ACREL DJSF1352-RN DC simba mita Kushandisa muUPS metering system muRussia
Abstract:Ichi chinyorwa chinosuma mashandisirwo e "Acrel" DJSF1352-RN DC mita muRussia UPS metering system.Inonyanya kushandiswa kuyerwa kwesimba rinobuda muUPS system, uye kuyerwa, kutaurirana uye kutonga kwedunhu system kuburikidza ne Horo sensor.
1.Project Overview
Iyo kambani iri muRussia uye ikambani yekugadzira bhatiri.Inonyanya kubatanidzwa mukugadzirwa uye kugovera mabhatiri emabhizimisi uye UPS muRussia.Mutengi anoda kushandisa DC mita yekuongorora uye kuyera simba remagetsi pakubuda kweUPS.
2.DJSF1352-RN DC Energy Meters
DJSF1352-RN rail-mounted DC power meter yakagadzirirwa nhepfenyuro dzenhare, DC yekuchaja mirwi, solar photovoltaic uye mamwe maapplication, iyi nhevedzano yemamita inogona kuyera voltage, ikozvino, simba uye kumberi nekudzosera kumashure simba uye zvichingodaro muDC system. Iko kushandiswa chaiko kwesaiti, unogona kuyera simba rose, asiwo kuyera simba mukati menguva yakatarwa yenguva. Mhedzisiro yebvunzo inogona kushandiswa kuratidzwa kwenzvimbo, asiwo neindasitiri yekudzora michina, makomputa kugadzira kuyerwa uye kutonga system.
Iyo mita inogona kunge ine infrared communication interface uye RS-485 yekutaurirana interface, uye inotsigira Modbus-RTU protocol uye DLT645-97 (07) protocol panguva imwe chete. Iyo mita inogona kuva nerelay alarm yekubuda uye digital input function; Unogona kuseta reshiyo. , alarm, uye kutaurirana kuburikidza nemamita mapaneru makiyi maererano nezvinodiwa zvakasiyana-siyana.Meta inogona kuva nechiitiko chekurekodha chekuchinja (Modbus protocol), purogiramu uye chiitiko chekuisa zvinyorwa (645 protocol), pakarepo uye nguva yekumisa basa re data (645 protocol), hukuru uye hushoma kukosha kwekurekodha basa remagetsi uye ikozvino simba.
3.Type uye Basa Rondedzero
Ongorora: kana mbiri mbiri DC inopinza (D) basa rakasarudzwa, kana Horo yazvino sensor yekuisa ichishandiswa muchiteshi chazvino, magetsi emagetsi module achapihwa kupa simba kune yechipiri Horo sensor; kana D basa risina kupihwa, iyo yakavakirwa-mukati magetsi emagetsi mita inogona kushandiswa.

4.Mutengi Zvinodiwa
Mutengi anoda kuyera iro chairo rinobuda simba reUPS kuverenga chiyero chekushandura cheUPS chekuchengetedza simba kune simba rekushandisa. Iyo UPS yekuisa yekupedzisira inoshandisa yedu ADL yakatevedzana yemagetsi mita, iyo inobuda inopera inoshandisa DJSF1352-RN DC mita, uye chiratidzo chemagetsi chinotorwa kuburikidza neshunt inorder kuzadzisa chinangwa chekuyerwa kwekubuda.
