雙路雙切設(shè)計(jì)風(fēng)險(xiǎn)

在供電配置上采用雙路自動(dòng)切換電路:一路UPS、一路廠用電，在正常時(shí)兩套同時(shí)供電的方式，如圖2所示。這種設(shè)計(jì)的問題是目前的切換接觸器本身滿足不了需要(圖2中接觸器型號(hào)為L(zhǎng)C1D65008M5)。當(dāng)供電電壓跌落現(xiàn)象發(fā)生后沒有積極采取補(bǔ)救措施，這就使得電能的質(zhì)量沒有保證，也就是說，在系統(tǒng)沖擊時(shí)，電壓跌落(C1其電壓值還沒有到接觸器失壓回位)問題已成為影響電能質(zhì)量的一個(gè)重要因素，廠用電源提供的電源有時(shí)甚至到了供電設(shè)備不能正常工作的范圍，電源系統(tǒng)不能提供可靠有效的供電電源。造成的后果是顯而易見的。
