西門子公司不同類型的變頻器，用戶可以根據(jù)自己的實(shí)際工藝要求和運(yùn)用場合選擇不同類型的變頻器。在選擇變頻器時(shí)因注意以下幾點(diǎn)注意事頊： 1、根據(jù)負(fù)載特性選擇變頻器，如負(fù)載為恒轉(zhuǎn)矩負(fù)載需選擇西門子mmv/mdv、mm420/mm440變頻器，如負(fù)載為風(fēng)機(jī)、泵類負(fù)載應(yīng)選擇西門子430變頻器。 2、選擇變頻器時(shí)應(yīng)以實(shí)際電動(dòng)機(jī)電流值作為變頻器選擇的依據(jù)，電動(dòng)機(jī)的額定功率只能作為參考。另外，應(yīng)充分考慮變頻器的輸出含有豐富的高次諧波，會(huì)使電動(dòng)機(jī)的功率因數(shù)和效率變差。因此，用變頻器給電動(dòng)機(jī)供電與用工頻電網(wǎng)供電相比較，電動(dòng)機(jī)的電流會(huì)增加10%而溫升會(huì)增加20%左右。所以在選擇電動(dòng)機(jī)和變頻器時(shí)應(yīng)考慮到這種情況，適當(dāng)留有余量，以防止溫升過高，影響電動(dòng)機(jī)的使用壽命。 3、變頻器若要長電纜運(yùn)行時(shí)，此時(shí)應(yīng)該采取措施抑制長電纜對(duì)地耦合電容的影響，避免變頻器出力不夠。所以變頻器應(yīng)放大一、兩擋選擇或在變頻器的輸出端安裝輸出電抗器。 4、當(dāng)變頻器用于控制并聯(lián)的幾臺(tái)電動(dòng)機(jī)時(shí)，一定要考慮變頻器到電動(dòng)機(jī)的電纜的長度總和在變頻器的容許范圍內(nèi)。如果超過規(guī)定值，要放大兩擋來選擇變頻器，另外在此種情況下，變頻器的控制方式只能為v/f控制方式，并且變頻器無法實(shí)現(xiàn)電動(dòng)機(jī)的過流、過載保護(hù)，此時(shí)，需在每臺(tái)電動(dòng)機(jī)側(cè)加熔斷器來實(shí)現(xiàn)保護(hù)。 5、對(duì)于一些特殊的應(yīng)用場合，如高環(huán)境溫度、高開關(guān)頻率、高海拔等，此時(shí)會(huì)引起變頻器的降容，變頻器需放大一擋選擇。 6、使用變頻器控制高速電動(dòng)機(jī)時(shí)，由于高速電動(dòng)機(jī)的電抗小，會(huì)產(chǎn)生較多的高次諧波。而這些高次諧波會(huì)使變頻器的輸出電流值增加。
