2、高壓計量柜

一般都裝設專用的高壓電能計量柜，供電能計量用，即(ji)所謂的高供高計方式

3、變壓器

變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)（Transformer）是利用(yong)電(dian)(dian)磁(ci)感應的(de)原理(li)來改變(bian)(bian)(bian)(bian)交流電(dian)(dian)壓(ya)(ya)(ya)(ya)的(de)裝置，主(zhu)要構件(jian)是初級(ji)線圈(quan)、次級(ji)線圈(quan)和鐵心(xin)（磁(ci)芯）。在(zai)電(dian)(dian)器(qi)(qi)(qi)(qi)設(she)備和無線電(dian)(dian)路中，常用(yong)作升降電(dian)(dian)壓(ya)(ya)(ya)(ya)、匹配阻抗，安全隔離(li)等。主(zhu)要功能有(you)：電(dian)(dian)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)換(huan)、電(dian)(dian)流變(bian)(bian)(bian)(bian)換(huan)、阻抗變(bian)(bian)(bian)(bian)換(huan)、隔離(li)、穩壓(ya)(ya)(ya)(ya)（磁(ci)飽(bao)和變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)）等。按用(yong)途可以(yi)分為：配電(dian)(dian)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、電(dian)(dian)力變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、全密封變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、組合(he)式(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、干式(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、油浸式(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、單(dan)相(xiang)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、電(dian)(dian)爐變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)、整流變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)等

4、低壓進線柜

5、低壓出線柜

6、補償柜

電(dian)(dian)(dian)(dian)力系統中(zhong)的(de)負載類(lei)型大(da)部分屬于感性負載，加上用電(dian)(dian)(dian)(dian)企業普(pu)遍廣(guang)泛地(di)使(shi)(shi)用電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)子設備，使(shi)(shi)電(dian)(dian)(dian)(dian)網(wang)(wang)功(gong)(gong)(gong)率(lv)(lv)(lv)因數(shu)較(jiao)低(di)。較(jiao)低(di)的(de)功(gong)(gong)(gong)率(lv)(lv)(lv)因數(shu)降低(di)了(le)設備利(li)用率(lv)(lv)(lv)，增加了(le)供電(dian)(dian)(dian)(dian)投資，損(sun)害了(le)電(dian)(dian)(dian)(dian)壓質量(liang)，降低(di)了(le)設備使(shi)(shi)用壽(shou)命，大(da)大(da)增加了(le)線路(lu)損(sun)耗。為了(le)改善電(dian)(dian)(dian)(dian)網(wang)(wang)功(gong)(gong)(gong)率(lv)(lv)(lv)因數(shu)低(di)下帶來的(de)能源浪(lang)費和這些不(bu)(bu)(bu)利(li)供電(dian)(dian)(dian)(dian)生產的(de)因素，必須使(shi)(shi)電(dian)(dian)(dian)(dian)網(wang)(wang)功(gong)(gong)(gong)率(lv)(lv)(lv)因數(shu)得到有效的(de)提高(gao)。顯然這些無功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)如果都要由發電(dian)(dian)(dian)(dian)機提供并(bing)遠距離傳送是(shi)(shi)不(bu)(bu)(bu)合(he)理的(de)，通(tong)常也是(shi)(shi)不(bu)(bu)(bu)可能的(de)。合(he)理的(de)辦法就是(shi)(shi)在需(xu)要無功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)的(de)地(di)方產生無功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)，即增加無功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)補償設備與(yu)裝置
