描述

電源質(zhì)量同樣影響系統(tǒng)的穩(wěn)定運(yùn)行。用于系統(tǒng)的電源既要保證電壓的穩(wěn)定，也要保證在一路電源故障時(shí)，無擾切換至另一路電源，否則會(huì)對(duì)系統(tǒng)工作產(chǎn)生干擾。過程控制處理機(jī)主/備處理機(jī)之間的切換有時(shí)也會(huì)導(dǎo)致干擾。另外，大功率的無線電通信設(shè)備如手機(jī)、對(duì)講機(jī)等在工作時(shí)，極易造成干擾，危及系統(tǒng)運(yùn)行。
根據(jù)以往的DCS使用檢修維護(hù)管理經(jīng)驗(yàn)，應(yīng)采用下列防范措施加強(qiáng)監(jiān)督管理，減少及杜絕DCS運(yùn)行中的故障，提高DCS運(yùn)行水平，防止DCS失靈等事故的發(fā)生。
