DCS系統(tǒng)接地是為了保證當(dāng)進(jìn)入DCS系統(tǒng)的信號(hào)、供電電源或DCS系統(tǒng)設(shè)備本身出現(xiàn)問(wèn)題時(shí)，有效的接地系統(tǒng)能承受過(guò)載電流并可以迅速將過(guò)載電流導(dǎo)入大地。接地系統(tǒng)能夠?yàn)镈CS提供屏蔽層，消除電子噪聲干擾，并為整個(gè)控制系統(tǒng)提供公共信號(hào)參考點(diǎn)(即參考零電位)。當(dāng)接地系統(tǒng)發(fā)生問(wèn)題時(shí)(接地電阻過(guò)大，多點(diǎn)接地，接地線(xiàn)斷線(xiàn)或接地線(xiàn)與高電壓、大電流設(shè)備相接觸等)，會(huì)造成人員的觸電傷害及設(shè)備的損壞，據(jù)了解，有些電廠DCS系統(tǒng)經(jīng)?！八罊C(jī)” (或不明原因的“死機(jī)”)，大多是因?yàn)榻拥叵到y(tǒng)不良或存在問(wèn)題所引起的。 因此，完善、可靠、正確的接地，是DCS 系統(tǒng)能夠安全、可靠和良好運(yùn)行的關(guān)鍵。
