描述
設備選型在選擇設備時，首先，要選擇有較高抗干擾能力的產(chǎn)品，其包括了電磁兼容性（EMC），尤其是抗外部干擾能力，如：采用浮地技術、隔離性能好的DCS系統(tǒng)；其次，還應了解生產(chǎn)廠給出的抗干擾指標，如：共模抑制比、差模抑制比、耐壓能力、允許在多大電場強度和多高頻率的磁場強度環(huán)境中工作；嚴格按我國的標準（GB／T13926）合理選擇。另外是靠考察其在類似工程中的應用實績。
綜合抗干擾設計主要考慮來自系統(tǒng)外部的幾種抑制措施。主要內(nèi)容包括：對DCS系統(tǒng)及外引線進行屏蔽以防空間輻射電磁干擾；對外引線進行隔離、濾波，特別是動力電纜應分層布置，以防通過外引線引入傳導電磁干擾；正確設計接地點和接地裝置，完善接地系統(tǒng)。另外，還必須利用軟件手段，提高系統(tǒng)的安全可靠性。
