Umbulali Wezitshalo Zamandla E-Photovoltaic-DC Arc

Ngenxa yezidingo zokungathathi hlangothi kwekhabhoni kanye nokukhuphuka kwekhabhoni, imboni yamandla entsha isithandwa kakhulu.Wonke umuntu uya ngokuya evumelana neziteshi zamandla e-photovoltaic, futhi abantu abaningi ngokwengeziwe bangena embonini ye-photovoltaic.Kodwa-ke, izinga labantu abathintekayo kulo mkhakha alilingani, futhi abantu abaningi abanaki ama-DC arcs, okuholela enanini elikhulu lezingozi.

I-Arc iwuhlobo lokukhishwa kwegesi.Inhlansi esheshayo edalwa ukudlula kwamanje endaweni ethile evikelayo, njengomoya, ibizwa ngokuthi i-arc.Kokubili ama-arcs aqondile amanje kanye namanje ashintshanayo.Kwesinye isikhathi uma sixhuma isokhethi, sizobona izinhlansi, okuyi-AC arc.Kuhlelo lwe-DC, i-arc enjalo ebangelwa intambo yeseli ye-photovoltaic ibizwa ngokuthi i-DC arc.Ngokuphambene, izinhlelo ze-DC zinamathuba amaningi okukhiqiza ama-arcs kunezinhlelo ze-AC, futhi uma i-arc yenzeka, kuba nzima kakhulu ukucisha i-arc.

Esiteshini samandla e-photovoltaic, amaphaneli e-photovoltaic akhipha ugesi we-DC, oguqulwa ube ngugesi we-AC kuphela ngemva kokudlula ku-inverter ye-photovoltaic.Ama-voltage amaphaneli e-PV aphakeme kakhulu, avela ku-volts angamakhulu ambalwa kuya ku-1500 V. Eqinisweni, amashumi ambalwa ama-volts anele ukukhiqiza i-DC arc, engakhiqiza amazinga okushisa aphezulu afika ku-4200 degrees.Lapho amaphaneli amane e-photovoltaic ehlanganiswa ndawonye, ​​i-voltage evamile izofinyelela cishe ku-120 volts.Ukuxhumana okuhle nokubi kwezintambo ngokushesha kukhiqiza i-arc ye-DC, futhi emizuzwaneni embalwa nje, izinga lokushisa eliphezulu livumela ikhebula le-DC yethusi ukuba lincibilike khona manjalo bese liphenduka libe amathonsi ethusi phansi.Iphuzu lokuncibilika lethusi lingama-degree angu-1083, ithusi elincibilikisiwe uma liconsa ophahleni lwamapulangwe oluningi lwemiphumela ye-villa ayinakucatshangelwa, okungenzeka kubangele umlilo, omunye womlilo we-villa yaseYurophu ubangelwa uphahla lwe-photovoltaic power plant DC arc ebangelwa. .Ngakho-ke, ukuvikelwa kwe-arc ye-DC yezitshalo zamandla e-photovoltaic kubaluleke kakhulu.

Ngakho-ke, kungani isiteshi samandla e-photovoltaic sikhiqiza i-DC arc?Izizathu eziyinhloko zokuvela kwe-DC arc yilezi: i-terminal noma uxhumano lwe-fuse alucindezelwa, ibhawudi yebhasi ayiqinisiwe, uxhumano lufakwe i-oxidized, ukufakwa kwe-wire kuncishisiwe, ukufakwa kwemishini kunesici, njalonjalo.

Yiziphi izingozi ze-DC arc ezitshalweni zamandla e-photovoltaic?Okokuqala wukulimala kwemishini.Amabhokisi enhlanganisela, amakhabethe e-DC, izingxenye zephaneli yebhethri, izixhumi, amabhokisi okuhlangana, njll. ashisiwe.Okwesibili ukulahlekelwa amandla.Noma yikuphi ukwehluleka kuzodala ukukhiqizwa kwamandla amancane noma angabikho nhlobo.Okwesithathu yizingozi zokuphepha.Imililo ingafaka engozini ukuphepha komuntu siqu nempahla.

Angakanani amathuba okuthi i-arc kagesi ikhiqizwe esiteshini samandla se-PV?Thatha isiteshi sikagesi esingu-10MW njengesibonelo, kunezixhumi zamabhokisi ezihlanganisayo ezingaba ngu-80,000 kanye namabhulokhi wokugcina angu-4,000, kanye namajoyinti okushisela angaphakathi amaphaneli ebhethri, iKhabhinethi ye-DC kanye namanodi angaphakathi e-inverter, konke kufinyelela okungenani ku-84,000, ngakho-ke. uma amathuba okuhluleka engu-1 kwabangu-10,000, kukhona angu-8, ngakho-ke amathuba okuba kwenzeke aphakeme kakhulu.

Ungayigwema kanjani i-DC Arc ku-Photovoltaic Power Station?

Okokuqala, qiniseka ukuthi usebenzisa imikhiqizo evamile futhi efanelekayo, hhayi imikhiqizo yomgunyathi nengenangqondo.NjengeSlocable'smc4 isixhumi se-fuse esisemgqenifuthiibhokisi lokuhlangana elihlukanisayo.
Okwesibili, inani lama-node kufanele lincishiswe ngangokunokwenzeka.
Okwesithathu, izisebenzi zokwakha kufanele zisebenzise amathuluzi aqeqeshiwe futhi kufanele ziqeqeshwe futhi zifaneleke ngokuqeqeshelwa umsebenzi kanye nokuhlolwa ngaphambi kokuba zifakwe emsebenzini.
Okwesine, ngemva kokufakwa kwesiteshi sikagesi, ukuhlolwa okufanele kwenziwe.
Okwesihlanu, kufanele kube namathuluzi okuthola ahambisanayo, njengale nzwa yokutholwa kwe-arc ye-DC, azohlaba umkhosi futhi anqamule umjikelezo uma esethole i-DC arc ukuze asuse izingozi ezifihliwe.
Okwesithupha, kufanele kube nenkundla yokuqapha amandla ukuze kuqashwe yonke idatha yokusebenza ngesikhathi sangempela, ukuze kuthi uma sekutholakele izingozi ezifihliwe, izisebenzi zaziswe ngokushesha ukuze zibhekane nazo.

Eqinisweni, i-DC arc ayibi.Uma nje ukwazi indlela efanele futhi usebenzisa izindlela zokuphikisa zesayensi, ungakwazi ukuvimbela ngempumelelo futhi ubhekane nakho.Njengamandla e-AC ekhaya, ukuphepha kuqinisekisiwe ngokuphelele.Ngezindlela zobuchwepheshe ezifanele, inkinga yokuvimbela nokulawula i-arc DC ingaxazululwa ngezindleko eziphansi.
