Lingaliro lonse

Kuti tikwaniritse bwino ntchito yamagetsi yamagetsi ya photovoltaic (PV), ngakhale yaying'ono, yoyikika padenga la nyumba yayikulu kapena yayikulu, yomwe ikufalikira kudera lalikulu, ndikofunikira kukhazikitsa ntchito yovuta. Ntchitoyi ikuphatikiza kusankha koyenera kwa mapanelo a PV ndi zina monga makina, mawonekedwe oyenera a zingwe (malo oyenera azinthu, kuwongolera koyenera kwa kulumikizana, kulumikizana kwachitetezo kapena chitetezo cha netiweki) komanso chitetezo chakunja ndi chakunja motsutsana ndi mphezi ndi kuphulika. Kampani ya LSP imapereka zida zotetezera (SPD), zomwe zitha kuteteza ndalama zanu pamtengo wotsika mtengo wogula. Musanawonetse zida zodzitchinjiriza, ndikofunikira kuti muzolowere magawo ena a photovoltaic ndi kulumikizana kwawo. Izi zimapereka chidziwitso chofunikira pakusankha SPD. Zimakhudza mphamvu yayikulu yotseguka ya gulu la PV kapena chingwe (unyolo wamapangidwe olumikizidwa motsatana). Kulumikizana kwa mapanelo a PV angapo kumawonjezera mphamvu yonse ya DC, yomwe imasandulika kukhala yamagetsi a AC mu ma inverters. Ntchito zokulirapo zimatha kufikira 1000 V DC. Kutseguka kotseguka kwa gulu la PV kumatsimikizika ndi mphamvu ya kunyezimira kwa dzuwa komwe kumagwera pama cell am'magulu ndi kutentha. Imatuluka ndi cheza chokulira, koma imagwa ndi kutentha kotentha.

Chinthu china chofunikira chimaphatikizapo kugwiritsa ntchito njira yoteteza mphezi yakunja - ndodo ya mphezi. Muyeso wa CSN EN 62305 ed.2 pa Chitetezo ku mphezi, Gawo 1 mpaka 4 limatanthauzira mitundu ya zotayika, zoopsa, njira zoteteza mphezi, milingo yoteteza mphezi komanso mtunda wokwanira. Magulu anayi otetezera mphezi (I mpaka IV) amadziwika magawo amomwe mphezi zimayendera ndipo kutsimikiza kumaperekedwa ndi kuchuluka kwa ngozi.

Momwemo, pali zochitika ziwiri. Pachiyambi, chitetezo cha chinthu ndi mawonekedwe akunja oteteza mphezi amafunsidwa, koma mtunda wokwera (kutanthauza mtunda pakati pa netiweki yochotsa mpweya ndi dongosolo la PV) sungasungidwe. Pansi pazikhalidwezi, ndikofunikira kuonetsetsa kulumikizana kwa galvanic pakati pa netiweki yothetsera mpweya ndi mawonekedwe othandizira mapanelo a PV kapena mafelemu a PV. Mphezi zikutulutsa ine_Ndondocha (kukakamiza pakadali pano ndi gawo la 10/350 μs) amatha kulowa m'mabwalo a DC; Chifukwa chake ndikofunikira kukhazikitsa mtundu wachitetezo cha 1. LSP imapereka yankho loyenera kwambiri mwazida zophatikizira 1 + 2 zamagetsi zotetezera FLP7-PV, zomwe zimapangidwira voliyumu ya 600 V, 800 V ndi 1000 V yokhala ndi kapena yopanda chizindikiro. Pachifukwa chachiwiri, palibe kufunika kokonzekeretsa chinthu chotetezedwa ndi njira yotetezera mphezi, kapena mtunda wokwera ukhoza kusungidwa. Poterepa, mphezi sizingalowe mu dera la DC ndipo zimangowonjezera kuphulika komwe kumaganiziridwa (zomwe zikuchitika pakadali pano ndi gawo la 8/20 μs), pomwe chida chodzitchinjiriza cha 2 ndichokwanira, mwachitsanzo mndandanda wa SLP40-PV, womwe umapangidwa pama voliyumu a 600 V, 800 V, ndi 1000 V, komanso popanda kapena kuwongolera kwakutali.

Pogwiritsa ntchito zida zodzitetezera, tiyenera kuganizira mbali ya AC komanso njira yolumikizirana, yomwe imagwiritsidwa ntchito popanga magetsi amakono a PV. Malo opangira magetsi a PV awopsezedwanso kuchokera kumbali ya netiweki ya DC (yogawa). Mbali iyi, kusankha SPD yoyenera ndikokulirapo ndipo zimadalira pulogalamu yomwe yapatsidwa. Monga woteteza padziko lonse lapansi, tikupangira chida chamakono cha FLP25GR, chomwe chimaphatikizapo mitundu itatu yonse ya 1 + 2 + 3 mkati mwa mita zisanu kuchokera pomwe adaikapo. Imakhala ndi ma varistor ophatikizana ndi omanga mphezi. LSP imapereka zida zingapo zodzitetezera pakuyesa ndi kuwongolera machitidwe komanso mizere yosamutsa deta. Mitundu yatsopano ya ma inverters nthawi zambiri amakhala ndi maupangiri omwe amalola kuwunikira makina onse. Zogulitsazo zimaphatikizapo mitundu ingapo yolumikizira ndi ma voltages osiyanasiyana amitundu yosiyanasiyana komanso kuchuluka kwa mitundu iwiri. Mwachitsanzo, titha kulangiza DIN Rail wokwera ma SPDs FLD2 mndandanda kapena woteteza woteteza PoE ND CAT-6A / EA.

Talingalirani zitsanzo zotsatirazi za ntchito zitatu zoyambira: siteshoni yaying'ono yamagetsi ya PV padenga la nyumba yabanja, siteshoni yapakatikati yayitali padenga la nyumba yoyang'anira kapena yamafakitale komanso paki yayikulu yoyendera dzuwa yomwe ikukhala pamalo akulu.

Nyumba ya banja

Monga tafotokozera pamalingaliro azida zotetezera ma PV, kusankha kwa mtundu winawake wamagetsi kumakhudzidwa ndi zinthu zambiri. Zogulitsa zonse za LSP zama pV zimasinthidwa kukhala DC 600 V, 800 V ndi 1000 V. Mphamvu yamagetsi imasankhidwa nthawi zonse kutengera mphamvu yayikulu yotseguka yoyendetsedwa ndi wopanga potengera dongosolo la mapanelo a PV okhala ndi ca 15 % amasunga. Panyumba yabanja - malo opangira magetsi aang'ono a PV, timalimbikitsa zopangidwa ndi gulu la FLP7-PV kumbali ya DC (pokhapokha nyumbayo isatetezedwe kunja kwa mphezi kapena mtunda wopita pakati pa netiweki yochotsa mpweya ndi PV dongosolo limasungidwa), kapena mndandanda wa SLP40-PV (ngati netiweki yochotsa mpweya imayikidwa patali mofupikirapo kuposa mtunda wopingasa). Popeza gawo la FLP7-PV ndi chida chophatikizira cha 1 + 2 (kuteteza onse motsutsana ndi mafunde amagetsi pang'ono komanso kuphulika) ndipo kusiyana kwamitengo sikabwino, izi zitha kugwiritsidwa ntchito pazosankha zonse ziwiri, potero zingabweretse zolakwika za anthu ngati ntchitoyi ili osawonetsedwa kwathunthu.

Kumbali ya AC, tikupangira kugwiritsa ntchito chida cha FLP12,5 chazogawika zazikulu mnyumbayi. Amapangidwa mu mtundu wokhazikika ndi wosinthika wa FLP12,5. Ngati inverter ili pafupi kwambiri ndi wofalitsa wamkulu, mbali ya AC imatetezedwa ndi chida chodzitetezera cha wofalitsa wamkulu. Ngati ili mwachitsanzo pansi pa denga la nyumbayo, ndikofunikira kubwereza kuyika kwa mtundu wa 2 chipangizo chodzitchinjiriza, mwachitsanzo SLP40 mndandanda (wobwezerezedwanso kapena wosinthika) mu sub-distributor yomwe nthawi zambiri imakhala pafupi ndi osintha. Timapereka mitundu yonse yomwe yatchulidwa ya zida zotetezera ma DC ndi ma AC pamayendedwe akutali. Pazambiri komanso kulumikizana, tikupangira kuti kuyika kwa DIN njanji yokhazikitsidwa ndi FLD2 yoteteza chitetezo chothana ndi screw.

Zoyang'anira ndi zomanga nyumba

Malamulo oyambira pazida zodzitetezera amagwiranso ntchito pulogalamuyi. Ngati tinyalanyaza magetsi, chinthu chofunikira kwambiri ndikupanganso njira yolumikizira mpweya. Nyumba iliyonse yoyang'anira kapena mafakitale nthawi zambiri iyenera kukhala ndi zida zotetezera zakunja. Momwemo, chomera chamagetsi cha PV chimaikidwa m'malo otetezera kutetezedwa ndi mphezi zakunja komanso mtunda wocheperako pakati pa maukonde othamangitsa mpweya ndi dongosolo la PV (pakati pamapangidwe enieni kapena magulu awo othandizira) amasungidwa. Ngati mtunda wapaulendo wothamangitsa mpweya ndi waukulu kuposa mtunda wopingasa, titha kungoganizira momwe zingayambitsire mpweya ndikukhazikitsa chida chodzitchinjiriza cha 2, mwachitsanzo SLP40-PV mndandanda. Komabe, tikulimbikitsabe kukhazikitsa zida zophatikizira 1 + 2 zamagetsi, zomwe zimatha kuteteza motsutsana ndi mafunde amphezi komanso kuphulika komwe kungachitike. Chimodzi mwazida zotetezerazi ndi SLP40-PV unit, yomwe imadziwika ndi gawo lomwe limasinthidwa koma limatha kusiyanitsa pang'ono kuposa FLP7-PV, yomwe imatha kupatutsa ena ndipo potero imakhala yoyenera kugwiritsa ntchito. Ngati mtunda wocheperako sungasungidwe, ndikofunikira kuwonetsetsa kulumikizana kokwanira pakati pazigawo zonse za PV ndikutetezedwa ndi mphezi. Zida zonse zotetezera izi zimayikidwa m'magawo omwe amagawira mbali ya DC chisanafike polowera. Pakakhala pulogalamu yayikulu pomwe zingwe ndizotalika kapena ngati makina oyikirira agwiritsidwa ntchito, ndibwino kubwereza chitetezo chazida ngakhale m'malo awa.
