一、高壓母線槽和低壓母線槽區別

通過字面的意思可以簡單地區別：低壓母線槽用(yong)于(yu)(yu)運行低壓(ya)電(dian)纜，高壓(ya)母(mu)線槽用(yong)于(yu)(yu)輸送高壓(ya)電(dian)纜。接下來小編就來介紹兩者(zhe)的材(cai)質和功能間的不同：

1、一(yi)般情(qing)況(kuang)下，1KV環(huan)境(jing)中使(shi)用的(de)都(dou)是(shi)低(di)電(dian)(dian)壓(ya)(ya)(ya)母(mu)(mu)(mu)線(xian)線(xian)路(lu)，在(zai)1kV以上的(de)電(dian)(dian)壓(ya)(ya)(ya)環(huan)境(jing)中，都(dou)是(shi)高(gao)(gao)(gao)壓(ya)(ya)(ya)母(mu)(mu)(mu)線(xian)線(xian)路(lu)，當然，也有根據現場(chang)環(huan)境(jing)來(lai)決(jue)定的(de)。如(ru)一(yi)般的(de)配電(dian)(dian)室都(dou)是(shi)低(di)壓(ya)(ya)(ya)母(mu)(mu)(mu)線(xian)路(lu)（注：能夠直接(jie)與電(dian)(dian)氣設備連接(jie)，均(jun)為低(di)壓(ya)(ya)(ya)環(huan)境(jing)，均(jun)為低(di)壓(ya)(ya)(ya)母(mu)(mu)(mu)線(xian)路(lu)）。在(zai)送(song)配電(dian)(dian)設備中，變壓(ya)(ya)(ya)器(qi)前的(de)高(gao)(gao)(gao)壓(ya)(ya)(ya)母(mu)(mu)(mu)線(xian)都(dou)是(shi)高(gao)(gao)(gao)壓(ya)(ya)(ya)母(mu)(mu)(mu)線(xian)，與外部高(gao)(gao)(gao)壓(ya)(ya)(ya)電(dian)(dian)線(xian)連接(jie)，在(zai)這些(xie)部位使(shi)用高(gao)(gao)(gao)壓(ya)(ya)(ya)母(mu)(mu)(mu)線(xian)線(xian)路(lu)。

2、低(di)(di)壓(ya)(ya)母(mu)(mu)線(xian)槽用于低(di)(di)壓(ya)(ya)環境，高壓(ya)(ya)母(mu)(mu)線(xian)槽用于高壓(ya)(ya)環境，低(di)(di)壓(ya)(ya)母(mu)(mu)線(xian)槽必須(xu)通(tong)過CCC認(ren)證，普通(tong)民眾無法獲得(de)高壓(ya)(ya)母(mu)(mu)線(xian)槽，不需要強(qiang)制性CCC認(ren)證。

3、高壓母線，是高壓電平的主線，一般采用高壓母線槽進行傳輸。高壓母線槽適用于大型變電(dian)(dian)站(zhan)和(he)大型企業，具有安全、美觀(guan)、可靠的(de)特點，因為高(gao)壓(ya)(ya)母線的(de)外(wai)殼是封閉的(de)，可以大大減少斷電(dian)(dian)和(he)大修次數，而由(you)于電(dian)(dian)流(liu)分布不平衡(heng)引起(qi)的(de)電(dian)(dian)流(liu)分配不平衡(heng)所引起(qi)的(de)故障，則可能是在輸送大電(dian)(dian)流(liu)時由(you)雙、三根高(gao)壓(ya)(ya)電(dian)(dian)纜引起(qi)的(de)。

這(zhe)里解釋下高低(di)壓母(mu)(mu)線、主(zhu)母(mu)(mu)線、硬母(mu)(mu)線、低(di)壓封閉母(mu)(mu)線槽(cao)與高強封閉母(mu)(mu)線槽(cao)的相關概念：

首(shou)先，電(dian)(dian)壓(ya)等級平(ping)分為高(gao)電(dian)(dian)壓(ya)和(he)低(di)電(dian)(dian)壓(ya)，一般的功耗為低(di)電(dian)(dian)壓(ya)。發(fa)電(dian)(dian)廠的功率(lv)被提升到客戶端(duan)進行傳輸，然后由變壓(ya)器降低(di)。變壓(ya)器原高(gao)壓(ya)接(jie)線為母線。

其次，具有高(gao)電壓等級的(de)(de)主線(xian)(xian)(xian)(xian)(xian)為母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)，母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)一(yi)般(ban)采用矩形或圓形截面裸導線(xian)(xian)(xian)(xian)(xian)或雙絞線(xian)(xian)(xian)(xian)(xian)，匯流條用于(yu)收集(ji)、分配和(he)傳(chuan)輸電能。該結構分為硬母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)和(he)軟母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)。硬母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)也分為矩形母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)和(he)管狀母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)。本(ben)發明的(de)(de)軟母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)結構簡單方便，成本(ben)低廉。對于(yu)室外，因為空(kong)間(jian)很大，所以線(xian)(xian)(xian)(xian)(xian)可以擺動，并且線(xian)(xian)(xian)(xian)(xian)路到線(xian)(xian)(xian)(xian)(xian)路的(de)(de)距(ju)離不夠。

二、低壓母線槽絕緣電阻要求

母線槽絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)(jian)產品的絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)值與母線槽(cao)(cao)(cao)的長度、周圍(wei)環境的濕度和溫度有(you)關，對(dui)低(di)(di)壓母線槽(cao)(cao)(cao)絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)(jian)進行絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)測量時，可采用500V絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)表，一般不(bu)(bu)能低(di)(di)于0.5M。國內母線槽(cao)(cao)(cao)絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)(jian)制(zhi)造廠對(dui)每(mei)單元(yuan)的母線槽(cao)(cao)(cao)絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)(jian)規定絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)不(bu)(bu)低(di)(di)于20M，通常(chang)能達到500M。每(mei)節母線槽(cao)(cao)(cao)絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)(jian)相與相及相與外殼之(zhi)間的絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)不(bu)(bu)低(di)(di)于20M，這是低(di)(di)要(yao)求，通常(chang)每(mei)節母線槽(cao)(cao)(cao)絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)值可達到500 M；每(mei)安(an)裝好(hao)一個單元(yuan)母線槽(cao)(cao)(cao)后應測量母線槽(cao)(cao)(cao)絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)(jian)的電(dian)(dian)阻(zu)，允(yun)許總絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)逐漸下降(jiang)，但不(bu)(bu)允(yun)許有(you)突變，且總絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)不(bu)(bu)應小于0.5 M 。
