，具(ju)備一定的(de)保護能(neng)力，斷路器的(de)接通(tong)/分斷能(neng)力比繼電器高很多。

在供配電技術里的存在有(you)雙(shuang)電源和雙(shuang)回路，那什(shen)(shen)么(me)是(shi)雙(shuang)電源，什(shen)(shen)么(me)是(shi)雙(shuang)回路，有(you)什(shen)(shen)么(me)作用，兩者(zhe)之(zhi)間的關系是(shi)什(shen)(shen)么(me)？

①雙(shuang)電(dian)(dian)源(yuan)(yuan)是(shi)指(zhi)相(xiang)(xiang)對互相(xiang)(xiang)獨立的(de)兩(liang)個電(dian)(dian)源(yuan)(yuan)。對負荷用(yong)戶或(huo)負荷設備(bei)而言所(suo)謂的(de)雙(shuang)電(dian)(dian)源(yuan)(yuan)包含著(zhu)兩(liang)層意思：一是(shi)雙(shuang)電(dian)(dian)源(yuan)(yuan)，二是(shi)回(hui)(hui)路(lu)（可能(neng)距離會很短，例如自帶蓄電(dian)(dian)池的(de)應急(ji)燈）；它(ta)既強調兩(liang)個電(dian)(dian)源(yuan)(yuan)的(de)互相(xiang)(xiang)備(bei)用(yong)或(huo)一用(yong)一備(bei)，又(you)強調兩(liang)回(hui)(hui)線路(lu)的(de)互相(xiang)(xiang)備(bei)用(yong)或(huo)一用(yong)一備(bei)。②雙(shuang)回(hui)(hui)路(lu)則(ze)只是(shi)指(zhi)兩(liang)回(hui)(hui)線路(lu)，它(ta)只強調供(gong)配電(dian)(dian)線路(lu)的(de)互相(xiang)(xiang)備(bei)用(yong)或(huo)一用(yong)一備(bei)，它(ta)對電(dian)(dian)源(yuan)(yuan)無(wu)要求，即指(zhi)此雙(shuang)回(hui)(hui)路(lu)可以由一個公(gong)共的(de)電(dian)(dian)源(yuan)(yuan)供(gong)電(dian)(dian)，也可以由兩(liang)個不同的(de)電(dian)(dian)源(yuan)(yuan)供(gong)電(dian)(dian)。

雙回路供(gong)電一般是由主(zhu)(zhu)母(mu)線(xian)(xian)和應(ying)急(ji)或備用母(mu)線(xian)(xian)同時供(gong)電，正(zheng)常(chang)情況(kuang)下由主(zhu)(zhu)母(mu)線(xian)(xian)取電，主(zhu)(zhu)母(mu)線(xian)(xian)檢修、

損壞(huai)或遇電(dian)(dian)源停電(dian)(dian)等主母線失電(dian)(dian)情況下切換(huan)至(zhi)應急或備(bei)用母線供電(dian)(dian)，

此切換對于

一級負荷和特別(bie)重要負荷在(zai)供電末端進行(xing)。
