PLC是現(xiàn)代工業(yè)的三大支柱之一,是可靠性高、應(yīng)用非常廣泛的工業(yè)控制產(chǎn)品。在中大型模塊化的PLC產(chǎn)品中,CPU模塊(中央處理器)是PLC的中心。一些重大的工業(yè)生產(chǎn)線往往要求連續(xù)運(yùn)行不能停頓,而可靠性再高的PLC也不能保證故障為零,因此,雙CPU的冗余控制是一種滿足連續(xù)生產(chǎn)要求、提高系統(tǒng)可用性的有效手段。下面以熔鹽爐自控系統(tǒng)為實(shí)例詳述雙CPU冗余控制的實(shí)現(xiàn)方法。
漏電保護(hù)器的主要部件是個(gè)磁環(huán)感應(yīng)器,火線和零線采用并列繞法在磁環(huán)上纏繞幾圈,在磁環(huán)上還有個(gè)次級線圈.當(dāng)同一相的火線和零線在正常工作時(shí),電流產(chǎn)生的磁通正好抵銷,在次級線圈不會感應(yīng)出電壓.如果某一線有漏電,或未接零線,在磁環(huán)中通過的火線和零線的電流就會不平衡,而產(chǎn)生穿過磁環(huán)的磁通,在次級線圈中感應(yīng)出電壓,通過電磁鐵使脫扣器動作跳閘.電器布置圖可按電氣控制系統(tǒng)的復(fù)雜程度集中繪制或單獨(dú)繪制。但在繪制這類圖形時(shí),機(jī)床輪廓線用細(xì)實(shí)線或點(diǎn)劃線表示,所有能見到的及需表示清楚的電氣設(shè)備,均用粗實(shí)線繪制出簡單的外形輪廓
