在我們的(de)生(sheng)活中，低壓(ya)開(kai)(kai)關(guan)柜可(ke)能并不是(shi)被大眾(zhong)所知，但它跟我們的(de)生(sheng)活用(yong)電(dian)緊緊相(xiang)連。低壓(ya)開(kai)(kai)關(guan)柜用(yong)于發電(dian)廠、石油化(hua)工、治金紡織、高層(ceng)建筑等行業，其作(zuo)用(yong)就是(shi)用(yong)于輸(shu)電(dian)、配電(dian)及電(dian)能轉換(huan)。產品(pin)是(shi)根據GB7251.1-2013《低壓(ya)成套開(kai)(kai)關(guan)設備(bei)》(IDT IEC60439-1 1999)標(biao)準規定來生(sheng)產制造(zao)的(de)。那(nei)么，我們在使用(yong)低壓(ya)開(kai)(kai)關(guan)柜安(an)裝使用(yong)時，配線需要注意(yi)那(nei)些問題?

1、配線(xian)(xian)(xian)時低壓開關(guan)柜不(bu)(bu)得(de)緊貼金(jin)屬板(ban)敷設，線(xian)(xian)(xian)束(shu)(shu)穿(chuan)過(guo)鋼板(ban)孔(kong)時采取防護(hu)措施(shi)。每個端子(zi)接線(xian)(xian)(xian)不(bu)(bu)得(de)超過(guo)兩根。采用線(xian)(xian)(xian)束(shu)(shu)布(bu)線(xian)(xian)(xian)時，固(gu)(gu)定(ding)(ding)線(xian)(xian)(xian)束(shu)(shu)應橫平豎(shu)直布(bu)置，并(bing)應捆(kun)扎和(he)固(gu)(gu)定(ding)(ding)。捆(kun)扎間(jian)(jian)距不(bu)(bu)宜大于(yu)100mm，水平線(xian)(xian)(xian)束(shu)(shu)固(gu)(gu)定(ding)(ding)間(jian)(jian)距不(bu)(bu)宜大于(yu)300mm，垂(chui)直線(xian)(xian)(xian)束(shu)(shu)固(gu)(gu)定(ding)(ding)間(jian)(jian)距不(bu)(bu)宜大于(yu)400mm。

2、低壓開關柜線(xian)(xian)(xian)束穿越金屬孔或在過(guo)門處、轉角處，應在線(xian)(xian)(xian)束穿越部(bu)分纏(chan)上膠(jiao)帶(dai)(dai)。過(guo)門處膠(jiao)帶(dai)(dai)要求纏(chan)2~3層(ceng)，長度約60mm，其他位(wei)置則視(shi)情況而定，應保證孔的(de)兩側膠(jiao)帶(dai)(dai)各留有20mm以上的(de)裕量。當懸掛線(xian)(xian)(xian)束未固(gu)定長度超過(guo)300mm時，應固(gu)定導線(xian)(xian)(xian)。線(xian)(xian)(xian)束與帶(dai)(dai)電(dian)母線(xian)(xian)(xian)，電(dian)器出線(xian)(xian)(xian)端(duan)或帶(dai)(dai)電(dian)裸(luo)線(xian)(xian)(xian)間有大于表1規(gui)定的(de)距離(li)。

3、低(di)壓開關柜(ju)檢(jian)查電氣(qi)連接(jie)(jie)(jie)(jie)部(bu)分(fen)應(ying)連接(jie)(jie)(jie)(jie)牢固，接(jie)(jie)(jie)(jie)觸良好(hao)，無松動現(xian)象。按二(er)次(ci)接(jie)(jie)(jie)(jie)線(xian)(xian)圖進行施工，接(jie)(jie)(jie)(jie)線(xian)(xian)正(zheng)確。配線(xian)(xian)整齊(qi)、美觀(guan)、導線(xian)(xian)絕緣應(ying)良好(hao)、無損傷。每(mei)個接(jie)(jie)(jie)(jie)線(xian)(xian)端(duan)子應(ying)只接(jie)(jie)(jie)(jie)一根(gen)導線(xian)(xian)，很多不超過兩根(gen)(只有當(dang)該端(duan)子或接(jie)(jie)(jie)(jie)線(xian)(xian)柱是為接(jie)(jie)(jie)(jie)兩根(gen)導線(xian)(xian)而專門設(she)計的(de)才允許接(jie)(jie)(jie)(jie)兩根(gen)導線(xian)(xian))。
