CNC | Ibhokisi lokulawula ukuvala okusheshayo kwe-PLC

Ibhokisi lokulawula elisheshayo le-Complent-Level Support liyithuluzi elisebenzisana ne-Complent-Level Fire Shutch Shutdown System ukwakha i-American National Shutdown System NEC2017 & NEC2020 Ukuvalwa okusheshayo kweziteshi zikagesi ze-Photovoltaic. Ukucaciswa kudinga ukuthi uhlelo lwe-Photovoltaic kuzo zonke izakhiwo, kanye nesifunda esingaphezu kwe-1 unyawo (305 mm) kusuka ku-Photovoltaic module Array, kufanele kwehle ngaphansi kwama-30 v kungakapheli imizuzwana engama-30 ngemuva kokuqala kokuvalwa okusheshayo; Umjikelezo ngaphakathi kwe-1 Foot (305 mm) kusuka ku-PV Module Array kumele alahle ngaphansi kwe-80V kungakapheli imizuzwana engama-30 ngemuva kokuqala kokuvalwa okusheshayo. Umjikelezo ongena ngaphansi kwe-1 unyawo (305 mm) kusuka kuhlu lwemodyuli ye-PV kumele ahlele ngaphansi kwama-80v kungakapheli imizuzwana engama-30 ngemuva kokuqala kokuvalwa okusheshayo.
Uhlelo lokuvala okusheshayo kwengxenye ye-Compenent-Level Fire REAST lunamandla okuzenzakalelayo futhi kubuye kabusha imisebenzi. Ngokwesisekelo sokuhlangabezana nezidingo ezisheshayo zokuvala umsebenzi we-NEC2017 ne-NEC2020 690.12, zingandisa isizukulwane samandla sohlelo lokuphehla lwamandla we-Photovoltaic futhi sithuthukise izinga lokuphehla amandla. When the mains power is normal and there is no emergency stop demand, the module level fast shutdown PLC control box will send a closing command to the fast shutdown actuator through the photovoltaic power line to connect each photovoltaic panel; Lapho amandla e-mains enqunywa noma ukumiswa okuphuthumayo kuqalwa, ibhokisi lokulawula elisheshayo le-Complent-Level Suppoll lizothumela umyalo wokunqamula kwi-actuator esheshayo yokuvala ngokushesha ngomugqa wamandla we-Photovoltaic ukunqamula iphaneli ngayinye ye-Photovoltaic ukunqamula iphaneli ngayinye ye-Photovoltaic ukunqamula iphaneli ngayinye ye-Photovoltaic ukunqamula iphaneli ngayinye ye-Photovoltaic ukunqamula.

Ibhokisi lokulawula elisheshayo le-Complent-Level Suppoll liyidivayisi esetshenziswa ezinhlelweni ze-Photovoltaic (PV) ukwenza lula ukusebenza okusheshayo okusheshayo ezingeni lengxenye. Ukuvalwa okusheshayo kuyimfuneko yokuphepha okuhloswe ngayo ukunciphisa ubungozi bezingozi zikagesi ezimweni eziphuthumayo noma imisebenzi yokulungisa.

Nawa amanye amaphuzu asemqoka mayelana nebhokisi lokulawula elisheshayo le-PLC:

INJONGO: Injongo eyinhloko yebhokisi lokulawula elisheshayo le-Contron-Level Shutch ukunika amandla ukusebenza okusheshayo okusheshayo ohlelweni lwe-PV. Ukuvalwa okusheshayo kubhekisele emandleni okusheshisa ngokushesha amasekethe we-DC wohlelo lwe-PV, kunciphisa i-voltage emthonjeni oya emthonjeni ophephile ngesikhathi semicimbi ephuthumayo noma lapho kudingeka umsebenzi wesondlo.

I-PLC (Isilawuli Esihlekisayo se-Plagramff): I-PLC iyikhompyutha yedijithali esetshenziselwa ukulawula nokushintsha izinqubo ezahlukahlukene. Ngokwesimo sebhokisi lokulawula elisheshayo elisheshayo, i-PLC isetshenziselwa ukuqapha nokulawula ukusebenza okusheshayo kokuvalwa kohlelo lwe-PV. Ithola amasiginali avela kumadivayisi angaphandle futhi iqala inqubo yokuvala.

Ibhokisi Lokulawula: Ibhokisi lokulawula liqukethe ukujikeleza okudingekayo, izakhi, kanye nokuxhumana nokusebenzisa ukusebenza okusheshayo okusheshayo. Imvamisa ifaka okokufaka okuthola amasiginali kusuka kumadivayisi angaphandle, njengama-rapid shutha kuqala ama-transchers noma ukushintshwa okushintshiwe okuphuthumayo, nokuphuma kokulawula ukuvalwa kohlelo lwe-PV.

Ukuvalwa kwezinga le-Condonent Lokhu kuvumela abaphenduli bezimo eziphuthumayo noma abasebenzi bokugcina basebenze ngokuphepha ezindaweni ezithile ngaphandle kokuvezwa ngama-voltages aphezulu.

Ukuhambisana namakhodi namazinga: Izidingo zokuvala ngokushesha zichaziwe kumakhodi kagesi namazinga, njengekhodi kagesi kazwelonke (i-NEC) e-United States. Ibhokisi lokulawula elisheshayo le-Contrent-Level Support kufanele lihambisane nale mithethonqubo ukuqinisekisa ukuthi uhlelo lwe-PV luhlangabezana nezidingo zokuphepha ezidingekayo.

Ukuhlanganiswa: Ibhokisi lokulawula elisheshayo le-Complent-Level Suppondos lihlanganiswe nokulawulwa kohlelo lwe-PV jikelele kanye nokuqapha kwengqalasizinda. Ixhumana nezinye izinto zohlelo, njengama-inverterers noma amasistimu wokuqapha, ukuxhumanisa inqubo esheshayo yokuvala.

Kubalulekile ukuthintana noMklami Wezomsebenzi kagesi noma we-PV ukuqinisekisa ukukhethwa okufanele, ukufakwa, kanye nokuhlanganiswa kwebhokisi lokulawula elisheshayo le-PLC. Ukuhambisana namakhodi kagesi endawo kanye nemigomo kufanele kulandelwe ukuqinisekisa ukuphepha nokwethenjwa kohlelo lwe-PV.
Uyemukelwa ukuze sibhekane nathi ngesidingo sakho esikhethekile ebhokisini lokulawula i-RAPER SURSDOWNL
