Kulo nyaka, i-El Niño phenomenon inokuthi yenzeke, okanye ihlobo elitshisa kakhulu kwimbali liya kungenisa, eliya kuzisa imingeni enzima kakhulu kwizityalo zamandla e-photovoltaic.
1.1 Impembelelo yobushushu obuphezulu kumacandelo
Ukushisa okugqithisileyo kuya kunciphisa ukusebenza kunye nobomi bamacandelo, njengama-inductors, i-electrolytic capacitors, iimodyuli zamandla, njl.
I-Inductance:Kwiqondo lokushisa eliphezulu, i-inductance ilula ukuba ihluthe, kwaye i-inductance egcweleyo iya kuncipha, okubangelwa ukunyuka kwexabiso eliphezulu lexesha elisebenzayo, kunye nomonakalo kwisixhobo samandla ngenxa yokugqithisa.
I-Capacitor:Kwii-electrolytic capacitors, ubude bobomi bee-electrolytic capacitors buncitshiswa ngesiqingatha xa ubushushu be-ambient bunyuka nge-10°C.IAluminiyam i-electrolytic capacitors ngokuqhelekileyo isebenzisa ububanzi beqondo lobushushu obuyi -25~+105°C, kwaye ii-filimi capacitors ngokuqhelekileyo zisebenzisa iqondo lobushushu eliyi -40~+105°C.Ngoko ke, ii-inverters ezincinci zihlala zisebenzisa ii-capacitors zefilimu ukuphucula ukulungelelaniswa kwee-inverters kumaqondo aphezulu aphezulu.
Ubomi be-capacitors kumaqondo okushisa ahlukeneyo
Imodyuli yamandla:Ukuphakama kweqondo lokushisa, ukuphakama kweqondo lokushisa kwe-chip xa imodyuli yamandla isebenza, eyenza imodyuli ithwale uxinzelelo oluphezulu lwe-thermal kwaye inciphise kakhulu ubomi benkonzo.Emva kokuba iqondo lokushisa ligqithise umda weqondo lokushisa, liya kubangela ukuphuka kwe-thermal yemodyuli.
1.2 Amanyathelo oKuchitha ubushushu be-Inverter
I-inverter inokusebenza ngaphandle kwi-45 ° C okanye ubushushu obungaphezulu.Uyilo lokutshatyalaliswa kobushushu be-inverter yindlela ebalulekileyo yokuqinisekisa ukusebenza okuzinzile, okukhuselekileyo kunye nokuthembekileyo kwecandelo ngalinye lombane kwimveliso ngaphakathi kweqondo lokushisa.Iqondo lokushisa loxinzelelo lwe-inverter yi-inductor yokunyusa, i-inverter inductor, kunye nemodyuli ye-IGBT, kwaye ubushushu buyachithwa nge-fan yangaphandle kunye ne-back heat sink.Oku kulandelayo lijiko lokunciphisa ubushushu be-GW50KS-MT:
Ukunyuka kobushushu be-Inverter kunye nokuwa komthwalo wegophe
1.3 Ulwakhiwo oluchasene nobushushu obuphezulu
Kuphahla lwemizi-mveliso, iqondo lobushushu lihlala liphezulu kunolo lisemhlabeni.Ukuze uthintele i-inverter ekukhanyeni kwelanga elichanekileyo, i-inverter ifakwe ngokubanzi kwindawo enomthunzi okanye i-baffle yongezwa phezulu kwi-inverter.Kufuneka kuqatshelwe ukuba indawo yokusebenza kunye nokugcinwa kufuneka igcinwe kwindawo apho i-fan inverter ingena kwaye iphuma emoyeni kunye ne-fan yangaphandle.Oku kulandelayo yi-inverter ene-air intake yasekhohlo nasekunene kunye nokuphuma.Kuyimfuneko ukugcina indawo eyaneleyo kumacala omabini e-inverter, kwaye ugcine umgama ofanelekileyo phakathi kwe-visor yelanga kunye nomphezulu we-inverter.

Iindudumo kunye nemvula ehlotyeni.
2.1 Umbane oguquliweyo kunye naManyathelo oKhuseleko lwemvula
Imilinganiselo yokukhusela umbane yombane:Amacala e-AC kunye ne-DC ye-inverter axhotyiswe ngezixhobo zokukhusela umbane ophezulu, kunye nabafowunelwa abomileyo bane-alamu yokukhusela umbane, okulungele imvelaphi ukwazi imeko ethile yokukhusela umbane.
I-Inverter yokuthintela imvula kunye nemilinganiselo yokuchasana nokuhlwa:I-inverter ithatha inqanaba eliphezulu lokukhusela i-IP66 kunye nenqanaba le-C4 & C5 lokuchasana ne-corrosion ukuqinisekisa ukuba i-inverter iyaqhubeka isebenza phantsi kwemvula enkulu.
Uxhulumaniso lobuxoki lwe-photovoltaic connector, ukungena kwamanzi emva kokuba ikhebula lonakaliswe, okubangelwa isiphaluka esifutshane kwicala le-DC okanye ukuvuza komhlaba, okubangela ukuba i-inverter imise.Ke ngoko, umsebenzi wokufumanisa i-arc ye-DC ye-inverter nayo ibaluleke kakhulu.
2.2 Isicwangciso esiliqili sokukhuselwa kombane (ukwakha).
Yenza umsebenzi omhle wenkqubo yomhlaba, kubandakanywa iiterminals zecandelo kunye nee-inverters.
Amanyathelo okukhusela umbane kwipaneli yelanga kunye ne-inverter
Ihlobo elineemvula linokubangela ukuba ukhula lukhule kwaye lube nomthunzi.Xa amanzi emvula ehlamba amacandelo, kulula ukubangela ukuqokelela uthuli kwimida yamacandelo, okuya kuchaphazela umsebenzi wokucoca olandelayo.
Yenza umsebenzi omhle ekuhloleni inkqubo, jonga rhoqo ukugquma kunye neemeko zokungangeni manzi kwezihlanganisi ze-photovoltaic kunye neentambo, jonga ukuba iintambo zifakwe emanzini emvula, kunye nokuba kukho ukuguga kunye neentanda kwi-sheath yokufakelwa kwentambo.
Ukuveliswa kwamandla e-Photovoltaic kukuvelisa amandla emozulu yonke.Ukushisa okuphezulu kunye neendudumo ehlotyeni ziye zazisa imingeni enzima ekusebenzeni nasekugcinweni kwezityalo zamandla e-photovoltaic.Ukudibanisa i-inverter kunye noyilo lweplanti yamandla ngokubanzi, u-Xiaogu unika iingcebiso malunga nokwakhiwa, ukusebenza kunye nokugcinwa, kwaye unethemba lokuba luncedo kumntu wonke.
