Masana'antar PV tana da cewa: 2018 ita ce shekarar farko ta shuka mai amfani da wutar lantarki. An tabbatar da wannan jumla a fagen daukar hoto Photovoltaic Box 2018 Nanjing ya rarraba Photovoltaic charactic hanya! Masu shiga da masu rarraba duk ƙasar sun taru a cikin Nanjing don koyon ilimin Rarraba Power Power Power.
A matsayin ƙwararren masani a fagen Inverters, Renac koyaushe an sadaukar da kai ga ilimin kimiyyar. A shafin kula da horarwar Nanjing, an gayyaci mai sarrafa sabis na 'yan kasuwa na Renac don raba zabin Inverters da Ayyukan hankali. Bayan aji, an taimaka wa ɗalibai su bincika matsalolin da ke cikin gama gari da wutar lantarki kuma suka sami yabo baki ɗaya daga ɗalibai.
Tukwici:
1. Ba a nuna allon Inverter ba
Nazarin gazawar:
Ba tare da shigarwar DC ba, mai shiga cikin lCD yana ɗaukar nauyin DC.
Dalili mai yiwuwa:
(1) Vartage na bangaren bai isa ba, abin da shigarwar wutar lantarki yana ƙasa da farkon wutar lantarki, kuma mai jan hankali baya aiki. Haɗin lantarki yana da alaƙa da radiation na rana.
(2) An sake juyawa PV Inputal. Terminal PV yana da sanduna biyu, tabbatacce kuma mara kyau, kuma dole ne su dace da juna. Ba za a iya haɗa su da wasu kungiyoyi ba.
(3) Ba a rufe sayan DC ba.
(4) Lokacin da aka haɗa kirtani a cikin layi daya, ɗayan masu haɗin ba a haɗa su ba.
(5) Akwai wani gajeren da'irar a cikin module, yana haifar da babu sauran igiyoyi don aiki.
Magani:
Aunawa da injin shigar da DC na mai jan hankali tare da kewayon ƙarfin lantarki. Lokacin da ƙarfin lantarki al'ada ne, jimlar ƙarfin lantarki shine jimlar ƙarfin ƙarfin kowane ɓangaren kowane bangare. Idan babu wutar lantarki, to sai a bincika DC Swyard, mai haɗi, haɗin kebul, da abubuwan haɗin kai, da abubuwan haɗin kai; Idan akwai kayan haɗin abubuwa da yawa, raba damar gwaji.
Idan ana amfani da inverter na tsawon lokaci kuma babu wani dalili na waje, da'irar Inverder ba ta da kuskure. Adana injiniyan fasaha bayan tallace-tallace.
2. Ba a haɗa mai jan hankali ga hanyar sadarwa
Nazarin gazawar:
Babu wata alaka tsakanin mai jan hankali da grid.
Dalili mai yiwuwa:
(1) ba a rufe ba.
(2) An haɗa tashar fitarwa na AC ba a haɗa.
(3) A lokacin da wiring, babban tashar tashar fitarwa ta Inverter an kwance.
Magani:
Auna ƙarfin aikin AC na AC tare da kewayon ƙarfin lantarki. A karkashin yanayin al'ada, ya kamata fitowar tashar tashoshi tana da 220v ko 380V dutsen. Idan ba haka ba, bincika idan tashar haɗin haɗi tana kwance, idan an rufe sayayyar AC, kuma idan ana kunna wutar kare kariya.
3. Inverter PV overvolt
Nazarin gazawar:
DC voltage mai yawa ƙararrawa.
Dalili mai yiwuwa:
Yawan yawan abubuwan da aka gyara a cikin jerin abubuwan da ke haifar da wutar lantarki don wuce iyakar shigarwar wutar lantarki na inverter.
Magani:
Saboda halayen zazzabi na abubuwan da aka gyara, ƙananan zafin jiki, mafi girman wutar lantarki. Tsarin shigarwar lantarki kewayon kirtani mai lamba guda ɗaya ne 50-600v, kuma kewayon igiyar wutar lantarki ta kai tsakanin 350-400. Abubuwan shigarwar wutar lantarki na shigar da kirtani na uku shine 200 har zuwa gav. Kewayon bayan wutar lantarki yana tsakanin 550-700V. A cikin wannan kewayon ƙarfin lantarki, ingancin mai shiriya ya kasance da girma. Lokacin da radiation ya yi ƙasa da safe da maraice, zai iya samar da wutar lantarki, amma ba ya haifar da wutar lantarki ta wuce iyaka na wutar lantarki, yana haifar da ƙararrawa da tsayawa.
4. Ciki mai shigowa
Nazarin gazawar:
Resistancessular juriya na tsarin daukar hoto zuwa ƙasa kasa da 2 mehms.
Dalili mai yiwuwa:
SODLAR MODELES, akwatunan junction, Inverters, acable, tashoshin cakulan, tashar jiragen ruwa, da sauransu, suna da ɗan gajeren da'ira zuwa ƙasa ko lalacewar rufin. Tashar jiragen ruwa na PV da gidajen da ke da injin din AC suna kwance, sakamakon su a cikin kawar da ruwa.
Magani:
Cire haɗin grid, mai shiga tsakani, duba juriya da kowane bangare na ƙasa bi da, don fitar da wuraren matsalar, da kuma maye gurbin.
5. Grid kuskure
Nazarin gazawar:
Grid Voltage da mitar sun yi ƙasa sosai ko maɗaukaki.
Dalili mai yiwuwa:
A wasu yankuna, ba a sake gina hanyar cibiyar sadarwar karkara ba kuma babbar wutar lantarki ba ta cikin ikon kiyaye amincin tsaro.
Magani:
Yi amfani da multimeter don auna ƙarfin dutsen da mita, idan ya fita daga jiran Grid don komawa zuwa al'ada. Idan wutar lantarki ta al'ada ce, shi ne mai dubawa wanda ya gano gazawar jirgin. Cire duk dukkanin DC da AC na ACM na injin kuma bari indoverter sube na kimanin mintuna 5. Rufe wutar lantarki. Idan za'a iya sake rayuwa, idan ba za'a iya dawo da shi ba, tuntuɓi. Bayan injin fasaha na bayan ciniki.
