I-inverter enkulu kangakanani edingwa ngempela yilebhu yamakhompyutha yesikole enamakhompyutha angu-30?
Ukuze amadeskithophu esikole ajwayelekile angu-30 kanye nemishini yenethiwekhi kuqhubeke kusebenza isikhathi sokucishwa kukagesi esingamahora amabili, udinga i-inverter engu-8kW kanye nokungenani u-10kWh wesitoreji sebhethri le-lithium. Ukuzama ukusekela amaphrinta e-3D kuzophindaphinda kabili izindleko zakho—nakhu ukuthi ungahlela kanjani kunalokho isistimu yokusekela eyakhiwa ngezigaba, ehambisana ne-SGB.
Ukuze ilebhu yamakhompyutha yesikole yaseNingizimu Afrika ejwayelekile enamadeskithophu angu-30, isiteshi sothisha kanye nenethiwekhi yasendaweni kuqhubeke kusebenza kuwo wonke amahora amabili ajwayelekile okucishwa kukagesi, udinga i-inverter engu-8kW kanye nokungenani okungu-10.24kWh kwesitoreji sebhethri le-lithium iron phosphate (LiFePO4).
Uma uzama ukwengeza ngisho amaphrinta e-3D amabili noma amathathu kule sistimu yokusekela, isabelomali sakho sizowa. Izingxenye ezishisayo zamaphrinta e-3D zidonsa umthwalo omkhulu we-resistive odinga i-inverter enkulu kakhulu futhi ziqeda ngokushesha amandla ebhethri abizayo.
Ngaphambi kokuba iSigungu Esilawulayo Sesikole (i-SGB) sivume isilinganiso sentengo esibizayo, esikhulu ngokweqile se-solar noma sokusekela, kudingeka uqonde ukudonswa kukagesi kwangempela kwelebhu yakho nokuthi kungani indlela eyakhiwa ngezigaba, ebheka izinto ezenzekayo, cishe ihlala iyisinqumo sezimali esingcono kunazo zonke.
Izibalo zangempela zelebhu enamakhompyutha angu-30
Abafaki abaningi be-solar basebenzisa amafomula ajwayelekile ayeqisa izidingo zikagesi zesikole, okuholela ezilinganisweni zentengo ezikhukhumele. Abanye behlisa umthwalo, okuholela ezisistimu eziphuma emsebenzini ngesikhathi nje ikilasi lihlala phansi. Ukuze sithole ibhalansi elifanele, kumele sibale umthwalo wangempela oqhubekayo wemishini yakho.
- Amadeskithophu ajwayelekile: Ideskithophu yesikole ejwayelekile (umbhoshongo waphakathi nendawo kanye nesikrini se-LCD samayintshi angu-19) idonsa phakathi kuka-80W no-120W ngokusetshenziswa okujwayelekile ekilasini (ukubhala ikhodi, ukuphequlula i-inthanethi, noma izinhlelo zokusebenza zehhovisi). Sizosebenzisa isilinganiso sika-100W kusiteshi ngasinye. Kubafundi abangu-30, lokho kungu-3,000W (3kW).
- Isiteshi sothisha kanye ne-projector: Ikhompyutha kathisha idonsa u-100W, kanti i-projector ejwayelekile yekilasi idonsa cishe u-250W kuya ku-300W. Ndawonye lokhu kwengeza u-400W.
- Imishini yenethiwekhi: I-switch yenethiwekhi yelebhu, indawo yokungena ye-Wi-Fi kanye ne-router ye-fibre kudonsa u-50W kuya ku-100W ngokungaphezi.
Ngaphandle kwamaphrinta e-3D, umthwalo wakho oyisisekelo oqhubekayo ucishe ube 3.5kW.
Ukusebenzisa umthwalo ongu-3.5kW isikhathi esijwayelekile samahora ama-2 okucishwa kukagesi, udinga amandla angu-7kWh angasetshenziswa. Nokho, ama-inverter awasebenzi ngokugcwele nga-100% (amaningi asebenza cishe ngo-90%), futhi amabhethri e-lithium akufanele ehliswe njalo aze afike ku-zero ngokuphelele. Ukuqinisekisa ukuthi isistimu iphila isikhathi esigcwele samahora ama-2 ingacimi, udinga okungenani u-10.24kWh wamandla ebhethri (ngokuvamile ohlelwe njengamabhethri amabili angu-5.12kWh afakwe erakini).
Kungani amaphrinta e-3D ebulala isabelomali kuzisistimu zokusekela
Iphrinta ye-3D empeleni iyisibhamu seglue esilawulwa kakhulu, esinembayo. Ukuze incibilikise i-filament yepulasitiki, kumele ishisise umlomo wethusi ufike cishe ku-200°C nombhede wokuphrinta ufike ku-60°C. Le nqubo yokushisisa incike ezingxenyeni ezishisayo ze-resistive.
Nakuba iphrinta ye-3D ingase idonse u-50W kuphela lapho ingasebenzi noma igcina izinga lokushisa, idonsa phakathi kuka-250W no-350W esigabeni sokuqala sokushisisa. Uma uthisha eqala isifundo bese abafundi abahlanu beshisisa amaphrinta e-3D amahlanu ngasikhathi sinye, lokho kumele ukwenyuka okusheshayo kwesidingo okungu-1.5kW.
"Ukusekela izingxenye ezishisayo ezifana namaphrinta e-3D, ama-laminator noma ama-laser cutter kusistimu yebhethri yesikole kuyiphutha elibiza ngokwedlulele. Ukhokha amanani abhethri aphezulu ukuze ukhiqize ukushisa okuyisisekelo."
Ukwengeza amaphrinta e-3D kusistimu yakho esebenzayo yokusekela kukuphoqa ukuthi uthenge i-inverter enkulu (okungenani engu-12kW) ukuze imelane nokwenyuka kwamandla ekuqaleni, futhi uphindaphinde kabili amandla ebhethri lakho ukuvimbela amaphrinta ekuqedeni amandla esistimu ngaphambi kokuphela kwesifundo. Lokhu kungangeza kalula u-R40,000 kuya ku-R60,000 ezindlekweni zakho zokufakwa.
Isixazululo esisebenzayo: Gcina amaphrinta akho e-3D kulayini oyinhloko kagesi kamasipala, weqe i-inverter ngokuphelele, bese uhlela imisebenzi yakho yokuphrinta nge-3D ngaphandle kwamahora okucishwa kukagesi. Uma umsebenzi wokuphrinta ubalulekile, amaphrinta amaningi e-3D anamuhla anomsebenzi wokuthi "qhubeka nokuphrinta ngemva kokuphela kukagesi" ovumela ukuthi ukuphrinta kume ngokuphepha bese kuqhubeka lapho ugesi ubuya.
Isu lokusekela elakhiwa ngezigaba, elihambisana ne-SGB
Iningi lezikole alikwazi ukukhipha u-R120,000 wemali yokutshala kusistimu egcwele yokusekela yelebhu ngonyaka owodwa wesabelomali. Indlela eyakhiwa ngezigaba ikuvumela ukuthi uqale uvikele imisebenzi ebaluleke kakhulu, bese wandisa isistimu njengoba imali ivuma.
| Isigaba | Okunikwa amandla | Umthwalo oqhubekayo | Usayizi we-inverter | Amandla ebhethri | Izindleko ezilinganiselwe (kufaka ukufakwa) |
|---|---|---|---|---|---|
| Isigaba 1: Okuyinhloko kuphela | Inethiwekhi, i-router, ikhompyutha kathisha, i-projector | ~450W | 3kW (i-phase eyodwa) | 2.56kWh | R25,000 – R35,000 |
| Isigaba 2: Ilebhu exubile | Inethiwekhi, ikhompyutha kathisha, i-projector, amakhompyutha abafundi angu-10 | ~1.45kW | 5kW (i-phase eyodwa) | 5.12kWh | R50,000 – R65,000 |
| Isigaba 3: Ilebhu egcwele | Inethiwekhi, ikhompyutha kathisha, i-projector, amakhompyutha abafundi angu-30 | ~3.45kW | 8kW (i-phase eyodwa) | 10.24kWh | R95,000 – R120,000 |
Ngokuqala nge-Sigaba 2, ngokwesibonelo, isikole singaqinisekisa ukuthi okungenani ingxenye eyodwa kwezintathu yekilasi iyakwazi ukuqhubeka isebenza ngesikhathi kunqamuka ugesi, noma ukuthi imisebenzi yokuhlola (njengezivivinyo ezingokoqobo) iqhubeke ingaphazanyiswa. Uma isikole sakho sihlela ukuvuselela ilebhu njengamanje, ukukhetha amadivayisi asebenzisa amandla kancane afana nama-mini-PC noma amalabhithophu esikhundleni sembhoshongo yamadeskithophu ajwayelekile kuyiyona ndlela engcono kunazo zonke yokwehlisa izindleko zakho zokusekela ekugcineni; ithimba lethu lingasiza ngalolu hlelo ngezinsizakalo zethu zokuthola nokufaka imishini yelebhu.
Izinto ezibalulekile ngengqalasizinda okumele izikole zizicabangele
Ngaphambi kokuba wamukele isilinganiso sentengo somfaki, qinisekisa ukuthi isikole sakho sesibhekene nalezi zindawo ezintathu ezivamile zokwehluleka:
- Ukunqamuka kwe-Wi-Fi ye-WPA2-Enterprise: Amanethiwekhi e-Wi-Fi ezikole asebenzisa ukuqinisekiswa kwe-enterprise ngokuvamile athatha imizuzu emi-5 kuya kweyi-10 ukuqalisa kabusha nokuqinisekisa kabusha amadivayisi ngemva kokwehla kukagesi. I-inverter yakho kumele ibe nesikhathi sokudlulisa amandla esingabonakali (ngaphansi kwama-millisecond ayi-10) ukuze i-switch yenethiwekhi ne-router zingalokothi zikubone ukunqamuka kukagesi, kugcinwe abafundi bexhumekile ngaphandle kokuphazamiseka.
- Ukuphepha kwendawo nokungena komoya: Ama-inverter namabhethri e-lithium kumele agcinwe ekamelweni elivikelekile, elikhiyiwe ukuvimbela ubusela nokucekelwa phansi. Nokho, akhipha ukushisa okukhulu lapho esebenza. Ukuwabeka ekhabetheni elincane leseva elingangeni moya kuzoholela ekwehlisweni kwamandla ngenxa yokushisa nasekonakaleni kwebhethri ngaphambi kwesikhathi. Qinisekisa ukuthi indawo yokufakwa ingena umoya kahle futhi ayinathuli.
- Ukuhambisana nemithetho ye-SGB kanye ne-CoC: Noma yikuphi ukufakwa kwe-solar noma kwesistimu yokusekela esikoleni saseNingizimu Afrika kumele kuhambisane nesitifiketi esisemthethweni sokuhambisana nemithetho (i-CoC) esikhishwe ngukhontileka kagesi obhalisiwe. Ngaphandle kwalokhu, umshwalense wesakhiwo sesikole sakho uzoba yize uma kwenzeka umlilo kagesi.
Uma udinga usizo lokuhlola ingqalasizinda yesikole sakho yamanje, ukuklama isabelomali sikagesi esifanele, noma ukuthola imishini eqinile ehambisana nesabelomali sakho se-SGB, hlola izinsizakalo zethu zokusekela izikole ubone ukuthi sizisiza kanjani izikole zaseNingizimu Afrika ukudlula kulezi zinguquko zobuchwepheshe ngokuphepha.
