| 概述 Application （） |
| DTSY345型三相電子式電能表是采用進(jìn)口專用大規(guī)模偏大集成電路，16位A／D轉(zhuǎn)換、數(shù)字乘法器、應(yīng)用數(shù)字采樣處理技術(shù)及SMT工藝，根據(jù)工業(yè)用戶實(shí)際用電狀況所設(shè)計(jì)、制造的新型儀表。該表采用立三單元計(jì)量模塊能地測量三相正向和反向的有功電能。計(jì)量誤差具有優(yōu)異的長期穩(wěn)定性。選用高品質(zhì)鉭電容、使用壽命長。防止了三相表在使用中由于接線時(shí)的相序錯(cuò)誤、電流反向、電壓電流不同相、電壓斷開、零線斷開等造成的計(jì)量誤差的竊電行為。其性能符合GB／T18460.3-2001。三相電能表的各項(xiàng)技術(shù)要求。其用途計(jì)量額定頻率為50~60Hz的三相有功電能。
DTSY345 three—phase static watt—hour meter makes use of importing special large—scale jntegrate circuit 16 digit A／D changeover，digital multiplier,sampling and handling technology of digit and SMT technology,it is a new meterdesigned and manufactured according to users’real situation of power utilization Because of employing independentthree．unit measuring module it iS able to measure three phase positive and negative active energy accurately Themeasuring error has excellent long—time stability Top quality Ta capacitance iS selected for the watt-hour meter,so its service life iS quite Iong and it can prevent thieving actions from error phase Sequence current reversing different phase between voltage and current．voltage breaking，zero wire breaking．its perfo rmance conforms to each itern technicaI requirement of three—phase watt—hour meter stipulated in GB/T18460 3—2001 idt IEC 1036—1996 Its purpose is to measure three-phase active energy of rated frequency 50-60HZ． |
