蓄電池組運(yùn)行狀態(tài)的檢查并清理：a,若有蓄電池漏液現(xiàn)象，應(yīng)及時(shí)查找原因并處理，以免影響蓄電池的絕緣；b.電池液面若遠(yuǎn)離上液面線，應(yīng)及時(shí)補(bǔ)加蒸餾水；c.充浮狀態(tài)下，蓄電池是不發(fā)熱的，若有發(fā)熱現(xiàn)象應(yīng)及時(shí)處理;d.檢查蓄電池組的連接點(diǎn)，接觸是否嚴(yán)密，有無(wú)氧化，并涂些凡士林油。

直流屏有哪些常見(jiàn)故障和好的解決辦法？ </p> <p> 直流屏常見(jiàn)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(kāi)跳閘，但并沒(méi)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(kāi)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(kāi)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(kāi)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(kāi)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(wàn)用表測(cè)硅整流器輸入端三相電壓即可，處理后便可恢復(fù)正常。直流屏系統(tǒng)為遠(yuǎn)程檢測(cè)和控制提供了強(qiáng)大的功能，并具有遙控、遙調(diào)、遙測(cè)、遙信功能和遠(yuǎn)程通訊接口。</p><div

直流電是通過(guò)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(kāi)故障所有的開(kāi)關(guān)，起到一定的保護(hù)作用； </p> <p> 直流電電勢(shì)是穩(wěn)定的，不過(guò)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。直流屏由整流模塊系統(tǒng)、配電單元、降壓?jiǎn)卧?、電池巡檢單元、開(kāi)關(guān)量檢測(cè)單元、監(jiān)控系統(tǒng)、絕緣監(jiān)測(cè)單元組成。西藏高壓直流屏批發(fā)商</p><p
