Amaphrojekthi we-Acrel
I-ACREL DJSF1352-RN DC amamitha wamandla Isicelo kusistimu yemitha ye-UPS eRussia
Abstract:Lesi sihloko sethula ukusetshenziswa kwemitha ye-“Acrel” DJSF1352-RN DC ohlelweni lwemitha ye-UPS yaseRussia. Inzwa yehholo.
1. Uhlolojikelele lwephrojekthi
Le nkampani iseRussia futhi iyinkampani ekhiqiza amabhethri.Ikakhulukazi ibambe iqhaza ekukhiqizeni nasekuhlinzekeni amabhethri ezimboni kanye ne-UPS eRussia.Ikhasimende lidinga ukusebenzisa imitha ye-DC ukuqapha nokulinganisa amandla kagesi ekuphumeni kwe-UPS.
2.DJSF1352-RN DC Energy Meters
Imitha yamandla kagesi ye-DJSF1352-RN efakwe ujantshi we-DC eyenzelwe iziteshi eziyisisekelo zokuxhumana, inqwaba yokushaja ye-DC, i-solar photovoltaic nezinye izinhlelo zokusebenza, lolu chungechunge lwamamitha lungakwazi ukukala i-voltage, yamanje, amandla okuya phambili nokuhlehlisa njalonjalo ohlelweni lwe-DC. Ukusetshenziswa langempela isayithi, ungakwazi ukukala amandla ingqikithi, kodwa futhi ukukala amandla phakathi nenkathi ethile yesikhathi. Imiphumela yokuhlolwa ingasetshenziselwa ukuboniswa kwendawo, kodwa futhi nemishini yokulawula yezimboni, amakhompyutha ukwenza isistimu yokulinganisa nokulawula.
Imitha ingaba ne-infrared communication interface kanye ne-RS-485 ukuxhumana nokuxhumana, futhi isekela umthetho olandelwayo we-Modbus-RTU kanye nephrothokholi ye-DLT645-97 (07) ngesikhathi esifanayo. , i-alamu, nokuxhumana ngokhiye bephaneli yemitha ngokwezidingo ezahlukene.Imitha ingaba nokuqoshwa komcimbi we-switch (i-Modbus protocol), amarekhodi okuhlelwa kwezinhlelo kanye nomcimbi (i-protocol ye-645), umsebenzi wokumisa ngokushesha kanye nesikhathi sokumisa idatha (i-protocol engu-645), umsebenzi wokuqopha inani eliphakeme nelincane le-voltage namandla amanje.
3.Uhlobo kanye Nencazelo Yomsebenzi
Qaphela:lapho okokufaka okubili kwe-DC (D) kukhethwa, uma okokufaka kwenzwa yamanje yeHholo kusetshenziswa kusiteshi samanje, imojula yokuphakelwa kwamandla izohlinzekwa ukuze kunikezwe amandla kunzwa yesibili yeHholo; uma umsebenzi we-D unganikeziwe, ukunikezwa kwamandla okwakhelwe ngaphakathi kwemitha kagesi kungasetshenziswa.

4.Izimfuneko Zekhasimende
Ikhasimende lifuna ukulinganisa amandla angempela okukhiphayo e-UPS ukuze libale isilinganiso sokuguqulwa sesitoreji samandla se-UPS ekusetshenzisweni kwamandla. Isiphetho sokufakwayo kwe-UPS sisebenzisa imitha yethu kagesi yochungechunge lwe-ADL, isiphetho esiphumayo sisebenzisa imitha ye-DJSF1352-RN DC, futhi isignali kagesi ithathwa nge-shunt inorder ukuze kuzuzwe injongo yokulinganisa okukhiphayo.
