Makampani a PV ali ndi mawu akuti: 2018 ndi chaka choyamba cha chomera chomwe chimagawidwa. Chilangochi chidatsimikiziridwa m'munda wa Photovoltaic Photovoltaic Box 2018 Nanang adagawa Phopvultaic Technology maphunziro aukadaulo! Okhazikitsa ndi ogulitsa kudutsa dzikolo adakumana nalo nanja kuti aphunzire mwadongosolo chidziwitso chofotokoza za Phopvoltaic.
Monga katswiri pamunda wa olumikizana, Renac akhala akudzipereka nthawi zonse ku Phocvovoltaic Science. Patsamba la maphunziro a Nanj, Renacsicasicasicasicasicasicasicasicasicasicasicasicasicasicasicasication adayitanidwa kuti agawane ndi ma tyvert ogwirizana ndi anzeru. Pambuyo pa kalasi, ophunzirawo adathandizidwa kupenda zovuta zomwe zimapangitsa kuti pakhale chithunzithunzi a Photovoltac ndipo adayamika mosadziwika kuchokera kwa ophunzira.
Malangizo:
1. Screen Screen sanawonekere
Kusanthula Kulephera:
Popanda DC
Zoyambitsa Zotheka:
. Voliyumu yazinthu zikugwirizana ndi zotupa za dzuwa.
(2) Ma terminal a PV amasinthidwa. Ma terminal pv ali ndi mitengo iwiri, yabwino komanso yoyipa, ndipo ayenera kufanana. Satha kulumikizidwa mobwerezabwereza ndi magulu ena.
(3) switch ya DC siitseka.
(4) Chingwe chikalumikizidwa chofanana, chimodzi mwa zolumikizira sichimalumikizidwa.
(5) Pali gawo lalifupi mu gawo, osagwiritsa ntchito zingwe zina pantchito.
Yankho:
Yerekezerani magetsi a DC ya infper ya omwe ali ndi mphamvu yamagetsi yamphamvu. Mphamvu ikakhala yachibadwa, voliyumu yonseyo ndi kuchuluka kwa magetsi a chinthu chilichonse. Ngati kulibe magetsi, ndiye yang'anani switch, terminal block, chingwe cholumikizira, ndi zigawo zikuluzikulu; Ngati pali zigawo zingapo, kulumikizana koyesedwa.
Ngati wolowetsa amagwiritsidwa ntchito kwakanthawi ndipo palibe chifukwa chakunja chimapezeka, madera a Harverter atlecle ali olakwika. Lumikizanani ndi injiniya wogulitsa pambuyo-testicle.
2. Wolowetsa salumikizidwa ndi netiweki
Kusanthula Kulephera:
Palibe kulumikizana pakati pa wolowetsa ndi gululi.
Zoyambitsa Zotheka:
(1) Kusintha kwa AC sikutsekedwa.
(2) Kutulutsa kwa acs kwa acs sikulumikizidwe.
.
Yankho:
Yerekezerani magetsi omwe ali ndi vuto la AC ndi voliyumu yamagetsi yamphamvu. Munthawi zonse, mawu otulutsa ayenera kukhala ndi 220V kapena 380v mafuta. Ngati sichoncho, onani ngati kulumikizidwa, ngati kusintha kwa ac kumatsekedwa, ndipo ngati kusintha kokhazikika kumasokonekera.
3. Inverter PV Overvoltage
Kusanthula Kulephera:
DC Vomboge yayikulu kwambiri.
Zoyambitsa Zotheka:
Chiwerengero chochuluka cha zigawo zina chimayambitsa voliyumu kuti ipitirire malire mphamvu yamagetsi yolowera.
Yankho:
Chifukwa cha kutentha kwa zigawo zikuluzikulu, kutsitsa kutentha, mphamvu yamphamvu. Magetsi ophatikizika a chingwe cholumikizira cha gawo limodzi ndi 50-600v, ndi zingwe zolumikizira zingwe zili pakati pa 350-400. Mitundu yamagetsi yamagetsi ya gawo la magawo atatu ndi 200-1000v. Mitundu yamagetsi yotumiza ili pakati pa 550-700v. Mu mphamvu yamagetsi iyi, mphamvu ya yolowetsa ndiyokwera kwambiri. Ma radiation akakhala otsika m'mawa ndi madzulo, amatha kupanga magetsi, koma sizimayambitsa magetsi kuti isapitirire malire a mphamvu ya otchinga, ndikupangitsa alamu ndi kuyimitsa.
4.. Natcheru otchinga
Kusanthula Kulephera:
Kukaniza kwa zisonyezo za Photovoltaic dongosolo mpaka 2 megohms.
Zoyambitsa Zotheka:
Ma module a dzuwa, mabokosi am'madzi, mabokosi a DC, zingwe, zingwe zazifupi, zotupa, ndi zina zowonongeka mpaka kukhazikika. Matumba a PV ndi nyumba yokhomera imasiyidwa, yomwe imapangitsa impso.
Yankho:
Sanjani gululi, lowani, onani kukana kwa chinthu chilichonse pansi, dziwani kuti mavutowo, ndipo m'malo mwake.
5. Kulakwitsa kwakukulu
Kusanthula Kulephera:
Mphamvu yamagetsi yosiyanasiyana komanso pafupipafupi kapena okwera kwambiri.
Zoyambitsa Zotheka:
M'madera ena, intaneti ya kumidzi sinapangidwenso ndipo voliyumu ya Gridi siyikungokhala mkati mwa malamulo otetezeka.
Yankho:
Gwiritsani ntchito mankhwala opindika mphamvu yazigawo komanso pafupipafupi, ngati sichoncho podikira gululi kuti mubwererenso bwino. Ngati mphamvu ya Grid ndi yabwinobwino, ndi yomwe imazindikira kulephera kwa gulu la madera. Sinthani ma temple onse a DC ndi ma ac a makinawo ndikulola kuti mutuwo ubwere kwa pafupifupi mphindi 5. Tsekani magetsi. Ngati itha kuyambiranso, ngati singathe kubwezeretsedwa, kulumikizana. Injiniya wogulitsa masinja.
