得(de)潤電氣有著三十年(nian)的(de)(de)開(kai)(kai)發經驗和雄厚的(de)(de)技(ji)術團隊，為了廣大客(ke)戶朋(peng)友能夠選(xuan)到性價皆優的(de)(de)開(kai)(kai)關柜，特在本(ben)文中為大家分享低壓開(kai)(kai)關柜的(de)(de)電力載波通訊方(fang)式(shi)，如下：

低壓開關柜采用低(di)(di)壓(ya)智能復(fu)合開(kai)關為執(zhi)行(xing)元件(jian)控制(zhi)(zhi)電(dian)(dian)容(rong)器(qi)的(de)(de)(de)投(tou)切。智能復(fu)合開(kai)關是針對(dui)(dui)晶(jing)閘管無觸點開(kai)關和交流(liu)(liu)接(jie)觸器(qi)在(zai)低(di)(di)壓(ya)無功補償應用中(zhong)的(de)(de)(de)不足而研制(zhi)(zhi)的(de)(de)(de)。它將2種器(qi)件(jian)的(de)(de)(de)優(you)(you)點融為一(yi)體，回避了晶(jing)閘管無觸點開(kai)關或固(gu)態繼(ji)電(dian)(dian)器(qi)及交流(liu)(liu)接(jie)觸器(qi)這2種器(qi)件(jian)的(de)(de)(de)缺點，既能實現過零投(tou)切的(de)(de)(de)功能，又可保(bao)證開(kai)關導(dao)通(tong)期(qi)間無電(dian)(dian)能損耗，無浪涌電(dian)(dian)流(liu)(liu)，對(dui)(dui)電(dian)(dian)容(rong)和電(dian)(dian)網(wang)無沖(chong)擊，大幅(fu)提高電(dian)(dian)容(rong)器(qi)的(de)(de)(de)壽命和系統的(de)(de)(de)穩(wen)定(ding)性(xing)。PLC是一(yi)種電(dian)(dian)力線(xian)(xian)(xian)和通(tong)信(xin)線(xian)(xian)(xian)復(fu)用的(de)(de)(de)通(tong)信(xin)形式，具有(you)投(tou)資少(shao)、傳輸速率(lv)高、使用方(fang)便(bian)、費用低(di)(di)、永(yong)遠在(zai)線(xian)(xian)(xian)等優(you)(you)點。在(zai)配電(dian)(dian)網(wang)中(zhong)利(li)用電(dian)(dian)力線(xian)(xian)(xian)通(tong)信(xin)，可以加速自動化的(de)(de)(de)進程，充分(fen)利(li)用電(dian)(dian)力系統自身(shen)的(de)(de)(de)資源。為保(bao)護提供通(tong)信(xin)，有(you)利(li)于形成開(kai)放式計算機(ji)通(tong)信(xin)網(wang)絡。

目前，中壓PLC主(zhu)要(yao)利用10 kV電(dian)(dian)力(li)(li)線(xian)(xian)(xian)作(zuo)為(wei)通(tong)(tong)信(xin)鏈路(lu)，為(wei)接人(ren)骨干網、配網自動化系(xi)統(tong)(tong)等提供數(shu)據(ju)傳輸(shu)通(tong)(tong)道(dao)；低(di)壓(ya)(ya)PLC利用380V／220 V電(dian)(dian)力(li)(li)線(xian)(xian)(xian)為(wei)傳輸(shu)媒介(jie)，主(zhu)要(yao)作(zuo)為(wei)用戶電(dian)(dian)網集中遠程自動抄(chao)表系(xi)統(tong)(tong)的(de)(de)(de)(de)數(shu)據(ju)傳輸(shu)通(tong)(tong)道(dao)。低(di)壓(ya)(ya)開關柜由于電(dian)(dian)力(li)(li)線(xian)(xian)(xian)并不是專(zhuan)為(wei)傳輸(shu)信(xin)號(hao)而設計(ji)的(de)(de)(de)(de)，因此有必要(yao)考慮(lv)影(ying)響PLC傳輸(shu)質(zhi)量的(de)(de)(de)(de)幾點主(zhu)要(yao)因素：電(dian)(dian)力(li)(li)網絡的(de)(de)(de)(de)阻抗特性(xing)、衰減特性(xing)、噪聲干擾，以(yi)及居民區低(di)壓(ya)(ya)電(dian)(dian)網中家用電(dian)(dian)器的(de)(de)(de)(de)干擾。電(dian)(dian)力(li)(li)線(xian)(xian)(xian)上“因地而變”的(de)(de)(de)(de)干擾特性(xing)非(fei)常復(fu)雜，且隨機性(xing)、時變性(xing)大，難(nan)以(yi)找到一個較準確的(de)(de)(de)(de)解析式(shi)和數(shu)學模型加以(yi)描述(shu)，需(xu)結合實際情況，采(cai)用多種技術(shu)措施，才能(neng)達到滿意的(de)(de)(de)(de)載(zai)波通(tong)(tong)信(xin)效(xiao)果。依靠低(di)壓(ya)(ya)PLC通(tong)(tong)信(xin)技術(shu)發(fa)展起(qi)來的(de)(de)(de)(de)集中抄(chao)表應用系(xi)統(tong)(tong)，能(neng)實現(xian)臺(tai)區電(dian)(dian)費的(de)(de)(de)(de)遠間隔(ge)集中抄(chao)錄，監控對臺(tai)區總電(dian)(dian)量、線(xian)(xian)(xian)損(sun)的(de)(de)(de)(de)統(tong)(tong)計(ji)和計(ji)算，有效(xiao)緩解了抄(chao)／收電(dian)(dian)費工(gong)作(zuo)量大的(de)(de)(de)(de)問題。

安徽得(de)潤(run)(run)電(dian)氣(qi)的(de)低開關柜(ju)(ju)均采用(yong)上乘的(de)敷鋁鋅板，引(yin)進(jin)國(guo)外先進(jin)技(ji)術。得(de)潤(run)(run)電(dian)氣(qi)高(gao)低壓開關柜(ju)(ju)獲得(de)十余項國(guo)家專(zhuan)利(li)，綜合新技(ji)術、新工藝(yi)，不(bu)(bu)斷推(tui)陳(chen)出(chu)新，持續為客(ke)戶(hu)提供更(geng)高(gao)品(pin)質的(de)產品(pin)。得(de)潤(run)(run)高(gao)低壓開關柜(ju)(ju)廣泛應用(yong)于建材(cai)、冶金、電(dian)力(li)、化工、船舶、鐵路、輕工業(ye)等多行業(ye)。如此雄厚(hou)的(de)力(li)量您不(bu)(bu)容錯過。
