車間變電所內裝有大連高低壓開關柜變(bian)壓(ya)器(qi)，將(jiang)6-10kV的高壓(ya)電(dian)(dian)(dian)降為(wei)一般(ban)低壓(ya)用(yong)電(dian)(dian)(dian)設(she)備所需的電(dian)(dian)(dian)壓(ya)，然(ran)后由低壓(ya)配電(dian)(dian)(dian)線路將(jiang)電(dian)(dian)(dian)能分送給各(ge)用(yong)電(dian)(dian)(dian)設(she)備使(shi)用(yong)。

    工(gong)廠里面也是需要用電(dian)的(de)(de)(de)，如果(guo)要用電(dian)的(de)(de)(de)話，那么(me)肯定(ding)會安裝大連高低壓開關柜(ju)(ju)，所以大家(jia)對于工(gong)廠配(pei)電(dian)柜(ju)(ju)的(de)(de)(de)尺寸也是要去進行了解的(de)(de)(de)，一般(ban)工(gong)廠配(pei)電(dian)柜(ju)(ju)比較(jiao)常(chang)見的(de)(de)(de)尺寸有230mm*240mm*9mm、280mm*280mm*9mm、如果(guo)大家(jia)要去選擇配(pei)電(dian)柜(ju)(ju)的(de)(de)(de)話，要根據自(zi)己的(de)(de)(de)需要去選擇合適(shi)的(de)(de)(de)尺寸。 

    大連高低壓(ya)開關柜配(pei)(pei)電(dian)系統(tong)(tong)一般由 電(dian)力變壓(ya)器、配(pei)(pei)電(dian)裝(zhuang)(zhuang)置(zhi)(zhi)、保(bao)(bao)護(hu)裝(zhuang)(zhuang)置(zhi)(zhi)、操作(zuo)機構、自動裝(zhuang)(zhuang)置(zhi)(zhi)、測量儀表(biao)及附屬設備構成(cheng)。供(gong)配(pei)(pei)電(dian)系統(tong)(tong)中的保(bao)(bao)護(hu)裝(zhuang)(zhuang)置(zhi)(zhi)也屬于配(pei)(pei)電(dian)裝(zhuang)(zhuang)置(zhi)(zhi)，按(an)其工作(zuo)電(dian)壓(ya)的不同又可分為高壓(ya)配(pei)(pei)電(dian)裝(zhuang)(zhuang)置(zhi)(zhi)和低壓(ya)配(pei)(pei)電(dian)裝(zhuang)(zhuang)置(zhi)(zhi)。

    電(dian)(dian)(dian)力(li)變(bian)壓(ya)(ya)器在供配電(dian)(dian)(dian)系統(tong)中的作(zuo)用是將(jiang)一(yi)種電(dian)(dian)(dian)壓(ya)(ya)的電(dian)(dian)(dian)能(neng)(neng)轉(zhuan)(zhuan)變(bian)為另(ling)一(yi)種或幾(ji)種電(dian)(dian)(dian)壓(ya)(ya)的電(dian)(dian)(dian)能(neng)(neng)供給(gei)用戶(hu)。變(bian)電(dian)(dian)(dian)所或配電(dian)(dian)(dian)房中的電(dian)(dian)(dian)力(li)變(bian)壓(ya)(ya)器，通(tong)常是將(jiang)高壓(ya)(ya)電(dian)(dian)(dian)能(neng)(neng)轉(zhuan)(zhuan)變(bian)為低(di)壓(ya)(ya)電(dian)(dian)(dian)能(neng)(neng)，饋電(dian)(dian)(dian)給(gei)用電(dian)(dian)(dian)設備(bei)。
