I-IEC 60364-7-712: 2017

Ufakelo lombane ombane ophantsi-Icandelo 7-712: Iimfuno zofakelo olukhethekileyo okanye indawo-Iinkqubo zonikezelo lwamandla eSolar photovoltaic (PV)

IKhomishini ye-Electrotechnical International (IEC) ikhuphe i-IEC 60364-7-712: 2017 ye “Low voltage installation - Part 7-712: Iimfuno zofakelo olukhethekileyo okanye iindawo - Solar photovoltaic (PV) systems systems”.

Inkcazo: "I-IEC 60364-7-712: 2017 isebenza kufakelo lombane kwiinkqubo zePV ezijoliswe ukubonelela yonke okanye inxalenye yofakelo. Izixhobo zofakelo lwe-PV, njengayo nayiphi na into eyenye yezixhobo, kujongwana nayo kuphela ngokokuchongwa kwayo kunye nokusetyenziswa kofakelo. Olu shicilelo lutsha lubandakanya uhlaziyo olubalulekileyo kunye nolwandiso, kuthathelwa ingqalelo amava afunyenwe kulwakhiwo kunye nokusebenza kofakelo lwePV, kunye nophuhliso lwetekhnoloji, okoko kwapapashwa uhlelo lokuqala lwalo mgangatho.

Ububanzi:

Eli candelo le-IEC 60364 lisebenza kufakelo lombane lweenkqubo ze-PV ezijolise ekunikezeleni konke okanye inxenye yofakelo.

Izixhobo zofakelo lwe-PV, njengayo nayiphi na into eyenye yezixhobo, kujongwana nayo kuphela ngokokuchongwa kwayo kunye nokusetyenziswa kofakelo.

Ufakelo lwe-PV luqala kwimodyuli ye-PV okanye iseti yeemodyuli ze-PV ezixhumeke kuthotho kunye neentambo zazo, ezibonelelwa ngumenzi wemodyuli ye-PV, ukuya kufakelo lomsebenzisi okanye indawo yonikezelo losetyenziso (inqaku lokudibanisa okuqhelekileyo).

Iimfuno zolu xwebhu ziyasebenza

• Ufakelo lwe-PV olungadibenanga nenkqubo yokuhambisa umbane kuluntu,
• Ufakelo lwe-PV ngokuhambelana nenkqubo yokuhambisa umbane kuluntu,
• Ukufakwa kwe-PV njengenye indlela yokuhambisa umbane kuluntu,
• indibaniselwano efanelekileyo kwezi zingasentla. Olu xwebhu alubandakanyi iimfuno ezithile zokufakelwa kweebhetri okanye ezinye iindlela zokugcina amandla.

QAPHELA 1 Iimfuno ezongezelelweyo zofakelo lwe-PV ezinamandla okugcina ibhetri kwicala le-DC ziyaqwalaselwa.

QAPHELA 2 Olu xwebhu lugubungela iimfuno zokhuselo lwee-PV ezikhulayo ngenxa yokusetyenziswa kweebhetri kufakelo lwe-PV.

Kwiinkqubo ezisebenzisa i-DC-DC converters, iimfuno ezongezelelweyo ngokubhekisele kumandla ombane kunye nenqanaba langoku, ukutshintshela, kunye nezixhobo zokukhusela zinokufaka Ezi mfuno ziqwalaselwa.

Injongo yolu xwebhu kukujongana neemfuno zokhuseleko zoyilo ezivela kwiimpawu ezithile zokufakwa kwePV. Iinkqubo zeDC, kunye noluhlu lwe-PV ngokukodwa, zibeka ezinye iingozi ukongeza kwezo zithathwa kufakelo lwamandla oluqhelekileyo lwe-AC, kubandakanya nokukwazi ukuvelisa kunye nokugcina iiarcs zombane ngemisinga engekho mikhulu kunendlela yokusebenza yesiqhelo.

Kufakelo lwe-PV oluhlanganisiweyo iimfuno zokhuselo zolu xwebhu, nangona kunjalo, zixhomekeke kakhulu kwi-PCE ehambelana nolungelelwaniso lwe-PV ngokuhambelana neemfuno ze-IEC 62109-1 kunye ne-IEC 62109-2.
