一:GZDW直流屏簡介

　　直(zhi)(zhi)流(liu)屏是直(zhi)(zhi)流(liu)電(dian)源(yuan)操作(zuo)系統的(de)(de)簡(jian)稱。通用(yong)(yong)名為(wei)智能免維護直(zhi)(zhi)流(liu)電(dian)源(yuan)屏，簡(jian)稱直(zhi)(zhi)流(liu)屏，通用(yong)(yong)型(xing)號為(wei)GZDW。直(zhi)(zhi)流(liu)屏適(shi)用(yong)(yong)于(yu)(yu)10～500kV變電(dian)站(zhan)、發電(dian)廠和(he)(he)高層建筑、住宅小(xiao)區等的(de)(de)配電(dian)室，以及小(xiao)型(xing)自備發電(dian)廠，作(zuo)為(wei)高壓(ya)開(kai)關、繼電(dian)保護、自動裝置、控(kong)制系統等的(de)(de)操作(zuo)、控(kong)制電(dian)源(yuan)和(he)(he)事故照明電(dian)源(yuan)。同(tong)時也可應用(yong)(yong)于(yu)(yu)其它需要直(zhi)(zhi)流(liu)電(dian)源(yuan)的(de)(de)場(chang)所(如石化、礦山、鐵路(lu)等)。直(zhi)(zhi)流(liu)屏由(you)交直(zhi)(zhi)流(liu)配電(dian)單元(yuan)(yuan)(yuan)、充電(dian)模(mo)塊單元(yuan)(yuan)(yuan)、降壓(ya)硅鏈單元(yuan)(yuan)(yuan)、直(zhi)(zhi)流(liu)饋電(dian)單元(yuan)(yuan)(yuan)、配電(dian)監控(kong)單元(yuan)(yuan)(yuan)、監控(kong)模(mo)塊單元(yuan)(yuan)(yuan)及絕緣監測單元(yuan)(yuan)(yuan)組成。

　　二:直(zhi)流屏工(gong)作原理

　　簡單地說，直(zhi)流屏就是(shi)提供穩定(ding)直(zhi)流電(dian)源的設(she)備。

　　直(zhi)流(liu)屏(ping)兩路(lu)市(shi)電(dian)(dian)(dian)(dian)(dian)經過雙路(lu)交(jiao)流(liu)切換裝置輸入(ru)一路(lu)交(jiao)流(liu)，給(gei)各個充(chong)電(dian)(dian)(dian)(dian)(dian)模塊(kuai)供(gong)電(dian)(dian)(dian)(dian)(dian)。直(zhi)流(liu)屏(ping)充(chong)電(dian)(dian)(dian)(dian)(dian)模塊(kuai)將輸入(ru)三相/單相交(jiao)流(liu)電(dian)(dian)(dian)(dian)(dian)轉換為(wei)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)，給(gei)蓄電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)，同(tong)時給(gei)合閘(zha)負(fu)載供(gong)電(dian)(dian)(dian)(dian)(dian)，另外合閘(zha)母(mu)線通過降壓裝置給(gei)控制母(mu)線供(gong)電(dian)(dian)(dian)(dian)(dian)。當市(shi)電(dian)(dian)(dian)(dian)(dian)斷電(dian)(dian)(dian)(dian)(dian)或異常時,由蓄電(dian)(dian)(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)(dian)(dian)應(ying)急供(gong)電(dian)(dian)(dian)(dian)(dian);

　　直流(liu)屏系統中的(de)各(ge)基礎(chu)監(jian)控(kong)單元受主(zhu)(zhu)監(jian)控(kong)的(de)管理和控(kong)制(zhi)，通(tong)過(guo)通(tong)訊(xun)線將各(ge)基礎(chu)監(jian)控(kong)單元采集的(de)信(xin)息(xi)(xi)(xi)送給主(zhu)(zhu)監(jian)控(kong)統一(yi)管理。主(zhu)(zhu)監(jian)控(kong)顯(xian)示直流(liu)系統各(ge)種(zhong)信(xin)息(xi)(xi)(xi)，用戶也可(ke)觸摸(mo)顯(xian)示屏查詢信(xin)息(xi)(xi)(xi)及操(cao)作，系統信(xin)息(xi)(xi)(xi)還可(ke)以接入到遠程監(jian)控(kong)系統。

　　直流(liu)屏(ping)除基礎的(de)交(jiao)流(liu)監(jian)(jian)控、直流(liu)監(jian)(jian)控、開(kai)關量監(jian)(jian)控外，還可(ke)以(yi)配置絕緣監(jian)(jian)測、電池(chi)巡(xun)檢功能，用來對直流(liu)系統進行全面監(jian)(jian)控。
