</p> <p> 直流屏常見故障有以下幾點： </p> <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(dāng)檢查三處地方是否正確：a.接線是否正確可靠；b.控制模塊工作狀態(tài)是否正確;c.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。 </p> <p> ③合閘硅整流器或控制硅整流器失電：a.交流進線電源失電會產(chǎn)生合閘硅整流器、控制硅整流器、充電電源同時發(fā)出失電信號，電源恢復(fù)后即可消除；b.直流輸出端空氣開關(guān)脫扣或硅整流器直流輸出端快熔熔斷更換同規(guī)格的快熔或合上空氣開關(guān)，故障消除；c.如若交流電源缺相，直流輸出電壓只能達到額定值的60%-70%，用萬用表測硅整流器輸入端三相電壓即可，處理后便可恢復(fù)正常。 </p><p> 要知道直流屏的基本組成，要先弄清楚什么是直流屏？它是直流電源操作系統(tǒng)的簡稱。通常被稱為智能免維護直流電源屏，直流屏是一種簡稱。它是用來供應(yīng)型號為GZDW的直流電源的。廣泛應(yīng)用在發(fā)電廠和變電站的電力操作系統(tǒng)中，為動力負荷和控制負荷以及直流故障照明負荷等提供直流電源。是當(dāng)代電力系統(tǒng)控制、保護的基礎(chǔ)。 </p> <p> 直流屏由整流模塊系統(tǒng)、配電單元、降壓單元、電池巡檢單元、開關(guān)量檢測單元、監(jiān)控系統(tǒng)、絕緣監(jiān)測單元組成。當(dāng)然也有的是按照交配電單元、充電模塊單元、降壓硅鏈單元、直流饋電單元、配電監(jiān)控單元、監(jiān)控模塊單元及絕緣監(jiān)測單元這七塊來劃分直流屏的功能區(qū)的。還有的是按照由機柜、整流模塊系統(tǒng)、監(jiān)控系統(tǒng)、絕緣監(jiān)測單元、電池巡檢單元、開關(guān)量檢測單元、降壓單元及一系列的交流輸入、直流輸出、電壓顯示、電流顯示等配電單元。不管是哪一種構(gòu)成分類，它們組合在一起，是一個整的直流電源操作系統(tǒng)。所起的作用都是一樣的。直流屏組成：交流電源、整流裝置、充電（穩(wěn)流+穩(wěn)壓）機、蓄電池組、直流配電系統(tǒng)。</p><div
