交流回路中的電容器投入電網(wǎng)或從電網(wǎng)中切除時(shí),接觸器選擇應(yīng)考慮電容器的合閘沖擊電流。一般地,接觸器的額定電流可按電容器的額定電流的1.5倍選取,型號(hào)選CJ10、CJ20等。
It1相當(dāng)于與轉(zhuǎn)矩成正比的電樞電流),然后模仿直流電動(dòng)機(jī)的控制方法,求得直流電動(dòng)機(jī)的控制量,經(jīng)過相應(yīng)的坐標(biāo)反變換,實(shí)現(xiàn)對(duì)異步電動(dòng)機(jī)的控制。其實(shí)質(zhì)是將交流電動(dòng)機(jī)等效為直流電動(dòng)機(jī),分別對(duì)速度,磁場(chǎng)兩個(gè)分量進(jìn)行獨(dú)立控制。通過控制轉(zhuǎn)子磁鏈,然后分解定子電流而獲得轉(zhuǎn)矩和磁場(chǎng)兩個(gè)分量,經(jīng)坐標(biāo)變換,實(shí)現(xiàn)正交或解耦控制。
