style="font-size:14px;">1）控制回路：具有工頻變頻的手動(dòng)切換，以便在變頻出現(xiàn)故障時(shí)可以手動(dòng)切工頻運(yùn)行，因輸出端不能加電壓，固工頻和變頻要有互鎖。</span> </p> <p> <span style="font-size:14px;">2）主回路：電抗器的作用是防止變頻器產(chǎn)生的高次諧波通過電源的輸入回路返回到電網(wǎng)從而影響其他的受電設(shè)備，需要根據(jù)變頻器的容量大小來決定是否需要加電抗器；濾波器是安裝在變頻器的輸出端，減少變頻器輸出的高次諧波，當(dāng)變頻器到電機(jī)的距離較遠(yuǎn)時(shí)，應(yīng)該安裝濾波器。雖然變頻器本身有各種保護(hù)功能，但缺相保護(hù)卻并不完美，斷路器在主回路中起到過載，缺相等保護(hù)，選型時(shí)可按照變頻器的容量進(jìn)行選擇?？梢杂米冾l器本身的過載保護(hù)代替熱繼電器。</span>
