1.分支箱配電柜廠家向用戶推薦自己生產的也許并不適合用戶的產品。2.成都分支箱設(she)計院對某些新推出的柜型并不(bu)(bu)太了解只(zhi)是根(gen)據用戶要求進行設(she)計。3.用戶對自己的需(xu)求并不(bu)(bu)十分了解,選擇柜型時不(bu)(bu)能(neng)根(gen)據自己所需(xu)進行選擇。

改進(jin)(jin)原配(pei)電(dian)箱(xiang)的低壓電(dian)容(rong)器(qi)(qi)組的接(jie)線方式，將(jiang)其安裝位置由交流(liu)接(jie)觸器(qi)(qi)上樁頭(tou)，改成接(jie)在配(pei)電(dian)箱(xiang)低壓進(jin)(jin)線與計(ji)量表計(ji)之間。防止(zhi)因運行(xing)中電(dian)容(rong)器(qi)(qi)電(dian)路發生缺相故障或電(dian)容(rong)器(qi)(qi)損壞時，造成計(ji)量裝置計(ji)量不準(zhun)確。此外，電(dian)容(rong)器(qi)(qi)選擇型(xing)號應為BSMJ系列產(chan)品，以保證元件質量可靠、安全運行(xing)。

1.主(zhu)母線最(zui)大(da)額(e)定(ding)電(dian)(dian)(dian)(dian)流:主(zhu)母線最(zui)大(da)能夠承(cheng)載(zai)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)額(e)定(ding)值。2.額(e)定(ding)短(duan)時(shi)耐(nai)受電(dian)(dian)(dian)(dian)流:由生產廠家(jia)給出的(de)(de)(de)(de),成套設(she)備中(zhong)某條(tiao)電(dian)(dian)(dian)(dian)路(lu)在國(guo)家(jia)標準(zhun)GB7251.1-2005中(zhong)8.2.3規定(ding)的(de)(de)(de)(de)試(shi)驗條(tiao)件(jian)下能安(an)全(quan)承(cheng)載(zai)的(de)(de)(de)(de)短(duan)時(shi)耐(nai)受電(dian)(dian)(dian)(dian)流方均根值。3.峰值短(duan)時(shi)耐(nai)受電(dian)(dian)(dian)(dian)流:在規定(ding)試(shi)驗條(tiao)件(jian)下,生產廠家(jia)規定(ding)此(ci)電(dian)(dian)(dian)(dian)路(lu)能夠圓(yuan)滿地(di)承(cheng)受的(de)(de)(de)(de)峰值電(dian)(dian)(dian)(dian)流。4.外(wai)殼防(fang)護(hu)等(deng)(deng)級(ji):IEC60529-1989標準(zhun)由成套設(she)備提供的(de)(de)(de)(de)防(fang)止觸及帶電(dian)(dian)(dian)(dian)部件(jian),以及外(wai)來(lai)固(gu)體的(de)(de)(de)(de)侵入(ru)和液體的(de)(de)(de)(de)進入(ru)的(de)(de)(de)(de)等(deng)(deng)級(ji)。具體等(deng)(deng)級(ji)劃分詳見(jian)IEC60529標準(zhun)。5.內部分隔方式:根據IEC60529-1989標準(zhun),為保護(hu)人身安(an)全(quan),將開關柜(ju)獨立劃分成幾個隔室的(de)(de)(de)(de)不同方式。不同型(xing)號的(de)(de)(de)(de)配(pei)(pei)(pei)電(dian)(dian)(dian)(dian)柜(ju)之間的(de)(de)(de)(de)技(ji)術(shu)參(can)數(shu)都有很大(da)不同,而(er)進口(kou)配(pei)(pei)(pei)電(dian)(dian)(dian)(dian)柜(ju)的(de)(de)(de)(de)技(ji)術(shu)參(can)數(shu)基本都優(you)于國(guo)產配(pei)(pei)(pei)電(dian)(dian)(dian)(dian)柜(ju),但(dan)并不能認為進口(kou)配(pei)(pei)(pei)電(dian)(dian)(dian)(dian)柜(ju)就一定(ding)比國(guo)產配(pei)(pei)(pei)電(dian)(dian)(dian)(dian)柜(ju)好(hao)。

暗裝配(pei)電(dian)箱(xiang)，配(pei)電(dian)箱(xiang)嵌入墻內(nei)安裝，在砌墻時預留孔洞應比配(pei)電(dian)箱(xiang)的長和寬各大20mm左(zuo)右，預留的深度(du)為配(pei)電(dian)箱(xiang)厚度(du)加上洞內(nei)壁(bi)抹灰(hui)的厚度(du)。在圬埋配(pei)電(dian)箱(xiang)時，箱(xiang)體與墻之間填(tian)以混凝土即可把箱(xiang)體固定(ding)住。
