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(yu)運行(xing)低壓(ya)(ya)電纜(lan)，高壓(ya)(ya)母(mu)線(xian)槽用于(yu)輸(shu)送高壓(ya)(ya)電纜(lan)。接下來小編就來介(jie)紹(shao)兩者的材(cai)質和功能間的不同：

1、一般情況下(xia)，1KV環境(jing)中使(shi)用的都(dou)(dou)是低電(dian)(dian)壓(ya)(ya)(ya)(ya)母(mu)線(xian)線(xian)路(lu)(lu)，在1kV以上的電(dian)(dian)壓(ya)(ya)(ya)(ya)環境(jing)中，都(dou)(dou)是高(gao)壓(ya)(ya)(ya)(ya)母(mu)線(xian)線(xian)路(lu)(lu)，當然，也(ye)有根據(ju)現場環境(jing)來決定(ding)的。如一般的配電(dian)(dian)室都(dou)(dou)是低壓(ya)(ya)(ya)(ya)母(mu)線(xian)路(lu)(lu)（注：能夠直接與電(dian)(dian)氣設備連(lian)接，均(jun)為低壓(ya)(ya)(ya)(ya)環境(jing)，均(jun)為低壓(ya)(ya)(ya)(ya)母(mu)線(xian)路(lu)(lu)）。在送(song)配電(dian)(dian)設備中，變(bian)壓(ya)(ya)(ya)(ya)器前的高(gao)壓(ya)(ya)(ya)(ya)母(mu)線(xian)都(dou)(dou)是高(gao)壓(ya)(ya)(ya)(ya)母(mu)線(xian)，與外(wai)部高(gao)壓(ya)(ya)(ya)(ya)電(dian)(dian)線(xian)連(lian)接，在這些部位使(shi)用高(gao)壓(ya)(ya)(ya)(ya)母(mu)線(xian)線(xian)路(lu)(lu)。

2、低壓母(mu)線(xian)槽(cao)用于(yu)低壓環境，高壓母(mu)線(xian)槽(cao)用于(yu)高壓環境，低壓母(mu)線(xian)槽(cao)必須(xu)通過CCC認證(zheng)，普通民眾無(wu)法獲得(de)高壓母(mu)線(xian)槽(cao)，不(bu)需要(yao)強制性CCC認證(zheng)。

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)(da)型變(bian)電(dian)站和大(da)(da)(da)型企業，具有安全、美觀、可靠的(de)(de)(de)(de)(de)特(te)點，因為高壓母線的(de)(de)(de)(de)(de)外殼是(shi)封閉(bi)的(de)(de)(de)(de)(de)，可以大(da)(da)(da)大(da)(da)(da)減少斷電(dian)和大(da)(da)(da)修次數，而由于(yu)電(dian)流分布不(bu)平(ping)衡引(yin)起的(de)(de)(de)(de)(de)電(dian)流分配不(bu)平(ping)衡所引(yin)起的(de)(de)(de)(de)(de)故障(zhang)，則可能是(shi)在輸送大(da)(da)(da)電(dian)流時(shi)由雙(shuang)、三根高壓電(dian)纜引(yin)起的(de)(de)(de)(de)(de)。

這里解(jie)釋下高(gao)低壓(ya)母(mu)線(xian)(xian)、主(zhu)母(mu)線(xian)(xian)、硬母(mu)線(xian)(xian)、低壓(ya)封閉(bi)母(mu)線(xian)(xian)槽與高(gao)強封閉(bi)母(mu)線(xian)(xian)槽的(de)相關概念：

首先，電(dian)壓(ya)(ya)等(deng)級平分為高電(dian)壓(ya)(ya)和低電(dian)壓(ya)(ya)，一般的(de)功(gong)耗為低電(dian)壓(ya)(ya)。發電(dian)廠的(de)功(gong)率(lv)被提升(sheng)到(dao)客(ke)戶(hu)端進行(xing)傳輸(shu)，然后由(you)變壓(ya)(ya)器(qi)降低。變壓(ya)(ya)器(qi)原高壓(ya)(ya)接線(xian)為母線(xian)。

其次，具有高電壓等(deng)級(ji)的(de)主線(xian)為(wei)母(mu)(mu)(mu)線(xian)，母(mu)(mu)(mu)線(xian)一(yi)般采(cai)用矩(ju)形(xing)或圓形(xing)截面裸導線(xian)或雙絞線(xian)，匯流條用于收集、分配和傳輸(shu)電能(neng)。該結構分為(wei)硬(ying)母(mu)(mu)(mu)線(xian)和軟母(mu)(mu)(mu)線(xian)。硬(ying)母(mu)(mu)(mu)線(xian)也分為(wei)矩(ju)形(xing)母(mu)(mu)(mu)線(xian)和管狀(zhuang)母(mu)(mu)(mu)線(xian)。本(ben)發明的(de)軟母(mu)(mu)(mu)線(xian)結構簡單(dan)方便，成本(ben)低(di)廉。對于室外，因為(wei)空間很(hen)大，所以線(xian)可以擺動，并且線(xian)路到線(xian)路的(de)距(ju)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)(yuan)件(jian)(jian)產品的(de)(de)(de)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)電(dian)阻(zu)(zu)(zu)值與(yu)母(mu)(mu)線槽(cao)(cao)的(de)(de)(de)長度、周圍環(huan)境的(de)(de)(de)濕度和溫度有關(guan)，對(dui)低(di)(di)(di)(di)壓母(mu)(mu)線槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)件(jian)(jian)進行絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)電(dian)阻(zu)(zu)(zu)測量時，可(ke)采用500V絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)電(dian)阻(zu)(zu)(zu)表(biao)，一般不(bu)能(neng)(neng)低(di)(di)(di)(di)于0.5M。國內(nei)母(mu)(mu)線槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)件(jian)(jian)制造廠(chang)對(dui)每(mei)單元的(de)(de)(de)母(mu)(mu)線槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)件(jian)(jian)規定(ding)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)電(dian)阻(zu)(zu)(zu)不(bu)低(di)(di)(di)(di)于20M，通常能(neng)(neng)達(da)到(dao)500M。每(mei)節母(mu)(mu)線槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)件(jian)(jian)相與(yu)相及相與(yu)外殼之間的(de)(de)(de)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)電(dian)阻(zu)(zu)(zu)不(bu)低(di)(di)(di)(di)于20M，這是(shi)低(di)(di)(di)(di)要求，通常每(mei)節母(mu)(mu)線槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)電(dian)阻(zu)(zu)(zu)值可(ke)達(da)到(dao)500 M；每(mei)安裝好一個單元母(mu)(mu)線槽(cao)(cao)后(hou)應測量母(mu)(mu)線槽(cao)(cao)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)件(jian)(jian)的(de)(de)(de)電(dian)阻(zu)(zu)(zu)，允(yun)許總絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)電(dian)阻(zu)(zu)(zu)逐漸下(xia)降，但不(bu)允(yun)許有突變，且總絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)電(dian)阻(zu)(zu)(zu)不(bu)應小于0.5 M 。
