Main Specifications thiab Technical Parameters of Single-Phase 485 On-Off Smart Meter
Kev ua tau zoo ntawm ib-theem 485 on-off smart meter ua tiav raws li cov kev cai tsim nyog ntawm GB / T 17215-2008 lub teb chaws tus qauv thiab GB / T 18460-2001 tus qauv rau 1 lossis 2 ib leeg- theem hluav taws xob hluav taws xob ntsuas.
1. Specification ntawm hluav taws xob ntsuas hluav taws xob:
Nco tseg: Nyob rau hauv kem ntawm rated tam sim no, tus nqi ua ntej lub brackets yog tus nqi tam sim no Ib, thiab tus nqi nyob rau hauv lub brackets yog tus nqi siab tshaj tam sim no tus nqi Imax.
2. Technical parameters:
● yuam kev txwv
● Pib
Raws li qhov xwm txheej ntawm qhov ntsuas hluav taws xob, ntsuas qhov zaus thiab lub zog ntawm 1, thaum lub sijhawm thauj khoom ntawm lub ntsuas hluav taws xob yog tus nqi teev nyob rau hauv cov lus hauv qab no, lub ntsuas hluav taws xob hluav taws xob yuav tsum muaj peev xwm pib thiab ntsuas qhov hluav taws xob tsis tu ncua.
● nyiag
Thaum tsis muaj tam sim no ntawm kab tam sim no ntawm lub ntsuas hluav taws xob hluav taws xob, thiab qhov hluav taws xob siv rau cov kab hluav taws xob yog 115 feem pua ntawm cov nqi ntsuas, qhov ntsuas hluav taws xob ntsuas hluav taws xob.
Cov zis yuav tsum tsis txhob tsim ntau tshaj ib pulse.
● Kev ua haujlwm rwb thaiv tsev
Tag nrho cov kab hluav taws xob ntsuas hluav taws xob tuaj yeem tiv taus lub zog hluav taws xob nrog lub waveform ntawm 1.2 / 50μS thiab tus nqi siab tshaj ntawm 6KV ntawm lub plhaub, thiab raug sim 10 zaug tsis tu ncua nyob rau hauv cov polarities sib txawv yam tsis muaj arc tawm lossis tawg. Kev rwb thaiv tsev ntawm tag nrho cov kab hluav taws xob ntsuas hluav taws xob rau hauv av tuaj yeem tiv taus qhov hluav taws xob AC ntawm 2 KV nrog zaus ntawm 50Hz thiab qhov tseeb sinusoidal waveform, thiab qhov kev sim yuav kav ntev li ib feeb yam tsis muaj kev puas tsuaj.
● Qhov kawg ua haujlwm voltage: 80-120 feem pua Ub
● Kev siv hluav taws xob: Tsawg dua lossis sib npaug li 1W
