Masiku ano, ena ku Ulaya akuda nkhawa ndi kukwera kwa mitengo yamagetsi, ndipo ngakhale mantha onse okhudzana ndi izi atayika usiku umodzi, ndithudi tidzawona kuwonjezeka kwa mitengo. Monga owononga, mutha kuyang'ana bwino zida zomwe zili ndi njala m'nyumba mwanu ndipo ngakhale kuchitapo kanthu. Chifukwa chake, [Peter] adayika ma sola padenga lake, koma sanathe kudziwa momwe angalumikizire mwalamulo ku gridi ya anthu, kapenanso ma mainji a 220V mnyumba mwake. Zachidziwikire, yankho labwino ndikumanga maukonde osiyana a LVDC ndikuyika zida zambiri pamenepo!
Anasankha 48V chifukwa ndi yokwera mokwanira, yothandiza, yosavuta kupeza zinthu ngati DC-DC, yotetezeka pankhani yazamalamulo, ndipo nthawi zambiri imagwirizana ndi khwekhwe lake la solar. Kuyambira pamenepo, amasunga zida monga ma laputopu, ma charger, ndi magetsi panjanji zamagetsi za DC m'malo mozilowetsa mwachindunji, ndipo zomanga zake zapanyumba (kuphatikiza rack yodzaza ndi ma Raspberry Pi board) ndizokwanira kugwira ntchito 24/7. njanji 48V. Pali mphamvu yosungira yochokera kumagetsi anthawi zonse a AC pakagwa mitambo, ndipo ngati magetsi azimitsidwa, mabatire akuluakulu awiri a LiFePO4 adzapatsa mphamvu zida zonse zolumikizidwa pa 48V mpaka masiku awiri ndi theka.
Chipangizocho chinapangidwa ndi kuwononga 115 kWh m'miyezi iwiri yoyambirira - chothandizira chachikulu ku polojekiti yodziyimira pawokha yodziyimira payokha, ndipo positi ya blog ili ndi tsatanetsatane wokwanira pazosowa zanu zonse zowuziridwa. Pulojekitiyi ndi chikumbutso kuti mapulojekiti otsika kwambiri a DC ndi njira yabwino pamlingo wamba - tawona mapulojekiti oyendetsa bwino ku Hackcamp, koma mutha kupanganso DC UPS yaying'ono ngati mukufuna. Mwina posachedwa tipeza njira yopezera maukonde oterowo.
Malo opangira ma cell akugwiritsa ntchito 48V. Ndiyenera kukhazikitsa china chofanana ndi polojekiti yoyang'anira anthu oyandikana nawo.
Ndinali kuganiza zoyendetsa ma seva a HP DL360 kunyumba ndi ma solar panels ndi mabatire opanda magetsi a 48VDC omwe angagwirizane ndi masevawa ndikupewa kusachita bwino kwa inverter ya DC-to-AC, koma ndinawona mtengo wamagetsi awa pa 48. VDC. … MULUNGU WANGA. Bweretsani ndalama mpaka 2050!
48V yakhala mphamvu yamabasi pamakina olumikizirana matelefoni kuyambira nthawi ya Strowger (yokhala ndi mabatire akulu) ndikupitilira mu zida za fiber optic network.
Inde, makampani onse a telecom amayendera 48VDC. Kuchokera pa masinthidwe akale a analogi kupita ku masiteshoni amakono a ma cell. Ma data a IT nthawi zambiri amathandizidwa ndi mphamvu ya AC.
ZABWINO Chokhachokha ndi kukhazikitsidwa kumeneku (poganiza kuti theka lina likuvomerezedwa ndikusungidwa pamalo otetezeka kutali ndi ziweto ndi ana) ndikuti pamene malo osungirako mphamvu a m'deralo ali odzaza, mphamvu zowonjezera zimawonongeka pamene muli pafupi ndi gridi. ma interconnects akupita, mwina ndizochititsa manyazi kuti mphamvuzo zimagwiritsidwa ntchito pa zotsika mtengo. Sindikuwaimba mlandu chifukwa cha izi, adzipangira okha ntchito ndipo sapeza njira yovomerezeka, yotetezeka / yotsika mtengo pazovuta zomalizazi…mabungwe ali bwino kuposa maloya ndi andale. ngakhale nthawi zambiri amafanana m'moyo, mwina onse ndi osiyana amtundu womwewo ...
Ndinganene kuti moyo ukhale wosavuta kwa anthu omwe si aukadaulo omwe ali ndi DC mutha kukhala nawo kapena kuthandizira njira yabwino kwambiri yomwe ilipo masiku ano yomwe mwina ili ndi USB… zikuwoneka ngati vuto lalikulu, ndipo sizowoneka bwino ngati njanji ya 48V. Zili ponseponse kotero kuti zimamveka kwa anthu omwe si aukadaulo - chifukwa ndi zomangika ndipo zimagwira ntchito (ngati zikonzedwa moyenera). Chotsani kufunikira kopeza chosinthira choyenera cha DC-DC pachilichonse kapena kuyang'anira mphamvu ya "magetsi" nthawi zonse mukalumikiza chipangizo chatsopano - ndimachita izi pa desiki langa koma sindinakazinge chilichonse…
Koma monga paketi ya batire ya alumali yokhala ndi zowunikira zowunikira dzuwa, mwinanso ngati chosinthira pa paketi ya AC muyenera kukhala nacho, ndipo ngati mukufuna kupewa kupanga magetsi anu omwe amakwiyitsa kwambiri a USB, mutha kugwiritsa ntchito chinthu choyankhulirana cha USB. . Sizovuta kwambiri kuti muyike. Komanso, ndizokwanira kuti ma hackers pakati pathu akhazikitse ma solar panels (makamaka pazitsulo zoyang'anira dzuwa), kupereka zowunikira, zidziwitso za batri yotsika, ndi kukonza zingwe mwaukhondo pamalo amodzi ofunikira kwambiri pantchito zachinyengo. Pang'ono…
Njira yabwino yothetsera mphamvu zochulukirapo ndikutaya katundu monga zida zamagetsi mu chotenthetsera chamadzi. Battery ikangotha kuchangidwa, imatha kusintha kugwiritsa ntchito mphamvu yadzuwa yomwe ilipo kuti itenthetse madzi.
Ngakhale kutentha kwa madzi kungathenso "kudzaza" (kutentha mokwanira) pakapita nthawi, pokhapokha ngati kuli kwakukulu kwambiri.
Ubwino wa mphamvu ya dzuwa ndikuti simusowa kusonkhanitsa mphamvu za dzuwa. Mutha kuyika mapanelo pansi padzuwa popanda kugwiritsa ntchito mphamvu.
Zoonadi, izi ndizowonongeka, ndipo ngati ndizopindulitsa, kudyetsa mphamvu ku gridi ndiko kusankha koyamba.
Monga CityZen imati, idzadzaza pakapita nthawi, ndi njira ina yosungira mphamvu. Osanenanso, ngati mukukhala kale kumalo otentha, chowongolera mpweya wanu chidzagwira ntchito molimbika ngati muli nacho, ndipo ngati sichoncho, moyo wanu udzakhala wosasangalatsa kuposa momwe umayenera kukhalira, chifukwa thanki ndi insulated basi… sitolo yabwino kwambiri yamagetsi, koma nyumba zambiri sizifuna madzi otentha kwambiri, ndipo khwekhwe lalikulu la thanki limodzi limatanthauza kuti pamene mulibe mphamvu zaulere, mumakhalabe ndi madzi ambiri oti mugwiritse ntchito mokwanira. kutenthetsa chifukwa cha malo akuluakulu omwe amachititsa.
Palibe kwenikweni "kutsitsa" kwabwino pamlingo wamunthu, maukonde akulu okhala ndi mbewu zazikulu amatha kuyendetsa mosavuta masinthidwe owonjezera pang'ono ndikuwonjezera kupanga kupitilira kufunikira kuti agwiritse ntchito bwino mphamvu "zaulere". Koma panokha, ndi chifukwa chongokhalira kusewera mokweza ndi rock 24/7, kugwiritsa ntchito mphamvu mosasamala nthawi yayitali kapena mpaka mnansi wanu atakuphani.
Komabe, nyengo yotentha kapena yotentha, kuziziritsa kwa mayamwidwe kungathandize kugwiritsa ntchito kutentha kwakukulu kuziziritsa zipinda.
Mukhozanso kuyendetsa kanyumba kakang'ono ka air conditioner ndi inverter ngati muli ndi mphamvu zambiri zowonjezera kuti muzimitse ndikutentha. Mwina inverter ili panja… Zingakhale zosangalatsa kwambiri kuwona ngati mutha kupanga pampu yotentha yomwe imagwiritsa ntchito mpweya wakunja ngati gwero la kutentha/radiator. Zedi, ndizosakwanira, koma ngati vuto lanu lili ndi mphamvu zambiri, kusachita bwino kungathandize.
@smellsofbikes Chifukwa chakuti nthawi zina mumakhala ndi mphamvu zambiri ndipo mutha kupanga china chake mopanda ntchito sizikutanthauza kuti muyenera kuchita. Kodi chimachitika ndi chiyani mukakhala kuti mulibe mphamvu pakali pano koma mukuyenera kudutsa njira yosakwanira? Monga chitsanzo changa chachikulu cha thanki yamadzi pamwambapa, muyenera kupeza njira yoyenera kuti mukakhala opanda mphamvu komanso mukakhala ndi mphamvu zokwanira zochitira konsati ya heavy metal, zinthu zofunika/zothandiza zitha kutha… . ..
Pamene simungathe kupereka ndalama kapena bwanji osapereka kwaulere **? Ndiye zowonjezera zonse zomwe mungapange ndizothekera zomwe simukuzigwiritsa ntchito, ndipo simathero adziko lapansi, zamanyazi chabe.
** Pongoganiza kuti izi sizikufuna kuti mupange ndalama zogulira - yomwe ili vuto lalikulu pano, "ndalama zotsika" zolumikizira netiweki ndizofunika, kotero ngakhale simugwiritsa ntchito zambiri zolumikizira zanu mwina zingawononge ndalama. Zambiri . kuposa momwe amakutumizirani. Amakulipirani mochulukira - osati kuti ndikuletsa kupereka mochulukira, zimagwira ntchito kwa anthu ena mu network yayikuluyi ndipo sindikufuna. Koma kulipira kampani yochuluka kwambiri kuti ikhale ndi mwayi wopanga ndalama zambiri kuchokera kwa anthu ena…
Pamene zida zoyendetsedwa ndi USB zimachulukirachulukira, ndidaganiza zofananira ndi 5V. Zabwinonso zitha kukhala madoko angapo a 5V USB C ndi madoko angapo a AC. Kuchokera pamenepo, mutha kugwiritsa ntchito 5V pazida zotsika mphamvu ndi USB C pazida zamphamvu kwambiri. Choyipa ndichakuti madoko a USB C amayenera kuyendetsa magetsi pa doko pomwe USB A 5v ndi njanji ya 5v basi.
Osachepera, ndili wotsimikiza kuti ndikamaliza kumanga ofesi yokhala ndi ma mains a 5V USB. Ndikanachitanso 12V, popeza mapulojekiti anga apakompyuta omwe amafunikira kupitilira 5V pafupifupi nthawi zonse amafuna 12V. (Komanso, ndikutsimikiza kuti rauta iliyonse yomwe ndili nayo imagwiritsa ntchito 12V, ndipo zingakhale bwino kukhala ndi malo osavuta pachipangizo chilichonse m'malo mwa chosinthira khoma!)
Pepani kukuuzani kuti 5V (kapena 12V) ndiyabwino kugawa mphamvu: mita imodzi kapena ziwiri za chingwe chokoka chotayika 10% kapena kupitilira apo ndizosatheka kugwiritsa ntchito. Magalimoto amalimbana ndi 12v nthawi zonse, koma popeza ndi ang'onoang'ono amatha kuthana nawo, koma magalimoto ndi mabwato akuluakulu amagwiritsa ntchito 24v, kotero inde, 48v ndiye mtengo wabwino kwambiri: akadali otetezedwa malinga ngati simukunyengerera. . magetsi okhazikika, zida zokwanira komanso kutha kunyamula utali wina wake popanda kutaya kwambiri.
Kuwonongeka kwa kusintha kwa mphamvu ndikofunikira kwambiri kuposa kutayika kwa chingwe. Mwachitsanzo, pankhani ya nkhaniyi, poganiza kuti kutembenuka kulikonse kwa DC-to-DC ndi 90% kothandiza, timatha kutaya 27% ya mphamvu yomwe timapeza kuchokera ku 5V USB charger. Ngati wotembenuzayo ndi woipa pang'ono, ndi 85%, ndiye kuti zotayika zidzafika 39%. Owongolera ma charger ndi ma converter pochita bwino amakwanitsa pafupifupi 80%, kotero sizachilendo kutaya theka la mphamvu pakungowongolera magetsi. Ngati kufunikira kwa dongosolo kuli kochepa, kuwonongeka kwa zida zopanda ntchito kumatha kuwononga pafupifupi mphamvu zonse.
Pokhapokha mutagwiritsa ntchito zingwe zokhuthala, kutayika kwa chingwe kumatha kukhala kokwera kwambiri pa 5V, ndipo mutha kugwiritsa ntchito zambiri pazingwezi kuposa momwe mungasinthire bwino 24V.
Ngati muli ndi madoko awiri a 5W USB, mufunika magetsi a 120W. Ngati magetsi anali ndi katundu wokhazikika wa 10W, "kuchita bwino" pa katundu wotchulidwawo kukanakhala 92%, koma pamene magwiritsidwe ntchito a doko la USB ali pafupifupi 5%, mphamvu yeniyeni yonseyi imakhala pafupifupi 60%. .
Chilichonse chomwe chili pansi pa 36V sichiyenera kugwiritsidwa ntchito pamtunda wautali. Makamaka osati 5v. Ma adapter amagetsi ndi otsika mtengo, mkuwa ndi wokwera mtengo komanso wolemera. Mabatirenso ndi okwera mtengo ndipo kutayika kwa magetsi ndi vuto.
Payekha, sindikanapanga mtundu uliwonse wa LVDC microgrid konse (Ndinkakonda kusewera nawo ndikudana nawo kwambiri ndinapanga kanema wathunthu za izo).
Nthawi zonse ndimanena kuti ikani batri pamalo odzaza ndikugwiritsa ntchito chingwe chowonjezera ngati mukufuna mphamvu. Kupatulapo ndi PoE, yomwe ili yaulere pa Ethernet ndipo mutha kuyifuna pazifukwa zina.
USB-C yama projekiti anu onse, yoyendetsedwa ndi mabatire akunja ndi ma adapter apakhoma ngati pakufunika. Dziwani kuti ma module oyambitsa USB-PD alipo, mutha kupeza 9, 15 kapena 20 ngati mukufuna (12V ndi yachikale ndipo mwina sangagwire ntchito ndi ma adapter atsopano a IIRC)
Ngati mukufuna kugwiritsa ntchito mphamvu ya dzuwa, 12V ndi yabwino kwa ang'onoang'ono amathamanga mpaka 100W kwa mapazi pang'ono, komanso ndizofala kwambiri kuposa 5V ndi 48V etc, pitani. Kapena ingogulani jenereta ya dzuwa ya LifePO4, ndizosangalatsa.
Aliyense amene akufuna kuchita-izo-yourselfer nthawi zonse amafuna kuchita zina ndi basi ya DC, koma nthawi zambiri zimakhala zoipa chifukwa zida za ogula sizimapangidwira ndipo mumataya "ntchito" ya njere ya USB yomwe imathera ponseponse. malo. Ndi zingwe zazikulu komanso gulu la zolumikizira zomwe sizikugwirizana ndi dziko lonse lapansi ndipo zimangovutitsa makina anu a DIY.
Kukhazikitsa kwabwino komwe ndawonapo ndi mulingo wa ARES wa wailesi ya ham, koma ngakhale pamenepo… ndizabwino pakuthamanga kwakanthawi kochepa.
Kwa mphamvu ya 5V muofesi, ndimangogwiritsa ntchito khoma lomwe lili ndi thiransifoma yomangidwa ndi doko la USB.
Pakuti 12V kwa routers ndi zinthu zina kuti athetse, ine ndikanangogula lalikulu 12V 5A thiransifoma ndi 2.1mm Y-chingwe (onetsetsani kuti mumapeza abwino) kapena dikirani mpaka choyambitsa gawo lilipo PPS kwa 12V, kutenga 12V. USB kuchokera ku zida zatsopano - doko C.
Kapena bwinobe, chotsani mphamvu zomwe si za USB ngati n'kotheka. Kuwononga pang'ono pakukweza kuti mutenge ma USB-PD onse kumathetsa vuto lonse mukafuna rauta yatsopano kapena rauta iliyonse yapamwamba yomwe ingakhale yoyendetsedwa ndi USB.
Ndikadafunadi chotulutsa cha 12V, ndikadaganiza zoyika chosinthira chachingwe cha Mean Well mubokosi lautumiki pafupi ndi malo ogulitsira m'malo mogwiritsa ntchito 12V. Palibe nsonga imodzi yolephera, kutaya mphamvu mu chingwe chokhuthala kapena chowonda, kukonza kosavuta komanso koonekeratu.
120V DC ndiyabwino kupatsa mphamvu magwero ambiri a "AC", koma ndiye malire otsika kwambiri omwe amasangalala nawo. Amakonda 160VDC kapena kupitilira apo.
Ayi, muzochitika zanga adadula mozungulira 65Vdc, koma muyeneranso kuchepetsa 130Vdc, sindinayesedwe, koma ndikuganiza kuti kutsika kwa 100-0% kuchokera ku 130-65Vdc.
Lingaliro lachilendo. Ndikuganiza kuti gawo lolowera likugwira ntchito yokhazikika. Izi zikutanthauza kuti magetsi akafika 130V mpaka 65V, mlingowo umachepetsedwa kufika 50%, ndipo pansi pa 65V, dera lina lotseketsa magetsi limayambitsidwa.
Malo ambiri ali ndi batire yomwe imathandizira ma relay otetezedwa ndikulola kuti oyendetsa madera azigwira ntchito (kutsegula ndi kulipiritsa) ngati magetsi akuzima. Mphamvu yamagetsi ndi 115 VDC. Imayendetsa 100% pa batri ndipo ili ndi AC-> DC chojambulira kuonetsetsa kuti batire imakhala yokwanira nthawi zonse, kotero palibe solar pankhaniyi.
Malinga ndi buku la Motzenbocker "Kubwezeretsa Mphamvu" https://yugeshima.com/diygrid/ 120vdc kokha
Vuto la kugawa magetsi kwa DC linathetsedwa mothandizidwa ndi 802.3af (aka PoE) - Mphamvu pa Ethernet. Palibe chifukwa chogwiritsa ntchito gawo la Ethernet la equation. Ma adapter opezeka paliponse, kugawa mphamvu zotetezedwa komanso zida zabwino zoperekera malipoti / kasamalidwe. Ndizosakwera mtengo ngakhale - mutha kupeza 100Mbps 48-port data center hub pamtengo wochepera $30.
Hotelo ya Marcel ku New Haven ili ndi zipinda 164, zonse zoyendetsedwa ndi magetsi a solar ndi mawaya a DC. Nayi chithunzithunzi chabwino: https://www.youtube.com/watch?v=J4aTcU6Fzoc.
Ndikanena, amagwiritsa ntchito POE. Zowonongeka zomwe zimachitika chifukwa cha opareshoni ziyenera kukhala zochepa poyerekeza ndi zotayika mukasintha kuchokera ku DC kupita ku AC ndikubwerera ku DC. Zimakupatsaninso ma analytics okhazikika pazomwe mukugwiritsa ntchito.
Nthawi zina ndimayiwala kuti ndimakhala popanda intaneti. Ndili ndi 48VDC kuti 220VAC inverter mu khwekhwe wanga amene amaika za 5kW mosalekeza, ngakhale kuti sichinayambe yodzaza kwambiri. Pampu yamadzi 220 volt, firiji, mufiriji, zida, zida, zowunikira, zonsezi ndizokhazikika pamadambo. Ndili ndi 12V yosiyana ndi 24V DC ndi/kapena mitundu ina yambiri yamagetsi. Pangani bizinesi yopangira zitsulo pamalo omwewo ndikupopera madzi akumwa a kavalo wamkulu. Mabatire amachokera ku dongosolo lalikulu la UPS lomwe ndimapeza ndikasintha mabatire pa ndandanda. Chitani mayeso amagetsi pamabatire, sankhani zabwino kwambiri, kenaka yikani chowotcha chokana, ndikuwunikanso mphamvu, sankhaninso zabwino kwambiri ndikuzigula.
Inde, zida zambiri zokhala ndi "Universal" AC zolowetsa zimatha kugwira ntchito pamagetsi a DC. Chulukitsani magetsi a AC ndi 1.4 kuti mutenge voteji ya DC yofanana. Komabe, ma fuse awo amkati samavotera DC. M'malo mwawo ndi fusesi ya DC kapena gwiritsani ntchito fuse yakunja. Osawotcha nyumba!
> "Izi zikutanthawuza kuti voteji yozungulira kwambiri ndi pafupifupi 0.80 V. Pakachitika moto (mwachiyembekezo sichidzatero), izi sizingakhale zoopsa kwambiri kwa ozimitsa moto."
Muyezo wa ELV umawona 120 VDC "otetezeka" popanda ripple, koma EU General Safety Standard imaika malire ku 75 VDC, pamene Low Voltage Directive imagwira ntchito pamagetsi aliwonse a 75-1000 VDC. Mukhozabe kuswa lamulo ndikusowa chilolezo kuti muyike kachitidwe kameneka, koma n'zovuta kupeza yankho lomveka bwino kapena zolemba zilizonse zomwe mungachite ngati womanga payekha popanda maphunziro apadera.
