星三角啟動(dòng)時(shí)間的確定
計(jì)算公式：
（容量開方×2）+4 （秒）
一、口訣
電機(jī)起動(dòng)星三角，起動(dòng)時(shí)間好整定；
容量開方乘以二，積數(shù)加四單位秒。
電機(jī)起動(dòng)星三角，過載保護(hù)熱元件；
整定電流相電流，容量乘八除以七。
二、容量計(jì)算
發(fā)電機(jī)容量為200KVA時(shí)，計(jì)算KW， 200×0.8＝160KW 0.8為功率因數(shù)（范圍0.7-0.9，通常取0.8），即cosφ＝0.8
（1）、計(jì)算電機(jī)容量
功率KW÷功率因數(shù)0.8，
例如37KW÷0.8＝46.25KVA
（2）、計(jì)算星三角啟動(dòng)轉(zhuǎn)換時(shí)間
46.25開方√2（根號(hào)2）＝6.800735≈6.801 6.801×2+4＝17.602≈17.6秒。
（3）、說明
由于電機(jī)負(fù)荷多種多樣，啟動(dòng)轉(zhuǎn)換時(shí)間需要根據(jù)實(shí)際進(jìn)行調(diào)整，不能一味的套用公式計(jì)算，在實(shí)際中會(huì)出現(xiàn)偏差，甚至因此造成啟動(dòng)失敗！
三、實(shí)際操作時(shí)可以按照以下方法進(jìn)行設(shè)定：
1.空載或負(fù)荷較輕時(shí)，按下啟動(dòng)按鈕后觀測(cè)啟動(dòng)電流，隨著電機(jī)轉(zhuǎn)速上升電流會(huì)逐漸減小，到某一值時(shí)不再下降，此時(shí)即為Y轉(zhuǎn)△的時(shí)間。（保險(xiǎn)起見可以再多加2秒）
2.負(fù)荷較重時(shí)，Y起力矩只有△的1/3，電機(jī)轉(zhuǎn)速達(dá)到一定程度后停止上升，距離額定轉(zhuǎn)速還有一定差距，此時(shí)啟動(dòng)電流往往在額定電流1.2倍以上，這種狀態(tài)下不及時(shí)轉(zhuǎn)換，有害無益！電機(jī)轉(zhuǎn)速可能下降，熱繼電器可能動(dòng)作，造成啟動(dòng)失敗！
四、電機(jī)為什么要采用星三角啟動(dòng)？
星三角啟動(dòng)一般用在較大功率電機(jī)和較重負(fù)載的啟動(dòng)中。目的是為了減小電機(jī)啟動(dòng)時(shí)對(duì)電網(wǎng)產(chǎn)生的沖擊波動(dòng)，從而影響到其他用電設(shè)備的正常工作，電機(jī)全壓?jiǎn)?dòng)時(shí)的電流為額定電流的4-7倍，可見沖擊非常大。對(duì)于電源容量小，負(fù)荷重的電網(wǎng)沖擊尤為嚴(yán)重。
五、Y-△啟動(dòng)過程中，Y接法的實(shí)際含義是什么？
電動(dòng)機(jī)的每相組繞由△接法時(shí)承壓380變?yōu)閅接法時(shí)承壓220，限制了啟動(dòng)電流的同時(shí)，啟動(dòng)力矩也被降低為正常時(shí)1/3左右。電器可能動(dòng)作，造成啟動(dòng)失??！
六、三相異步電動(dòng)機(jī)星三角啟動(dòng)的使用條件
1.當(dāng)負(fù)載對(duì)電動(dòng)機(jī)啟動(dòng)力矩?zé)o嚴(yán)格要求又要限制電動(dòng)機(jī)啟動(dòng)電流且電機(jī)滿足380V/Δ接線條件才能采用星三角啟動(dòng)方法；
2.該方法是：在電機(jī)啟動(dòng)時(shí)將電機(jī)接成星型接線,當(dāng)電機(jī)啟動(dòng)成功后再將電機(jī)改接成三角型接線（通過雙投開關(guān)迅速切換）；
3.因電機(jī)啟動(dòng)電流與電源電壓成正比,此時(shí)電網(wǎng)提供的啟動(dòng)電流只有全電壓?jiǎn)?dòng)電流的1/3 ，因此其啟動(dòng)力矩也只有全電壓?jiǎn)?dòng)力矩的1/3。
星三角啟動(dòng)，屬降壓?jiǎn)?dòng)，是以犧牲功率為代價(jià)來?yè)Q取降低啟動(dòng)電流來實(shí)現(xiàn)的。所以不能一概而輪，以電機(jī)功率的大小來確定是否需采用星三角啟動(dòng)，還的看是什么樣的負(fù)載，一般在需要啟動(dòng)時(shí)負(fù)載輕，運(yùn)行時(shí)負(fù)載重尚可采用星三角啟動(dòng)。
一般情況下鼠籠型電機(jī)的啟動(dòng)電流是運(yùn)行電流的5—7倍，而對(duì)電網(wǎng)的電壓要求一般是正負(fù)10%。為了不形成對(duì)電網(wǎng)電壓過大的沖擊所以要采用星三角啟動(dòng)，一般要求在鼠籠型電機(jī)的功率超過變壓器額定功率的10%時(shí)就要采用星三角啟動(dòng)。只有鼠籠型電機(jī)才采用星三角啟動(dòng)。
七、星三角啟動(dòng)一二次原理圖
八、星三角啟動(dòng)電流計(jì)算如下：
1、星三角啟動(dòng)的電機(jī)（以22KW為例），實(shí)際運(yùn)行必須是三角形運(yùn)行才能達(dá)到額定值，其額定值電流為線電流I=22÷0.38÷1.732÷COSφ=44A左右。而流過電機(jī)各相繞組的相電流（包括為實(shí)現(xiàn)三角形連接的外部電纜，即接觸器至電機(jī)線端的電纜）=線電流÷1.732=25.4A。
2、三角形運(yùn)行的電機(jī)在星形連接運(yùn)行時(shí)，線電流=相電流，由于加在電機(jī)各相繞組的相電壓=線電壓÷1.732=220V，因此線電流=相電流=25.4A，實(shí)際啟動(dòng)電流應(yīng)按25.4A來乘以啟動(dòng)倍數(shù)，而不是按44A來計(jì)算啟動(dòng)電流。
3、電纜的選擇是按負(fù)荷實(shí)際長(zhǎng)期電流選擇的，不是按啟動(dòng)電流選擇的，因此，星三角啟動(dòng)的電纜應(yīng)按25.4A來考慮。但，電源側(cè)的電纜以及控制柜斷路器至接觸器的電纜必須按44A考慮，因?yàn)榱鬟^這段電纜的電流為線電流，只有接觸器后至電機(jī)接線端的電纜才是流過相電流。
4、根據(jù)供電距離、鋪設(shè)方式、鋪設(shè)環(huán)境選擇電纜，一般電纜額定載流量應(yīng)該大于25.4÷0.8=32A，所以可選擇6或10平方毫米的電纜
5、選接觸器時(shí)也要根據(jù)實(shí)際情況選擇，空載不頻繁啟動(dòng)時(shí)，兩個(gè)32A一個(gè)25A接觸器即可，帶負(fù)載啟動(dòng)、頻繁啟動(dòng)或接觸器質(zhì)量較差，應(yīng)適當(dāng)加大接觸器型號(hào)。
電機(jī)三角運(yùn)行，星形啟動(dòng)，啟動(dòng)電流是三角直接啟動(dòng)的1/3。
可以用功率/3/220/功率因數(shù)得三角運(yùn)行電流再以1.5-2.5算出三角的啟動(dòng)電流。在乘1/3就是星型的啟動(dòng)電流。
好象結(jié)果與三角運(yùn)行電流差不多，就以額定電流選接觸器和斷路器好了。
實(shí)際購(gòu)買的星三角啟動(dòng)器的兩個(gè)接觸器是型號(hào)電流一樣大的。就是運(yùn)行額定電流選的。

七、星三角啟動(dòng)一二次原理圖
八、星三角啟動(dòng)電流計(jì)算如下：
1、星三角啟動(dòng)的電機(jī)（以22KW為例），實(shí)際運(yùn)行必須是三角形運(yùn)行才能達(dá)到額定值，其額定值電流為線電流I=22÷0.38÷1.732÷COSφ=44A左右。而流過電機(jī)各相繞組的相電流（包括為實(shí)現(xiàn)三角形連接的外部電纜，即接觸器至電機(jī)線端的電纜）=線電流÷1.732=25.4A。
2、三角形運(yùn)行的電機(jī)在星形連接運(yùn)行時(shí)，線電流=相電流，由于加在電機(jī)各相繞組的相電壓=線電壓÷1.732=220V，因此線電流=相電流=25.4A，實(shí)際啟動(dòng)電流應(yīng)按25.4A來乘以啟動(dòng)倍數(shù)，而不是按44A來計(jì)算啟動(dòng)電流。
3、電纜的選擇是按負(fù)荷實(shí)際長(zhǎng)期電流選擇的，不是按啟動(dòng)電流選擇的，因此，星三角啟動(dòng)的電纜應(yīng)按25.4A來考慮。但，電源側(cè)的電纜以及控制柜斷路器至接觸器的電纜必須按44A考慮，因?yàn)榱鬟^這段電纜的電流為線電流，只有接觸器后至電機(jī)接線端的電纜才是流過相電流。
4、根據(jù)供電距離、鋪設(shè)方式、鋪設(shè)環(huán)境選擇電纜，一般電纜額定載流量應(yīng)該大于25.4÷0.8=32A，所以可選擇6或10平方毫米的電纜
5、選接觸器時(shí)也要根據(jù)實(shí)際情況選擇，空載不頻繁啟動(dòng)時(shí)，兩個(gè)32A一個(gè)25A接觸器即可，帶負(fù)載啟動(dòng)、頻繁啟動(dòng)或接觸器質(zhì)量較差，應(yīng)適當(dāng)加大接觸器型號(hào)。
電機(jī)三角運(yùn)行，星形啟動(dòng)，啟動(dòng)電流是三角直接啟動(dòng)的1/3。
可以用功率/3/220/功率因數(shù)得三角運(yùn)行電流再以1.5-2.5算出三角的啟動(dòng)電流。在乘1/3就是星型的啟動(dòng)電流。
好象結(jié)果與三角運(yùn)行電流差不多，就以額定電流選接觸器和斷路器好了。
實(shí)際購(gòu)買的星三角啟動(dòng)器的兩個(gè)接觸器是型號(hào)電流一樣大的。就是運(yùn)行額定電流選的。
