通信(xin)電源(yuan)(yuan)為(wei)(wei)什么是(shi)(shi)(shi)(shi)-48V里面(mian)包含2個意思：（1）極性為(wei)(wei)何(he)是(shi)(shi)(shi)(shi)負電源(yuan)(yuan)（也(ye)就是(shi)(shi)(shi)(shi)正(zheng)接地）？（2）電壓為(wei)(wei)何(he)為(wei)(wei)-48V（-36~-72V）？先說一下第2個問題。使用(yong)(yong)-48V電源(yuan)(yuan)是(shi)(shi)(shi)(shi)歷史原(yuan)因造成的(de)(de)(de)。使用(yong)(yong)**早的(de)(de)(de)通訊(xun)(xun)網(wang)是(shi)(shi)(shi)(shi)電話(hua)網(wang)，話(hua)機是(shi)(shi)(shi)(shi)由電訊(xun)(xun)局供(gong)電的(de)(de)(de)，選48V是(shi)(shi)(shi)(shi)在當時(shi)的(de)(de)(de)條(tiao)件下盡可能提高(gao)用(yong)(yong)戶到(dao)端局的(de)(de)(de)距離（36V是(shi)(shi)(shi)(shi)安全電壓，超(chao)過(guo)太多(duo)不(bu)安全）。后來為(wei)(wei)了兼容早期設備、降低成本(ben)考慮，局端通訊(xun)(xun)設備還是(shi)(shi)(shi)(shi)用(yong)(yong)-48V電源(yuan)(yuan)。同樣，采用(yong)(yong)負電源(yuan)(yuan)系統,正(zheng)極接地只是(shi)(shi)(shi)(shi)約定俗成。原(yuan)來有(you)個說法是(shi)(shi)(shi)(shi)空(kong)氣中(zhong)有(you)大量的(de)(de)(de)負電荷(he)，根據電化學知識，正(zheng)極接地可以吸附空(kong)氣中(zhong)的(de)(de)(de)負離子，從(cong)而保(bao)護(hu)電信(xin)設備的(de)(de)(de)外(wai)殼不(bu)被銹蝕。其實這種(zhong)說法不(bu)是(shi)(shi)(shi)(shi)很對。直流輸(shu)出電壓能從(cong)蓄電池放電完畢時(shi)的(de)(de)(de)低電壓到(dao)平(ping)均充電電壓范圍內方便地調節(jie)。天津電源(yuan)(yuan)廠商
