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：低壓母線槽用于運行低壓電(dian)(dian)纜(lan)，高(gao)(gao)壓母線槽用于輸送(song)高(gao)(gao)壓電(dian)(dian)纜(lan)。接下來(lai)小(xiao)編就來(lai)介紹兩者的材質和功能間的不(bu)同：

1、一般(ban)情(qing)況下，1KV環(huan)境(jing)(jing)(jing)中(zhong)使用(yong)的(de)(de)都(dou)(dou)是(shi)低電(dian)(dian)壓母(mu)線(xian)線(xian)路(lu)，在1kV以上的(de)(de)電(dian)(dian)壓環(huan)境(jing)(jing)(jing)中(zhong)，都(dou)(dou)是(shi)高(gao)壓母(mu)線(xian)線(xian)路(lu)，當然，也有根(gen)據現場環(huan)境(jing)(jing)(jing)來(lai)決定的(de)(de)。如一般(ban)的(de)(de)配(pei)電(dian)(dian)室(shi)都(dou)(dou)是(shi)低壓母(mu)線(xian)路(lu)（注(zhu)：能(neng)夠直接與(yu)電(dian)(dian)氣設備連接，均(jun)為(wei)低壓環(huan)境(jing)(jing)(jing)，均(jun)為(wei)低壓母(mu)線(xian)路(lu)）。在送配(pei)電(dian)(dian)設備中(zhong)，變壓器前(qian)的(de)(de)高(gao)壓母(mu)線(xian)都(dou)(dou)是(shi)高(gao)壓母(mu)線(xian)，與(yu)外部高(gao)壓電(dian)(dian)線(xian)連接，在這些部位使用(yong)高(gao)壓母(mu)線(xian)線(xian)路(lu)。

2、低壓(ya)(ya)母線槽用于低壓(ya)(ya)環境，高(gao)(gao)壓(ya)(ya)母線槽用于高(gao)(gao)壓(ya)(ya)環境，低壓(ya)(ya)母線槽必須通過(guo)CCC認證，普通民眾無法(fa)獲得高(gao)(gao)壓(ya)(ya)母線槽，不需(xu)要強(qiang)制性CCC認證。

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(da)型變(bian)電站和大(da)型企業，具有安全、美觀(guan)、可靠的(de)(de)特點(dian)，因為高(gao)壓(ya)(ya)母線的(de)(de)外殼是(shi)封(feng)閉的(de)(de)，可以大(da)大(da)減少(shao)斷(duan)電和大(da)修次(ci)數，而由于電流(liu)分布不(bu)平衡(heng)引起(qi)(qi)的(de)(de)電流(liu)分配(pei)不(bu)平衡(heng)所引起(qi)(qi)的(de)(de)故障，則(ze)可能是(shi)在輸送(song)大(da)電流(liu)時由雙、三根高(gao)壓(ya)(ya)電纜引起(qi)(qi)的(de)(de)。

這里解釋下高(gao)低壓母(mu)線、主(zhu)母(mu)線、硬母(mu)線、低壓封(feng)閉母(mu)線槽與高(gao)強封(feng)閉母(mu)線槽的相關概(gai)念：

首先(xian)，電(dian)壓(ya)等級平分為高電(dian)壓(ya)和(he)低電(dian)壓(ya)，一般的功耗為低電(dian)壓(ya)。發電(dian)廠的功率(lv)被(bei)提升(sheng)到客戶端(duan)進行傳輸(shu)，然后由(you)變壓(ya)器降低。變壓(ya)器原高壓(ya)接線(xian)為母線(xian)。

其次，具有高電(dian)壓等級的主線(xian)(xian)為(wei)母(mu)(mu)(mu)(mu)線(xian)(xian)，母(mu)(mu)(mu)(mu)線(xian)(xian)一般(ban)采用矩形(xing)或圓形(xing)截(jie)面裸導線(xian)(xian)或雙(shuang)絞(jiao)線(xian)(xian)，匯流條(tiao)用于收集、分(fen)(fen)配和(he)傳輸電(dian)能。該結構分(fen)(fen)為(wei)硬(ying)母(mu)(mu)(mu)(mu)線(xian)(xian)和(he)軟母(mu)(mu)(mu)(mu)線(xian)(xian)。硬(ying)母(mu)(mu)(mu)(mu)線(xian)(xian)也(ye)分(fen)(fen)為(wei)矩形(xing)母(mu)(mu)(mu)(mu)線(xian)(xian)和(he)管狀母(mu)(mu)(mu)(mu)線(xian)(xian)。本發明的軟母(mu)(mu)(mu)(mu)線(xian)(xian)結構簡單方便，成本低廉。對于室外，因(yin)為(wei)空間很大(da)，所以線(xian)(xian)可以擺動，并且線(xian)(xian)路到線(xian)(xian)路的距離不夠。

二、低壓母線槽絕緣電阻要求

母線槽絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)件(jian)產(chan)品(pin)的(de)(de)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)(zu)(zu)值與(yu)母(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)的(de)(de)長度、周圍環境的(de)(de)濕度和(he)溫度有(you)關(guan)，對(dui)低(di)(di)壓母(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)件(jian)進行絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)(zu)(zu)測量時，可(ke)采用500V絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)(zu)(zu)表，一般不能(neng)低(di)(di)于(yu)0.5M。國內母(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)件(jian)制造廠對(dui)每(mei)單元的(de)(de)母(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)件(jian)規定絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)(zu)(zu)不低(di)(di)于(yu)20M，通常(chang)能(neng)達到500M。每(mei)節母(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)件(jian)相與(yu)相及相與(yu)外殼之間的(de)(de)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)(zu)(zu)不低(di)(di)于(yu)20M，這(zhe)是低(di)(di)要求，通常(chang)每(mei)節母(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)(zu)(zu)值可(ke)達到500 M；每(mei)安裝好一個單元母(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)后應(ying)測量母(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)件(jian)的(de)(de)電(dian)(dian)阻(zu)(zu)(zu)，允(yun)許(xu)總絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)(zu)(zu)逐(zhu)漸下(xia)降(jiang)，但不允(yun)許(xu)有(you)突(tu)變，且總絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)電(dian)(dian)阻(zu)(zu)(zu)不應(ying)小于(yu)0.5 M 。
