在現(xiàn)代工業(yè)中,變頻器的應(yīng)用越來越廣泛,但在某些情況下,標(biāo)準(zhǔn)容量的變頻器可能無法滿足實(shí)際需求。這時(shí),就需要考慮加大變頻器的容量。以下是幾種需要加大變頻器容量的典型情況:
1. 變頻器的額定電流偏低當(dāng)變頻器的額定電流小于同容量電動(dòng)機(jī)的額定電流時(shí),應(yīng)根據(jù)電動(dòng)機(jī)的負(fù)載情況選擇大一擋的變頻器。這是因?yàn)樽冾l器需要提供足夠的電流來驅(qū)動(dòng)電動(dòng)機(jī),確保其正常運(yùn)行。
2. 電動(dòng)機(jī)可能短時(shí)間過載電動(dòng)機(jī)在短時(shí)間內(nèi)過載運(yùn)行時(shí),變頻器的過載能力通常為150%,持續(xù)1分鐘。相比之下,電動(dòng)機(jī)的過載時(shí)間可能長達(dá)幾分鐘甚至幾十分鐘。因此,如果電動(dòng)機(jī)可能在短時(shí)間內(nèi)過載運(yùn)行,變頻器的容量應(yīng)加大,以確保其能夠承受這種負(fù)載。
3. 對(duì)加、減速時(shí)間有特殊要求電動(dòng)機(jī)的加速時(shí)間與負(fù)載的慣性大小有關(guān)。例如,對(duì)于慣性較大的負(fù)載,加速時(shí)間可能需要更長,而對(duì)于慣性較小的負(fù)載,加速時(shí)間可能較短。一般說來,對(duì)于需要在重載情況下起動(dòng)和停機(jī)的負(fù)載,在下列情況下,應(yīng)考慮加大變頻器的容量:
(1)要求能夠快速起動(dòng)和停機(jī)者;
(2)點(diǎn)動(dòng)比較頻繁者。
4. 有沖擊負(fù)載當(dāng)電動(dòng)機(jī)與負(fù)載通過離合器結(jié)合時(shí),離合器結(jié)合的瞬間會(huì)產(chǎn)生沖擊負(fù)載,導(dǎo)致電動(dòng)機(jī)轉(zhuǎn)速下降,電流增大,可能觸發(fā)過電流保護(hù)。這種情況下,應(yīng)加大變頻器的容量,以應(yīng)對(duì)沖擊負(fù)載,確保系統(tǒng)穩(wěn)定運(yùn)行。總結(jié)在以下情況下,應(yīng)考慮加大變頻器的容量:
變頻器的額定電流偏低電動(dòng)機(jī)可能短時(shí)間過載對(duì)加、減速時(shí)間有特殊要求存在沖擊負(fù)載通過合理選擇變頻器的容量,可以確保電動(dòng)機(jī)和變頻器的穩(wěn)定運(yùn)行,提高系統(tǒng)的可靠性和效率。
