電(diàn)抗器(qì)

■産品概述productoverview

變頻(pín)器(qì)制(zhì)動時(shí)所産生(shēng)的(de)再生(shēng)能(néng)量回饋到(dào)×電(diàn)網，并加以利用(yòng)，但(dàn)是(shì)整流單元是(shì)IGBT,會(huì)産生(shēng)較多(dΩuō)的(de)高(gāo)次諧波電(diàn)流，進而會(huì)對(duì)電(diàn)網污染。所以在變頻≤(pín)器(qì)的(de)
前端加上(shàng)能(néng)量回饋電(diàn)抗器(qì)和(hé)濾波器(qì)組合以改善電(diàn)能(néng)質量。

The regenerative energy generated during the braking of the frequenoy conve<rter is fed back tothe power grid and utilized,but therectifier uni is an IGBT,which generaΩtes a large amount of high-order harmonic curent,thereby polluting the power ‍grid.So,anenergy feedback reactor and iter combination are added at thefrontend of the frequ<ency converterto improve power quality.
