一、直流屏柜的種類及作用

正常情況下，直流屏都是單柜(ju)(ju)(ju)(ju)(ju)或(huo)者一(yi)體(ti)柜(ju)(ju)(ju)(ju)(ju)，一(yi)般會(hui)根(gen)據客戶的要(yao)求設置。如果直流屏(ping)(ping)規(gui)格(ge)比較大，比如100AH的直流屏(ping)(ping)，可能就(jiu)需要(yao)做成雙(shuang)柜(ju)(ju)(ju)(ju)(ju)的，一(yi)個(ge)主機柜(ju)(ju)(ju)(ju)(ju)，一(yi)個(ge)電(dian)池(chi)柜(ju)(ju)(ju)(ju)(ju)。不(bu)過還(huan)有很多特殊規(gui)格(ge)的，需要(yao)配的柜(ju)(ju)(ju)(ju)(ju)子數量(liang)就(jiu)更多，比如大型變(bian)配電(dian)室用的直流屏(ping)(ping)柜(ju)(ju)(ju)(ju)(ju)可能包括充電(dian)柜(ju)(ju)(ju)(ju)(ju)、饋電(dian)柜(ju)(ju)(ju)(ju)(ju)、電(dian)池(chi)柜(ju)(ju)(ju)(ju)(ju)和信號箱(xiang)。下(xia)(xia)面為大家講一(yi)下(xia)(xia)它們(men)的作(zuo)用分別是什么。

1、充電柜

充(chong)(chong)電(dian)(dian)柜(ju)(ju)在(zai)日常生活中應用(yong)非常廣泛(fan)，我們涉及較多的(de)就是(shi)一種將(jiang)交流電(dian)(dian)轉換多線路裝置的(de)電(dian)(dian)腦設備。充(chong)(chong)電(dian)(dian)柜(ju)(ju)廣泛(fan)應用(yong)在(zai)學校、機關(guan)企事(shi)業單位、醫(yi)院、商場、寫(xie)字樓等集體(ti)單位。充(chong)(chong)電(dian)(dian)柜(ju)(ju)采用(yong)抽屜(ti)式結構(gou)設計，方(fang)便接駁充(chong)(chong)電(dian)(dian)，無須(xu)人體(ti)直接接觸市電(dian)(dian)，安(an)全性大大提(ti)高。柜(ju)(ju)內溫度達到(dao)35℃時(shi)，散熱器自動(dong)開(kai)啟。很多充(chong)(chong)電(dian)(dian)柜(ju)(ju)會在(zai)底部(bu)安(an)裝移動(dong)滑輪，方(fang)便搬運(yun)和運(yun)輸。由此可推理(li)，直流屏(ping)充(chong)(chong)電(dian)(dian)柜(ju)(ju)，就是(shi)給直流屏(ping)電(dian)(dian)池柜(ju)(ju)進行充(chong)(chong)電(dian)(dian)的(de)充(chong)(chong)電(dian)(dian)柜(ju)(ju)。

2、饋電柜

饋電(dian)(dian)(dian)(dian)柜，從字面上理解，饋，就是(shi)(shi)送出(chu)的意思，這里可理解為(wei)輸(shu)出(chu)、分配(pei)(pei)的意思；電(dian)(dian)(dian)(dian)，是(shi)(shi)電(dian)(dian)(dian)(dian)力；柜，就是(shi)(shi)設備(bei)，連起來理解就是(shi)(shi)輸(shu)出(chu)、分配(pei)(pei)電(dian)(dian)(dian)(dian)力的設備(bei)，也(ye)可稱為(wei)出(chu)線柜。饋電(dian)(dian)(dian)(dian)是(shi)(shi)只向負載送電(dian)(dian)(dian)(dian)或叫供電(dian)(dian)(dian)(dian)，由配(pei)(pei)電(dian)(dian)(dian)(dian)柜進(jin)行(xing)分配(pei)(pei)或聯絡到饋電(dian)(dian)(dian)(dian)柜中(zhong)，根據使(shi)用環境(jing)的不同可將饋電(dian)(dian)(dian)(dian)柜和配(pei)(pei)電(dian)(dian)(dian)(dian)柜合并在一個柜子(zi)，大中(zhong)型配(pei)(pei)電(dian)(dian)(dian)(dian)房需要進(jin)行(xing)分開(kai)設置。

3、電池柜

電(dian)(dian)池柜也(ye)可(ke)以叫做電(dian)(dian)池箱，就(jiu)是由一(yi)節或多(duo)節電(dian)(dian)池部(bu)件組成的，根據使(shi)用環(huan)境(jing)要(yao)(yao)求(qiu)不同，電(dian)(dian)池型(xing)號(hao)也(ye)不一(yi)樣，電(dian)(dian)池柜要(yao)(yao)求(qiu)預(yu)留出足夠(gou)大(da)的容納空間基礎上，還要(yao)(yao)保證滿足多(duo)變的運行環(huan)境(jing)。這樣可(ke)以保證電(dian)(dian)池柜內的電(dian)(dian)池得(de)以通風(feng)散(san)熱、絕(jue)緣、防水、并能夠(gou)大(da)限(xian)度的保護電(dian)(dian)池免受碰撞。

4、信號箱

信(xin)號箱(xiang)(xiang)是(shi)一個報(bao)警裝置(zhi)，就是(shi)在設備發生(sheng)故障時(shi)，信(xin)號箱(xiang)(xiang)會自動(dong)發起警報(bao)，告知值班人(ren)員(yuan)馬上處理設置(zhi)故障，可分為事(shi)故音(yin)響(xiang)和預告音(yin)響(xiang)。

二、直流屏柜和pt柜的區別

1、PT柜是安裝電壓互感器的電柜，是一種高度絕緣的特殊用途的變壓器，通常由高壓變成低壓然后供二次設備顯示，具有觀察、測量、計量的作用；而直流屏是(shi)直流電(dian)源柜，通(tong)常用交流電(dian)轉變成(cheng)直流電(dian)配合(he)蓄電(dian)池供電(dian)輸出，常有110VDC和(he)220VDC，用重要設備的保(bao)護(hu)(hu)和(he)控制(zhi)用，具(ju)有電(dian)動分合(he)閘、監測保(bao)護(hu)(hu)、故障報警等功(gong)能。

2、PT柜是電壓變換裝置(zhi)，變配電儀表測量(liang)和繼電保護等的用電，屬(shu)(shu)一次設備(bei)。直(zhi)流屏(ping)主要給開(kai)關柜內執行設備(bei)提(ti)供永恒不間(jian)斷直(zhi)流電源，屬(shu)(shu)二次設備(bei)。
