①雙(shuang)電(dian)(dian)源(yuan)(yuan)是指相對(dui)互(hu)(hu)(hu)相獨立的(de)兩(liang)個(ge)電(dian)(dian)源(yuan)(yuan)。對(dui)負荷(he)用戶或負荷(he)設備(bei)而言所謂的(de)雙(shuang)電(dian)(dian)源(yuan)(yuan)包含著兩(liang)層意思：一(yi)(yi)(yi)是雙(shuang)電(dian)(dian)源(yuan)(yuan)，二是回(hui)路（可(ke)能距離會很(hen)短(duan)，例如自帶蓄(xu)電(dian)(dian)池的(de)應急燈）；它(ta)(ta)既(ji)強(qiang)(qiang)調兩(liang)個(ge)電(dian)(dian)源(yuan)(yuan)的(de)互(hu)(hu)(hu)相備(bei)用或一(yi)(yi)(yi)用一(yi)(yi)(yi)備(bei)，又強(qiang)(qiang)調兩(liang)回(hui)線(xian)路的(de)互(hu)(hu)(hu)相備(bei)用或一(yi)(yi)(yi)用一(yi)(yi)(yi)備(bei)。②雙(shuang)回(hui)路則(ze)只(zhi)是指兩(liang)回(hui)線(xian)路，它(ta)(ta)只(zhi)強(qiang)(qiang)調供(gong)配(pei)電(dian)(dian)線(xian)路的(de)互(hu)(hu)(hu)相備(bei)用或一(yi)(yi)(yi)用一(yi)(yi)(yi)備(bei)，它(ta)(ta)對(dui)電(dian)(dian)源(yuan)(yuan)無(wu)要求，PC雙(shuang)電(dian)(dian)源(yuan)(yuan)哪家好(hao)，即指此(ci)雙(shuang)回(hui)路可(ke)以由(you)一(yi)(yi)(yi)個(ge)公共的(de)電(dian)(dian)源(yuan)(yuan)供(gong)電(dian)(dian)，也(ye)可(ke)以由(you)兩(liang)個(ge)不(bu)同的(de)電(dian)(dian)源(yuan)(yuan)供(gong)電(dian)(dian)。

在(zai)供配電(dian)技術里(li)的(de)存在(zai)有雙(shuang)電(dian)源和(he)雙(shuang)回(hui)路，那什么是(shi)雙(shuang)電(dian)源，什么是(shi)雙(shuang)回(hui)路，有什么作用(yong)，兩者(zhe)之間的(de)關系是(shi)什么？

①雙(shuang)(shuang)電(dian)源(yuan)(yuan)是(shi)指(zhi)相對(dui)互相獨立的(de)(de)兩個電(dian)源(yuan)(yuan)。對(dui)負荷用(yong)戶或負荷設備(bei)(bei)而(er)言所謂(wei)的(de)(de)雙(shuang)(shuang)電(dian)源(yuan)(yuan)包含著兩層意思(si)：一(yi)(yi)是(shi)雙(shuang)(shuang)電(dian)源(yuan)(yuan)，二是(shi)回路（可能距離會(hui)很短，例如自(zi)帶蓄電(dian)池的(de)(de)應急(ji)燈(deng)）；它(ta)既強調(diao)(diao)兩個電(dian)源(yuan)(yuan)的(de)(de)互相備(bei)(bei)用(yong)或一(yi)(yi)用(yong)一(yi)(yi)備(bei)(bei)，又強調(diao)(diao)兩回線(xian)路的(de)(de)互相備(bei)(bei)用(yong)或一(yi)(yi)用(yong)一(yi)(yi)備(bei)(bei)。②雙(shuang)(shuang)回路則只是(shi)指(zhi)兩回線(xian)路，它(ta)只強調(diao)(diao)供配電(dian)線(xian)路的(de)(de)互相備(bei)(bei)用(yong)或一(yi)(yi)用(yong)一(yi)(yi)備(bei)(bei)，它(ta)對(dui)電(dian)源(yuan)(yuan)無(wu)要(yao)求，即指(zhi)此雙(shuang)(shuang)回路可以(yi)由(you)一(yi)(yi)個公共的(de)(de)電(dian)源(yuan)(yuan)供電(dian)，也可以(yi)由(you)兩個不(bu)同的(de)(de)電(dian)源(yuan)(yuan)供電(dian)。

雙回路供(gong)電(dian)(dian)一(yi)般是由主母(mu)線(xian)和(he)應(ying)急或備用(yong)母(mu)線(xian)同時供(gong)電(dian)(dian)，正常情(qing)況下由主母(mu)線(xian)取電(dian)(dian)，主母(mu)線(xian)檢修、

損壞或(huo)遇電源停電等主母線失電情況下切換至應(ying)急或(huo)備(bei)用母線供電，

此切換對于

一級負(fu)荷和特別(bie)重要負(fu)荷在供電末端進(jin)行。
