Uma sikhuluma ngamandla elanga noma omoya, namaphrojekthi asebenzisa lolu hlobo lwamandla avuselelekayo, sihlala sibhekisela ezilinganisweni zamandla ezivamile ensimini: amahora angama-kilowatt noma ama-megawatts amandla. Abantu abaningi bayakungabaza mangaki ama-kilowatts i-megawatt.
Ngenxa yalesi sizathu, sizonikezela lesi sihloko ukuze sikutshele ukuthi mangaki ama-kilowatts ayi-megawatt, yiziphi izici ezinazo futhi uma lokhu kuthonya isikweletu sikagesi.
Iyini i-kilowatt-hora noma i-megawatt yamandla?
Izikhathi eziningi sibuzwa ukuthi singakala kanjani ukuthi kudla malini ikhaya, indlela yokukala amandla esitshalo selanga noma ipulazi lomoya, Yingakho sizokwenza isifundo ukuxazulula lokhu kungabaza.
Ngaphambi kokuqonda noma ukuchaza kabanzi ukuthi iyini i-kilowatt-hora noma i-megawatt yamandla, kufanele siqale sichaze ukuthi leyunithi yamandla noma amandla iqukethe ini.
I-Watt (W) iyunithi yamandla, okuyimvamisa lapho amandla akhiqizwa noma asetshenziswa khona. Ama-Watts angacatshangwa njengeyunithi yokulinganisa kwamandla kagesi. Ingabe okokusebenza kukagesi kudinga ukugeleza okuphezulu noma okuphansi ukuze kusebenze? Isibonelo, isibani esingu-100 W sisebenzisa amandla amaningi kunesibani esingu-60 W; lokhu kusho ukuthi isibani esingu-100W sidinga "ukuguquguquka" okwengeziwe ukuze sisebenze. Ngokufanayo, imvamisa lapho amandla avela kusistimu sonozungezilanga "egeleza" eya ekhaya lakho akalwa ngama-watts.
Ngale ndlela, ama-watts noma ama-watts angasetshenziswa ukukala kokubili amandla omshini othile kagesi kanye amandla ewasebenzisayo noma ewathuthukisayo esimweni semithombo yamandla avuselelekayo. Uma udla kakhulu, iyunithi yokulinganisa yi-kilowatt, elingana ne-kilowatt eyodwa. Uma inkulu, izoba ngama-megawatts, okungukuthi, ama-watts ayisigidi noma ama-kilowatts ayinkulungwane.
Amahora we-Kilowatt nokubaluleka kwawo
Kulokhu kufanele futhi kwengezwe umqondo wama-kilowatt-amahora, okuthi, esimweni sokulinganisa amandla, isilinganiso senani lomsebenzi owenziwe noma owenziwe ngehora elilodwa. Noma yiziphi izinto zikagesi nezinye izinto zikagesi ezindlini zethu zidinga ugesi ukuze usebenze.
Ngalesi sizathu, uma sizixhuma noma sizixhuma enkampanini noma enkampanini kagesi, izindleko abazenzayo zizoqala ukubalwa futhi sizobona izikweletu zifika ekupheleni kwenyanga, zikhokhiswa ngama-kilowatt-hour ( kWh), iyunithi yokulinganisa, njengoba sisho, ilingana namahora angu-1000 watt.
Futhi, ukwazi ukuthi i-kilowatt-hora iyini, singakwazi futhi ukuhlukanisa amandla ezinye izinto zasendlini. Isibonelo, i-microwave engu-1000-watt (1 kilowatt) izofudumeza ukudla ngokushesha kakhulu kune-microwave engu-600-watt. Ngenxa yalobu budlelwano phakathi kwamandla nesikhathi, Sisebenzisa amagama athi watt-hour (Wh) noma i-kilowatt-hour (kWh) ukuchaza ukusetshenziswa kwamandla.
Amahora we-Watt namahora e-kilowatt achaza inani lomsebenzi owenziwe noma amandla asetshenziswe ehoreni elilodwa. Isifaniso esilula siwukuthi isivinini isilinganiso esichaza ibanga elihanjiwe esikhathini esithile, kuyilapho amandla eyisilinganiso esichaza amandla asetshenziswa esikhathini esithile. Ukusebenzisa i-microwave efanayo engu-1000-watt (1 kW) ihora elilodwa kudla kufika ku-kilowatt-hora elingu-1 (kWh) lamandla.
kWh amamitha emakhaya
Kuzo zonke izakhiwo singathola amamitha wamandla (abuye abizwe ngamamitha kagesi) futhi kulawa mamitha kuhlale kukhona ukufundwa kwamandla ku-kWh.
Imitha ye-kilowatt-hour imitha kagesi ekala amandla kagesi asetshenziswa ekhaya ngamahora angama-kilowatt. Imitha yehora le-kilowatt inesibonisi esibala amayunithi wama-kilowatt-amahora (kWh). Ukusetshenziswa kwamandla kubalwa ngokubala umehluko ekufundweni kwamamitha esikhathini esibekiwe.
Izindleko zikagesi zibalwa ngokuphindaphinda izindleko ze-1 kWh ngenani le-kWh elisetshenzisiwe. Isibonelo, izindleko zikagesi zokusebenzisa u-900kWh ngenyanga ngamasenti angu-10 nge-1kWh ngayinye: 900kWh x 10 cents = 9000 cents = 90 euros. Ukusetshenziswa kwamandla endlini cishe ku-1.500 kWh ngenyanga noma 5 kWh ngosuku. Kuya ngesimo sezulu esithinta izidingo zokushisisa noma zokupholisa kanye nenani labantu abahlala ekhaya.
Mangaki ama-kilowatts i-megawatt?
Amahora we-Kilowatt abhekisela emananini ahlukene ento efanayo: amandla. Isinyathelo esilandelayo sokukhuphuka ukusuka ku-kilowatts ama-megawatts wamandla. 1 megawatt ilingana 1000 kilowatts noma 1 million watts, futhi ukuguqulwa okufanayo kusebenza kumahora we-megawatt nama-kilowatt-amahora. Ngakho uma i-oven microwave engu-1000-watt (1 kW) isebenza ngokuqhubekayo izinsuku ezingu-41,6, izosebenzisa ihora le-megawatt eli-1 lamandla (amawatts angu-1000/amahora angu-24 ngosuku = izinsuku ezingu-41,6).
Ukuze uqonde ngempela i-kWh ne-MWh, kubalulekile ukuqonda umongo lapho lawa mamethrikhi asetshenziswa khona. Isibonelo, noma yiliphi ikhaya elimaphakathi lisebenzisa cishe u-11,000 kWh wamandla ngonyaka, ngakho-ke sisebenzisa lolu lwazi singalinganisela ukusetshenziswa kwamandla okungaba ngu-915 kWh ngenyanga (noma ngaphezulu njengoba kushiwo ngenhla), futhi ukusetshenziswa kwamandla kwansuku zonke okungaba ngu-30 kWh kunoma iyiphi indlu yezwe yokuqala.
Uma ukhuluma ngokusetshenziswa kwamandla okuhlala, kuvame kakhulu ukusebenzisa amahora angama-kilowatt. Isikweletu sakho sanyanga zonke samandla sizobika ukusetshenziswa kwakho usebenzisa le methrikhi, futhi lapho uhlola ukuthuthukiswa kwamandla, njengokufakwa kwelanga, inkampani izoxoxa ngokuthi mangaki ama-kW uhlelo lwakho oludingayo ukuhlangabezana nezidingo zakho ze-kWh.
Ngokuphambene, I-MWh ivame ukusetshenziselwa ukubhekisela ekusetshenzisweni kukagesi ngezinga elikhulu.njengokwakhiwa kwesikhungo esisha sikagesi noma ukuqaliswa kokuthuthukiswa kwamandla edolobheni noma edolobheni. Kwesinye salezi zimo lapho kukhulunywa ngokusetshenziswa kwamandla amakhulu, isikhathi sokuzikhethela kuzoba yihora le-megawatt noma i-gigawatt-hour (GWh), kubhekiselwa kugigawathi eyodwa yamandla.
Njengoba ubona, lezi zinyathelo zamandla zibalulekile ekuhloleni ukusetshenziswa kwamandla ekukhiqizeni amandla avuselelekayo. Ngethemba ukuthi ngalolu lwazi ungakwazi ukwazi okwengeziwe ngokuthi mangaki ama-kilowatts ayi-megawatt.
