對于PLC控制器供電的電源,應(yīng)采用非動(dòng)力線路供電,直接從低壓配電室的主母線上采用線供電。選用隔離變壓器,且變壓器容量應(yīng)比實(shí)際需要大1.2~1.5倍左右,還可在隔離變壓器前加入濾波器。對于變送器和共用信號(hào)儀表供電應(yīng)選擇分布電容小、采用多次隔離和屏蔽及漏感技術(shù)的配電器。
控制器和I/O系統(tǒng)分別由各自的隔離變壓器供電,并與主電路電源分開。PLC控制器的24V直流電源盡量不要給外圍的各類傳感器供電,以減少外圍傳感器內(nèi)部或供電線路短路故障對PLC控制器的干擾。此外,為保證電網(wǎng)饋電不中斷,可采用在線式不間斷供電電源(UPS)供電,UPS具備過壓、欠壓保護(hù)功能、軟件監(jiān)控、與電網(wǎng)隔離等功能,可提高供電的安全可靠性。對于一些重要的設(shè)備,交流供電電路可采用雙路供電系統(tǒng)。
