直接啟動，主(zhu)要用(yong)于(yu)小功率(lv)(lv)的(de)場合。就(jiu)(jiu)是(shi)一個空氣(qi)開(kai)關(guan)，更(geng)簡單的(de)就(jiu)(jiu)是(shi)用(yong)閘刀開(kai)機(ji)，好一點的(de)用(yong)斷路器(qi)。由于(yu)功率(lv)(lv)小，雖然(ran)有突然(ran)大的(de)電流，但對(dui)電網沖擊還能受。我們家庭用(yong)的(de)電扇(shan)，就(jiu)(jiu)是(shi)此類(lei)。

　　直流電機西門子6RA70調速器報警F068修理變頻(pin)啟動(VSD或VFD)，它(ta)(ta)是把臺階化成(cheng)一(yi)個(ge)(ge)斜坡來爬。主要(yao)是通過頻(pin)率的緩慢上升來實現。它(ta)(ta)除了這個(ge)(ge)優點(dian)，還有其它(ta)(ta)優點(dian)。

　　黃線部(bu)分，表(biao)示星(xing)三角(jiao)柜的啟(qi)動過程，先是星(xing)形(xing)(xing)接(jie)法(fa)接(jie)入電(dian)(dian)路中，電(dian)(dian)機(ji)的電(dian)(dian)流突(tu)變一(yi)次，(就是我比喻的“爬臺階(jie)"。)此電(dian)(dian)流只有(you)正常(chang)滿(man)載電(dian)(dian)流的2倍多(duo)。多(duo)少秒后，電(dian)(dian)機(ji)轉動平穩(wen)后，電(dian)(dian)流就降(jiang)下(xia)(xia)來(lai)。接(jie)下(xia)(xia)來(lai)，再(zai)一(yi)次切入三角(jiao)形(xing)(xing)。這個時候，還是有(you)一(yi)個突(tu)變。這個突(tu)變的電(dian)(dian)流，對(dui)電(dian)(dian)機(ji)也有(you)損害。

　　柜(ju)，因為體積大，都是做成落地式的。
