Ol 'single-phase pawa mita em ol bikpela samting bilong skelim pawa we ol manmeri i save yusim long haus na ol liklik bisnis. Pefomens na reliabiliti bilong ol i stret wantaim stretpela pasin bilong ol setelmen bilong pawa tred. Long mekim wok skelim i kamap stret, seif, na ol i ken senisim, ol i bin kamapim ol strongpela standet bilong bihainim long olgeta hap bilong wol. kantri bilong mi i save bihainim nesenel standet GB/T 17215 series, wantaim ol spesifikesen bilong Intanesenel Elektroteknikel Komisin (IEC).
Domestik Standet Sistem
ol 'single-phase pawa mita standet bilong kantri bilong mi i stap long GB/T 17215.211-2021, "Electrical Measuring Equipment - Dependability - Part 211: Reliability Requirements for Electricity Meters," na GB/T 17215.321-2021, "Stasenari AC Aktiv Eneji Mita (Klas 1 na 2)." Pastaim i tok klia long ol samting ol i mas mekim long ol eneji mita long sait bilong envairomen, strong bilong masin, na longpela taim operesenel stebiliti; laspela i makim ol teknikel paramita olsem 'accuracy grade', 'starting current', na 'power factor range' bilong ol Klas 1 na 2 ektiv eneji mita. Olsem, mak bilong asua bilong ol mita bilong Klas 1 em ±1%, na bilong ol mita bilong Klas 2, em i ±2%. Stretpela samting i mas stap insait long mak bilong 0.1Ib (10% bilong 'base current') i go inap long 'Imax' (maksimum 'current'). Na tu, GB/T 15284-2022 i helpim ol wok na rot bilong testim ol 'multi-rate' pawa mita, na i nidim sapot bilong 'time perioding programing' na 'data storage'.
Intanesenel Standet Harmonisesen
Long wol, IEC 62053 series bilong ol standet (olsem IEC 62053-21:2020) i wok olsem wanpela jenerel gaidlain bilong singel-feis pawa mita disain na i stret tru wantaim ol nesenel standet bilong kantri bilong mi. Ol dispela standet i tok klia long 'electromagnetic compatibility' (EMC), 'temperature' na 'humidity tolerance' (olsem, wanpela 'operating range' bilong -25 digri i go inap long +60 digri), na ol samting bilong wokim ol samting we i no inap bagarapim samting. Na tu, ol rijonal standet olsem EN 50470 bilong EU na ANSI C12.10 bilong Not Amerika i gat ol narapela narapela provisen long sait bilong 'voltage fluctuation adaptability' na ol 'communication interfaces' (olsem, infraret na RS-485). Mining na Trend bilong Implementesen
Wanpela strongpela standet sistem i mekim wok bilong skelim pawa i kamap lo na i gat gutpela teknoloji. Wantaim divelopmen bilong ol 'smart grid', ol nupela standet i wok long putim ol samting bilong HPLC komunikesen, 'remote calibration', na 'dynamic load monitoring'. Ol kampani i mas winim ol tes bilong skelim ol kain samting (olsem CNAS setifikesen tes bilong China Electric Power Research Institute) bilong lukim olsem ol i bihainim ol standet long olgeta taim bilong laipsaikel bilong prodak bilong ol. Long bihain taim, ol standet bai lukluk moa long 'low-carbon metering na netwok sekyuriti, na dispela bai kirapim ol 'electricity meters' long kamapim ol 'high precision' na 'intelligent' teknoloji.
Long tok sot, ol standet bilong implementesen bilong ol singel-feis pawa mita em i kamap long wanpela balens namel long ol teknikel spesifikasen na diman bilong maket. Wok bilong ol long wok gut oltaim i save givim gutpela teknikel sapot long global eneji menesmen.
