2、高壓計量柜

一般都裝設專用的(de)高壓電能計量柜，供電能計量用，即所謂的(de)高供高計方式

3、變壓器

變(bian)(bian)壓(ya)(ya)器(qi)（Transformer）是利用(yong)(yong)電(dian)(dian)磁(ci)感(gan)應的原理來改變(bian)(bian)交流電(dian)(dian)壓(ya)(ya)的裝置，主要構件是初級線(xian)圈(quan)、次(ci)級線(xian)圈(quan)和鐵心(xin)（磁(ci)芯）。在電(dian)(dian)器(qi)設備和無線(xian)電(dian)(dian)路(lu)中，常用(yong)(yong)作(zuo)升(sheng)降電(dian)(dian)壓(ya)(ya)、匹配阻抗(kang)，安全隔離(li)等(deng)。主要功能有：電(dian)(dian)壓(ya)(ya)變(bian)(bian)換、電(dian)(dian)流變(bian)(bian)換、阻抗(kang)變(bian)(bian)換、隔離(li)、穩壓(ya)(ya)（磁(ci)飽(bao)和變(bian)(bian)壓(ya)(ya)器(qi)）等(deng)。按用(yong)(yong)途可(ke)以分為(wei)：配電(dian)(dian)變(bian)(bian)壓(ya)(ya)器(qi)、電(dian)(dian)力(li)變(bian)(bian)壓(ya)(ya)器(qi)、全密封變(bian)(bian)壓(ya)(ya)器(qi)、組合(he)式變(bian)(bian)壓(ya)(ya)器(qi)、干式變(bian)(bian)壓(ya)(ya)器(qi)、油(you)浸式變(bian)(bian)壓(ya)(ya)器(qi)、單(dan)相(xiang)變(bian)(bian)壓(ya)(ya)器(qi)、電(dian)(dian)爐變(bian)(bian)壓(ya)(ya)器(qi)、整流變(bian)(bian)壓(ya)(ya)器(qi)等(deng)

4、低壓進線柜

5、低壓出線柜

6、補償柜

電(dian)(dian)力(li)系統中的(de)(de)負載(zai)類(lei)型(xing)大(da)(da)部分屬于感性負載(zai)，加上用電(dian)(dian)企業普遍廣泛地(di)使用電(dian)(dian)力(li)電(dian)(dian)子設(she)備(bei)，使電(dian)(dian)網(wang)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)因(yin)(yin)數較低。較低的(de)(de)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)因(yin)(yin)數降低了(le)(le)(le)設(she)備(bei)利用率(lv)(lv)，增(zeng)(zeng)加了(le)(le)(le)供(gong)電(dian)(dian)投資，損害了(le)(le)(le)電(dian)(dian)壓質量，降低了(le)(le)(le)設(she)備(bei)使用壽命(ming)，大(da)(da)大(da)(da)增(zeng)(zeng)加了(le)(le)(le)線路損耗。為了(le)(le)(le)改善電(dian)(dian)網(wang)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)因(yin)(yin)數低下帶來的(de)(de)能源(yuan)浪(lang)費和這些(xie)不利供(gong)電(dian)(dian)生產(chan)的(de)(de)因(yin)(yin)素，必須使電(dian)(dian)網(wang)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)因(yin)(yin)數得到有效的(de)(de)提高。顯然這些(xie)無功(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)如果都(dou)要由發電(dian)(dian)機(ji)提供(gong)并遠距離傳送是(shi)(shi)不合理(li)的(de)(de)，通常也是(shi)(shi)不可(ke)能的(de)(de)。合理(li)的(de)(de)辦法就是(shi)(shi)在需(xu)要無功(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)的(de)(de)地(di)方產(chan)生無功(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)，即增(zeng)(zeng)加無功(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)補償(chang)設(she)備(bei)與裝(zhuang)置(zhi)
