1. Yintoni umbane wangaphandle kwaye yintoni umahluko phakathi kwayo kunye nebhanki yamandla?
Amandla angaphandle, eneneni abizwa ngamandla angaphandle ahambayo, alingana nesikhululo sokutshaja esiphathwayo.Olona phawu luphambili luqwalaselo lweentlobo ngeentlobo zamazibuko emveliso:
I-USB, i-TypeC, inokuhlawula izixhobo eziqhelekileyo zedijithali.
Ujongano lokutshaja imoto, inokutshaja ibhetri yemoto, okanye amanye amandla esixhobo sebhodi.
Inkxaso ye-220V imveliso ye-AC, elingana nokusetyenziswa kwamandla amakhulu ekhaya.
Yintoni umahluko phakathi kwayo kunye nebhanki yamandla?
1. Amandla emveliso
Okwangoku, ibhanki yokutshaja ifowuni ephathwayo kwimarike, amandla emveliso phantse 22.5W.Ibhanki yamandla yelaptop, i-45-50W.
Amandla ombane angaphandle aqala kwi-200W, ezininzi iimpawu zingaphezulu kwe-500W, kwaye ubuninzi bunokuba ngaphezu kwe-2000W.
Amandla aphezulu athetha ukuba ungasebenzisa izixhobo zombane eziphezulu.
2. Umthamo
Phambi kokuba ndithelekise umthamo, kufuneka ndikuxelele malunga neeyunithi.
Iyunithi yebhanki yamandla yi-mAh (mah), ebizwa ngokuba yi-mah ngokufutshane.
Iyunithi yonikezelo lwamandla lwangaphandle yiWh (watt-yure).
Kutheni kukho umahluko?
1. Ngenxa yokuba i-voltage ye-output yebhanki yokutshaja incinci, i-voltage ephumayo yebhanki yokutshaja ifowuni yeselula i-3.6V, efana ne-voltage yokusebenza yefowuni ephathekayo.
Kwakhona ngenxa yengxaki yombane, ukuba ufuna ukusebenzisa ibhanki yamandla ukuhlawula i-laptop yakho (i-voltage esebenzayo 19V), kufuneka uthenge i-laptop ekhethekileyo.
2 Wh, le yunithi, eneneni ibhekisa kusetyenziso lwamandla okanye umthamo, onokuthi awuzange uwubone.Kodwa makhe ndithethe oku, kwaye uya kufumana ingqiqo yayo:
1000Wh = 1kWh = 1 KWH.
Ifomula yokuguqulwa kwezi yunithi zimbini: W (umsebenzi, iyunithi Wh) = U (i-voltage, iyunithi V) * Q (intlawulo, iyunithi Ah)
Ngoko ke, ibhanki ye-20000mAh yokutshaja ifowuni yeselula, umthamo wayo ngu-3.6V * 20Ah = 72Wh.
Umthamo wombane jikelele wangaphandle ubuncinci ubuyi-300Wh.Nantso isithuba umthamo.
Umzekelo: (kungakhathaliseki ilahleko)
Umbane osebenzayo webhetri yeselula ngu-3.6V, umrhumo ngu-4000mAh, ngoko amandla ebhetri yeselula = 3.6V * 4Ah = 14.4Wh.
Ukuba i-20000mAh yokutshaja ibhanki, ukuhlawula le fowuni yeselula, inokuhlawula i-72 / 14.4 ≈ ngamaxesha angama-5.
Unikezelo lwamandla lwangaphandle lwe-300Wh lunokuhlawuliswa 300/14.4 ≈ amaxesha angama-20.
2. Yintoni enokwenziwa umbane wangaphandle?
Xa ufuna umbane ngaphandle, izixhobo zombane zangaphandle zinokukunceda.Umzekelo,
1. Misa indawo yokuthengisela yangaphandle kwaye unikeze amandla kwiibhalbhu zokukhanya.
I-2, inkampu yangaphandle kunye nokuhamba ngokuziqhuba, kukho iindawo ezininzi zokusebenzisa umbane, ufuna ukudinga umbane, amandla angaphandle angenza.
Sebenzisa iprojektha
Fudumeza amanzi ashushu kwaye upheke nge-rice cooker
Kwiindawo apho amadangatye avulekileyo anokungavunyelwa, umthombo wamandla wangaphandle uya kukuvumela ukuba usebenzise isitovu sakho serayisi ngokukhuselekileyo.
Ukutshaja isixhobo sedijithali (i-UAV, ifowuni ephathwayo, ikhompyuter)
Sebenzisa ifriji yemoto
I-3, ukuba i-RV, ixesha elide ngaphandle, amandla angaphandle anokuba yinto efunekayo.
I-4, i-ofisi yeselula, xa kungekho ndawo yokuhlawula, unokuqinisekisa ukuba ikhomputha okanye ifowuni yeselula, ukukhathazeka okuhlukeneyo malunga nengxaki yombane ixesha elide, ubomi bebhetri bunamandla kakhulu kunebhanki yamandla.
I-5, kubahlobo bokuloba intsimi, umbane wangaphandle unokuhlawulisa ukukhanya kokuloba endle, okanye ngokuthe ngqo njengesibane sokuloba esinokusetyenziswa.
6. Kubahlobo abafotayo, umbane wangaphandle ungowona mboniso usebenzayo:
Endaweni yokuba uphathe iibhetri ezininzi, ukunika amandla izibane zekhamera.
Okanye njengezibane ze-LED, gcwalisa ukusetyenziswa kokukhanya.
I-7, ukusebenza kwangaphandle, kwizixhobo eziphezulu zamandla, amandla angaphandle nawo ayimfuneko.
8. Ugcino olungxamisekileyo.
Akunyanzelekanga ukuba ube ngaphandle ukuze usebenzise amandla angaphandle.Xa kukho ukusilela kombane ekhaya, umbane wangaphandle ungasetyenziswa njengesibane esingxamisekileyo.
Ngokomzekelo, iintlekele zendalo ezahlukeneyo zalo nyaka, ukuphuma kwamandla okuhlala akufiki ixesha elide, ukubaluleka kokunikezelwa kwamandla angaphandle kubonakala.Amanzi ashushu, ukutshaja iiselfowuni, njl.
3, khetha unikezelo lwamandla lwangaphandle, yintoni imfuneko yokunikela ingqalelo?(Amanqaku aphambili)
1. Yintoni ukusetyenziswa kwamanzi?
Zonke izixhobo zombane, kukho ukusetyenziswa kwamandla.Ukuba amandla ebhetri akakho kuyo, awukwazi ukuyithwala.
2. Umahluko phakathi kwe-mAh kunye ne-Wh.
Nangona igutyungelwe kancinci apha ngasentla, le yeyona ngongoma ilahlekisayo, ke mandiyicacise.
Ngelizwi: awukwazi ukuxelela ukuba yintoni umthamo wangempela xa ujonga nje i-mAh, kuba amandla ombane ahluke.
mAh (milliampere) yiyunithi yombane emele isixa sentlawulo Q enokuthi ibanjwe okanye iyikhulule ibhetri.
Okuqhelekileyo kukuba: sithetha malunga nomthamo webhetri yeselula okanye ibhanki yamandla, zingaphi ii-milliamps.
I-Wh iyunithi yokusetyenziswa kwamandla, emele umsebenzi onokwenziwa yibhetri.
I-Wh ibizwa ngokuba yi-watt-yure, kunye ne-1 kilowatt iyure (kWh) = 1 kilowatt yeyure yombane.
Ukuguqulwa phakathi kweWh kunye ne-mAh: Wh * 1000/ amandla ombane = mAh.
Ngoko uninzi lwangaphandle lwamandla oshishino uphawu lwe-mAh, luguqulwa ngumbane wefowuni yeselula 3.6V, bonisa umthamo omkhulu.
Umzekelo, i-600Wh inokuguqulwa ibe yi-600 * 1000/3.6 = 166666mAh.
Ukushwankathela kancinci:
I-1, amandla amancinci angaphandle angaphandle (300W ngezantsi), ngakumbi ukubona i-mAh, kuba ukunyamekela ngakumbi kukuba: zingaphi izihlandlo izixhobo zombane ezinokuhlawuliswa.
I-2, amandla amakhulu ombane angaphandle (ngaphezu kwe-500W), ngakumbi ukubona i-Wh, kuba unokubala ngcono ixesha lonikezelo lwamandla ezixhobo zombane eziphezulu.
Ngokomzekelo, i-500W i-rice cooker + 600Wh umthamo wamandla ombane wangaphandle, unokubala ngokuthe ngqo ixesha elisebenzisekayo: 600/500 = 1.2 iiyure.Ukuba ikwi-mAh, kunzima ukuyifumanisa.
Ukuba awuqinisekanga, swayipha ukuya esiphelweni senqaku, apho ndiye ndashwankathela ezinye izixhobo zombane, kwaye zingaphi izihlandlo ezihlawuliswe ngazo okanye zinikwe amandla ixesha elingakanani.
3. Imo yokutshaja
Iimayini (zitshaja ekhaya)
Intlawulo yokuqhuba
Ukutshaja ipaneli yelanga (Ngaphandle)
Ukuba uchitha ixesha elininzi ngaphandle, okanye kwi-RV, iipaneli zelanga ziyimfuneko.
Xa uthengela umbane wangaphandle, iimpawu ezahlukeneyo zine-combo: amandla angaphandle kunye neepaneli zelanga (amaxabiso aya kwanda).
4. Ukubaleka
Izixhobo ezi-2 zangaphandle zamandla ngokunxuseneyo, zonyusa amandla obungakanani.
Umbane omnye wangaphandle +1~2 iipakethi zokutshaja.
Ipakethi yamandla inokusetyenziswa kuphela njengebhetri, ngokubambisana nokunikezelwa kwamandla ngaphandle, onomsebenzi omncinci kakhulu.
5. Imveliso yamaza
Kuphela i-sine wave ecocekileyo, ayiyi konakalisa izixhobo zombane, ngakumbi izixhobo zedijithali, ngoko kufuneka ubeke ingqalelo ekuthengeni.
Ezi ndizidwelise ngezantsi ngamaza e-sine acocekileyo, ngaphandle kwe-Habilis.
5. Iingcebiso zomzekelo
Ngaphantsi kwe-1,300 W
2,600 W
3,1000 W ukuya kwi-1400W
4,1500 W-2000W (iza kuqhubeka)
Nazi izinto ezimbalwa ekufuneka uziqaphele:
Amandla ombane angaphandle angaphantsi kwe-1,300 W aneemeko ezilinganiselweyo zesicelo ngenxa yamandla aphantsi
Ukukhanya okungxamisekileyo
Indawo yokutyela yangaphandle
Ukutshaja isixhobo seDijithali
Ngenxa yokuba ukhathalelo olungakumbi malunga nomthamo, ngoko lo mfanekiso ulandelayo wokuthelekisa, umthamo awukho Wh, kwaye usebenzise i-mAh ukubonisa ngokucacileyo ngakumbi.
Kunikezelo lwamandla lwangaphandle ngaphezulu kwe-2,600 W, indlela yenqanaba endiyicebisayo ngolu hlobo lulandelayo:
Kwindlela yokunyuka kwamandla aphezulu kunye nomthamo webhetri
Kwaye ngoko kunyuka komyalelo wexabiso.
Kutheni ungacingi ngexabiso kuqala?
Isizathu silula.Kufuneka uqinisekise ukuba unamandla amakhulu kunye nomthamo ngaphambi kokuba uqwalasele ixabiso.
Kwaye uyilo lonikezelo lwamandla lwangaphandle ngokubanzi, umthamo nawo unyuswe ngamandla.
3. Ezinye iiparamitha:
Amandla aphezulu.Ezinye izixhobo zombane, njengeempompo zomoya okanye izibane ezidanyazayo, zinamandla angoko nangoko, nto leyo ethetha amandla amaninzi okomzuzwana.
