武漢冷庫工程已安裝的電氣安裝工程可包括架空線路、照明、電纜、機房布線、車間或廠區的變配電。

1、架(jia)空線(xian)路(lu)送(song)電(dian)(dian)如(ru)果在長距離的情況下(xia)，經常使用室外架(jia)空電(dian)(dian)源。分為高壓和低壓兩種，都是由電(dian)(dian)桿(金(jin)屬塔(ta)、鋼筋混(hun)凝土或(huo)木(mu)桿)和電(dian)(dian)線(xian)組成(cheng)。1kv以下(xia)的低壓架(jia)空線(xian)，1kv以上的高壓架(jia)空線(xian)。

2、照(zhao)(zhao)(zhao)明(ming)(ming)(ming)電氣照(zhao)(zhao)(zhao)明(ming)(ming)(ming)根據冷庫的安(an)裝條件(jian)可(ke)(ke)分為一(yi)般照(zhao)(zhao)(zhao)明(ming)(ming)(ming)和(he)局(ju)部照(zhao)(zhao)(zhao)明(ming)(ming)(ming)。前者用(yong)(yong)于照(zhao)(zhao)(zhao)明(ming)(ming)(ming)整個區域(yu)，而后者僅用(yong)(yong)于照(zhao)(zhao)(zhao)明(ming)(ming)(ming)局(ju)部的某個工(gong)作場所。一(yi)般照(zhao)(zhao)(zhao)明(ming)(ming)(ming)和(he)局(ju)部照(zhao)(zhao)(zhao)明(ming)(ming)(ming)經常混合使用(yong)(yong)。特(te)殊車間(jian)或工(gong)作場所也(ye)有應急照(zhao)(zhao)(zhao)明(ming)(ming)(ming)。當普通(tong)照(zhao)(zhao)(zhao)明(ming)(ming)(ming)發生故(gu)障(zhang)并熄(xi)滅時(shi)，應急照(zhao)(zhao)(zhao)明(ming)(ming)(ming)可(ke)(ke)確保冷庫安(an)裝人員撤離或不中斷他們的工(gong)作。如果車間(jian)內(nei)有爆炸危險，應配備(bei)應急照(zhao)(zhao)(zhao)明(ming)(ming)(ming)。

3、電(dian)纜的一根(gen)或幾根(gen)導線的線芯包(bao)好相應(ying)的絕緣(yuan)層(ceng)后，再包(bao)一層(ceng)密封護套(鋁、鉛或塑料(liao)等(deng)。).這種(zhong)電(dian)線叫做電(dian)纜。在冷庫安裝工程中，電(dian)纜一般分為動(dong)力電(dian)纜和控(kong)制(zhi)電(dian)纜。電(dian)纜用(yong)于(yu)傳輸和分配高(gao)功率電(dian)能(neng)。控(kong)制(zhi)電(dian)纜用(yong)于(yu)連接冰箱和其他設(she)備的控(kong)制(zhi)線。電(dian)纜架空敷設(she)、埋地敷設(she)和地溝(gou)敷設(she)。

4、機房(fang)布(bu)線(xian)(xian)(xian)機房(fang)布(bu)線(xian)(xian)(xian)是從配(pei)電(dian)箱(xiang)(或(huo)控制箱(xiang))到電(dian)機的(de)供電(dian)和控制線(xian)(xian)(xian)路，有(you)明配(pei)和暗配(pei)兩(liang)種(zhong)布(bu)線(xian)(xian)(xian)。電(dian)線(xian)(xian)(xian)沿墻壁、天花(hua)(hua)板(ban)、梁(liang)、柱等以開(kai)放的(de)方(fang)式(shi)敷(fu)設，稱(cheng)為(wei)開(kai)放式(shi)分布(bu)。埋在(zai)墻壁、地板(ban)或(huo)天花(hua)(hua)板(ban)中的(de)電(dian)線(xian)(xian)(xian)稱(cheng)為(wei)暗配(pei)。按(an)布(bu)線(xian)(xian)(xian)方(fang)式(shi)分，通常有(you)瓷(塑(su))膠合(he)板(ban)布(bu)線(xian)(xian)(xian)、瓷瓶(ping)布(bu)線(xian)(xian)(xian)、槽板(ban)布(bu)線(xian)(xian)(xian)、鋼管或(huo)塑(su)料管布(bu)線(xian)(xian)(xian)、鋁卡布(bu)線(xian)(xian)(xian)和鋼索布(bu)線(xian)(xian)(xian)等。對布(bu)線(xian)(xian)(xian)的(de)基本要(yao)求是：不(bu)僅要(yao)有(you)可靠(kao)的(de)電(dian)力傳輸(shu)，還要(yao)有(you)合(he)理整潔(jie)的(de)安(an)裝(zhuang)布(bu)局和牢固的(de)安(an)裝(zhuang)冷庫工程。

5、變壓(ya)器(qi)(qi)和配(pei)電設備(bei)。變配(pei)電設備(bei)是(shi)用(yong)于(yu)轉換電源和分配(pei)電能的電氣(qi)裝(zhuang)(zhuang)置(zhi)。它(ta)由變壓(ya)器(qi)(qi)、開關設備(bei)、保護(hu)裝(zhuang)(zhuang)置(zhi)、測量儀器(qi)(qi)、連接母線和電纜組成。有兩種配(pei)電方式：室(shi)內(nei)和室(shi)外(wai)。室(shi)內(nei)電壓(ya)較(jiao)低，一般在35kV以下，室(shi)外(wai)電壓(ya)一般在35kV以上。但一些(xie)6-10kV電壓(ya)的小功率終端配(pei)電設備(bei)往往安裝(zhuang)(zhuang)在室(shi)外(wai)。通用(yong)冷庫工程變配(pei)電設備(bei)多在室(shi)內(nei)。
