每個部分又包含許多的小部件，高壓柜的部分包括：高壓進線柜、高壓出線柜、高壓環網柜和高壓計量柜，大連plc控制柜主(zhu)要(yao)的作(zuo)用(yong)是用(yong)于電(dian)力系統輸(shu)電(dian)、配(pei)電(dian)、電(dian)能(neng)轉換和(he)控制保護等功能(neng)，電(dian)壓(ya)(ya)(ya)等級在3.6KV ~ 550KV，主(zhu)要(yao)包括高(gao)壓(ya)(ya)(ya)斷路器(qi)，高(gao)壓(ya)(ya)(ya)隔(ge)離(li)開關(guan)，高(gao)壓(ya)(ya)(ya)負(fu)荷開關(guan)，高(gao)壓(ya)(ya)(ya)自動重(zhong)合與分段器(qi)，高(gao)壓(ya)(ya)(ya)操作(zuo)機構等。

    在大多數的(de)(de)箱(xiang)式變電站生產廠家，工程師在通電調試的(de)(de)時(shi)候(hou)是沒有(you)對自己做好足夠(gou)的(de)(de)保護的(de)(de)，不如(ru)沒有(you)佩(pei)戴(dai)手(shou)套、沒有(you)佩(pei)戴(dai)安(an)全帽(mao)等等，特別是在夏天，天氣熱(re)的(de)(de)情(qing)況下，有(you)的(de)(de)調試人員甚(shen)至全身都沒有(you)絕緣(yuan)體(ti)。 

    大連plc控制柜高壓計量柜(ju)有(you)兩個個作用(yong): 一，就是對(dui)用(yong)電的計量，一般這個計量柜(ju)由電力部(bu)門管理。第(di)二，母線(xian)下(xia)降（這個名詞是我從“母線(xian)提升”想到(dao)的），一般電纜(lan)進線(xian)到(dao)進線(xian)隔離柜(ju)后，母線(xian)到(dao)了(le)柜(ju)子上部(bu)，到(dao)計量柜(ju)再從上部(bu)到(dao)下(xia)部(bu)，下(xia)部(bu)到(dao)進線(xian)（斷路(lu)器(qi)）柜(ju)的下(xia)進線(xian)，再到(dao)上部(bu)。 

    大連plc控制柜變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)（Transformer）是利用電(dian)(dian)(dian)磁感應的原理來改變(bian)(bian)(bian)(bian)交(jiao)流(liu)電(dian)(dian)(dian)壓(ya)(ya)(ya)的裝(zhuang)置，主(zhu)要構件是初級(ji)線(xian)圈、次級(ji)線(xian)圈和鐵心(xin)（磁芯）。在電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)設(she)備和無線(xian)電(dian)(dian)(dian)路中，常用作(zuo)升降電(dian)(dian)(dian)壓(ya)(ya)(ya)、匹(pi)配(pei)阻(zu)抗，安全隔離(li)等。主(zhu)要功能有：電(dian)(dian)(dian)壓(ya)(ya)(ya)變(bian)(bian)(bian)(bian)換(huan)、電(dian)(dian)(dian)流(liu)變(bian)(bian)(bian)(bian)換(huan)、阻(zu)抗變(bian)(bian)(bian)(bian)換(huan)、隔離(li)、穩壓(ya)(ya)(ya)（磁飽(bao)和變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)）等。按用途可以(yi)分為(wei)：配(pei)電(dian)(dian)(dian)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、電(dian)(dian)(dian)力變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、全密封變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、組合式(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、干(gan)式(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、油浸式(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、單相變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、電(dian)(dian)(dian)爐變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、整流(liu)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)等。變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)是整個箱式(shi)變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)站的核(he)心(xin)。
