shuo)說(shuo)(shuo)現今(jin)的(de)4.答(da)案(an)：（沒說(shuo)(shuo)全的(de)請用戶補）

1、電動四輪機工率超過10kW。

2、電動(dong)伸縮機電率達到(dao)50kW。

3、自驅動(dong)力輸(shu)出高于干式(shi)變(bian)壓器功率的20%。

4、經常性再運作時(shi)的(de)三(san)相異(yi)步電機，再運作時(shi)時(shi)導致的(de)的(de)電阻(zu)降高于(yu)10%。

5、忽然(ran)加(jia)載的交流(liu)電(dian)動機，加(jia)載時(shi)有的電(dian)壓值降(jiang)不超15%。

另(ling)外好象(xiang)是個(ge)生產經驗公(gong)試，經由代入(ru)公(gong)試計(ji)算方式(shi)之后(hou)判斷要(yao)不要(yao)穩壓初始化(hua)。望懂得該公(gong)試的小伙(huo)伴填補一(yi)下下。

對1、2四(si)項，雖(sui)然也(ye)沒有利用，實際中100左(zuo)右、數百人Kw的(de)電動三輪機常(chang)有全壓立即打火的(de)。

對3項，電(dian)壓器是輕載嗎?

對4、5項，預期中用又應該(gai)如何把握?誰說是預期估(gu)測嗎?

實際的(de)(de)上采用了減壓(ya)(ya)(ya)啟(qi)用的(de)(de)首要為的(de)(de)，只是(shi)盡量(liang)避免導致別機(ji)器(qi)的(de)(de)正常的(de)(de)的(de)(de)工作。假(jia)若是(shi)沒(mei)有(you)(you)別機(ji)器(qi)，必(bi)須配電(dian)干式(shi)(shi)(shi)(shi)(shi)(shi)干式(shi)(shi)(shi)(shi)(shi)(shi)箱(xiang)(xiang)式(shi)(shi)(shi)(shi)(shi)(shi)變壓(ya)(ya)(ya)器(qi)與智(zhi)能(neng)式(shi)(shi)(shi)(shi)(shi)(shi)四(si)(si)輪(lun)(lun)(lun)機(ji)，那么的(de)(de)智(zhi)能(neng)式(shi)(shi)(shi)(shi)(shi)(shi)四(si)(si)輪(lun)(lun)(lun)機(ji)的(de)(de)有(you)(you)效率(lv)(lv)就能(neng)夠取決于配電(dian)干式(shi)(shi)(shi)(shi)(shi)(shi)干式(shi)(shi)(shi)(shi)(shi)(shi)箱(xiang)(xiang)式(shi)(shi)(shi)(shi)(shi)(shi)變壓(ya)(ya)(ya)器(qi)的(de)(de)工作瓦數，充分注意到有(you)(you)效率(lv)(lv)條(tiao)件(jian)、有(you)(you)效率(lv)(lv)等情況，般智(zhi)能(neng)式(shi)(shi)(shi)(shi)(shi)(shi)四(si)(si)輪(lun)(lun)(lun)機(ji)有(you)(you)效率(lv)(lv)為配電(dian)干式(shi)(shi)(shi)(shi)(shi)(shi)干式(shi)(shi)(shi)(shi)(shi)(shi)箱(xiang)(xiang)式(shi)(shi)(shi)(shi)(shi)(shi)變壓(ya)(ya)(ya)器(qi)工作瓦數的(de)(de)80%，都就能(neng)夠會直接啟(qi)用，一些(xie)配電(dian)干式(shi)(shi)(shi)(shi)(shi)(shi)干式(shi)(shi)(shi)(shi)(shi)(shi)箱(xiang)(xiang)式(shi)(shi)(shi)(shi)(shi)(shi)變壓(ya)(ya)(ya)器(qi)與智(zhi)能(neng)式(shi)(shi)(shi)(shi)(shi)(shi)四(si)(si)輪(lun)(lun)(lun)機(ji)時啟(qi)用。

怎么(me)樣(yang)去 來融合考慮一下這(zhe)多(duo)個(ge)要素呢?為以便(bian)于都(dou)電(dian)費流這(zhe)里參數指標。或許這(zhe)里話題(ti)的實際上是：極(ji)大的功(gong)率(lv)大小(xiao)?會(hui)容易(yi)造成(cheng)極(ji)大的線電(dian)壓(ya)功(gong)率(lv)降?也還是功(gong)率(lv)大小(xiao)與線電(dian)壓(ya)功(gong)率(lv)降的話題(ti)。

大伙懂得籠形無刷(shua)電(dian)機的(de)起動瞬時工作電(dian)流是穩定瞬時工作電(dian)流的(de)5-7倍。
