無線計量電表是主要用于計量低壓網絡的三相有功電能，并可選配RS485通訊功能，方便用戶進行用電監測、集抄和管理。產品具有精度高、體積小、安裝方便等優點。可靈活安裝于配電箱內，實現對不同區域和不同負荷的分項電能計量，統計和分析。 無線計(ji)量(liang)電(dian)(dian)(dian)(dian)(dian)(dian)表(biao)既(ji)可以(yi)改裝(zhuang)成(cheng)(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓表(biao)，又可以(yi)改裝(zhuang)成(cheng)(cheng)(cheng)量(liang)程(cheng)較大(da)的電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)表(biao)，也可以(yi)改裝(zhuang)成(cheng)(cheng)(cheng)歐姆表(biao)。如將它們適當組合起來，它們可以(yi)共用(yong)一個(ge)表(biao)頭，就成(cheng)(cheng)(cheng)為一個(ge)多用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)表(biao)。多用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)表(biao)可以(yi)分為有普(pu)通多用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)表(biao)和數(shu)字(zi)式多用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)表(biao)。用(yong)途：測量(liang)交(jiao)流(liu)/直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓、交(jiao)流(liu)/直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)、電(dian)(dian)(dian)(dian)(dian)(dian)阻阻值、電(dian)(dian)(dian)(dian)(dian)(dian)容器容量(liang)、電(dian)(dian)(dian)(dian)(dian)(dian)感量(liang)、音頻電(dian)(dian)(dian)(dian)(dian)(dian)平、頻率、晶(jing)體(ti)管NPN或PNP電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)放大(da)倍數(shu)β值等。
峰值(zhi)波(bo)長(chang)是(shi)指紅外(wai)發光(guang)二極(ji)管所發出近紅外(wai)光(guang)中光(guang)^Pubi尬接收(shou)器在(zai)其(qi)光(guang)軸上距接收(shou)器表(biao)面10mm處紅外(wai)光(guang)大值(zhi)所對(dui)應的發光(guang)波(bo)長(chang)。在(zai)遠距離紅外(wai)通(tong)訊中，一(yi)般選(xuan)用波(bo)長(chang)為(wei)940nm或950nm的紅外(wai)發射二極(ji)管。
無線計(ji)量電表(biao)的性能優點：
1、電(dian)(dian)能表運(yun)行信息可由手持(chi)電(dian)(dian)腦、RS485接口、國際標準IC卡三(san)種媒介傳輸，電(dian)(dian)力部門可根(gen)據本地(di)區具體情況自(zi)行選擇一種或多(duo)種傳輸方式。
2、電(dian)能表(biao)的(de)(de)線路設計和(he)元器件的(de)(de)選擇(ze)以(yi)較(jiao)大的(de)(de)環(huan)境允許誤差為(wei)依據，因此可(ke)保(bao)證整機長期(qi)穩定工作(zuo)；精度基本不(bu)受頻率、溫度、電(dian)壓(ya)變化影響；整機體積小，重(zhong)量輕，密封性能好，可(ke)靠性較(jiao)其他(ta)同類(lei)產(chan)品有明顯(xian)提高。
3、當電(dian)(dian)網停電(dian)(dian)后(hou)(hou)(hou)，鋰(li)電(dian)(dian)池作為后(hou)(hou)(hou)備(bei)電(dian)(dian)源(yuan)，提供(gong)停電(dian)(dian)后(hou)(hou)(hou)表(biao)內電(dian)(dian)量(liang)的顯示讀取，并保證內部數據(ju)不(bu)丟失，日歷、時(shi)鐘(zhong)、時(shi)段程序控(kong)制(zhi)功能正常運行(xing)，來(lai)電(dian)(dian)后(hou)(hou)(hou)自動投(tou)入運行(xing)。在電(dian)(dian)能表(biao)端鈕盒上設置(zhi)有(you)光電(dian)(dian)耦合脈沖輸出接口，以便于進行(xing)誤差(cha)測試和數據(ju)采集(ji)。
4、為方便用戶現場更換電能表，使用表中*的復印功能，可以方便地將被更換表的所有信息復印至更換后的電能表上，可靠，簡化了用戶更換電能表的工作程序，提高了工作效率。
