而控母就是合母經(jīng)過降壓硅鏈（通常2035就是里面有5-7個繼電器進行微降）后的**終電壓一般為220V左右也就是負載**終所需要的直流電 </p> <p> 當然根據(jù)負載的不同需求合母控母都可以拿來用的 </p> <p> 直流屏控母和合母。分別為控制母線和合閘母線?？刂颇妇€提供持續(xù)的，較小負荷的直流電源，合閘母線提供瞬時較大的電源。 </p> <p> <br />

以前直流裝置得蓄電池分為兩組，一組是基本級，供正常負荷時用，一組為端電池，供故障時調(diào)節(jié)直流母線電壓用的，比如基本電池用得過多，造成直流母線的電壓下降過多時，通過調(diào)節(jié)裝置將端電池投上去，維持直流母線的電壓水平。 </p> <p>

直流電是通過直流充電機充電模塊保證的同時并聯(lián)蓄電池保證在故障情況下依然有直流電存在保障故障時候依然有電能跳開故障所有的開關(guān)起到一定的保護作用 </p> <p> 直流電電勢是穩(wěn)定的不過零點，在使用中不管什么時候分合閘都能保證有額定電壓能可靠的分合閘 </p> <p> 使用直流電一般是220V（正負極對地分別是+110V-110V）這時候即使控制回路發(fā)生一點接地現(xiàn)象回路電壓依然是額定依然能保證能可靠分合閘可以在保障運行的情況下查找直流接地故障而不影響設(shè)備運行屏體的接地及屏內(nèi)的保護接地直接應與接地網(wǎng)相連，不得轉(zhuǎn)接，接地使用規(guī)范要求規(guī)格的接地線。西藏低壓直流屏系統(tǒng)</p><p

直流屏用于大中小型發(fā)電廠和變電站，為高壓開關(guān)在正常運行和故障狀態(tài)下的分合閘、繼電保護、自動控制、開關(guān)信號指示、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，它能滿足變電站和發(fā)電廠這些場合對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點位正好在電勢0位，那就跳不掉或者合不上; </p> <p> 如果交流電控制回路發(fā)生短路接地現(xiàn)象,則馬上就不能用了,必須跳開控制開關(guān),要不肯定把控制回路或者控制電纜電器燒壞。西藏低壓直流屏系統(tǒng)</p><p
