Namhlanje, abanye eYurophu banexhala lokunyuka kwamaxabiso amandla, kwaye nokuba lonke uloyiko olunxulumene noku lunyamalale ngobusuku, ngokuqinisekileyo siya kubona ukunyuka kwamaxabiso. Njengomntu okhohlisayo, unokujonga kakuhle izixhobo ezilambele amandla kwikhaya lakho kwaye uthathe inyathelo kuzo. Ngoko ke, [uPetros] wafaka ezinye iiphaneli zelanga eluphahleni lwakhe, kodwa akazange akwazi ukufumanisa ukuba angaziqhagamshela njani ngokusemthethweni kwigridi kawonke-wonke, okanye ubuncinane kwii-220V ezinkulu zendlu yakhe. Ngokuqinisekileyo, isisombululo esihle kukwakha inethiwekhi ye-LVDC ehambelanayo kunye nokubeka iqela lezixhobo kuyo!
Wakhetha i-48V kuba iphezulu ngokwaneleyo, iyasebenza, kulula ukufumana izinto ezifana ne-DC-DC, ikhuselekile xa kuziwa kwimiba yomthetho, kwaye iyahambelana ngokubanzi kunye nokusekwa kwakhe kwepaneli yelanga. Ukusukela ngoko, uye wagcina izixhobo ezifana neelaptops, iitshaja, kunye nezibane kwiireyile zamandla zeDC kunokuba uzixhume ngokuthe ngqo, kunye neziseko zophuhliso lwasekhaya (kubandakanya irakhi egcwele iibhodi zeRaspberry Pi) ziqulathe ngokugqibeleleyo ukusebenza 24/7. uloliwe 48V. Kukho unikezelo lwamandla olugciniweyo olusuka kubonelelo lwamandla oluqhelekileyo lwe-AC kwimeko yemozulu yamafu, kwaye kwimeko yokucima kombane, iibhetri ezinkulu ezimbini zeLiFePO4 ziya kunika amandla zonke izixhobo eziqhagamshelweyo kwi-48V ukuya kuthi ga kwiintsuku ezimbini ezinesiqingatha.
Isixhobo sivelise kwaye sadla i-115 kWh kwiinyanga ezimbini zokuqala - igalelo elikhulu kwiprojekthi ye-hacker yokuzimela kwamandla, kwaye isithuba seblogi sineenkcukacha ezaneleyo kuzo zonke iimfuno zakho zokuphefumlelwa. Le projekthi sisikhumbuzo sokuba iiprojekthi zombane ophantsi wombane we-DC lukhetho olulungileyo kwisikali sasekhaya - sibonile iiprojekthi zokulinga ezisebenzayo eHackcamp, kodwa unokwakha i-DC UPS encinci ukuba uyathanda. Mhlawumbi kungekudala siza kufumana indawo yokuphuma kuthungelwano olunjalo.
Izikhululo zeSellula ngoku zisebenzisa i-48V. Kufuneka ndiseke into efanayo kwiprojekthi yokugada ebumelwaneni.
Ndandicinga ngokuqhuba ezinye iiseva ze-HP DL360 ekhaya kunye neepaneli zelanga kunye neebhetri ngaphandle kwe-48VDC izixhobo zombane eziza kulungelelaniswa nezi seva kwaye ziphephe ukungasebenzi kwe-DC-to-AC inverter, kodwa ndabona ixabiso lezi zinto zombane kwi-48. VDC. … THIXO WAM. Buyela kutyalo-mali kude kube ngu-2050!
I-48V ibingumbane webhasi kwiinkqubo zonxibelelwano ukusukela ngexesha likaStrowger (eneebhetri ezinkulu) kwaye igqithiselwe kwisixhobo sothungelwano lwefiber optic.
Ewe, lonke ishishini le-telecom lisebenza kwi-48VDC. Ukusuka kwizitshixo zakudala ze-analog ukuya kwizikhululo zeselfowuni zanamhlanje. Amaziko edatha ye-IT axhaswe ngamandla e-AC.
OKULUNGILEYO I-bummer kuphela ngolu cwangciso (ucinga ukuba esinye isiqingatha sivunyiwe kwaye sigcinwe kwindawo ekhuselekileyo kude nezilwanyana ezifuywayo kunye nabantwana) kukuba xa ugcino lwamandla lwendawo lugcwele, amandla angaphezulu ayachithwa xa usondele kule gridi. Unxibelelwano luyahamba, kulihlazo ngokwenene ukuba la mandla achithwa kwizinto ezitshiphu. Andibabeki tyala ngale meko, bazenzele umsebenzi kwaye abanakufumana indlela esemthethweni/ekhuselekileyo/efikelelekayo malunga nalo mqobo wokugqibela…abasemagunyeni baphila ngcono kunamagqwetha nabezopolitiko. nangona zihlala zifana ebomini, mhlawumbi onke angamazwe ahlukeneyo obomi obufanayo…
Ndingathi ukwenza ubomi bube lula kwaba bantu bangengabo ubuchwephesha abane-DC uya kuhlala nabo okanye uxhase eyona ndlela ingcono ekhoyo namhlanje enokuthi ixhaswe nge-USB… ibonakala ngathi yingxaki enkulu, kwaye ayinakwenzeka ukuba isebenze njengololiwe we-48V. Ixhaphake kakhulu kangangokuba iyaqondakala kubantu abangezochwephesha - kuba iplagi kwaye iyasebenza (ukuba iqwalaselwe ngokuchanekileyo). Cima isidingo sokufumana isiguquli esifanelekileyo se-DC-DC kuyo yonke into okanye ujonge ngamandla amandla ombane rhoqo xa uplaga isixhobo esitsha-ndikwenza oku kwidesika yam kodwa andikaqhotsi nto...
Kodwa njengepakethi yebhetri ekwishelufu enegalelo lokulandela umkhondo welanga, mhlawumbi njenge-inverter yepakethi ye-AC kufuneka ube nayo, kwaye ukuba ufuna ukunqanda ukwakha owakho umbane ocaphukisayo we-USB, ungasebenzisa into yothethathethwano lwamandla e-USB. . Akunzima kakhulu kuwe ukuseta. Kwakhona, kungaphezulu kokwaneleyo ukuba abahlaseli phakathi kwethu bafake iiphaneli zelanga (ngokukhethekileyo kwii-mounts zokulandela ilanga), babonelele ngeemonitha zesimo, izilumkiso zebhetri ephantsi, kwaye zilungelelanise kakuhle iintambo kwindawo enye ebalulekileyo yomsebenzi wobuqhophololo. Kancinci…
Isisombululo esilungileyo samandla agqithisileyo kukulahla imithwalo efana nezixhobo zombane kwisifudumezi-manzi. Yakube ibhetri igcwaliswe ngokupheleleyo, inokutshintshela ekusebenziseni amandla akhoyo elanga ukufudumeza amanzi.
Nangona isifudumezi samanzi sinokuphinda "sizalise" (ishushu ngokwaneleyo) ekuhambeni kwexesha, ngaphandle kokuba sikhulu kakhulu.
Inzuzo yamandla elanga kukuba akufuneki uqokelele amandla elanga. Ungabeka iipaneli ngokukhuselekileyo phantsi kwemitha yelanga ngaphandle kokusebenzisa amandla anokubakho.
Ngokuqinisekileyo, oku kuyinkunkuma, kwaye ukuba kukulungele wena, ukondla amandla kwigridi lukhetho lokuqala.
Njengoko iCityZen isitsho, iya kuzalisa ngokuhamba kwexesha, yenye nje indlela yokugcina amandla. Singasathethi ke, ukuba sele uhlala kwindawo eshushu, isipholile-moya sakho siya kusebenza nzima ngakumbi ukuba unayo, kwaye ukuba akunjalo, ubomi bakho buya kuba ngathandekiyo kunokuba bufanele ukuba bubenjalo, kuba itanki ifakwe i-insured kanye ... Amanzi ngokwenene ivenkile yamandla elunge kakhulu, kodwa uninzi lwamakhaya aluwafuni ngenene amanzi ashushu kangako, kwaye ukuseta itanki enkulu enye kuthetha ukuba xa ungenawo amandla asimahla, usenawo amanzi amaninzi wokuwasebenzisa ngokupheleleyo. ephezulu yokufudumeza ngenxa yommandla omkhulu womphezulu owubangelayo.
Ngokwenene akukho "ukukhuphela" okulungileyo kwisikali somntu ngamnye, inethiwekhi enkulu enezityalo ezinkulu inokuqhuba ngokulula iinguqu ezimbalwa ezongezelelweyo kunye nokwandisa imveliso ngaphaya kwemfuno ukwenza uninzi lwamandla "asimahla". Kodwa buqu, sisizathu nje sokudlala phezulu kunye ne-rock 24/7, ukusetyenziswa kwamandla ngokungakhathali ngelixa kuqhubeka okanye de ummelwane akubulale.
Nangona kunjalo, kwimozulu eshushu ukuya kushushu, ukupholisa ukufunxa kunokunceda ukusebenzisa ubushushu obugqithisileyo ukupholisa amagumbi.
Ungaqhuba negumbi elincinci lokupholisa umoya elinesiguquli ukuba unamandla amaninzi agqithisileyo okucima kwaye kushushu. Mhlawumbi i-inverter ingaphandle… Kuya kuba nomdla kakhulu ukubona ukuba ungenza impompo yobushushu esebenzisa umoya wangaphandle njengomthombo wobushushu/iradiator. Ngokuqinisekileyo, ayisebenzi kakuhle, kodwa ukuba ingxaki yakho inamandla kakhulu, ukungasebenzi kakuhle kuya kunceda.
@smellsofbikes Kungenxa yokuba ngamanye amaxesha unamandla amaninzi kwaye unokwakha into engafanelekanga akuthethi ukuba ufanele. Kwenzeka ntoni xa uphelelwa ngamandla ngoku kodwa kusafuneka uhambe kwinkqubo engasebenziyo? Njengomzekelo wam wetanki enkulu yamanzi apha ngasentla, kufuneka ufumane ibhalansi efanelekileyo ukuze xa uphelelwa ngamandla kwaye xa unamandla aneleyo ekonsathi yentsimbi enzima, izinto ezibalulekileyo/eziluncedo zinokugqitywa… . ..
Xa ungakwazi ukunika imali okanye kutheni unganiki simahla **? Emva koko konke ukugqithisa onokuthi udale yinto nje ongayisebenzisiyo, kwaye ayisosiphelo sehlabathi, ihlazo nje.
** Kucingelwa ukuba oku akufuni ukuba wenze naziphi na iindleko ezisebenzayo - eyona nto ingumba omkhulu apha, "intlawulo ethe tyaba" yoqhagamshelo lwenethiwekhi ibalulekile, ngoko ke nokuba awusebenzisi uninzi lonxibelelwano lwakho kuya kuba nexabiso. Kaninzi . kunokuba bayithumele kuwe. Bakuhlawulela u-excess – hayi ukuba ndichasene nokunikezela nge-excess, iyabasebenzela abanye abantu abakule nethiwekhi inkulu kwaye andiyidingi. Kodwa ukuhlawula inkampani kakhulu ngelungelo lokwenza imali eninzi kwabanye abantu…
Njengoko izixhobo ezixhaswe yi-USB zixhaphake ngakumbi, ndacinga ngento efana ne-5V. Kungcono nokuba kuninzi i-5V USB C kumazibuko kunye namazibuko e-AC amaninzi. Ukusuka apho, ungasebenzisa i-5V yezixhobo zamandla aphantsi kunye ne-USB C yezixhobo zamandla aphezulu. Icala elisezantsi kukuba amazibuko e-USB C kufuneka aphathe amandla ombane kwizibuko ngalinye ngelixa i-USB A 5v inguloliwe we-5v nje.
Ubuncinci, ndiqinisekile ukuba ndiza kugqiba ukwakha iofisi ene-5V ye-USB esebenza ngamandla. Ndingenza kwakhona i-12V, njengoko iiprojekthi zam zombane ezifuna ngaphezulu kwe-5V phantse zihlala zifuna i-12V. (Kwakhona, ndiqinisekile ukuba yonke i-router yam isebenzisa i-12V, kwaye kuya kuba kuhle ukuba neendawo zokuphuma ezilula kwisixhobo ngasinye endaweni yesiguquli sodonga!)
Uxolo ukukuxelela ukuba i-5V (okanye i-12V) ayilunganga kunikezelo lwamandla: imitha nje okanye ezimbini zentambo yokutsala enelahleko ye-10% okanye ngaphezulu ayinakusetyenziswa. Iimoto zisokola nge-12v ngalo lonke ixesha, kodwa kuba zincinci ziyakwazi ukuyiphatha, kodwa iilori kunye nezikhitshane ezinkulu zisebenzisa i-24v, ke ewe, i-48v yeyona xabiso lilungileyo: iseyinqanaba loluhlu olukhuselekileyo logama nje ungayikhothi. . amandla ombane asemgangathweni, izixhobo ezaneleyo kunye nokukwazi ukuthutha ubude obuthile ngaphandle kwelahleko eninzi.
Ilahleko yokuguqulwa kwamandla ibaluleke ngaphezu kokulahleka kwentambo. Ngokomzekelo, kwimeko yeli nqaku, sicinga ukuba ukuguqulwa kwe-DC-to-DC nganye yi-90% esebenzayo, siphela silahlekelwa yi-27% yamandla esiwafumana kwishaja ye-5V ye-USB. Ukuba umguquleli ubi kakhulu, ngo-85%, ngoko ilahleko iya kufikelela kwi-39%. Izilawuli zokutshaja kunye nabaguquli ekusebenzeni bafikelela kwi-80% yokusebenza kakuhle, ngoko ke ayiqhelekanga ukuphulukana nesiqingatha samandla ngenxa yolawulo lombane. Ukuba imfuno yenkqubo iphantsi, ilahleko yezixhobo ezingasebenziyo inokusebenzisa phantse onke amandla.
Ngaphandle kokuba usebenzisa iintambo ezishinyeneyo, ilahleko yentambo inokuba phezulu kakhulu kwi-5V, kwaye uya kuchitha ngaphezulu kwezo ntambo kunokuba ubuya kwenza uguqulo olusebenzayo lwe-24V.
Ukuba uneshumi elinesibini le-5W lezibuko le-USB, udinga umbane we-120W. Ukuba unikezelo lwamandla lunomthwalo osisigxina wesiseko se-10W, "ukusebenza kakuhle" kumthwalo ochaziweyo kuya kuba ngama-92%, kodwa xa umyinge wokusetyenziswa kwe-port ye-USB malunga ne-5%, ukusebenza kakuhle kwenkqubo yokwenyani malunga ne-60%. .
Nantoni na engaphantsi kobuncinane obupheleleyo obuyi-36V akufunekanga isetyenziswe kumgama omde. Ngokukodwa hayi i-5v. Iiadaptha zamandla zitshiphu kakhulu, ubhedu luyabiza kwaye lunzima. Iibhetri nazo ziyabiza kwaye ukuphulukana nombane kuyingxaki.
Ngokwam, andizukwenza naluphi na uhlobo lwe-LVDC microgrid kwaphela (ndandidla ngokudlala ngayo kwaye ndiyithiyile kakhulu ndenza ividiyo epheleleyo ngayo).
Ndihlala ndithi beka ibhetri kwindawo yomthwalo kwaye usebenzise intambo yokwandisa ukuba ufuna amandla. Imeko eyahlukileyo yi-PoE, esimahla simahla kwi-Ethernet kwaye unokuyifuna ngezinye iinjongo.
I-USB-C yazo zonke iiprojekthi zakho, inikwe amandla ziibhetri zangaphandle kunye neeadaptha zodonga njengoko kufuneka. Qaphela ukuba iimodyuli ze-USB-PD zokubangela zikhona, ungafumana 9, 15 okanye 20 ukuba uyathanda (i-12V iphelelwe lixesha kwaye mhlawumbi ayiyi kusebenza ngeeadaptha ezintsha ze-IIRC)
Ukuba ufuna ukusebenzisa amandla elanga, i-12V ilungele ukubaleka encinci ukuya kuthi ga kwi-100W yeenyawo ezimbalwa, kwaye ixhaphake kakhulu kune-5V kunye ne-48V njl njl, yiya kuyo. Okanye uthenge nje i-LifePO4 ijenereyitha yelanga, ziyamangalisa.
Wonke umntu onqwenela ukuzenzela usoloko efuna ukwenza into ngebhasi ye-DC, kodwa loo nto idla ngokuba yinto embi kuba izixhobo zabathengi azenzelwanga kwaye uphulukana nombono “wemisebenzi nje” yentsumpa ye-USB ephela yonke indawo. Indawo. Ziintambo ezinkulu kunye neqela leeqhagamshelo ezingekho mgangathweni ezingahambelaniyo nehlabathi liphela kwaye ziyingxaki kwinkqubo yakho ye-DIY.
Olona phumezo lungcono endilubonileyo lumgangatho we-ARES werediyo ye-ham, kodwa nalapho... ilungile kuphela imitsi emifutshane.
Ngamandla e-5V eofisini, ndisebenzisa nje i-outlet yodonga kunye ne-transformer eyakhelwe-ngaphakathi kunye ne-USB port.
Kuba 12V kuba imizila kunye nezinye izinto ukucima, Bendiya nje ukuthenga enkulu 12V 5A isiguquli kunye 2.1mm Y-intambo (qiniseka ukuba ufumana ezindilisekileyo) okanye ulinde de imodyuli yokuqalisa iyafumaneka PPS for 12V, thatha 12V. I-USB esuka kwizixhobo ezitsha - izibuko C.
Okanye ngcono noko, khupha amandla angengawo awe-USB nanini na kunokwenzeka. Ukuchitha kancinci kuphuculo lokufumana zonke ii-USB-PDs kuya kuyisombulula yonke ingxaki xa ufuna umzila omtsha okanye nayiphi na i-router ephezulu enokuthi inikwe amandla e-USB.
Ukuba bendifuna nyani i-12V yokuphuma, bendiya kuqwalasela ukubeka i-Mean Well enentambo yesiguquli kwibhokisi yenkonzo esecaleni kwendawo yokuphuma endaweni yokusebenzisa i-12V. Akukho nqaku elinye lokusilela, ukulahleka kwamandla kwintambo engqingqwa okanye encinci, ukulungiswa okulula nokucacileyo.
I-120V DC ilungile ukunika amandla uninzi lwemithombo “ye-AC”, kodwa ngowona mda usezantsi wento abonwabe ngayo. Bakhetha i-160VDC okanye ngaphezulu.
Hayi, kumava am banqumle malunga ne-65Vdc, kodwa kuya kufuneka uphinde ujonge ngaphantsi kwe-130Vdc, khange ndilinganise, kodwa ndithatha i-100-0% yehla ukusuka kwi-130-65Vdc.
Ukucinga okungaqhelekanga. Ndicinga ukuba i-input circuit iphatha i-fixed current. Oku kuthetha ukuba xa i-voltage ifikelela kwi-130V ukuya kwi-65V, ukulinganiswa kuyancitshiswa ukuya kwi-50%, kwaye ngaphantsi kwe-65V, enye enye isiphaluka sokuthintela umbane ibangelwa.
Izitishi ezininzi zinebhetri enika amandla i-relays yokhuseleko kwaye ivumela ii-breakers zesekethe ukuba zisebenze (zivule kwaye zihlawule) xa kwenzeka umbane. Umbane oqhelekileyo yi-115 VDC. Isebenzisa i-100% kwibhetri kwaye ine-AC-> DC ishaja ukuqinisekisa ukuba ibhetri isoloko ihlawulwe ngokupheleleyo, ngoko akukho solar kule meko.
Ngokwencwadi kaMotzenbocker ethi "Ukubuyisela Amandla" https://yugeshima.com/diygrid/ 120vdc kuphela
Ingxaki yokuhanjiswa kwamandla e-DC yasombululwa ngoncedo lwe-802.3af (aka PoE) - Amandla phezu kwe-Ethernet. Akukho mfuneko yokusebenzisa inxalenye ye-Ethernet ye-equation. I-adapters ezihlala kuyo yonke indawo, ukuhanjiswa kwamandla okukhuselekileyo kunye nezixhobo ezibalaseleyo zokunika ingxelo / zokulawula. Ayibizi nakancinci – ungafumana i-100Mbps ye-48-port yenqanaba leziko ledatha yehabhu ngexabiso eliphantsi njenge-£30.
Ihotele iMarcel eseNew Haven inamagumbi ali-164, onke aqhutywa ngamandla elanga kunye neengcingo zeDC. Nantsi isishwankathelo esihle: https://www.youtube.com/watch?v=J4aTcU6Fzoc.
Bendiza kuyikhankanya, basebenzisa i-POE. Ilahleko ebangelwa kukusebenza kufuneka ibe ngaphantsi kwelahleko xa utshintshela kwi-DC ukuya kwi-AC nokubuyela kwi-DC. Kwakhona kukunika uhlalutyo olwakhelwe ngaphakathi malunga nento oyisebenzisayo.
Ngamanye amaxesha ndiye ndilibale ukuba ndihlala ngaphandle kweintanethi. Ndine-48VDC ukuya kwi-220VAC inverter kwi-setup yam ekhupha malunga ne-5kW ngokuqhubekayo, nangona ingazange ilayishwe kakhulu. Ipompo yamanzi engama-220 volt, ifriji, ifriji, izixhobo zombane, izixhobo, ukukhanya, konke oku kusemgangathweni kwimigxobhozo. Ndine-12V kunye ne-24V DC eyahlukileyo kunye/okanye ezinye iintlobo zoseto lwamandla. Qhuba ishishini lentsimbi kwiziko elinye kwaye umpompe amanzi okusela ihashe elikhulu. Iibhetri zisuka kwinkqubo enkulu ye-UPS endiyifumanayo xa nditshintsha iibhetri kwishedyuli. Yenza uvavanyo lwe-voltage kwiibhetri, khetha ezona zibalaseleyo, emva koko ufake i-heater yokumelana, uphinde ubeke iliso kwi-voltage, khetha ezona zibalaseleyo kwakhona kwaye uzithenge.
Ewe, uninzi lwezixhobo ezinokufakwa kwe-AC "kwindawo yonke" zinokusebenza ngamandla eDC. Phindaphinda-phinda amandla ombane we-AC nge-1.4 ukufumana amandla ombane e-DC alinganayo. Nangona kunjalo, i-fuses yabo yangaphakathi ayilinganiswanga yi-DC. Zitshintshe nge fuse yeDC okanye usebenzise ifuse yangaphandle. Musa ukutshisa indlu!
> "Oku kuthetha ukuba umbane ophezulu wesiphaluka umalunga ne-0.80 V. Kwimeko yomlilo (ngethemba lokuba awusoze), oku akuyi kuba yingozi enkulu kwi-fire brigade."
Umgangatho we-ELV uqwalasela i-120 VDC "ekhuselekile" ngaphandle kwe-ripple, kodwa i-EU General Safety Standard iyayikhawulela kwi-75 VDC, ngelixa i-Low Voltage Directive isebenza kuyo nayiphi na i-voltage kwi-75-1000 VDC. Usengawaphula umthetho kwaye ufuna imvume yokufaka inkqubo enjalo, kodwa kunzima ukufumana impendulo ecacileyo okanye nawaphi na amaxwebhu ento kanye onokuyenza njengomakhi wedwa ngaphandle koqeqesho olukhethekileyo.
