變頻器制動(dòng)電阻的選擇 在變頻調(diào)速系統(tǒng)中,電機(jī)的降速和停機(jī)是通過逐漸減小頻率來實(shí)現(xiàn)的,在頻率減小的瞬間,電機(jī)的同步轉(zhuǎn)速隨之下降,而由于機(jī)械慣性的原因,電機(jī)的轉(zhuǎn)子轉(zhuǎn)速未變。當(dāng)同步轉(zhuǎn)速小于轉(zhuǎn)子轉(zhuǎn)速時(shí),轉(zhuǎn)子電流的相位幾乎改變了180度,電機(jī)從電動(dòng)狀態(tài)變?yōu)榘l(fā)電狀態(tài);與此同時(shí),電機(jī)軸上的轉(zhuǎn)矩變成了制動(dòng)轉(zhuǎn)矩,使電機(jī)的轉(zhuǎn)速迅速下降,電機(jī)處于再生制動(dòng)狀態(tài)。電機(jī)再生的電能經(jīng)續(xù)流二極管全波整流后反饋到直流電路。由于直流電路的電能無法通過整流橋回饋到電網(wǎng),僅靠變頻器本身的電容吸收,雖然其他部分能消耗電能,但電容仍有短時(shí)間的電荷堆積,形成“泵升電壓”,使直流電壓升高。過高的直流電壓將使各部分器件受到損害。因此,對(duì)于負(fù)載處于發(fā)電制動(dòng)狀態(tài)中必須采取必需的措施處理這部分再生能量。處理再生能量的方法:能耗制動(dòng)和回饋制動(dòng). 能耗制動(dòng)的工作方式 能耗制動(dòng)采用的方法是在變頻器直流側(cè)加放電電阻單元組件,將再生電能消耗在功率電阻上來實(shí)現(xiàn)制動(dòng)。這是一種處理再生能量的直接的辦法,它是將再生能量通過專門的能耗制動(dòng)電路消耗在電阻上,轉(zhuǎn)化為熱能,因此又被稱為“電阻制動(dòng)”,它包括制動(dòng)單元和制動(dòng)電阻二部分。ABB BAILEY SYMPHONY CONTROLS DIGITAL IMASI23 ANALOG INPUT SLAVE MODULE 88255
