直流屏用于大中小型發(fā)電廠(chǎng)和變電站，為高壓開(kāi)關(guān)在正常運(yùn)行和故障狀態(tài)下的分合閘、繼電保護(hù)、自動(dòng)控制、開(kāi)關(guān)信號(hào)指示、故障照明等提供直流電源。直流屏的可靠性是其他電源裝置不可替代的，它能滿(mǎn)足變電站和發(fā)電廠(chǎng)這些場(chǎng)合對(duì)電源的高可靠性要求。 </p> <p> 綜保繼電器、控制回路為什么不用交流電： </p> <p> 交流電是交變的，用在控制回路單相控制，正好在分合閘或者故障跳閘情況下那個(gè)點(diǎn)位正好在電勢(shì)0位，那就跳不掉或者合不上; </p> <p>

直流屏是一種全新的數(shù)字化控制、保護(hù)、管理、測(cè)量的新型直流系統(tǒng)。監(jiān)控主機(jī)部分高度集成化，采用單板結(jié)構(gòu)（Allinone），內(nèi)含絕緣監(jiān)察、電池巡檢、接地選線(xiàn)、電池活化、硅鏈穩(wěn)壓、微機(jī)**信號(hào)等功能。主機(jī)配置大液晶觸摸屏，各種運(yùn)行狀態(tài)和參數(shù)均以漢字顯示，整體設(shè)計(jì)方便簡(jiǎn)潔，人機(jī)界面友好，符合用戶(hù)使用習(xí)慣。
