配電箱安裝

1、如果管道(dao)隱蔽，接(jie)線應(ying)穿過配(pei)電箱背面的孔。如果管道(dao)外露，防火(huo)電纜橋架，布線應(ying)穿過底部的孔。

2、箱體與鋼(gang)管(guan)(guan)之間采用塑料銅線和跨接(jie)地線。鋼(gang)管(guan)(guan)采用焊接(jie)鋼(gang)管(guan)(guan)時，應在(zai)(zai)(zai)鋼(gang)管(guan)(guan)上焊接(jie)接(jie)地螺栓作為鋼(gang)管(guan)(guan)的跨接(jie)地，導(dao)線兩端的線鼻子(zi)應用螺栓壓接(jie)。鍍(du)鋅鋼(gang)管(guan)(guan)采用卡箍連接(jie)。在(zai)(zai)(zai)配(pei)電箱中，接(jie)地線壓接(jie)在(zai)(zai)(zai)PE總線端子(zi)上。不要從接(jie)線盒接(jie)地保(bao)護(hu)端子(zi)串聯(lian)。

3、配電箱應有明(ming)(ming)顯(xian)可(ke)靠的接地。帶(dai)器具的鐵(tie)板(ban)、帶(dai)器具的門(men)應設置明(ming)(ming)顯(xian)可(ke)靠的裸銅編織線(xian)作為接地保護線(xian)。配電箱中的PE線(xian)不得串接。

4、與配(pei)電(dian)箱連(lian)接(jie)的(de)明配(pei)管(guan)應采用管(guan)卡固定，距(ju)地200mm處(chu)應有一(yi)固，距(ju)進線箱200mm處(chu)應有一(yi)固，鍍鋅電(dian)纜(lan)橋架，管(guan)卡應與管(guan)徑相匹(pi)配(pei)。

5、配電(dian)箱上(shang)的電(dian)動工(gong)具、儀表應(ying)牢(lao)固、平整(zheng)、整(zheng)齊，間距(ju)均勻，鋼接線端子(zi)無松動，開關靈活，電(dian)纜橋(qiao)架，零件齊全。

6、配電箱安裝應(ying)牢(lao)固、平整，其垂(chui)直度(du)允許偏差為3mm。

7、電氣豎(shu)井金屬線(xian)槽(cao)及配電箱安裝 。

同一(yi)型號不同規格電(dian)纜橋架的重(zhong)量是不同的

例如槽(cao)(cao)式(shi)200*100規格橋架(jia)(jia)(jia)要(yao)比(bi)300*100規格橋架(jia)(jia)(jia)的(de)重(zhong)量(liang)輕，因為(wei)槽(cao)(cao)式(shi)200*100電(dian)(dian)纜(lan)橋架(jia)(jia)(jia)托(tuo)盤展開(kai)寬度(du)(du)為(wei)420mm，重(zhong)量(liang)約為(wei)3.63公斤，槽(cao)(cao)式(shi)300*100電(dian)(dian)纜(lan)橋架(jia)(jia)(jia)托(tuo)盤展開(kai)寬度(du)(du)為(wei)520mm，重(zhong)量(liang)約為(wei)4.49公斤，從(cong)上(shang)面可(ke)以(yi)看出300*100槽(cao)(cao)式(shi)電(dian)(dian)纜(lan)橋架(jia)(jia)(jia)比(bi)200*100槽(cao)(cao)式(shi)電(dian)(dian)纜(lan)橋架(jia)(jia)(jia)的(de)重(zhong)量(liang)要(yao)多0.8公斤。注：以(yi)上(shang)重(zhong)量(liang)均為(wei)一米的(de)重(zhong)量(liang)。

例如梯式(shi)200*100規(gui)(gui)格(ge)(ge)橋(qiao)架(jia)(jia)要比200*50規(gui)(gui)格(ge)(ge)橋(qiao)架(jia)(jia)的(de)(de)重(zhong)量(liang)(liang)重(zhong)，因為梯式(shi)200*100電(dian)(dian)纜(lan)橋(qiao)架(jia)(jia)側(ce)板(ban)的(de)(de)高度100mm，側(ce)板(ban)合計(ji)重(zhong)量(liang)(liang)為2.25公(gong)(gong)斤，梯式(shi)200*50電(dian)(dian)纜(lan)橋(qiao)架(jia)(jia)側(ce)板(ban)的(de)(de)高度為50mm，側(ce)板(ban)重(zhong)量(liang)(liang)合計(ji)為1.38公(gong)(gong)斤。橋(qiao)架(jia)(jia)規(gui)(gui)格(ge)(ge)為200*100和200*50梯式(shi)電(dian)(dian)纜(lan)橋(qiao)架(jia)(jia)所(suo)有橫撐的(de)(de)數(shu)量(liang)(liang)和規(gui)(gui)格(ge)(ge)是相同(tong)的(de)(de)，所(suo)以(yi)這(zhe)兩個規(gui)(gui)格(ge)(ge)橫撐的(de)(de)重(zhong)量(liang)(liang)是相同(tong)的(de)(de)，所(suo)以(yi)200*100梯式(shi)電(dian)(dian)纜(lan)橋(qiao)架(jia)(jia)要比200*50梯式(shi)電(dian)(dian)纜(lan)橋(qiao)架(jia)(jia)的(de)(de)重(zhong)量(liang)(liang)要多(duo)0.8公(gong)(gong)斤左右。注：以(yi)上重(zhong)量(liang)(liang)均為一米(mi)的(de)(de)重(zhong)量(liang)(liang)。
