變頻器旁路方式一：手動(dòng)旁路方式
變頻器的手動(dòng)旁路方式，是由3個(gè)高壓隔離開(kāi)關(guān)qs1、qs2和qs3組成，如圖1所示。要求qs2和qs3不能同時(shí)閉合，在機(jī)械上實(shí)現(xiàn)互鎖。變頻運(yùn)行時(shí)，qs1和qs2閉合，qs3斷開(kāi);工頻運(yùn)行時(shí)，qs3閉合，qs1和qs2斷開(kāi)。
變頻器的手動(dòng)旁路方式的優(yōu)點(diǎn)：在檢修變頻器時(shí)，有明顯斷電時(shí)間，能夠保證人身安全，同時(shí)也可手動(dòng)使負(fù)載投入工頻電網(wǎng)運(yùn)行;手動(dòng)旁路可人為判斷故障后再切換，比較安全;造價(jià)低等。
