直流屏的作用就是將交流電變壓-整流，成為直流電，并儲(chǔ)存在蓄電池組中，另外還有直流配電輸出。隨著計(jì)算機(jī)技術(shù)和通信技術(shù)的快速發(fā)展，電力系統(tǒng)逐漸向著綜合自動(dòng)化、網(wǎng)絡(luò)化集中管理以及電站或電廠無人值守的方向發(fā)展。而這種自動(dòng)化系統(tǒng)對(duì)不安全憂患的就需要采取一定的措施。作為電力系統(tǒng)的重要組成部分，直流屏應(yīng)用大量科學(xué)技術(shù)，選擇高性能綜合控制器對(duì)直流屏的每個(gè)運(yùn)行環(huán)節(jié)進(jìn)行監(jiān)控；選擇電池巡檢單元以保證蓄電池（蓄電池可保證系統(tǒng)在斷電情況下或是直流電源系統(tǒng)本身損壞而出現(xiàn)斷電情況下正常運(yùn)作）的電壓正常，如有發(fā)現(xiàn)蓄電池惡化現(xiàn)象，可及時(shí)處理，這樣就算在斷電情況下，仍能向外及時(shí)提供直流電源，避免故障發(fā)生； </p> <p> <br /> </p> <p> <br /> 德陽萬正直流屏批發(fā)商屏體的接地及屏內(nèi)的保護(hù)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 style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="德陽伊頓直流屏廠家,直流屏" src="https://tyunfile.71360.com/WaterMark/UploadFile/cdjwjd/637299954530488281/2197700.png"></div><p> 直流電是通過直流充電機(jī)充電模塊保證的，同時(shí)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(shí)候依然有電能跳開故障所有的開關(guān)，起到一定的保護(hù)作用。 </p> <p> 直流電電勢是穩(wěn)定的，不過零點(diǎn)，在使用中，不管什么時(shí)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(fù)極對(duì)地分別是+110V-110V）這時(shí)候，即使控制回路發(fā)生一點(diǎn)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(yùn)行的情況下，查找直流接地故障，而不影響設(shè)備運(yùn)行。 </p><p> 直流屏有哪些常見故障和好的解決辦法？ </p> <p> 直流屏常見故障有以下幾點(diǎn)： </p> <p> ①針對(duì)各類變電站直流屏，若顯示交流空開跳閘，但并沒有動(dòng)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(diǎn)是否正確。 </p> <p> ②有人認(rèn)為只要保證直流屏進(jìn)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(rèn)識(shí)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(huì)給UPS系統(tǒng)、繼電保護(hù)設(shè)備、故障照明和監(jiān)控裝置等供電，以達(dá)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(bǔ)電磁開關(guān)合閘時(shí)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(hù)設(shè)備的正常運(yùn)行。 </p> <p> ③合閘硅整流器或控制硅整流器失電：a.交流進(jìn)線電源失電會(huì)產(chǎn)生合閘硅整流器、控制硅整流器、充電電源同時(shí)發(fā)出失電信號(hào)，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(dá)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。一般直流屏電源設(shè)備在前期運(yùn)輸過程中，是將屏體與電池分開進(jìn)行包裝的。</p><div
