Imishini yokuhlola ezenzakalelayo yesigaba sesithathu yemitha yamandla

1, Imiklamo eminingi yesakhiwo, ucezu olulodwa noma uhlaka oluhlukanisiwe; uhlaka olukhethekile lwe-aluminium alloy, phezulu kwetafula lezinto ezingashi, ukubukeka okuhle nokuphanayo.

I-2, Ihambisana ne-smart meter standard yenethiwekhi kazwelonke yokuminyanisa uhlobo lwebhokisi (amatheminali ama-4 amakhulu amanje, amatheminali amasignali amancane ayi-8), indawo yemitha ngayinye enomsebenzi wokutholwa kwesekethe evulekile, umsebenzi wesikhundla semitha esingenalutho ongawukhetha.

I-3, idizayini ye-loop yamanje ekabili, indawo ngayinye yemitha ifakwe ama-relay amabili okugcina kazibuthe angu-100A aphezulu; ingenza iphutha elizenzakalelayo le-loop eliyinhloko nelesibilitestukuze kunqandwe ukuntshontsha imitha yamandla ekabili; ukusekela ukulinganisa okwenziwa ngesandla kanye nokuzenzakalelayo kwemitha ye-State Grid yesigaba esisodwa semali ephindwe kabili yesifunda-elawulwa yimitha yamandla ehlakaniphile; asikho isidingo sokuxhumeka kwesibili kwemitha, ngokushintshwa kwe-relay ukuze kuzuzwe isifunda se-firewire (L) kanye nesekhethi ye-zero-wire (N) yesifunda se-firewire (L) kanye ne-zero-wire (N) ngaphandle kokuhlukanisa ukuhlolwa, okuqedwe ngesikhathi esisodwa; amasekhethi amabili amanje angaxhunywa ngekhiphedi enomsebenzi wokuthola isekethe evulekile, ngokushoda okuzenzakalelayo okuzenzakalelayo kwamamitha angenamuntu. Kuqediwe; amasekhethi amabili amanje angashintshwa ngekhibhodi noma ashintshwe ngokuzenzakalelayo ngesofthiwe yokulinganisa;

4. Ukwamukela umthombo wamandla othuthukisiwe we-digital pulse width modulation, i-voltage ephumayo (yamanje) isebenza kahle kakhulu, ikhiqiza ukushisa okuphansi nokuzinza okuphezulu, okungaxazulula ngokuphelele inkinga yokuhlukahluka okukhulu kwamandla amancane.

I-5, ukutholwa kwamaphutha okuphelele, ukwenziwa kwasendaweni, ukuvikela kanye nemisebenzi ye-alamu, ne-voltage short circuit, i-open circuit yamanje, i-amplifier overheating, ukuthintana kabi neminye imisebenzi yokuvikela.

I-6, 2 ~ 21th harmonic superposition, amplitude kanye nesigaba singasethwa ngokukhululekile (i-harmonic amplitude ngaphakathi kwe-40% yegagasi eliyisisekelo, isigaba 0～360.). Ingakwazi futhi ukuhlaziya ama-harmonics okukhiphayo futhi idwebe ama-waveforms; ingakwazitestithonya le-harmonic kumitha yamandla.

I-7, imitha ngayinye ifakwe okokufaka kwe-pulse okuzimele okunomsebenzi wokuvikela we-voltage ephezulu, okokufaka kwesignali esebenzayo, isixhumi esibonakalayo sesignali yezokuxhumana engu-485, kanye nebhodi lokubonisa elisebenzayo eline-6-bit digital display (ukubonisa iphutha eliyisisekelo, inombolo yama-pulses ehambayo, iwashi lemitha, izimpawu zesimo ezihlukahlukene, njll.).

8, uhlelo lokuhlola lungasethwa ngendlela eguquguqukayo, lungaqedela iphutha eliyisisekelo, ukulinganisa okungaguquki, isivivinyo sokuqala esingaba khona, amandla anesilinganiso esiningi, i-voltage, yamanje, isici samandla, iphutha lamanje likalayini we-zero, njll., iphutha lesikhathi sansuku zonke, isikhathi sephutha lokukhipha nokusika, isidingo sephutha lenani, isidingo sesikhathi sephutha, nokunye, zonke izidingo zokunemba zokuhlolwa.

9, ingaqedela ukuhluka kwephutha, ukungaguquguquki kwephutha, ukukhuphuka kwamanje nokwehluka kokulayisha, ukugcwala kwamanje nokunye ukuhlolwa kokuvumelana kanye nokuhlolwa komthelela okuhlukahlukene.

I-10, Ingakwazi ukuhlola ithonya le-voltage, ithonya lemvamisa, ithonya le-harmonic namanye amathonya kuzo zonke izinhlobo zamamitha wamandla.

11, Ingakwazi ukubona isikhathi esinembile semitha yamandla ngokusebenzisa imojuli ye-GPS enembayo.

Ingenza ukuhlolwa kokuxhumana, ukulinganisa isikhathi sokusakaza, ukuqinisekiswa kwedatha yangaphakathi, ukuhlolwa kwesikhathi sendawo yesikhathi kanye nokuhlolwa kwephutha lenhlanganisela lamamitha kagesi emisebenzi eminingi kanye namamitha kagesi anezilinganiso eziningi.

11 Isekela ukunemba kokuncipha kwamandla, ukuhlolwa kokushintsha intela, ukugingqika kokushintsha komthwalo kanye nokuhlola kokuvala (ukudonsa okwamanje kwe-relay low-voltage eyakhelwe ngaphakathi, ukutholwa kwamandla kagesi adluliselwe ngaphandle kwe-AC220) nokunye ukuhlola umsebenzi wokulawula imali.

13 Ingavivinya umsebenzi wokuqandisa wemitha ehlakaniphile, futhi ingenza izivivinyo zezindlela ezihlukahlukene zokuqandisa.

I-14 ingahlola umsebenzi wokuqopha umcimbi wemitha ehlakaniphile, okuhlanganisa ukulahlekelwa kwamandla kagesi, ukulahleka kwamandla amanje, ikhefu lesigaba, ukulahlekelwa okuphelele kwamandla kagesi, ukwehla kwamandla, ukuhlela, ukususa u-zero, ikhava yokushintsha, isango elidonsayo, njll.

I-15 ingahlola ukwehla kwamandla kagesi kanye nokuphazamiseka kwamandla, amandla akhuphuka kancane futhi awe, njll.

I-16, Ingahlola isibonisi sokuhluleka kwamandla kanye nomsebenzi wokufunda wamamitha wokuhluleka kwamandla wemitha ehlakaniphile.

17, ukusetshenziswa kwe-serial port iseva noma multi-channel 485 zokuxhumana ukuguqulwa ibhodi, eziphambili multi-threading software ubuchwepheshe, ukuze multi-imitha 485 ukuxhumana parallel, ngcono kakhulu ukusebenza kahle kokuxhumana.

18, Isishintshi semojula yenkampani yenethiwekhi ozikhethela ukuthola ukuhlolwa kokuxhumana kwenkampani yenethiwekhi yemitha yamandla yesigaba esisodwa.

19, umsebenzi wokuthola okukhokhelwayo - ukuhlolwa komsebenzi wohambo; ukucushwa kwedivayisi kweluphu yesithathu yamanje; ingahlola ukunemba kokuncipha kwamandla ayinsalela akhokhelwa kusengaphambili, ifake ikhadi lokuhlola i-relay (noma ifinyelele amandla e-alamu), ihlole imitha yamandla ngokukhubeka noma ngaphandle kokukhubeka. Ekuhlolweni kokusebenza kokuhamba kwemitha yekhadi elikhokhelwa ngaphambilini, ku-voltage nokukhuphuka kwamanje, isifunda samanje sanoma iyiphi indawo yemitha sinqanyuliwe, i-voltage kanye ne-current yedivayisi ingaqinisekisa ukuphuma okujwayelekile, i-current is not open circuit, ayikho i-alamu nokuvala shaqa, akukho mthelela ekusebenzeni kwamanye amamitha, futhi wonke amamitha aqeda ukuhlola ngesikhathi esisodwa.

20, isofthiwe enamandla yokulawula ukulawula kwe-PC, ngokwezidingo zenethiwekhi kazwelonke ingaba nemingcele engaba ngu-2000 yokufunda nokubhala idatha, isikhombimsebenzisi silula futhi sicacile, imodi yehluzo yemenyu egcwele, kulula ukuyifunda nokusebenzisa. Umbuzo wesizindalwazi, izibalo, ukuphrinta, ukunethiwekha konke endaweni eyodwa.

21, Ukucushwa kwe-SG186 networking interface module

22, Nikeza imininingwane egciniwe eguquguqukayo yokuthuthukiswa kwesibili okuvela eceleni.
