局端通(tong)(tong)訊設備(bei)還是(shi)(shi)(shi)(shi)用(yong)-48V電(dian)(dian)(dian)源。同樣(yang)，采(cai)用(yong)負(fu)電(dian)(dian)(dian)源系統,正(zheng)極接地(di)只是(shi)(shi)(shi)(shi)約定俗成。原來(lai)有(you)(you)個說法是(shi)(shi)(shi)(shi)空氣中有(you)(you)大量的(de)(de)負(fu)電(dian)(dian)(dian)荷，根據(ju)電(dian)(dian)(dian)化學知識，正(zheng)極接地(di)可以吸(xi)附(fu)空氣中的(de)(de)負(fu)離子，從而保護電(dian)(dian)(dian)信設備(bei)的(de)(de)外殼不(bu)(bu)被銹蝕(shi)。其實(shi)這種說法不(bu)(bu)是(shi)(shi)(shi)(shi)很對。原電(dian)(dian)(dian)池反(fan)應和電(dian)(dian)(dian)解反(fan)應是(shi)(shi)(shi)(shi)會(hui)導致設備(bei)生銹，但是(shi)(shi)(shi)(shi)因為它們在設備(bei)上是(shi)(shi)(shi)(shi)以微觀(guan)形式存在的(de)(de)，幾乎沒有(you)(you)影響。例如非通(tong)(tong)訊系統的(de)(de)網絡都是(shi)(shi)(shi)(shi)負(fu)極接地(di)（例如您正(zheng)在使用(yong)的(de)(de)計(ji)算機），但是(shi)(shi)(shi)(shi)并沒有(you)(you)生銹。并且-48V內部都通(tong)(tong)過DC/DC隔離，DC/DC輸出(chu)的(de)(de)就是(shi)(shi)(shi)(shi)負(fu)極接地(di)，也沒有(you)(you)看(kan)到單板(ban)腐蝕(shi)生銹。所以不(bu)(bu)論哪個極接地(di)，都是(shi)(shi)(shi)(shi)一樣(yang)的(de)(de)。充電(dian)(dian)(dian)電(dian)(dian)(dian)源常采(cai)用(yong)單相（或(huo)三相）半控整(zheng)(zheng)流(liu)(liu)(liu)電(dian)(dian)(dian)路(lu)或(huo)不(bu)(bu)控整(zheng)(zheng)流(liu)(liu)(liu)電(dian)(dian)(dian)路(lu)加接交流(liu)(liu)(liu)調壓器(qi)的(de)(de)整(zheng)(zheng)流(liu)(liu)(liu)電(dian)(dian)(dian)路(lu)。山東電(dian)(dian)(dian)源多少錢
