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(wú)法實(shí)現(xiàn)電動(dòng)機(jī)的過(guò)流、過(guò)載保護(hù)，此時(shí)，需在每臺(tái)電動(dòng)機(jī)側(cè)加熔斷器來(lái)實(shí)現(xiàn)保護(hù)。
3、對(duì)于一些特殊的應(yīng)用場(chǎng)合，如高環(huán)境溫度、高開(kāi)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。
4、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。因此，選擇用于高速電動(dòng)機(jī)的變頻器時(shí)，應(yīng)比普通電動(dòng)機(jī)的變頻器稍大一些。
5、變頻器用于變極電動(dòng)機(jī)時(shí)，應(yīng)充分注意選擇變頻器的容量，使其大額定電流在變頻器的額定輸出電流以下。另外，在運(yùn)行中進(jìn)行極數(shù)轉(zhuǎn)換時(shí)，應(yīng)先停止電動(dòng)機(jī)工作，否則，會(huì)造成電動(dòng)機(jī)空轉(zhuǎn),惡劣時(shí)會(huì)造成變頻器損壞。
6、驅(qū)動(dòng)防爆電動(dòng)機(jī)時(shí)，變頻器沒(méi)有防爆構(gòu)造，應(yīng)將變頻器設(shè)置在危險(xiǎn)場(chǎng)所之外。
以上內(nèi)容便是西門(mén)子變頻器應(yīng)該怎樣選擇的條件以及選擇西門(mén)子變頻器應(yīng)該注意的問(wèn)題。提醒大家不管選擇哪款電力設(shè)備產(chǎn)品，符合自己要求的才是重要。
