描述
FCU6-MU042
空間的輻射電磁場（EMI）主要是由電力網(wǎng)絡(luò)、電氣設(shè)備的暫態(tài)過程、雷電、無線電廣播、電視、雷達、高頻感應加熱設(shè)備等產(chǎn)生的，通常稱為輻射干擾，其分布極為復雜。若PLC系統(tǒng)置于所射頻場內(nèi)，就回收到輻射干擾，其影響主要通過兩條路徑：一是直接對PLC內(nèi)部的輻射，由電路感應產(chǎn)生干擾；而是對PLC通信內(nèi)網(wǎng)絡(luò)的輻射，由通信線路的感應引入干擾。輻射干擾與現(xiàn)場設(shè)備布置及設(shè)備所產(chǎn)生的電磁場大小，特別是頻率有關(guān)，一般通過設(shè)置屏蔽電纜和PLC局部屏蔽及高壓泄放元件進行保護。?PLC系統(tǒng)的正常供電電源均由電網(wǎng)供電。由于電網(wǎng)覆蓋范圍廣，它將受到所有空間電磁干擾而在線路上感應電壓和電路。尤其是電網(wǎng)內(nèi)部的變化，入開關(guān)操作浪涌、大型電力設(shè)備起停、交直流傳動裝置引起的諧波、電網(wǎng)短路暫態(tài)沖擊等，都通過輸電線路傳到電源原邊。PLC電源通常采用隔離電源，但其機構(gòu)及制造工藝因素使其隔離性并不理想。實際上，由于分布參數(shù)特別是分布電容的存在，絕對隔離是不可能的。?與PLC控制系統(tǒng)連接的各類信號傳輸線，除了傳輸有效的各類信息之外，總會有外部干擾信號侵入。此干擾主要有兩種途徑：一是通過變送器供電電源或共用信號儀表的供電電源串入的電網(wǎng)干擾，這往往被忽視；二是信號線受空間電磁輻射感應的干擾，即信號線上的外部感應干擾，這是很嚴重的。由信號引入干擾會引起I/O信號工作異常和測量精度大大降低，嚴重時將引起元器件損傷。對于隔離性能差的系統(tǒng)，還將導致信號間互相干擾，引起共地系統(tǒng)總線回流，造成邏輯數(shù)據(jù)變化、誤動和死機。PLC控制系統(tǒng)因信號引入干擾造成I/O模件損壞數(shù)相當嚴重，由此引起系統(tǒng)故障的情況也很多。
