通(tong)信电(dian)源(yuan)为(wei)(wei)什(shen)么是(shi)(shi)-48V里面包含2个意思：（1）极性为(wei)(wei)何是(shi)(shi)负(fu)电(dian)源(yuan)（也(ye)就是(shi)(shi)正接(jie)地）？（2）电(dian)压为(wei)(wei)何为(wei)(wei)-48V（-36~-72V）？先说一下第2个问(wen)题。使用-48V电(dian)源(yuan)是(shi)(shi)历史原(yuan)因造成的。使用**早(zao)(zao)的通(tong)讯(xun)网是(shi)(shi)电(dian)话(hua)(hua)网，话(hua)(hua)机是(shi)(shi)由电(dian)讯(xun)局供(gong)电(dian)的，选48V是(shi)(shi)在当时的条件下尽可(ke)能(neng)提高用户到端(duan)局的距离（36V是(shi)(shi)安(an)全电(dian)压，超过太多不(bu)安(an)全）。后来为(wei)(wei)了(le)兼容早(zao)(zao)期设备、降低(di)成本(ben)考虑，局端(duan)通(tong)讯(xun)设备还是(shi)(shi)用-48V电(dian)源(yuan)。同样，采用负(fu)电(dian)源(yuan)系(xi)统,正极接(jie)地只是(shi)(shi)约定俗成。原(yuan)来有(you)个说法是(shi)(shi)空气(qi)中(zhong)有(you)大量(liang)的负(fu)电(dian)荷，根据电(dian)化学知(zhi)识(shi)，正极接(jie)地可(ke)以吸附空气(qi)中(zhong)的负(fu)离子，从而保护电(dian)信设备的外壳不(bu)被(bei)锈蚀(shi)。其实这种说法不(bu)是(shi)(shi)很对。直流输出电(dian)压能(neng)从蓄电(dian)池放电(dian)完毕时的低(di)电(dian)压到平均充电(dian)电(dian)压范(fan)围内方便地调节。天津电(dian)源(yuan)厂商
