二、高低壓開關柜綜合試驗臺技術指標

1.三相交流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)380V：輸(shu)出三相交流(liu)(liu)相電(dian)(dian)(dian)(dian)壓220V、線電(dian)(dian)(dian)(dian)壓380V，zui大輸(shu)出電(dian)(dian)(dian)(dian)流(liu)(liu)20A。

2.交直(zhi)流控制電源：

①輸出(chu)(chu)三相交(jiao)流電(dian)壓0-690V可調(diao)，zui大輸出(chu)(chu)電(dian)流8A。

    ②輸出直(zhi)流電壓(ya)0-250V可調，zui大輸出電流10A。

    ③輸出三相交流控制(zhi)電(dian)(dian)壓，即額定電(dian)(dian)壓和(he)過電(dian)(dian)壓（UA=UB=UC=220V-275V可調、UAB=UBC=UCA =380V-480V可調），zui大輸出電(dian)(dian)流8A。

        3、 三相交流電(dian)(dian)流：輸出三相交流電(dian)(dian)流0-10A可調，開(kai)口(kou)電(dian)(dian)壓6V。三相電(dian)(dian)流通(tong)過轉換開(kai)關任意(yi)選擇電(dian)(dian)流與電(dian)(dian)壓相角(jiao)分別為(wei)+30º、0º、-30º，即“超前(qian)”（容性負(fu)載(zai)）、“同(tong)相”（阻性負(fu)載(zai)）、“滯后”（感性負(fu)載(zai)）。

操(cao)作(zuo)說明

以檢驗(yan)單相交(jiao)流電壓表為(wei)例：

1、接通輸入(ru)電源AC380V

2、連(lian)接(jie)交流操作電壓(ya)輸(shu)出電源線至(zhi)電壓(ya)表

3、檢查并(bing)確認(ren)接線是(shi)否，接通總電源開(kai)關

4、將調壓器回零，并按(an)“合閘”扭，

5、再按(an)面板上交(jiao)流操(cao)作(zuo)電壓的“合閘”扭

6、緩慢調(diao)節輸出調(diao)節旋扭(niu)，使(shi)電(dian)(dian)壓升到要求值，觀察電(dian)(dian)壓表的情況(kuang)。

7、試驗完畢(bi)后(hou)，先按面板上交(jiao)流操作(zuo)電壓的“分閘”扭(niu),再按面板上總(zong)“分閘”扭(niu)。然后(hou)，斷開總(zong)電源開關
