2、高壓計量柜

一般都(dou)裝(zhuang)設專(zhuan)用(yong)的(de)高壓電(dian)能(neng)計(ji)(ji)量柜，供(gong)電(dian)能(neng)計(ji)(ji)量用(yong)，即所謂的(de)高供(gong)高計(ji)(ji)方式

3、變壓器

變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)（Transformer）是利用(yong)電(dian)(dian)磁(ci)感應的原理來改(gai)變(bian)(bian)(bian)(bian)(bian)交流(liu)電(dian)(dian)壓(ya)(ya)(ya)(ya)的裝置，主(zhu)要(yao)構件是初級線圈(quan)、次級線圈(quan)和鐵心（磁(ci)芯(xin)）。在電(dian)(dian)器(qi)(qi)(qi)設備和無(wu)線電(dian)(dian)路(lu)中，常用(yong)作升降電(dian)(dian)壓(ya)(ya)(ya)(ya)、匹配(pei)阻抗，安全隔離(li)等。主(zhu)要(yao)功(gong)能有：電(dian)(dian)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)(bian)換(huan)、電(dian)(dian)流(liu)變(bian)(bian)(bian)(bian)(bian)換(huan)、阻抗變(bian)(bian)(bian)(bian)(bian)換(huan)、隔離(li)、穩壓(ya)(ya)(ya)(ya)（磁(ci)飽和變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)）等。按用(yong)途可以分為：配(pei)電(dian)(dian)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、電(dian)(dian)力變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、全密封變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、組合(he)式變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、干式變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、油(you)浸式變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、單相變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、電(dian)(dian)爐變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、整流(liu)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)等

5、低壓出線柜

6、補償柜

電力系統中的(de)(de)(de)負載(zai)類型大(da)(da)部(bu)分屬于感性負載(zai)，加(jia)上用電企業普遍廣泛地使用電力電子設(she)備(bei)，使電網(wang)功(gong)率(lv)(lv)(lv)(lv)(lv)因(yin)(yin)數(shu)較低。較低的(de)(de)(de)功(gong)率(lv)(lv)(lv)(lv)(lv)因(yin)(yin)數(shu)降(jiang)低了(le)設(she)備(bei)利(li)用率(lv)(lv)(lv)(lv)(lv)，增(zeng)加(jia)了(le)供電投資，損(sun)害了(le)電壓質量(liang)，降(jiang)低了(le)設(she)備(bei)使用壽命，大(da)(da)大(da)(da)增(zeng)加(jia)了(le)線路損(sun)耗(hao)。為了(le)改善電網(wang)功(gong)率(lv)(lv)(lv)(lv)(lv)因(yin)(yin)數(shu)低下帶來的(de)(de)(de)能源浪費和這些(xie)不(bu)(bu)利(li)供電生產的(de)(de)(de)因(yin)(yin)素，必須(xu)使電網(wang)功(gong)率(lv)(lv)(lv)(lv)(lv)因(yin)(yin)數(shu)得到有效的(de)(de)(de)提高。顯(xian)然這些(xie)無功(gong)功(gong)率(lv)(lv)(lv)(lv)(lv)如(ru)果(guo)都要由(you)發電機提供并(bing)遠距離傳(chuan)送是不(bu)(bu)合理(li)(li)的(de)(de)(de)，通常也是不(bu)(bu)可(ke)能的(de)(de)(de)。合理(li)(li)的(de)(de)(de)辦法就是在(zai)需要無功(gong)功(gong)率(lv)(lv)(lv)(lv)(lv)的(de)(de)(de)地方產生無功(gong)功(gong)率(lv)(lv)(lv)(lv)(lv)，即增(zeng)加(jia)無功(gong)功(gong)率(lv)(lv)(lv)(lv)(lv)補償(chang)設(she)備(bei)與裝置
