局端通訊設(she)備(bei)(bei)還(huan)是(shi)(shi)用-48V電(dian)(dian)(dian)(dian)源。同樣，采用負電(dian)(dian)(dian)(dian)源系統,正(zheng)極接(jie)(jie)地(di)(di)只是(shi)(shi)約定俗成。原(yuan)來有個說(shuo)法是(shi)(shi)空(kong)氣(qi)中有大量的(de)(de)負電(dian)(dian)(dian)(dian)荷，根據電(dian)(dian)(dian)(dian)化學知(zhi)識(shi)，正(zheng)極接(jie)(jie)地(di)(di)可以(yi)吸附空(kong)氣(qi)中的(de)(de)負離(li)子(zi)，從(cong)而保護電(dian)(dian)(dian)(dian)信設(she)備(bei)(bei)的(de)(de)外殼不被(bei)銹(xiu)蝕。其實這種說(shuo)法不是(shi)(shi)很(hen)對。原(yuan)電(dian)(dian)(dian)(dian)池反應和電(dian)(dian)(dian)(dian)解反應是(shi)(shi)會導(dao)致(zhi)設(she)備(bei)(bei)生銹(xiu)，但(dan)是(shi)(shi)因為它(ta)們(men)在設(she)備(bei)(bei)上(shang)(shang)是(shi)(shi)以(yi)微觀形式存在的(de)(de)，幾乎沒(mei)有影響。例如(ru)非通訊系統的(de)(de)網絡(luo)都(dou)(dou)(dou)是(shi)(shi)負極接(jie)(jie)地(di)(di)（例如(ru)您正(zheng)在使(shi)(shi)用的(de)(de)計(ji)算機(ji)），但(dan)是(shi)(shi)并沒(mei)有生銹(xiu)。并且(qie)-48V內部都(dou)(dou)(dou)通過DC/DC隔(ge)離(li)，DC/DC輸出的(de)(de)就是(shi)(shi)負極接(jie)(jie)地(di)(di)，也沒(mei)有看到單板腐蝕生銹(xiu)。所以(yi)不論哪個極接(jie)(jie)地(di)(di)，都(dou)(dou)(dou)是(shi)(shi)一(yi)樣的(de)(de)。上(shang)(shang)海智能電(dian)(dian)(dian)(dian)源充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源不能用粗暴的(de)(de)使(shi)(shi)用方(fang)式扔(reng)擲、敲擊移動電(dian)(dian)(dian)(dian)源。
