Ehlobo, izitshalo zamandla ze-Photovoltaic zithinteka yisimo sezulu esibi esinjengamazinga okushisa aphezulu, umbani kanye nemvula enkulu. Ungawuthuthukisa kanjani ukuqina kwezitshalo zamandla ze-Photovoltaic ngokombono womklamo we-inverter, ukwakhiwa kwamandla aphelele nokwakha?
01
Isimo sezulu esishisayo
-
Kulonyaka, kungenzeka ukuthi ihlobo le-El Niño lingavela, noma ihlobo elishisa kakhulu emlandweni lizovela kulo, elizoletha izinselelo ezinzima kakhulu ku-Photovoltaic Power Plants.
1.1 Umphumela wokushisa okuphezulu kwizakhi
Ukushisa ngokweqile kuzonciphisa ukusebenza nokuphila kwezakhi, njenge-inductors, ama-electrolytic capacitors, amamojula wamandla, njll.
I-Inductance:Ekushiseni okuphezulu, ukudonswa okulula kulula ukugcwala, futhi ukwehla kwe-waturance okugcwele kuzokwehla, okuholela ekwandeni kwenani eliphakeme lamanje, kanye nomonakalo kwidivaysi yamandla ngenxa yamanje.
Capacitor:Kwaba-electrolytic capacitor, isikhathi sokuphila sama-capacitors we-electrolytic ancishiswa ngesigamu lapho izinga lokushisa elizwakalayo likhuphuka ngo-10 ° C. Ama-capacitors we-Aluminium electrolytic ngokuvamile asebenzisa uhla lokushisa lwe-25 ~ + 105 ° C, nama-capacitors amafilimu ngokuvamile asebenzisa uhla lokushisa lwe--40 ~ + 105 ° C. Ngakho-ke, ama-infterter amancane avame ukusebenzisa ama-capacitor amafilimu ukuthuthukisa ukuvumelana nezimo zabakwa-Inverters kuya emazingeni okushisa aphezulu.
Impilo yama-capacitors emazingeni okushisa ahlukene
Module Power:Ukushisa okuphezulu, okuphezulu kokushisa kwe-chip lapho imodyuli yamandla isebenza, okwenza imodyuli ibhele kakhulu ukucindezelwa okushisayo futhi ifinyeze kakhulu impilo yenkonzo. Lapho izinga lokushisa lidlula umkhawulo wokushisa we-junction, lizodala ukuwohloka okushisayo kwemodyuli.
1.2 Izindlela zokunciphisa ukushisa ukushisa
I-inverter ingahle isebenze ngaphandle ngo-45 ° C noma izinga lokushisa eliphakeme. Umklamo wokuhlanza ukushisa we-inverter kuyindlela ebalulekile yokuqinisekisa ukusebenza okuzinzile, okuphephile futhi okuthembekile kwengxenye ngayinye ye-elekthronikhi emkhiqizweni ophakathi kokushisa okusebenzayo. Iphuzu lokuhlushwa lokushisa le-inverter liyi-inductor ye-inductor, i-inverter inductor, kanye nemodyuli ye-IGBT, futhi ukushisa kuhlakazeke ngo-fan wangaphandle kanye nokushisa okushisayo. Okulandelayo izinga lokushisa elisungula ijika le-GW50S-MT:
Ukushisa kwe-Inverter Ukuvuka bese kuwa ijika lomthwalo
1.3 Isu lokushisa eli-anti-high
Ophahleni lwezimboni, izinga lokushisa livame ukuphakama kunalelo emhlabathini. Ukuze uvikele i-inverter ukuthi ivezwe elangeni eliqondile, i-inverter ngokuvamile ifakwe endaweni enomthunzi noma i-anphafle ingezwe ngaphezulu kwe-inverter. Kumele kwaziwe ukuthi isikhala sokusebenza nokugcinwa kufanele sigcinwe esimweni lapho abalandeli be-Inverter bangena futhi baphuma khona nomoya kanye nomlandeli wangaphandle. Okulandelayo i-inverter enesokunxele nesokunxele sokudla nokwazi ukuphuma. Kuyadingeka ukugcina isikhala esanele ezinhlangothini zombili ze-inverter, bese sibeka ibanga elifanele phakathi kwe-visor yelanga nenhla kwe-inverter.

TIsimo sezulu saseKhosi
-
Ukuduma kwezulu kanye nezivunguvungu zemvula ehlobo.
2.1 Inverter Lightning kanye nezindlela zokuvikela imvula
Izindlela zokuvikela umbaniIzinhlangothi ze-AC ne-DC zifakwe amadivaysi aphezulu okuvikela umbani, futhi oxhumana nabo omile banokulayishwa kombani okuvikelwa umbani, okulungele isizinda sokwazi isimo esithile sokuvikelwa kombani.
Inventer-emvula-proof kanye nezindlela zokulwa nokulwa nokubhujiswa:I-Inverter yamukela izinga eliphakeme lokuvikela i-IP66 kanye ne-C4 & C5 anti-cormonion level ukuqinisekisa ukuthi i-inverter iyaqhubeka nokusebenza ngaphansi kwemvula enkulu.
Ukuxhumeka okungamanga kwesixhumi se-Photovoltaic, ukungena kwamanzi ngemuva kokuthi ikhebula kulimele, okuholela ekuzuzeni okufushane ohlangothini lwe-DC noma ekuvuzeni komhlaba, okwenza i-inverter iyeke. Ngakho-ke, umsebenzi wokutholwa kwe-DC ARC we-Inverter ubuye ubaluleke kakhulu.
2.2 Isu Lokuvikela Umbani (Ukwakha) Isu
Yenza umsebenzi omuhle wohlelo lwendlebe, kufaka phakathi ama-terminals ahlukahlukene kanye nama-inverters.
Izindlela zokuvikela umbani kuphaneli yelanga ne-inverter
Imvula yemvula nayo ingadala ukhula lukhule kanye nezingxenye zemithunzi. Lapho amanzi emvula egeza izakhi, kulula ukudala ukunqwabelana uthuli emiphethweni yezakhi, ezizothinta umsebenzi wokuhlanza olandelayo.
Yenza umsebenzi omuhle ekuhlolweni kwesistimu, njalo hlola ukufakwa kanye nezimo ezingenamanzi zezixhumi ze-Photovoltaic kanye nezintambo, bheka ukuthi izintambo zifakwe kancane kancane kumanzi emvula, nokuthi ngabe kukhona ukuguga okufakwayo kwentambo.
Isizukulwane samandla we-Photovoltaic siwukugcina amandla wesimo sezulu. Izinga lokushisa eliphakeme kanye nokuduma kwezulu ehlobo kulethe izinselelo ezinzima ekusebenzeni nasekugcinweni kwezitshalo zamandla ze-Photovoltaic. Ukuhlanganisa i-inverter kanye nomklamo we-Power Plant ophelele, i-XIAOGU inikeza iziphakamiso zokwakha, ekusebenzeni nasekulungiseni, futhi amathemba okusiza wonke umuntu.
