Isityalo samandla ehlobo se-photovoltaic iingxaki eziqhelekileyo kunye nezisombululo

Emva kokuqala kwehlobo, ukushisa okuphezulu kunye nemvula yezulu kwenzeka rhoqo, enokuthi ibe nefuthe elithile kwizityalo zamandla e-photovoltaic. Njengenxalenye engundoqo yesikhululo samandla sisonke, i-inverter inokuqonda uhlolo lwexesha lokwenyani lwedatha yokusebenza yesikhululo samandla, ukuqonda kwangethuba imeko yempilo yesixhobo, kunye nesilumkiso sempazamo ukunceda ukutshixa iindawo ezingaqhelekanga. Eli nqaku lilungise iingxaki eziqhelekileyo kunye nezisombululo, ngethemba lokwenza izikhululo zamandla e-photovoltaic "zivule ngokupheleleyo" kweli hlobo.

1. Ngaba i-impedance ye-insulation emhlabeni iphantsi kakhulu?
Uhlalutyo lwesizathu: imozulu imvula ehlotyeni, kwaye i-casing imanzi kwaye kulula ukungena emanzini; Iibhokisi zecandelo elingangeni manzi nazo zisenokungaphumeleli... Xa sijongene nezi ngxaki, owona myalezo wemposiso uxhaphakileyo kukuba "i-insulation impedance emhlabeni iphantsi kakhulu."
Isisombululo:
① Jonga intambo yeDC, indawo esecaleni, kunye nokungena kwamanzi kumbhobho. Uninzi lweengxaki ze-impedance zepaneli zepaneli zibangelwa umonakalo wentambo ye-DC, ebandakanya iintambo phakathi kwamacandelo, iintambo phakathi kwamacandelo kunye ne-inverter, ngakumbi iintambo ezikwikona kunye neentambo ezibekwe kwindawo evulekileyo ngaphandle kwemibhobho, ekufuneka iqwalaselwe ngononophelo. ikhangelwe
② Jonga i-DC okanye i-AC bushing. Ukuba akukho zizibuko zokuvuza zigcinwe okanye i-casing ibekwe ngendlela engafanelekanga, umthamo omkhulu wamanzi emvula uya kuqokelelwa kwi-casing, ekhokelela ekuthinteleni okuphantsi komgca.
③ I-inverter ye-Photovoltaic ayisekelwanga kakuhle. Ukuba i-inverter ayigxilwanga okanye iphantsi kakubi, iya kuchaphazela i-inverter ukuba ibone ngokuchanekileyo ixabiso le-impedance ye-insulation yecandelo emhlabeni, okubangela i-alamu yobuxoki.
​2. Iintsinjana ezilahlekileyo?
Uhlalutyo lwezizathu: Ihlobo sisiphango ngequbuliso esibhakabhakeni esiluhlaza, ukusilela kwamandla egridi yamandla kwenzeka amaxesha ngamaxesha, kwaye ikwayenye yezona nkcukacha zixhaphakileyo zempazamo.
Isisombululo:
(1) Qinisekisa ukuba igridi yamandla ivaliwe, ukuba igridi yamandla ivaliwe, linda igridi yamandla ukubuyisela umbane;
② Ukuba unikezelo lwamandla luqhelekileyo, sebenzisa i-multimeter ukulinganisa ukuba i-voltage ye-AC yokuphuma iqhelekile. Okokuqala, linganisa imveliso ye-inverter kwaye ukhangele ukuba ngaba icala lemveliso ye-inverter liphosakele. Ukuba akukho ngxaki, kukuphuka kwecala le-AC langaphandle, kufuneka kujongwe iswitshi yomoya, ibhuleki yesixhobo, ngaphezulu nangaphantsi komkhuseli wombane kunye nezinye izitshixo zokhuseleko zonakele kwaye zophukile.
3. Inverter LED akukho mboniso?
Uhlalutyo lwesizathu: Akukho galelo le-DC okanye unikezelo lwamandla ancedisayo aluqhelekanga, iswitshi ye-DC ayivalwanga, njl.
Isisombululo:
① Sebenzisa i-multimeter ukulinganisa igalelo lamandla ombane we-DC we-inverter. Ukuba i-voltage iyonke sisimbuku se-voltage yecandelo ngalinye, ingxaki yombane ayibandakanywa;
② Emva kokususa ingxaki ye-voltage, khangela ukuba i-DC switch, i-terminal, i-cable connector, kunye nezixhobo ziqhelekileyo ngokulandelelana.
​4. Ngaba ifeni yangaphandle inempazamo?
Uhlalutyo lwesizathu: Kumsebenzi wokwenyani, i-inverter ifakwa ikakhulu ngaphandle. Uthuli, izinambuzane, amasebe, kunye nezinye izinto ezinzima zingena kwi-fan compartment kwaye zithintele ukujikeleza. Kule meko, fan yangaphandle ayiqhelekanga.
Isisombululo:
① Jonga imo yokusebenza yefeni kwindawo, kwaye usebenzise izixhobo zokuhambisa iiblayidi zefeni ukususa izinto zangaphandle;
② Sebenzisa izixhobo ezifana nezomisi iinwele ukuvuthela uthuli;
③ Ukuba ezi zizathu zingasentla azinakubuyiselwa, ifeni isenokungakwazi ukunika amandla.
5. Ngaba unxibelelwano olukwiqonga lokubeka iliso aluqhelekanga?
Uhlalutyo lwesizathu: Umqokeleli akanxibelelani ne-inverter. Umqokeleli akaxhonywanga: ingxaki yophawu lwendawo yokuhlohla; Izizathu zangaphakathi zomqokeleli.
Isisombululo:
① Xa iqonga lokubeka iliso lingenako ukubeka iliso ubume be-inverter, umsebenzi kunye nabasebenzi bokugcina kufuneka baqale bagqibe ukuba ngaba umqokeleli obotshelelwe kwisikhululo samandla uyahambelana, nokuba umqokeleli kunye ne-inverter ziqhelekile ukuqhagamshelwa, kwaye ingaba i-inverter DC switch ivuliwe. .
② Qinisekisa ukuba oku ngasentla kuqhelekileyo, qhubeka ujonge isimo sesalathisi sokusebenza komqokeleli, ukuba ukukhanya kwenethiwekhi akukhanyisi, kubonisa ukuba isignali yenethiwekhi yendawo ihlwempuzekileyo, kufuneka ufake intambo yokwandisa unxibelelwano;
③ Ukuba isalathisi samandla sicimile, umqokeleli akaqhutywa, kwaye ungaphinda uyifake.
