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)或者(zhe)一(yi)體柜(ju)(ju),一(yi)般會根(gen)據客(ke)戶的(de)(de)要(yao)求設(she)置。如(ru)(ru)果直流屏(ping)規格(ge)比較大(da)(da),比如(ru)(ru)100AH的(de)(de)直流屏(ping),可能就(jiu)(jiu)需要(yao)做成(cheng)雙(shuang)柜(ju)(ju)的(de)(de),一(yi)個(ge)主機柜(ju)(ju),一(yi)個(ge)電池柜(ju)(ju)。不(bu)過(guo)還有很多(duo)特殊規格(ge)的(de)(de),需要(yao)配的(de)(de)柜(ju)(ju)子數量就(jiu)(jiu)更多(duo),比如(ru)(ru)大(da)(da)型變配電室用的(de)(de)直流屏(ping)柜(ju)(ju)可能包括(kuo)充電柜(ju)(ju)、饋電柜(ju)(ju)、電池柜(ju)(ju)和信號箱。下面為大(da)(da)家講一(yi)下它們的(de)(de)作用分別(bie)是什(shen)么。
1、充電柜
充(chong)電(dian)(dian)柜(ju)在(zai)日常(chang)生活中應用非常(chang)廣泛,我(wo)們涉及較多的(de)(de)就(jiu)是一種將交流(liu)電(dian)(dian)轉換多線路裝置的(de)(de)電(dian)(dian)腦設備。充(chong)電(dian)(dian)柜(ju)廣泛應用在(zai)學(xue)校(xiao)、機關企事業單(dan)(dan)位(wei)、醫院、商場、寫(xie)字樓等集體(ti)單(dan)(dan)位(wei)。充(chong)電(dian)(dian)柜(ju)采用抽屜式結(jie)構設計(ji),方便接(jie)(jie)駁充(chong)電(dian)(dian),無須(xu)人體(ti)直接(jie)(jie)接(jie)(jie)觸市電(dian)(dian),安全性大大提高。柜(ju)內(nei)溫(wen)度(du)達到35℃時,散熱器(qi)自動開啟。很多充(chong)電(dian)(dian)柜(ju)會在(zai)底部安裝移動滑輪,方便搬運和運輸。由(you)此可推理,直流(liu)屏(ping)充(chong)電(dian)(dian)柜(ju),就(jiu)是給直流(liu)屏(ping)電(dian)(dian)池柜(ju)進行充(chong)電(dian)(dian)的(de)(de)充(chong)電(dian)(dian)柜(ju)。
2、饋電柜
饋電(dian)(dian)(dian)(dian)柜(ju)(ju)(ju),從字面上理(li)解(jie),饋,就(jiu)是(shi)送(song)出(chu)的意(yi)思,這(zhe)里(li)可理(li)解(jie)為輸出(chu)、分配的意(yi)思;電(dian)(dian)(dian)(dian),是(shi)電(dian)(dian)(dian)(dian)力;柜(ju)(ju)(ju),就(jiu)是(shi)設備(bei),連起來理(li)解(jie)就(jiu)是(shi)輸出(chu)、分配電(dian)(dian)(dian)(dian)力的設備(bei),也可稱為出(chu)線柜(ju)(ju)(ju)。饋電(dian)(dian)(dian)(dian)是(shi)只向(xiang)負(fu)載(zai)送(song)電(dian)(dian)(dian)(dian)或叫(jiao)供(gong)電(dian)(dian)(dian)(dian),由配電(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)進行分配或聯絡到饋電(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)中,根(gen)據使用環境(jing)的不(bu)同(tong)可將饋電(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)和配電(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)合并在一個柜(ju)(ju)(ju)子,大中型配電(dian)(dian)(dian)(dian)房需(xu)要進行分開設置。
3、電池柜
電(dian)(dian)池(chi)柜(ju)也(ye)可以叫做電(dian)(dian)池(chi)箱,就是由一節或多節電(dian)(dian)池(chi)部件(jian)組成的(de)(de),根據使用(yong)環境(jing)要(yao)求不(bu)同,電(dian)(dian)池(chi)型號也(ye)不(bu)一樣,電(dian)(dian)池(chi)柜(ju)要(yao)求預留出(chu)足(zu)夠(gou)大(da)的(de)(de)容納空(kong)間基(ji)礎(chu)上,還要(yao)保(bao)證滿足(zu)多變的(de)(de)運行環境(jing)。這(zhe)樣可以保(bao)證電(dian)(dian)池(chi)柜(ju)內(nei)的(de)(de)電(dian)(dian)池(chi)得以通風散熱、絕緣、防水、并能夠(gou)大(da)限度(du)的(de)(de)保(bao)護電(dian)(dian)池(chi)免受(shou)碰撞。
4、信號箱
信(xin)號(hao)箱是一個(ge)報警裝置,就是在設(she)(she)備發生故障時,信(xin)號(hao)箱會自動發起警報,告知值班人員馬上處理設(she)(she)置故障,可(ke)分為事故音(yin)響(xiang)(xiang)和預告音(yin)響(xiang)(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;而直流屏是直(zhi)流(liu)電(dian)(dian)(dian)(dian)源柜,通(tong)常(chang)用(yong)交(jiao)流(liu)電(dian)(dian)(dian)(dian)轉變成直(zhi)流(liu)電(dian)(dian)(dian)(dian)配合(he)蓄電(dian)(dian)(dian)(dian)池供電(dian)(dian)(dian)(dian)輸(shu)出,常(chang)有(you)110VDC和(he)220VDC,用(yong)重要設備(bei)的保護和(he)控制用(yong),具(ju)有(you)電(dian)(dian)(dian)(dian)動分合(he)閘、監測保護、故障報警等功(gong)能。
2、PT柜是電(dian)(dian)壓(ya)變換裝置,變配電(dian)(dian)儀表測量和繼電(dian)(dian)保護等(deng)的用(yong)電(dian)(dian),屬一次設備(bei)。直流屏主(zhu)要給開關柜內(nei)執行(xing)設備(bei)提供永恒不間斷直流電(dian)(dian)源,屬二(er)次設備(bei)。
