</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。

<p> 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> <p> 柜的固定及接地應(yīng)可靠，盤(pán)、柜漆層應(yīng)完好、清潔整齊 </p> <p> 電池組安裝作業(yè)程序 </p> <p>

就是電壓調(diào)節(jié)的備用電池 </p> <p> 以前直流裝置得蓄電池分為兩組，一組是基本級(jí)，供正常負(fù)荷時(shí)用，一組為端電池，供故障時(shí)調(diào)節(jié)直流母線電壓用的，比如基本電池用得過(guò)多，造成直流母線的電壓下降過(guò)多時(shí)，通過(guò)調(diào)節(jié)裝置將端電池投上去，維持直流母線的電壓水平。 </p> <p> 現(xiàn)在《DL/T5044-2004電力工程直流系統(tǒng)設(shè)計(jì)技術(shù)規(guī)程〉中：第3款3.0.10端電池terminalbattery:蓄電池組中基本電池子之外的蓄電池 </p> <p>
