I-IEC 60364-7-712: 2017

Ukufakwa kwamandla kagesi kagesi aphansi - Ingxenye 7-712: Izidingo zokufakwa noma izindawo ezikhethekile - Izinhlelo zokuhambisa ugesi zeSolar photovoltaic (PV)

I-International Electrotechnical Commission (IEC) ikhiphe i-IEC 60364-7-712: 2017 "Yokufakwa kwamandla kagesi aphansi - Ingxenye 7-712: Izidingo zokufakwa noma izindawo ezikhethekile - Izinhlelo zokuphakelwa kukagesi zeSolar photovoltaic (PV)".

Incazelo: “IEC 60364-7-712: 2017 isebenza ekufakweni kukagesi kwezinhlelo ze-PV okuhloswe ngazo ukufaka konke noma ingxenye yokufakwa. Okokusebenza kokufakwa kwe-PV, njenganoma iyiphi enye into yemishini, kubhekwana nakho kuze kube manje uma kukhethwa nokusetshenziswa kokufakwa. Lolu hlobo olusha lubandakanya izibuyekezo ezibalulekile nezandiso, kubhekelwa ulwazi olutholwe ekwakhiweni nasekusebenzeni kokufakwa kwe-PV, nentuthuko eyenziwe kubuchwepheshe, selokhu kwanyatheliswa uhlelo lokuqala lwaleli zinga. ”

Ububanzi:

Le ngxenye ye-IEC 60364 isebenza ekufakweni kukagesi kwezinhlelo ze-PV okuhloswe ngazo ukufaka konke noma ingxenye yokufakwa.

Okokusebenza kokufakwa kwe-PV, njenganoma iyiphi enye into yemishini, kubhekwana nakho kuze kube manje uma kukhethwa nokusetshenziswa kokufakwa.

Ukufakwa kwe-PV kuqala kusuka kumodyuli ye-PV noma iqoqo lamamojula we-PV axhunywe ochungechungeni nezintambo zawo, ezinikezwe ngumenzi wemodyuli ye-PV, kuze kufike ekufakweni komsebenzisi noma iphoyinti lokunikeza okusetshenziswayo (iphuzu lokuhlangana okuvamile).

Izidingo zalo mbhalo zisebenza ku-

• Ukufakwa kwe-PV okungaxhunyiwe ohlelweni lokusabalalisa ugesi emphakathini,
• Ukufaka kwe-PV ngokuhambisana nohlelo lokwabiwa kukagesi emphakathini,
• Ukufaka kwe-PV njengenye indlela yohlelo lokwabiwa kukagesi emphakathini,
• inhlanganisela efanelekile yalokhu okungenhla. Le dokhumenti ayihlanganisi izidingo ezithile zokufakwa kwamabhethri noma ezinye izindlela zokugcina amandla.

QAPHELA 1 Izidingo ezingeziwe zokufakwa kwe-PV ezinekhono lokugcina ibhethri ohlangothini lweDC ziyacatshangelwa.

QAPHELA 2 Lo mbhalo uhlanganisa izidingo zokuvikelwa kwamalungu afanayo e-PV athuthuka ngenxa yokusetshenziswa kwamabhethri ekufakweni kwe-PV.

Ezinhlelweni ezisebenzisa ama-DC-DC converters, izidingo ezingeziwe maqondana namandla wamandla nezinga lamanje, ukushintsha, kanye namadivayisi wokuvikela angasebenza. Lezi zidingo ziyacatshangelwa.

Inhloso yalo mbhalo ukubhekana nezidingo zokuphepha komklamo ezivela kuzimpawu ezithile zokufakwa kwe-PV. Izinhlelo ze-DC, kanye nokuhlelwa kwe-PV ikakhulukazi, kubeka izingozi ezithile ngaphezu kwalezo ezitholakala ekufakweni kwamandla kagesi okuvamile, kufaka phakathi amandla okukhiqiza nokugcina ama-arcs kagesi ngemisinga engekho emikhulu kunemisinga ejwayelekile yokusebenza.

Ekufakweni kwe-PV exhunywe kwi-PV izidingo zokuphepha zalo mbhalo, noma kunjalo, zincike kakhulu kwi-PCE ehambisana nokuhlelwa kwe-PV okuhambisana nezidingo ze-IEC 62109-1 ne-IEC 62109-2.
