Bokosi loyang'anira lotsekera mwachangu la PLC ndi chipangizo chomwe chimagwirizana ndi cholumikizira chamoto chozimitsa mwachangu kuti apange photovoltaic DC mbali yotseka mwachangu, ndipo chipangizocho chimagwirizana ndi American National Electrical Code NEC2017&NEC2020 690.12 kuti atseke mwachangu ma photovoltaic malo opangira magetsi.Kufotokozera kumafuna kuti photovoltaic system pa nyumba zonse, ndi dera lopitirira 1 phazi (305 mm) kuchokera ku photovoltaic module array, liyenera kutsika mpaka pansi pa 30 V mkati mwa masekondi a 30 pambuyo poyambira mofulumira;Dera mkati mwa phazi limodzi (305 mm) kuchokera pagawo la PV module liyenera kutsika mpaka pansi pa 80V mkati mwa masekondi 30 mutangoyamba kutseka mwachangu.Dera mkati mwa phazi limodzi (305 mm) kuchokera pagawo la PV module liyenera kutsika mpaka pansi pa 80V mkati mwa masekondi 30 kutseka kofulumira kuyambika.
Dongosolo lozimitsa moto lomwe lili ndi gawo lazigawo lili ndi mphamvu yozimitsa yokha ndikutsekanso ntchito.Pamaziko okwaniritsa zofunikira zotsekera mwachangu za NEC2017&NEC2020 690.12, zitha kukulitsa kutulutsa mphamvu kwamagetsi amagetsi a photovoltaic ndikuwongolera kuchuluka kwamagetsi.Pamene mphamvu ya mains ndi yachibadwa ndipo palibe kufunikira kwadzidzidzi kwadzidzidzi, mlingo wa module fast shutdown PLC control box udzatumiza lamulo lotsekera ku shutdown actuator yofulumira kupyolera mu mzere wa mphamvu ya photovoltaic kuti mugwirizane ndi gulu lililonse la photovoltaic;Mphamvu ya mains ikadulidwa kapena kuyimitsidwa kwadzidzidzi kuyambika, bokosi loyang'anira gawo lotsekera mwachangu la PLC lidzatumiza lamulo loletsa kutsekera mwachangu kudzera pa chingwe chamagetsi cha photovoltaic kuti muchotse gulu lililonse la photovoltaic.
Bokosi lowongolera la PLC ndi chipangizo chomwe chimagwiritsidwa ntchito pamakina a photovoltaic (PV) kuti athandizire kutseka kwachangu pamlingo wagawo.Kuyimitsa mwachangu ndi chofunikira pachitetezo chomwe cholinga chake ndi kuchepetsa chiwopsezo chamagetsi panthawi yadzidzidzi kapena kukonza.
Nawa mfundo zazikuluzikulu za bokosi lowongolera la PLC lazigawo zagawo:
Cholinga: Cholinga chachikulu cha bokosi lowongolera la PLC lotsekera mwachangu ndikuthandizira kutseka kwachangu mudongosolo la PV.Kuyimitsa mwachangu kumatanthauza kutha kutulutsa mphamvu mwachangu mabwalo a DC a PV system, kuchepetsa mphamvu yamagetsi pagwero kuti ikhale yotetezeka pakachitika ngozi kapena pakafunika kukonza.
PLC (Programmable Logic Controller): A PLC ndi kompyuta ya digito yomwe imagwiritsidwa ntchito kuwongolera ndikusintha njira zosiyanasiyana.Pankhani ya bokosi lowongolera mwachangu, PLC imagwiritsidwa ntchito kuwunika ndikuwongolera magwiridwe antchito a PV system.Imalandira zizindikiro kuchokera ku zipangizo zakunja ndikuyambitsa ndondomeko yotseka.
Bokosi Loyang'anira: Bokosi lowongolera lili ndi zozungulira zofunika, zigawo, ndi ma interfaces kuti akwaniritse ntchito yotseka mwachangu.Nthawi zambiri imaphatikizapo zolowa zolandirira ma siginecha kuchokera ku zida zakunja, monga zoyambitsa kuzimitsa mwachangu kapena zosinthira mwadzidzidzi, ndi zotuluka kuti ziwongolere kuzimitsa kwa dongosolo la PV.
Kutsekera kwa Gawo la Gawo: Dongosolo lotsekera mwachangu limaphatikizapo kutseka kwa magawo kapena magawo ena a dongosolo la PV, m'malo motseka dongosolo lonse.Izi zimathandiza ogwira ntchito zadzidzidzi kapena ogwira ntchito yokonza kuti azigwira ntchito motetezeka kumadera enaake popanda kukumana ndi ma voltages apamwamba.
Kutsata Ma Code ndi Miyezo: Zofunika kuzimitsa mwachangu zimafotokozedwa m'makhodi amagetsi ndi miyezo, monga National Electrical Code (NEC) ku United States.Bokosi loyang'anira lotsekera mwachangu la PLC liyenera kutsatira malamulowa kuwonetsetsa kuti dongosolo la PV likukwaniritsa zofunikira zachitetezo.
Kuphatikizika: Bokosi loyang'anira lotsekera mwachangu la PLC limaphatikizidwa ndikuwongolera ndikuwunika kwa dongosolo lonse la PV.Imalumikizana ndi zigawo zina zamakina, monga ma inverters kapena makina owunikira, kuti agwirizane ndi kutsekeka kofulumira.
Ndikofunikira kulumikizana ndi katswiri wodziwa zamagetsi kapena wopanga makina a PV kuti muwonetsetse kusankha koyenera, kuyika, ndi kuphatikiza bokosi lowongolera la PLC lotsekera.Kutsatira malamulo amagetsi am'deralo kuyenera kutsatiridwa kuti zitsimikizire chitetezo ndi kudalirika kwa dongosolo la PV.
Takulandilani kuti mutiuze za zomwe mukufuna pa Rapid Shutdown PLC Control Box
