1、高壓(ya)柜：

高(gao)壓(ya)(ya)(ya)配(pei)電(dian)(dian)(dian)(dian)柜(ju)又可稱為高(gao)壓(ya)(ya)(ya)開(kai)關柜(ju)，是指用于電(dian)(dian)(dian)(dian)力系統發電(dian)(dian)(dian)(dian)、輸電(dian)(dian)(dian)(dian)、配(pei)電(dian)(dian)(dian)(dian)、電(dian)(dian)(dian)(dian)能轉(zhuan)換(huan)和(he)消(xiao)耗中(zhong)起通(tong)斷(duan)(duan)、控制(zhi)或保護等作(zuo)(zuo)用，電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)等級在3.6kV~550kV的(de)電(dian)(dian)(dian)(dian)器產品，主要包括高(gao)壓(ya)(ya)(ya)斷(duan)(duan)路器、高(gao)壓(ya)(ya)(ya)隔(ge)離開(kai)關與(yu)接地開(kai)關、高(gao)壓(ya)(ya)(ya)負荷開(kai)關、高(gao)壓(ya)(ya)(ya)自(zi)動重合(he)與(yu)分段器，高(gao)壓(ya)(ya)(ya)操作(zuo)(zuo)機構、高(gao)壓(ya)(ya)(ya)防爆配(pei)電(dian)(dian)(dian)(dian)裝置和(he)高(gao)壓(ya)(ya)(ya)開(kai)關柜(ju)等幾(ji)大(da)類。高(gao)壓(ya)(ya)(ya)開(kai)關制(zhi)造業是輸變電(dian)(dian)(dian)(dian)設(she)備制(zhi)造業的(de)重要組成部分，在整個電(dian)(dian)(dian)(dian)力工業中(zhong)占有非常重要的(de)地位。

2、高壓計量柜

一般(ban)都裝設專用(yong)的高(gao)壓(ya)電(dian)能(neng)(neng)計量(liang)(liang)柜，供(gong)電(dian)能(neng)(neng)計量(liang)(liang)用(yong)，即所謂(wei)的高(gao)供(gong)高(gao)計方(fang)式

3、變壓器

變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)（Transformer）是利用(yong)電(dian)(dian)(dian)(dian)磁(ci)感應的(de)原(yuan)理來改變(bian)(bian)(bian)(bian)(bian)交流(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)裝置，主要(yao)構(gou)件是初(chu)級線圈、次級線圈和鐵心（磁(ci)芯(xin)）。在電(dian)(dian)(dian)(dian)器(qi)(qi)設備和無線電(dian)(dian)(dian)(dian)路中(zhong)，常用(yong)作升降電(dian)(dian)(dian)(dian)壓(ya)(ya)、匹配阻(zu)抗(kang)，安全隔離(li)等。主要(yao)功能有：電(dian)(dian)(dian)(dian)壓(ya)(ya)變(bian)(bian)(bian)(bian)(bian)換(huan)、電(dian)(dian)(dian)(dian)流(liu)變(bian)(bian)(bian)(bian)(bian)換(huan)、阻(zu)抗(kang)變(bian)(bian)(bian)(bian)(bian)換(huan)、隔離(li)、穩(wen)壓(ya)(ya)（磁(ci)飽和變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)）等。按用(yong)途可以分為：配電(dian)(dian)(dian)(dian)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)、電(dian)(dian)(dian)(dian)力變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)、全密封(feng)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)、組合(he)式(shi)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)、干式(shi)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)、油(you)浸式(shi)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)、單相變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)、電(dian)(dian)(dian)(dian)爐變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)、整流(liu)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)等

5、低壓出線柜

6、補償柜

電(dian)(dian)(dian)力系統(tong)中的(de)(de)(de)負載類(lei)型大部(bu)分屬于感(gan)性負載，加(jia)上用電(dian)(dian)(dian)企業普遍廣泛地使(shi)用電(dian)(dian)(dian)力電(dian)(dian)(dian)子設(she)備，使(shi)電(dian)(dian)(dian)網功(gong)(gong)(gong)(gong)率(lv)因數較低(di)(di)。較低(di)(di)的(de)(de)(de)功(gong)(gong)(gong)(gong)率(lv)因數降低(di)(di)了(le)設(she)備利(li)用率(lv)，增加(jia)了(le)供(gong)電(dian)(dian)(dian)投資，損(sun)害了(le)電(dian)(dian)(dian)壓質量，降低(di)(di)了(le)設(she)備使(shi)用壽命，大大增加(jia)了(le)線路損(sun)耗。為(wei)了(le)改善電(dian)(dian)(dian)網功(gong)(gong)(gong)(gong)率(lv)因數低(di)(di)下帶來(lai)的(de)(de)(de)能源浪費和這些(xie)不利(li)供(gong)電(dian)(dian)(dian)生產的(de)(de)(de)因素，必(bi)須使(shi)電(dian)(dian)(dian)網功(gong)(gong)(gong)(gong)率(lv)因數得到有效的(de)(de)(de)提(ti)高。顯(xian)然這些(xie)無(wu)功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率(lv)如果都要由發電(dian)(dian)(dian)機提(ti)供(gong)并遠距離傳送是(shi)(shi)不合(he)理的(de)(de)(de)，通常也是(shi)(shi)不可能的(de)(de)(de)。合(he)理的(de)(de)(de)辦法就是(shi)(shi)在需要無(wu)功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率(lv)的(de)(de)(de)地方產生無(wu)功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率(lv)，即增加(jia)無(wu)功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率(lv)補償設(she)備與裝置
