I-MFR 300 iyi-transducer yokulinganisa yokuqapha izinhlelo zamandla zesigaba esisodwa nesesithathu. I-MFR 300 inakho kokubili okokufaka kwamandla kagesi kanye namanje okukala umthombo wamandla kagesi. Iphrosesa yedijithali yenza kube nokwenzeka ukukala ngokunembile amanani eqiniso e-RMS, kungakhathaliseki ukuthi ama-harmonics, ama-transients noma ama-pulses aphazamisayo. Amanani ayisisekelo alinganisiwe nabaliwe adluliselwa ngephrothokholi ye-CANopen / Modbus kusistimu yokulawula yokugada.
I-MFR 300 yenza imisebenzi yokuqapha yokunqanyulwa kwamapayipi amakhulu, okuhlanganisa imisebenzi emine elungiseka ngokukhululekile encike ngesikhathi ye-FRT (i-fault rithrough). Amanani alinganisiwe ayinhloko we-voltage ne-current asetshenziselwa ukubala amandla wangempela, asebenzayo, namandla abonakalayo kanye namanani esici samandla (cosphi)
Uhlu lwamanani alinganisiwe luhlanganisa • Measured o Voltage Wye: VL1N / VL2N / VL3N Delta: VL12 / VL23 / VL31 o Frequency fL123 o Yamanje IL1/IL2/IL3 • Kubalwe o Isilinganiso sikagesi VØL123 yamanje / I-Vmax IØ123 yamanje / I-Vmin oLve Imax o Amandla wangempela Ptotal / PL1 / PL2 / PL3 o Amandla asebenzayo Qtotal o Amandla abonakalayo Stotal o Power factor (cosφL1) o Amandla asebenzayo kWhpositive/negative o Amandla asebenzayo kvarhleading/lagging
Izici • Okokufaka kwe-voltage yangempela ye-RMS oku-3 • Okokufaka kwamanje kwe-RMS okuyiqiniso oku-3 • Ukunemba kwesigaba 0.5 sevoltheji, imvamisa kanye namandla • Ukunemba kweSigaba 1 samandla wangempela noma asebenzayo noma amandla • Amasethingi ohambo/okulawula alungisekayo • Izibali-sikhathi zokulibaziseka ezilungisekayo zama-alamu angawodwana (0.02 kuya ku-300.00 s) • Ukuhlelwa kabusha kokusebenza oku-4 i-relay • I-relay logic eshintshwayo • izinto zokubala ezingu-2 kWh (ubukhulu 1012 kWh) • 2 kvarh wokubala (ubukhulu 1012 kvarh) • Ukuxhumana kwe-CANopen / Modbus • Kulungiseka ngebhasi le-CAN / RS-485 / Imbobo yesevisi (USB/RS-232) • ugesi ongu-24 Vdc
Ukuvikelwa (konke) ANSI # • Over-/undervoltage (59/27) • Over-/underfrequency (81O/U) • Voltage asymmetry (47) • Overload (32) • Positive/negative load (32R/F) • Umthwalo ongabhalansi (46) • Phase shift/Overcurrent1/dt (78) (ROCOF) • Iphutha eliphansi • Ukuqapha kwe-QV • Ukwenyuka kwamandla kagesi • Ukuqapha ngokukhululekile okuncike esikhathini okuncike ku-undervoltage kwe: o FRT (ukugibela iphutha)
