Cov Lus Qhia: Daim ntawv no qhia txog daim ntawv thov ntawm Acrel DJSF1352-RN DC lub zog ntsuas hluav taws xob hauv DC sab ntawm lub tshuab hluav taws xob photovoltaic hauv Nigeria. Nws yog tsuas yog siv los ntsuas DC tam sim no nyob rau hauv lub tshuab hluav taws xob photovoltaic, thiab koom tes nrog cov cuab yeej tam sim no los ntsuas, sib txuas lus thiab tswj cov kab ke hauv Circuit Court.
1. Qhov project Overview
Lub tuam txhab nyob hauv Nigeria thiab yog lub tuam txhab hluav taws xob tshiab. Feem ntau koom nrog hauv kev tsim hluav taws xob photovoltaic hauv Africa. Cov neeg siv khoom xav siv DC meters thiab cov sensors rau saib xyuas tam sim no thiab voltage ntawm DC sab ntawm photovoltaic system.
2. DJSF1352-RN DC Zog Meters
DJSF1352-RN rail-mounted DC lub zog ntsuas hluav taws xob tsim los rau kev sib txuas lus hauv paus chaw nres tsheb, DC them pawg, hnub ci photovoltaic thiab lwm yam kev siv, cov ntsuas ntsuas no tuaj yeem ntsuas qhov voltage, tam sim no, lub zog thiab rov qab thiab rov qab zog thiab lwm yam hauv DC system. Kev siv qhov chaw tiag tiag, koj tuaj yeem ntsuas tag nrho lub zog, tab sis kuj ntsuas lub zog hauv lub sijhawm teev tseg. Cov txiaj ntsig kev xeem tuaj yeem siv rau cov khoom siv hauv zos, tab sis kuj nrog cov cuab yeej tswj kev lag luam, khoos phis tawj los tsim kev ntsuas thiab kev tswj hwm.
Lub 'meter' tuaj yeem muaj kev sib txuas lus infrared thiab RS-485 kev sib txuas lus interface, thiab txhawb Modbus-RTU raws tu qauv thiab DLT645-97 (07) raws tu qauv tib lub sij hawm.Lub 'meter' yuav muaj relay tswb tso zis thiab cov input muaj nuj nqi; Koj muaj peev xwm teem lub ratio. , tswb, thiab kev sib txuas lus los ntawm cov 'meter' vaj huam sib luag yuam sij raws li cov kev xav tau sib txawv.The 'meter' tuaj yeem muaj qhov xwm txheej kaw ntawm kev hloov pauv (Modbus raws tu qauv), programming thiab teeb tsa cov ntaub ntawv (645 raws tu qauv), instantaneous thiab lub sij hawm khov muaj nuj nqi ntawm cov ntaub ntawv (645 raws tu qauv), qhov siab tshaj plaws thiab qhov tsawg kawg nkaus tus nqi sau ua haujlwm ntawm qhov hluav taws xob thiab lub zog tam sim no.
3. Hom thiab Function Description
Nco tseg: thaum xaiv dual DC input (D) muaj nuj nqi, yog Hall tam sim no sensor input siv nyob rau hauv
tam sim no channel, ib lub hwj huam mov module yuav tsum muab lub hwj chim rau lub thib ob Hall sensor; yog hais tias D muaj nuj nqi tsis muab, lub built-in fais fab mov ntawm hluav taws xob meter yuav siv tau.
