</p> <p> 直流系統(tǒng)的組成 </p> <p> 直流系統(tǒng)主要由兩大部份組成。一部份是電池屏，另一部份是直流充電屏（直流屏）。電池屏就是一個(gè)可以擺放多節(jié)電池的機(jī)柜（800×600×2260）。電池屏中的電池一般是由2V-12V的電池以9節(jié)到108節(jié)串聯(lián)方式組成，對(duì)應(yīng)電的電壓輸出也就是110V或220V。目前使用的電池主要是閥控式密封免維護(hù)鉛酸電池。直流屏主要是由機(jī)柜、整流模塊系統(tǒng)、監(jiān)控系統(tǒng)、絕緣監(jiān)測(cè)單元、電池巡檢單元、開(kāi)關(guān)量檢測(cè)單元、降壓?jiǎn)卧耙幌盗械慕涣鬏斎?、直流輸出、電壓顯示、電流顯示等配電單元。樂(lè)山低壓直流屏報(bào)價(jià)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。</p><div

</p> <p> 控制模塊工作狀態(tài)是否正確; </p> <p> 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> 直流屏在卸裝、搬運(yùn)過(guò)程中應(yīng)該設(shè)專人負(fù)責(zé)統(tǒng)一指揮，指揮人員發(fā)出的指揮信號(hào)必須清晰、準(zhǔn)確，搬運(yùn)過(guò)程應(yīng)緩慢移動(dòng)，防止嚴(yán)重的沖擊和震蕩，以免損壞柜體、構(gòu)件或傷人。 </p> <p> 對(duì)于易脫落、難固定或者容易傾倒損壞的門(mén)、屏柜內(nèi)的設(shè)備等，一般應(yīng)拆下分開(kāi)運(yùn)輸。 </p> <p> 直流屏的固定宜采用螺栓連接，應(yīng)注意不得損傷屏體。 </p> <p> 實(shí)施電焊時(shí)，應(yīng)注意防止弧光傷害周圍人員的眼睛，必要時(shí)候可在周圍設(shè)置擋光屏。 </p> <p> 在潮濕的地方進(jìn)行電焊工作，焊工必須站在干燥的木板上或穿絕緣鞋。直流屏是蓄電池和智能充電器的完美的統(tǒng)一體，它的自動(dòng)化程度很高功能較多*在電力系統(tǒng)內(nèi)應(yīng)用比較普遍；</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
