Esikhathini sanamuhla esithuthuka ngokushesha samandla aluhlaza, ukukhiqizwa kukagesi we-photovoltaic (PV), njengomunye wemithombo yamandla ahlanzekile ethembisa kakhulu futhi ebheke phambili, kancane kancane kuba amandla abalulekile aqhuba uguquko lwamandla omhlaba. Kodwa-ke, amasistimu e-PV, ikakhulukazi ingxenye yawo eyinhloko—i-inverter—ibhekana nezinselele ezinkulu ezindaweni ezingaphandle. Isimo sezulu esibi kakhulu, izivunguvungu zothuli, nezinye izici zemvelo azihloli nje kuphela ukuqina nokuthembeka kweziguquli kodwa ziphinde zibe nomthelela oqondile ekusebenzeni kahle kokukhiqizwa kwamandla kanye nokuzinza kwesistimu ye-PV. Isilinganiso sokuvikela se-IP65 sibhekana ngempumelelo nalezi zinselele.
Iyini i-IP65?
Isilinganiso se-IP, noma i-Ingress Protection, iyindinganiso esungulwe yi-International Electrotechnical Commission (IEC), ikakhulukazi i-IEC 60529, esetshenziselwa ukuhlola izinga lokuvikela lezindawo ezivalekile zikagesi ezintweni zangaphandle.
I-"5" ku-IP65 imele isilinganiso esingangenwa amanzi, okusho ukuthi isiguquli singakwazi ukumelana namajethi amanzi anomfutho ophansi ukusuka kunoma iyiphi indawo, iqinisekise ukuthi sisebenza ngokujwayelekile ezimeni zesimo sezulu esibi njengemvula enkulu noma izikhukhula. Lokhu kusebenza okungangeni kwamanzi kuvimbela amanzi ukuthi angangeni ku-inverter, ukugwema izinkinga ezifana namasekhethi amafushane nokuvuza kukagesi, ngaleyo ndlela kuqinisekisa ukusebenza okuqhubekayo nokuzinzile kwesistimu ye-PV.
I-"6" ku-IP65 ibhekisela ekuvikelweni kothuli, okusho ukuthi isiguquli sivikelwe ngokuphelele ekungeneni kothuli. Lesi sici sibaluleke kakhulu ezimweni zezulu ezinzima njengezivunguvungu zothuli. Ivimbela uthuli nezinye izinhlayiya ekugugulekeni nasekungcoliseni izingxenye zangaphakathi ze-inverter, inciphisa izinkinga ezifana nokuchithwa okubi kokushisa namasekhethi amafushane okubangelwa ukunqwabelana kothuli, futhi ngaleyo ndlela andise isikhathi sokuphila se-inverter.
Kungani Khetha IP65?
1.Ukuguquguquka Kwemvelo Okuthuthukisiwe:Iziguquli ze-PV zivame ukufakwa ngaphandle futhi zichayeke ezimweni ezinzima zemvelo njengokukhanya kwelanga, umoya, imvula, nothuli. Isilinganiso sokuvikela se-IP65 siqinisekisa ukuthi isiguquli singasebenza ngokujwayelekile kulezi zimo ezimbi kakhulu, sithuthukise kakhulu ukuthembeka nempilo yedivayisi.
2.Ukuzinza Kwesistimu Okuthuthukisiwe:Njengengxenye eyinhloko yohlelo lwe-PV, ukuzinza kwe-inverter kuhlobene ngokuqondile nokusebenza kahle kokukhiqizwa kwamandla kanye nokuphepha kokusebenza. Isilinganiso se-IP65 sehlisa ukuhluleka kwe-inverter okubangelwa izici zemvelo, ukwehlisa izindleko zokulungisa kanye nokuthuthukisa ukuzinza nokuthembeka okuphelele kwesistimu ye-PV.
3.Ukuqinisekisa Izinzuzo Zomsebenzisi:Kubatshalizimali bemishini kagesi ye-PV kanye nama-opharetha, ukusebenza okuzinzile kwe-inverter kusho ukukhiqizwa kwamandla kagesi aphezulu kanye nezindleko zokunakekela eziphansi. Isilinganiso se-IP65 sinikeza ukuzinza kwesikhathi eside kanye nesiqiniseko semali engenayo, sinciphisa ubungozi bokutshalwa kwezimali.
4. Ukukhuthaza Ukuthuthukiswa Kwamandla Aluhlaza:Njengoba isidingo somhlaba wonke samandla aluhlaza siqhubeka sikhula, ukusebenza nokuzinza kwama-inverters kube yizinto ezibalulekile ezibeka umkhawulo ekuthuthukisweni kwamandla aluhlaza. Ama-inverter anesilinganiso se-IP65, ngokusebenza kwawo okuhle kakhulu namathemba okusebenza abanzi, ahola ukukhula okusheshayo kwemboni yamandla aluhlaza.
