Iyo chikamu-chikamu chekukurumidza kudzima PLC yekudzora bhokisi chishandiso chinoshanda pamwe nechikamu-chikamu chemoto chekukurumidza kudzima actuator kugadzira iyo photovoltaic DC parutivi inokurumidza kudzima system, uye mudziyo unoenderana neAmerican National Electrical Code NEC2017&NEC2020 690.12 yekukurumidza kudzima kwe photovoltaic zviteshi zvemagetsi.Tsanangudzo inoda kuti photovoltaic system pazvivakwa zvose, uye dunhu rinopfuura 1 tsoka (305 mm) kubva kune photovoltaic module array, inofanira kudonha kusvika pasi pe30 V mukati memasekondi makumi matatu mushure mekutanga kuvhara;Dunhu mukati me 1 tsoka (305 mm) kubva kuPV module array inofanira kudonha kusvika pazasi 80V mukati memasekonzi makumi matatu mushure mekutanga kudzima.Dunhu mukati me 1 tsoka (305 mm) kubva kuPV module array inofanira kudonha kusvika pazasi 80V mukati memasekonzi makumi matatu mushure mekukurumidza kudzima.
Iyo chikamu-chikamu chemoto nekukurumidza kudzima system ine otomatiki magetsi kudzima uye kudzoreredza mabasa.Pahwaro hwekusangana nekukurumidza kuvharika basa zvinodiwa zveNEC2017&NEC2020 690.12, inogona kuwedzera kugadzirwa kwemagetsi eiyo photovoltaic simba rekugadzira system uye kugadzirisa chiyero chekugadzira magetsi.Kana iyo mains simba iri yakajairika uye pasina emergency kumira kudiwa, iyo module level fast shutdown PLC control box ichatumira murairo wekuvhara kune fast shutdown actuator kuburikidza ne photovoltaic power line kuti ubatanidze imwe neimwe photovoltaic panel;Kana magetsi emagetsi akagurwa kana kumira kwekukurumidzira kwatangwa, chikamu-chikamu chinokurumidza kuvhara PLC chekutonga bhokisi chichatumira murairo wekudimburira kune kukurumidza kuvhara actuator kuburikidza ne photovoltaic power line kuti ibvise imwe neimwe photovoltaic panel.
Chikamu-chikamu chekukurumidza kuvhara PLC kudzora bhokisi chishandiso chinoshandiswa mu photovoltaic (PV) masisitimu kufambisa nekukurumidza kuvharika kushanda pachikamu chechikamu.Kurumidza kudzima chinhu chekuchengetedza chinodiwa kudzikisa njodzi yenjodzi dzemagetsi panguva yekukurumidzira kana mabasa ekugadzirisa.
Heano mamwe mapoinzi akakosha nezve chikamu-chikamu nekukurumidza kuvhara PLC control bhokisi:
Chinangwa: Chinangwa chekutanga chechikamu-chikamu chekukurumidza kuvhara PLC chekudzora bhokisi ndechekugonesa kukurumidza kuvhara kushanda muPV system.Kurumidza kudzima kunoreva kugona kukurumidza kubvisa-simba maDC ePV system, kudzikisa voltage pasosi kusvika padanho rakachengeteka panguva yezviitiko zvekukurumidzira kana kana basa rekugadzirisa richidikanwa.
PLC (Programmable Logic Controller): A PLC komputa yedhijitari inoshandiswa kudzora uye kugadzirisa maitiro akasiyana.Mumamiriro ezvinhu ekukurumidza kuvhara kwekudzora bhokisi, PLC inoshandiswa kutarisa uye kudzora nekukurumidza kudzima kushanda kwePV system.Inogamuchira zviratidzo kubva kune ekunze zvishandiso uye inotanga nzira yekuvhara.
Kudzora Bhokisi: Bhokisi rekudzora rine inodiwa wedunhu, zvikamu, uye maratidziro kuti aite nekukurumidza kudzima kushanda.Iyo inowanzo sanganisira mapimendi ekugamuchira masaini kubva kune ekunze zvishandiso, sekukurumidza kuvharika ekutanga kana emergency shutdown switch, uye zvinobuda kudzora kudzima kwePV system.
Component-Level Shutdown: Chikamu-chikamu chekukurumidza kuvhara sisitimu inosanganisira kuvharika kwezvimwe zvikamu kana zvikamu zvePV system, pane kuvhara iyo yese system.Izvi zvinobvumira vanopindura zvechimbichimbi kana vashandi vekugadziridza kuti vashande zvakachengetedzeka munzvimbo chaidzo pasina kuratidzwa kune yakakwira voltages.
Kutevedzera Makodhi uye Mayero: Kurumidza kuvharika zvinodiwa zvinotsanangurwa mumakodhi emagetsi uye zviyero, seNational Electrical Code (NEC) muUnited States.Chikamu-chikamu chinokurumidza kuvhara PLC chekudzora bhokisi chinofanira kutevedzera iyi mirairo kuti ive nechokwadi chekuti PV system inosangana nezvinodiwa kuchengetedza zvinodiwa.
Kubatanidzwa: Iyo chikamu-chikamu chekukurumidza kuvhara PLC yekudzora bhokisi inosanganiswa mune yakazara PV system yekutonga uye yekutarisa zvivakwa.Inotaurirana nezvimwe zvikamu zvehurongwa, senge inverters kana yekutarisa masisitimu, kuronga nekukurumidza kuvhara maitiro.
Izvo zvakakosha kubvunza ane hunyanzvi hwemagetsi kana PV system dhizaini kuti ive nechokwadi chekusarudzwa kwakaringana, kuisirwa, uye kubatanidzwa kwechikamu-chikamu chekukurumidza kuvhara PLC control box.Kutevedzera makodhi emagetsi emunharaunda uye mirau inofanirwa kutevedzwa kuve nechokwadi chekuchengetedza uye kuvimbika kwePV system.
Tikugashirei kuti utibvunze kune yako yakakosha kudiwa paRapid Shutdown PLC Kudzora Bhokisi
