一、直流屏柜的種類及作用

正常情況下，直流屏都是單柜(ju)或者(zhe)一(yi)(yi)體柜(ju)，一(yi)(yi)般會根據客戶的要求設置。如(ru)果直流屏(ping)規格(ge)比較大，比如(ru)100AH的直流屏(ping)，可(ke)能就(jiu)需要做成雙柜(ju)的，一(yi)(yi)個(ge)(ge)主機(ji)柜(ju)，一(yi)(yi)個(ge)(ge)電池(chi)(chi)柜(ju)。不過還有很多特殊規格(ge)的，需要配的柜(ju)子數量就(jiu)更多，比如(ru)大型變配電室用的直流屏(ping)柜(ju)可(ke)能包括充(chong)電柜(ju)、饋電柜(ju)、電池(chi)(chi)柜(ju)和信號箱。下面為大家講一(yi)(yi)下它們的作用分別是什么(me)。

1、充電柜

充(chong)(chong)電(dian)(dian)柜在日(ri)常生活中應(ying)用(yong)非常廣(guang)泛(fan)，我們涉及較(jiao)多的(de)就(jiu)是一(yi)種將交(jiao)流電(dian)(dian)轉換多線路裝(zhuang)置的(de)電(dian)(dian)腦設備。充(chong)(chong)電(dian)(dian)柜廣(guang)泛(fan)應(ying)用(yong)在學(xue)校(xiao)、機(ji)關企事業單(dan)位(wei)、醫院、商場、寫字樓等集體(ti)單(dan)位(wei)。充(chong)(chong)電(dian)(dian)柜采用(yong)抽屜式(shi)結(jie)構設計，方便接駁充(chong)(chong)電(dian)(dian)，無須人體(ti)直接接觸市電(dian)(dian)，安全性大大提(ti)高。柜內溫(wen)度達到(dao)35℃時(shi)，散熱器自動開啟。很多充(chong)(chong)電(dian)(dian)柜會在底部安裝(zhuang)移動滑(hua)輪，方便搬運和(he)運輸。由此可(ke)推(tui)理，直流屏(ping)充(chong)(chong)電(dian)(dian)柜，就(jiu)是給直流屏(ping)電(dian)(dian)池柜進(jin)行充(chong)(chong)電(dian)(dian)的(de)充(chong)(chong)電(dian)(dian)柜。

2、饋電柜

饋電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)，從字面上(shang)理(li)(li)解(jie)，饋，就(jiu)是(shi)送出(chu)的(de)(de)(de)意思，這里可理(li)(li)解(jie)為輸出(chu)、分配的(de)(de)(de)意思；電(dian)(dian)(dian)(dian)(dian)，是(shi)電(dian)(dian)(dian)(dian)(dian)力；柜(ju)(ju)，就(jiu)是(shi)設備，連(lian)起來理(li)(li)解(jie)就(jiu)是(shi)輸出(chu)、分配電(dian)(dian)(dian)(dian)(dian)力的(de)(de)(de)設備，也可稱為出(chu)線柜(ju)(ju)。饋電(dian)(dian)(dian)(dian)(dian)是(shi)只(zhi)向負載送電(dian)(dian)(dian)(dian)(dian)或(huo)叫供電(dian)(dian)(dian)(dian)(dian)，由配電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)進行分配或(huo)聯絡(luo)到饋電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)中(zhong)，根據使(shi)用(yong)環(huan)境的(de)(de)(de)不同(tong)可將饋電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)和配電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)合并(bing)在(zai)一(yi)個柜(ju)(ju)子(zi)，大中(zhong)型配電(dian)(dian)(dian)(dian)(dian)房需要(yao)進行分開設置。

3、電池柜

電(dian)池(chi)(chi)柜也(ye)可以(yi)叫做電(dian)池(chi)(chi)箱，就是由一節或多節電(dian)池(chi)(chi)部件組成的，根據使用環境要求不(bu)同(tong)，電(dian)池(chi)(chi)型(xing)號也(ye)不(bu)一樣(yang)，電(dian)池(chi)(chi)柜要求預留出足(zu)夠(gou)大(da)的容(rong)納空間(jian)基礎(chu)上，還要保(bao)(bao)證滿足(zu)多變(bian)的運行環境。這樣(yang)可以(yi)保(bao)(bao)證電(dian)池(chi)(chi)柜內(nei)的電(dian)池(chi)(chi)得以(yi)通(tong)風散(san)熱、絕緣、防(fang)水、并能夠(gou)大(da)限(xian)度的保(bao)(bao)護電(dian)池(chi)(chi)免受碰(peng)撞。

4、信號箱

信號(hao)(hao)箱(xiang)是(shi)(shi)一個報警裝置，就是(shi)(shi)在(zai)設(she)備發(fa)生故(gu)障時(shi)，信號(hao)(hao)箱(xiang)會(hui)自(zi)動發(fa)起警報，告(gao)知值班人員馬上處理設(she)置故(gu)障，可分為事故(gu)音響和(he)預告(gao)音響。

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；而直流屏是直(zhi)流(liu)電(dian)源柜，通常用(yong)交流(liu)電(dian)轉變(bian)成(cheng)直(zhi)流(liu)電(dian)配(pei)合蓄電(dian)池供電(dian)輸出，常有110VDC和220VDC，用(yong)重要(yao)設備的保護(hu)(hu)和控制用(yong)，具有電(dian)動分合閘、監測保護(hu)(hu)、故障報(bao)警等功能。

2、PT柜是(shi)電(dian)壓變(bian)換裝置(zhi)，變(bian)配電(dian)儀表測量和繼(ji)電(dian)保護等的(de)用電(dian)，屬一次設備。直(zhi)流屏主要給開關柜內執行設備提(ti)供永恒不間(jian)斷直(zhi)流電(dian)源，屬二次設備。
