Ehlobo, izitshalo zamandla e-photovoltaic zithinteka esimweni sezulu esibi njengokushisa okuphezulu, umbani nemvula enkulu. Indlela yokuthuthukisa ukuzinza kwezitshalo zamandla e-photovoltaic ngokombono we-inverter design, umklamo jikelele wesitshalo samandla kanye nokwakhiwa?
01
Isimo sezulu esishisayo
-
Kulo nyaka, isenzakalo se-El Niño singase senzeke, noma ihlobo elishisa kakhulu emlandweni lizongena, elizoletha izinselele ezinzima kakhulu ezitshalweni zamandla e-photovoltaic.
1.1 Umthelela wokushisa okuphezulu ezintweni
Izinga lokushisa elidlulele lizonciphisa ukusebenza nokuphila kwezingxenye, njengama-inductors, ama-electrolytic capacitor, amamojula wamandla, njll.
I-Inductance:Emazingeni okushisa aphezulu, i-inductance kulula ukugcwaliswa, futhi i-inductance egcwele izokwehla, okuholela ekwenyukeni kwenani eliphakeme lamanje lokusebenza, kanye nokulimala kudivayisi yamandla ngenxa yokudlulela kwamanje.
I-Capacitor:Kuma-electrolytic capacitor, isikhathi sokuphila sama-electrolytic capacitor sincipha ngohhafu lapho izinga lokushisa le-ambient likhuphuka ngo-10°C. Ama-Aluminium electrolytic capacitor ngokuvamile asebenzisa izinga lokushisa elingu-25~+105°C, futhi ama-filimi capacitor ngokuvamile asebenzisa izinga lokushisa elingu--40~+105°C. Ngakho-ke, ama-inverters amancane avame ukusebenzisa ama-capacitor wefilimu ukuthuthukisa ukuguquguquka kwama-inverters emazingeni okushisa aphezulu.
Ukuphila kwama-capacitor emazingeni okushisa ahlukene
Imojula yamandla:Uma izinga lokushisa liphakeme, izinga lokushisa lokuhlangana liphakeme kakhulu lapho imojula yamandla isebenza, okwenza imojuli ithwale ukucindezeleka kokushisa okuphezulu futhi ifinyeze kakhulu impilo yesevisi. Uma izinga lokushisa lidlula umkhawulo wezinga lokushisa lokuhlangana, lizobangela ukuwohloka kokushisa kwemojuli.
1.2 Izinyathelo Zokushabalalisa Ukushisa Kwe-Inverter
I-inverter ingase isebenze ngaphandle ku-45°C noma izinga lokushisa eliphakeme. Umklamo wokukhipha ukushisa we-inverter uyindlela ebalulekile yokuqinisekisa ukusebenza okuzinzile, okuphephile nokuthembekile kwengxenye ngayinye ye-elekthronikhi emkhiqizweni ngaphakathi kwezinga lokushisa elisebenzayo. Iphoyinti lokugxila kwezinga lokushisa le-inverter yi-boost inductor, i-inverter inductor, nemojula ye-IGBT, futhi ukushisa kukhishwa ngefeni yangaphandle kanye nesinki yokushisa yangemuva. Okulandelayo ijika lezinga lokushisa le-GW50KS-MT:
I-Inverter izinga lokushisa liyakhuphuka kanye nejika lomthwalo wokuwa
1.3 Isu lokwakha elilwa nokushisa okuphezulu
Ophahleni lwezimboni, izinga lokushisa livame ukuphakama kunalelo eliphansi. Ukuze uvimbele i-inverter ukuthi ingavezwa elangeni eliqondile, i-inverter ngokuvamile ifakwa endaweni enomthunzi noma i-baffle yengezwe phezulu kwe-inverter. Kumele kuqashelwe ukuthi isikhala sokusebenza nokugcinwa kufanele sigcinwe endaweni lapho i-fan ye-inverter ingena futhi iphuma emoyeni kanye ne-fan yangaphandle. Okulandelayo i-inverter enomoya wesokunxele nakwesokudla kanye nokuphumayo. Kuyadingeka ukugcina isikhala esanele ezinhlangothini zombili ze-inverter, futhi ugcine ibanga elifanele phakathi kwe-visor yelanga nangaphezulu kwe-inverter.

Tisiphepho sezulu

Ukuduma nemvula ehlobo.
2.1 I-Inverter Lightning kanye nezinyathelo Zokuvikela Imvula
Izinyathelo zokuvikela umbani we-inverter:Izinhlangothi ze-AC ne-DC ze-inverter zifakwe amadivayisi wokuvikela umbani wezinga eliphezulu, futhi abathintwayo abomile banokulayishwa kwe-alamu yokuvikela umbani, okulungele ingemuva ukwazi isimo esithile sokuvikela umbani.
Izinyathelo ze-Inverter zokuvikela imvula nezokunqanda ukugqwala:I-inverter yamukela ileveli yokuvikela ephezulu ye-IP66 kanye neleveli ye-C4&C5 yokunqanda ukugqwala ukuze kuqinisekiswe ukuthi isiguquli siyaqhubeka nokusebenza ngaphansi kwemvula enkulu.
Ukuxhumeka okungamanga kwesixhumi se-photovoltaic, ukungena kwamanzi ngemva kokulimala kwekhebula, okuholela kumjikelezo omfushane ohlangothini lwe-DC noma ukuvuza komhlabathi, okubangela ukuba i-inverter ime. Ngakho-ke, umsebenzi wokutholwa kwe-DC arc we-inverter nawo ubaluleke kakhulu.
2.2 Isu lokuvikela umbani (ukwakha) lilonke
Yenza umsebenzi omuhle wesistimu ye-earthering, kufaka phakathi amatheminali wezingxenye nama-inverters.
Izinyathelo zokuvikela umbani kuphaneli yelanga kanye ne-inverter
Ihlobo elinemvula lingabangela nokhula ukuba lukhule futhi lube nomthunzi izingxenye. Lapho amanzi emvula egeza izingxenye, kulula ukubangela ukuqoqwa kothuli emaphethelweni ezingxenye, okuzothinta umsebenzi wokuhlanza olandelayo.
Yenza umsebenzi omuhle ekuhloleni isistimu, hlola njalo ukuvaleka kanye nezimo zokungangeni kwamanzi kwezixhumi ze-photovoltaic nezintambo, bheka ukuthi izintambo zicwiliswe kancane yini emanzini emvula, nokuthi kukhona yini ukuguga nokuqhekeka emgodleni wokufaka ikhebula.
Ukukhiqiza amandla e-Photovoltaic kuwukukhiqiza amandla asebenzisa isimo sezulu sonke. Izinga lokushisa eliphezulu nokuduma kwezulu ehlobo kulethe izinselele ezinzima ekusebenzeni nasekugcinweni kwezitshalo zamandla e-photovoltaic. Ihlanganisa i-inverter kanye nomklamo wesikhungo sikagesi usuwonke, u-Xiaogu unikeza iziphakamiso ngokwakhiwa, ukusebenza nokunakekelwa, futhi uthemba ukuba usizo kuwo wonke umuntu.
