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)于運(yun)行低(di)壓電纜，高(gao)壓母(mu)線槽(cao)用(yong)于輸送高(gao)壓電纜。接下來(lai)小(xiao)編就來(lai)介(jie)紹兩者的材質和功能間的不同：

1、一般情況下，1KV環(huan)境中(zhong)(zhong)使用(yong)(yong)的(de)都(dou)(dou)是(shi)(shi)低(di)電(dian)壓(ya)(ya)(ya)母(mu)線(xian)(xian)(xian)線(xian)(xian)(xian)路(lu)(lu)，在1kV以上的(de)電(dian)壓(ya)(ya)(ya)環(huan)境中(zhong)(zhong)，都(dou)(dou)是(shi)(shi)高(gao)(gao)壓(ya)(ya)(ya)母(mu)線(xian)(xian)(xian)線(xian)(xian)(xian)路(lu)(lu)，當然，也(ye)有(you)根據現場環(huan)境來決(jue)定的(de)。如一般的(de)配電(dian)室都(dou)(dou)是(shi)(shi)低(di)壓(ya)(ya)(ya)母(mu)線(xian)(xian)(xian)路(lu)(lu)（注：能夠直(zhi)接(jie)與電(dian)氣設備連(lian)接(jie)，均為低(di)壓(ya)(ya)(ya)環(huan)境，均為低(di)壓(ya)(ya)(ya)母(mu)線(xian)(xian)(xian)路(lu)(lu)）。在送配電(dian)設備中(zhong)(zhong)，變壓(ya)(ya)(ya)器前的(de)高(gao)(gao)壓(ya)(ya)(ya)母(mu)線(xian)(xian)(xian)都(dou)(dou)是(shi)(shi)高(gao)(gao)壓(ya)(ya)(ya)母(mu)線(xian)(xian)(xian)，與外部高(gao)(gao)壓(ya)(ya)(ya)電(dian)線(xian)(xian)(xian)連(lian)接(jie)，在這些部位使用(yong)(yong)高(gao)(gao)壓(ya)(ya)(ya)母(mu)線(xian)(xian)(xian)線(xian)(xian)(xian)路(lu)(lu)。

2、低壓(ya)(ya)(ya)母線槽(cao)用于低壓(ya)(ya)(ya)環境(jing)，高壓(ya)(ya)(ya)母線槽(cao)用于高壓(ya)(ya)(ya)環境(jing)，低壓(ya)(ya)(ya)母線槽(cao)必(bi)須通(tong)過CCC認(ren)證，普通(tong)民眾(zhong)無法獲(huo)得高壓(ya)(ya)(ya)母線槽(cao)，不需要強制性(xing)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(yu)大(da)(da)型變(bian)電(dian)(dian)站和大(da)(da)型企(qi)業，具有安全、美觀(guan)、可靠的特點，因為高(gao)壓(ya)母線的外(wai)殼是(shi)封(feng)閉的，可以大(da)(da)大(da)(da)減(jian)少斷(duan)電(dian)(dian)和大(da)(da)修(xiu)次(ci)數，而(er)由于(yu)電(dian)(dian)流分(fen)布不平衡引(yin)(yin)起(qi)的電(dian)(dian)流分(fen)配不平衡所引(yin)(yin)起(qi)的故障(zhang)，則可能(neng)是(shi)在輸送大(da)(da)電(dian)(dian)流時(shi)由雙、三根(gen)高(gao)壓(ya)電(dian)(dian)纜引(yin)(yin)起(qi)的。

這里解(jie)釋下高低(di)壓(ya)(ya)母線(xian)(xian)、主母線(xian)(xian)、硬(ying)母線(xian)(xian)、低(di)壓(ya)(ya)封閉(bi)母線(xian)(xian)槽(cao)與高強封閉(bi)母線(xian)(xian)槽(cao)的(de)相關概(gai)念(nian)：

首先，電(dian)(dian)(dian)壓等級平分為(wei)(wei)高電(dian)(dian)(dian)壓和低(di)電(dian)(dian)(dian)壓，一(yi)般的功耗為(wei)(wei)低(di)電(dian)(dian)(dian)壓。發電(dian)(dian)(dian)廠的功率被提升到客戶端(duan)進(jin)行傳輸，然后由變(bian)壓器降低(di)。變(bian)壓器原高壓接線為(wei)(wei)母線。

其次，具有高電(dian)壓等(deng)級的主線(xian)(xian)(xian)(xian)為(wei)(wei)母(mu)(mu)線(xian)(xian)(xian)(xian)，母(mu)(mu)線(xian)(xian)(xian)(xian)一般采用矩(ju)形或圓(yuan)形截面裸導線(xian)(xian)(xian)(xian)或雙絞線(xian)(xian)(xian)(xian)，匯(hui)流條用于收(shou)集(ji)、分(fen)配和(he)傳輸(shu)電(dian)能。該結(jie)(jie)構(gou)分(fen)為(wei)(wei)硬母(mu)(mu)線(xian)(xian)(xian)(xian)和(he)軟母(mu)(mu)線(xian)(xian)(xian)(xian)。硬母(mu)(mu)線(xian)(xian)(xian)(xian)也分(fen)為(wei)(wei)矩(ju)形母(mu)(mu)線(xian)(xian)(xian)(xian)和(he)管狀母(mu)(mu)線(xian)(xian)(xian)(xian)。本(ben)發明的軟母(mu)(mu)線(xian)(xian)(xian)(xian)結(jie)(jie)構(gou)簡(jian)單方便(bian)，成本(ben)低廉。對于室外，因為(wei)(wei)空(kong)間很(hen)大，所以(yi)線(xian)(xian)(xian)(xian)可以(yi)擺動(dong)，并且線(xian)(xian)(xian)(xian)路(lu)到線(xian)(xian)(xian)(xian)路(lu)的距離不夠(gou)。

二、低壓母線槽絕緣電阻要求

母線槽絕(jue)(jue)(jue)(jue)緣件(jian)產品的(de)(de)(de)(de)絕(jue)(jue)(jue)(jue)緣電(dian)阻(zu)(zu)(zu)(zu)值(zhi)與(yu)(yu)母(mu)線(xian)(xian)槽(cao)(cao)的(de)(de)(de)(de)長度(du)、周(zhou)圍(wei)環境的(de)(de)(de)(de)濕度(du)和溫度(du)有關，對低(di)壓母(mu)線(xian)(xian)槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣件(jian)進行絕(jue)(jue)(jue)(jue)緣電(dian)阻(zu)(zu)(zu)(zu)測(ce)量(liang)時，可采(cai)用500V絕(jue)(jue)(jue)(jue)緣電(dian)阻(zu)(zu)(zu)(zu)表(biao)，一般不能低(di)于(yu)0.5M。國內母(mu)線(xian)(xian)槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣件(jian)制造廠對每單元的(de)(de)(de)(de)母(mu)線(xian)(xian)槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣件(jian)規定絕(jue)(jue)(jue)(jue)緣電(dian)阻(zu)(zu)(zu)(zu)不低(di)于(yu)20M，通常能達到500M。每節母(mu)線(xian)(xian)槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣件(jian)相與(yu)(yu)相及(ji)相與(yu)(yu)外殼之間的(de)(de)(de)(de)絕(jue)(jue)(jue)(jue)緣電(dian)阻(zu)(zu)(zu)(zu)不低(di)于(yu)20M，這(zhe)是(shi)低(di)要求，通常每節母(mu)線(xian)(xian)槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣電(dian)阻(zu)(zu)(zu)(zu)值(zhi)可達到500 M；每安裝好(hao)一個(ge)單元母(mu)線(xian)(xian)槽(cao)(cao)后應(ying)(ying)測(ce)量(liang)母(mu)線(xian)(xian)槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣件(jian)的(de)(de)(de)(de)電(dian)阻(zu)(zu)(zu)(zu)，允(yun)許總(zong)絕(jue)(jue)(jue)(jue)緣電(dian)阻(zu)(zu)(zu)(zu)逐漸下降(jiang)，但不允(yun)許有突變(bian)，且總(zong)絕(jue)(jue)(jue)(jue)緣電(dian)阻(zu)(zu)(zu)(zu)不應(ying)(ying)小(xiao)于(yu)0.5 M 。
