配電柜內關鍵有(you)(you)：接線端子排、各種(zhong)各樣(yang)(yang)閘(zha)刀開(kai)關、保護機器(qi)設(she)備(bei)（空氣(qi)漏電(dian)(dian)(dian)開(kai)關、斷路(lu)器(qi)這類(lei)）、測(ce)量設(she)備(bei)（電(dian)(dian)(dian)流(liu)(liu)表、電(dian)(dian)(dian)流(liu)(liu)計、周波表等）計量檢(jian)定機器(qi)設(she)備(bei)（有(you)(you)功(gong)功(gong)率、無功(gong)負荷表）。底壓(ya)配電(dian)(dian)(dian)柜的類(lei)型許多 ，電(dian)(dian)(dian)子器(qi)件有(you)(you)非常大不一樣(yang)(yang)，以動力(li)柜為(wei)例子： 從上(shang)向下(xia)：刀閘(zha)、電(dian)(dian)(dian)壓(ya)互感(gan)器(qi)、空氣(qi)漏電(dian)(dian)(dian)開(kai)關、各環路(lu)空氣(qi)開(kai)關。假如立即操縱用電(dian)(dian)(dian)量，在環路(lu)空氣(qi)開(kai)關下(xia)也有(you)(you)交流(liu)(liu)接觸器(qi)、熱繼器(qi)、環路(lu)電(dian)(dian)(dian)壓(ya)互感(gan)器(qi)。自然(ran)也有(you)(you)電(dian)(dian)(dian)流(liu)(liu)計、電(dian)(dian)(dian)流(liu)(liu)表、工(gong)作(zuo)電(dian)(dian)(dian)壓(ya)切(qie)換開(kai)關、顯示燈。

高壓配電柜中的(de)電(dian)源防(fang)雷器(qi)(qi)一般全是選用浪(lang)涌保護(hu)(hu)器(qi)(qi)，當有雷擊電(dian)流量(liang)及短路(lu)故障(zhang)大電(dian)流量(liang)時，浪(lang)涌保護(hu)(hu)器(qi)(qi)內部(bu)的(de)接(jie)觸點合閉，一瞬間(jian)充放電(dian)，沒有雷擊電(dian)流量(liang)及路(lu)線短路(lu)容量(liang)時，內部(bu)接(jie)觸點斷(duan)掉(diao)，因而，浪(lang)涌保護(hu)(hu)器(qi)(qi)就可(ke)以做為電(dian)源防(fang)雷器(qi)(qi)，又可(ke)做為短路(lu)容量(liang)保護(hu)(hu)用。

配電箱是數(shu)據信息(xi)上(shang)的大量主要參(can)數(shu)，一般是組成底壓(ya)(ya)林(lin)按電(dian)氣設(she)備(bei)(bei)布線，規(gui)定將開關柜(ju)、檢(jian)測儀表、保護家(jia)用(yong)(yong)(yong)(yong)電(dian)器和輔助機(ji)器設(she)備(bei)(bei)拼(pin)裝在(zai)封閉式(shi)或(huo)封閉式(shi)金屬材(cai)料柜(ju)中(zhong)或(huo)屏幅(fu)上(shang)，組成底壓(ya)(ya)配電(dian)箱。一切正常運(yun)作時可依靠手動式(shi)或(huo)控制開關接入或(huo)開斷電(dian)源電(dian)路。高壓(ya)(ya)配電(dian)柜(ju)具備(bei)(bei)體型小、安裝簡單，技術性特(te)(te)性獨特(te)(te)、部位固定不動，配備(bei)(bei)作用(yong)(yong)(yong)(yong)與眾不同、不會受(shou)到場所限定，運(yun)用(yong)(yong)(yong)(yong)較為廣(guang)泛，實際(ji)操作平穩靠譜，空間利用(yong)(yong)(yong)(yong)率高，占地(di)面積少且具備(bei)(bei)環境保護效用(yong)(yong)(yong)(yong)的特(te)(te)性。
