id="rxewnrn" class="box"><p><p> 直流屏：直流屏是直流操作電源系統(tǒng)的簡稱。通用名為智能免維護直流電源屏，簡稱直流屏，通用型號為GZDW（G─屏式Z─直流D─電力系統(tǒng)用W─微機監(jiān)控），廣元高壓直流屏。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。 </p> <p> 直流屏的可靠性是其他電源裝置不可替代的，廣元高壓直流屏，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，它為控制負荷和動力負荷以及直流故障照明負荷等提供電源，是當代電力系統(tǒng)控制、保護的基礎(chǔ)，廣元高壓直流屏。配電單元主要是直流屏中為實現(xiàn)交流輸入、直流輸出、電壓顯示、電流顯示等功能所使用的器件。廣元高壓直流屏</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣元高壓直流屏,直流屏" src="https://tyunfile.71360.com/WaterMark/UploadFile/cdjwjd/637299954524335938/6021516.png"></div><p> ①針對各類變電站直流屏，若顯示交流空開跳閘，但并沒有動作。應(yīng)當檢查三處地方是否正確： </p> <p> 接線是否正確可靠； </p> <p> 控制模塊工作狀態(tài)是否正確; </p> <p> 空開狀態(tài)和接點是否正確。 </p> <p> ②有人認為只要保證直流屏進線交流電的供應(yīng)，就可以不用安裝蓄電池，這種想法是不可取的。首先要充分認識到蓄電池是變電站內(nèi)很可靠的直流電源，在變電站交流失電的情況下，蓄電池會給UPS系統(tǒng)、繼電保護設(shè)備、故障照明和監(jiān)控裝置等供電，以達到應(yīng)急的效果。其次蓄電池作為可靠的備用電源，可以彌補電磁開關(guān)合閘時所需的直流電源，防止直流母線電壓瞬間下降而影響繼電保護設(shè)備的正常運行。廣元高壓直流屏屏體的接地及屏內(nèi)的保護接地直接應(yīng)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。</p><div

正常情況下，由充電單元對蓄電池進行充電的同時并向經(jīng)常性負載(繼電保護裝置、控制設(shè)備等)提供直流電源； </p> <p> 當控制負荷或動力負荷需較大的沖擊電流(如斷路器的分、合閘)時，由充電單元和蓄電池共同提供直流電源； </p> <p> 當變電所交流中斷時，由蓄電池組單獨提供直流電源。、 </p> <p> 綜保繼電器、控制回路為什么要用直流而不用交流 </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。 </p><p style="text-indent:25px">直流屏是一種全新的數(shù)字化控制、保護、管理、測量的新型直流系統(tǒng)。監(jiān)控主機部分高度集成化，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、電池活化、硅鏈穩(wěn)壓、微機**信號等功能。主機配置大液晶觸摸屏，各種運行狀態(tài)和參數(shù)均以漢字顯示，整體設(shè)計方便簡潔，人機界面友好，符合用戶使用習(xí)慣。直流屏系統(tǒng)為遠程檢測和控制提供了強大的功能，并具有遙控、遙調(diào)、遙測、遙信功能和遠程通訊接口。通過遠程通訊接口可在遠方獲得直流電源系統(tǒng)的運行參數(shù)，還可通過該接口設(shè)定和修改運行狀態(tài)及定值，滿足電力自動化和電力系統(tǒng)無人值守變電站的要求；配有標準RS232/485串行接口和以太網(wǎng)接口，可方便納入電站自動化系統(tǒng)。直流屏除基礎(chǔ)的交流監(jiān)控、直流監(jiān)控、開關(guān)量監(jiān)控外，還可以配置絕緣監(jiān)測、電池巡檢功能；</p><div
