戶外大連配電箱主(zhu)要用作對于(yu)用電(dian)(dian)設備的控制、配(pei)(pei)電(dian)(dian)，對于(yu)線(xian)路的過載、短(duan)路、漏電(dian)(dian)起到(dao)保(bao)護(hu)作用。戶外配(pei)(pei)電(dian)(dian)箱在各種場所都(dou)有安(an)裝(zhuang)，學校、機關、醫院、工廠(chang)、車(che)間甚至家(jia)庭都(dou)能發現(xian)配(pei)(pei)電(dian)(dian)箱。

大連配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)(箱(xiang)(xiang)(xiang))分動力配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)(箱(xiang)(xiang)(xiang))和照明配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)(箱(xiang)(xiang)(xiang))、計(ji)量柜(ju)(ju)(ju)(箱(xiang)(xiang)(xiang))，是(shi)配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)系(xi)統(tong)(tong)的末級設備。配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)是(shi)電(dian)(dian)(dian)(dian)動機(ji)控制中(zhong)心的統(tong)(tong)稱(cheng)。配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)使用(yong)在負(fu)荷比較(jiao)分散、回路(lu)較(jiao)少的場(chang)合;電(dian)(dian)(dian)(dian)動機(ji)控制中(zhong)心用(yong)于(yu)負(fu)荷集(ji)中(zhong)、回路(lu)較(jiao)多的場(chang)合。它(ta)們把上一級配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)設備某一電(dian)(dian)(dian)(dian)路(lu)的電(dian)(dian)(dian)(dian)能分配(pei)(pei)(pei)(pei)給就近(jin)的負(fu)荷。戶外(wai)配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)作為(wei)電(dian)(dian)(dian)(dian)力系(xi)統(tong)(tong)中(zhong)所(suo)有開關設備、測量儀(yi)表、保護電(dian)(dian)(dian)(dian)器和輔助設備組裝高(gao)低壓的配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)裝置，它(ta)可以合理的分配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)能、電(dian)(dian)(dian)(dian)路(lu)的開合操作、顯示電(dian)(dian)(dian)(dian)力運行中(zhong)的各種參(can)數、報警等(deng)作用(yong)。

最(zui)早用(yong)于變壓器(qi)鐵(tie)(tie)芯(xin)的(de)(de)(de)材料是易(yi)于磁(ci)化和退磁(ci)的(de)(de)(de)軟熟(shu)鐵(tie)(tie)，為了克服磁(ci)回(hui)路中由(you)(you)周(zhou)期性(xing)磁(ci)化所產生的(de)(de)(de)磁(ci)阻損(sun)失和鐵(tie)(tie)芯(xin)由(you)(you)于受交(jiao)變磁(ci)通切割(ge)而(er)(er)產生的(de)(de)(de)渦(wo)流，變壓器(qi)鐵(tie)(tie)芯(xin)是由(you)(you)鐵(tie)(tie)線束制成，而(er)(er)不是由(you)(you)整塊鐵(tie)(tie)構成。戶(hu)外配電箱的(de)(de)(de)鋼(gang)板一定要厚，機柜內部的(de)(de)(de)支架要粗大，因為可以承受更重的(de)(de)(de)壓力。大連(lian)配電箱的(de)(de)(de)所有(you)鋼(gang)材都需要噴(pen)漆，而(er)(er)且噴(pen)漆一定要均勻，這(zhe)樣才(cai)能更好(hao)的(de)(de)(de)防銹防塵。

因為(wei)高低壓開關柜體積都比(bi)較大(da)，所以(yi)在安(an)裝(zhuang)的(de)時(shi)候盡量不要私自安(an)裝(zhuang)，而是借助于專業人員(yuan)的(de)幫助，這樣才可以(yi)使(shi)得高低壓開關柜安(an)全的(de)安(an)裝(zhuang)和放心的(de)使(shi)用。
