        在(zai)城市軌(gui)道交通(tong)(tong)通(tong)(tong)信(xin)中其48v通(tong)(tong)信(xin)電(dian)(dian)源(yuan)(yuan)起(qi)到(dao)的(de)(de)作用是(shi)十分重要(yao)(yao)的(de)(de),他的(de)(de)功能就是(shi)保證其穩定、可(ke)靠(kao)和安全(quan)(quan)。穩定要(yao)(yao)求(qiu)其供電(dian)(dian)的(de)(de)電(dian)(dian)壓和頻(pin)率的(de)(de)波動(dong)都必須在(zai)其允許的(de)(de)范(fan)圍之內(nei)。可(ke)靠(kao)電(dian)(dian)源(yuan)(yuan)是(shi)指能保證晝(zhou)夜不間斷供電(dian)(dian)的(de)(de)獨立(li)電(dian)(dian)源(yuan)(yuan)。安全(quan)(quan)是(shi)指電(dian)(dian)源(yuan)(yuan)設備要(yao)(yao)采取保障(zhang)安全(quan)(quan)的(de)(de)措施。 

       首先我們(men)要(yao)保(bao)證城市軌道(dao)交(jiao)(jiao)通48v通信(xin)(xin)電(dian)(dian)(dian)源系(xi)統(tong)必須是(shi)獨(du)立(li)的供電(dian)(dian)(dian)系(xi)統(tong),必須要(yao)滿(man)(man)足(zu)第一類(lei)電(dian)(dian)(dian)源要(yao)求(qiu),取(qu)得兩路可(ke)靠獨(du)立(li)的電(dian)(dian)(dian)源,其中一路為專盤(pan)專線。當(dang)然還要(yao)城市軌道(dao)交(jiao)(jiao)通通信(xin)(xin)電(dian)(dian)(dian)源設備(bei)應滿(man)(man)足(zu)通信(xin)(xin)設備(bei)對電(dian)(dian)(dian)源可(ke)靠性的要(yao)求(qiu)。滿(man)(man)足(zu)其不間斷供電(dian)(dian)(dian)的需求(qiu)。最后對要(yao)求(qiu)直(zhi)(zhi)流(liu)(liu)供電(dian)(dian)(dian)的通信(xin)(xin)設備(bei),應采用(yong)集(ji)中方式(shi)供電(dian)(dian)(dian)。直(zhi)(zhi)流(liu)(liu)48v通信(xin)(xin)電(dian)(dian)(dian)源系(xi)統(tong)可(ke)由直(zhi)(zhi)流(liu)(liu)配電(dian)(dian)(dian)盤(pan)、整流(liu)(liu)模塊、直(zhi)(zhi)流(liu)(liu)變換器、逆變器、閥控式(shi)密閉鉛蓄(xu)電(dian)(dian)(dian)池(chi)組組合(he)機架組成,并應具有遙信(xin)(xin)、遙測(ce)、遙控性能(neng)和標準的接口及通信(xin)(xin)協議。
