Imboni ye-PV inesisho esithi: 2018 ngunyaka wokuqala wesitshalo samandla we-Photovoltaic Power. Lesi sigwebo siqinisekisiwe emkhakheni we-Photovoltaic Photovoltaic Box 2018 Nanjing asatshalaliswa i-Photovoltaic Technology Constation Course! Abafaki kanye nabasabalalisi kulo lonke izwe eliqoqwe eNANJIng ukufundela ngokuhlelekile ulwazi lwe-Photovoltaic Power Plant Construction.
Njengochwepheshe emkhakheni we-Photovoltaic Inverters, uRenac ubelokhu enikelwe kwisayensi ye-Photovoltaic. Endaweni yokuqeqesha ye-nanjing, umphathi wesevisi yeRenac Technical wacelwa ukuba abelane ngokhetho lwama-inverters kanye nezinsizakalo ezihlakaniphile. Ngemuva kwekilasi, abafundi basizwa ukuba bahlaziye izinkinga ezivamile zeziteshi zamandla kagesi ze-Photovoltaic futhi bathola ukudunyiswa okuvela kubafundi.
Amathiphu:
1. Isikrini se-Inverter asikhonjiswa
Ukuhlaziywa Kwehluleka:
Ngaphandle kokufakwa kwe-DC, i-Inverter LCD inikwa amandla yi-DC.
Izimbangela Okungaba khona:
(1) Amandla kagesi engxenye awanele, i-voltage yokufaka iphansi kune-voltage yokuqala, futhi i-inverter ayisebenzi. I-Contnent Voltage ihlobene nemisebe yelanga.
(2) I-terminal yokufaka ye-PV ibuyiselwa emuva. I-terminal ye-PV inezigxobo ezimbili, okuhle nokubi, futhi kufanele zihambisane. Azikwazi ukuxhunywa ngokubuyela emuva namanye amaqembu.
(3) I-DC switch ayivaliwe.
(4) Lapho intambo ixhumeke ngokufana, omunye wabaxhumi akaxhunyiwe.
(5) Kukhona umjikelezo omfushane kwimodyuli, okubangelwa ezinye izintambo ukuthi zisebenze.
Isixazululo:
Kala i-VCOP yokufaka ye-DC ye-inverter nge-Voltage Range of Multimeter. Lapho i-voltage ijwayelekile, i-voltage ephelele yisamba se-voltage yengxenye ngayinye. Uma kungekho voltage, bese uhlola ukushintshwa kwe-DC, ibhulokhi ye-terminal, isixhumi sekhebula kanye nezinto ngokulandelana; Uma kunezakhi eziningi, ukufinyelela okuhlukile kokuhlolwa.
Uma i-inverter isetshenziselwa isikhathi esithile futhi ayikho imbangela yangaphandle etholakala, umjikelezo wehardware we-inverter unephutha. Xhumana nonjiniyela wezobuchwepheshe ngemuva kokuthengisa.
2. I-inverter ayixhunyiwe kwinethiwekhi
Ukuhlaziywa Kwehluleka:
Akukho ukuxhumana phakathi kwe-inverter negridi.
Izimbangela Okungaba khona:
(1) Ukushintshwa kwe-AC akuvaliwe.
(2) I-ac autput terminal ye-inverter ayixhunyiwe.
(3) Lapho i-wiring, i-terminal ephezulu ye-inverter aketput terminal iyakhululwa.
Isixazululo:
Kala i-AC Output VolTage ye-inverter nge-Voltage Range of Multimeter. Ngaphansi kwezimo ezijwayelekile, i-terminal yokuphuma kufanele ibe nama-voltage angama-220 noma ama-380v. Uma kungenjalo, hlola ukuthi ngabe i-terminal yokuxhuma ikhululekile, uma ukushintshwa kwe-AC kuvaliwe, futhi uma ukushintshwa kokuvikela ukuvuza kunqanyuliwe.
3. Inverter PV ngaphezulu
Ukuhlaziywa Kwehluleka:
I-Alarm ephakeme kakhulu ye-DC.
Izimbangela Okungaba khona:
Inombolo eyeqile yezakhi ochungechungeni ibangela ukuthi ivolushwe idlule umkhawulo we-voltage wokufaka we-inverter.
Isixazululo:
Ngenxa yezimpawu zokushisa zezakhi, okuphansi izinga lokushisa, kukhuphuka amavolosi. Uhla lwe-voltage olufakiwe lwesi-inverter yesigaba esisodwa se-munye ngu-50-600V, futhi uhla lwe-voltage oluhlongozwayo luphakathi kuka-350-400. Uhla lwe-voltage olufakiwe lwe-inverter yesigaba sesigaba ezintathu ngu-200-1000V. Ibanga le-post-voltage liphakathi kuka-550-700V. Kuleli voltage bubanzi, ukusebenza kahle kwe-inverter kuphezulu. Lapho imisebe iphansi ekuseni nakusihlwa, ingakhipha ugesi, kepha akubangeli ukuthi ivota lidlule umkhawulo ophezulu we-inverter voltage, okwenza i-alamu nokuma.
4. I-Inverter Inverter Ukufakwa Kwephutha
Ukuhlaziywa Kwehluleka:
Ukumelana kokufakelwa kohlelo lwe-Photovoltaic kuya emhlabathini kungaphansi kwama-2 Megohms.
Izimbangela Okungaba khona:
Amamojula we-solar, amabhokisi we-jungction, amakhethini we-DC, ama-inverters, amakhebuli e-ac, ama-terminals we-wiring, njll. Izikhungo ze-PV kanye nezindlu ze-AC Wiring zikhululekile, ziphumela ekungeneni kwamanzi.
Isixazululo:
Nqamula igridi, inverter, hlola ukumelana kwengxenye ngayinye emhlabathini nakho, thola amaphuzu enkinga, bese ubuyisela okunye.
5. Iphutha legridi
Ukuhlaziywa Kwehluleka:
I-grid voltage kanye nemvamisa iphansi kakhulu noma iphakeme kakhulu.
Izimbangela Okungaba khona:
Kwezinye izindawo, inethiwekhi yasemakhaya ayikakhiwa kabusha futhi i-grid voltage ayikho ngaphakathi kweMithetho Yezokuphepha.
Isixazululo:
Sebenzisa i-multimeter ukukala i-grid voltage kanye nemvamisa, uma kungenzeki ukulinda igridi ukubuyela kokujwayelekile. Uma igridi yamandla ijwayelekile, yi-inverter ethola ukwehluleka kwebhodi yesekethe. Nqamula yonke imikhawulo ye-DC ne-AC yomshini bese uvumele i-Inverter ikhiphe imizuzu emi-5. Vala ukunikezwa kwamandla. Uma kungavuselelwa kabusha, uma kungeke kubuyiselwe, thintana. Unjiniyela wezobuchwepheshe ngemuva kokuthengisa.
