Iindaba - Ungakhetha njani imitha yombane?

Indlela yokukhetha imitha yombane ngoku?

Kukho amaxabiso amabini angoku kwiphaneli ye-smart meter, njengoko kubonisiwe kumfanekiso ongezantsi.ILinyangimithaamanqaku 5(60) A. 5A ngowona ukhoyo ngoku osisiseko kunye no-60A ngowona mlinganiselo uphezulu wangoku.Ukuba umsinga ungaphezulu kwe-60A, iya kulayishwa kakhulu kwaye imitha yokulinganisa iya kutsha iphele.Ngoko ke, xa ukhetha imitha ehlakaniphile, ngakwesinye icala, akufanele ibe ngaphantsi kwesiseko sangoku kwaye ngakolunye uhlangothi, akufanele ibe phezulu kunomlinganiselo ophezulu wangoku.

Masithi izixhobo zethu zasekhaya eziqhelekileyo: ikhompyuter ye-300W, i-TV ye-350W, i-air conditioner ye-1500W, i-400W yefriji, i-2000W yesifudumezi samanzi.Singabala ngolu hlobo lulandelayo: okwangoku = (300+350+1500+400+2000) W/220V≈20.6A.Siza kukwazi ukufaka i-5(60)A yeemitha ngenxa yokongezwa okunokwenzeka kwezixhobo kwixesha elizayo.

Zama ukukhetha uhlobo lwemitha ngokwendlela yangoku yemitha.Iimitha zombane zohlulwe ngokwemigangatho emithathu yombane kunye nenqanaba elinye lombane.Ngokuqhelekileyo, iimitha zombane ezithathu zisetyenziswa xa umlinganiselo wokulinganisa mkhulu kune-80A, kodwa kukho iintlobo ezininzi kunye neenkcukacha zeemitha zombane zesigaba esisodwa kunye nemitha yombane yesigaba sesithathu, ngoko ungakhetha njani ezi ntlobo kunye neenkcukacha?

Indlela yokukhetha imodeli yemitha yesigaba esisodwa

Iimitha zesigaba esinye nazo zineemitha zombane kunye neemitha ezihlakaniphile.Kwizindlu eziqeshisayo kunye nendawo yokuhlala apho kungekho misebenzi inzima ngakumbi, sinokukhetha iimitha zesigaba esinye sombane.Olu hlobo lwemitha lunomsebenzi oqhelekileyo wokulinganisa.Ukuba imisebenzi emininzi iyadingeka njengencopho kunye namandla entlambo, ukuhlawula ixesha, umsebenzi ohlawulelwayo, ngoko siya kukhetha iimitha ezihlakaniphile.Okwangoku, uninzi loluntu lwenza uhlaziyo ngeemitha ezihlakaniphile.

Indlela yokukhetha imodeli yemitha yombane yamanqanaba amathathu

Enyanisweni, indlela yokukhetha imitha yombane yesigaba sesithathu nayo ifuna ukujonga ukuba yeyiphi imisebenzi efunekayo.Ngokubanzi, ukuba kuphela amandla kufuneka zitshekishwe, iindibano zocweyo, iifektri ezincinci okanye iivenkile zorhwebo, kufuneka nje ukhethe imitha yombane eqhelekileyo yesigaba sesithathu sombane, njengeLinyang SM350, eneempawu ezahlukeneyo zokukhetha, ezifana ne-1.5 (6)A, 5(40)A, 10(60)A, njl., Ubuninzi bunokuba ngu-100A.Ukuba i-current yesigaba esinye idlula i-100A, kuyacetyiswa ukuba kusetyenziswe i-1.5 (6) A kunye ne-transformer kunye.Olu hlobo lwemitha ludla ngokuba yimitha yombane ophantsi kunye nenkcazo yombane engama-220/380V.

Kwi-workshop yeefektri eziphakathi kunye ezinkulu, okwangoku kukhulu, kwaye i-current-phase current kufuneka idlule i-100A.Ngaphezu koko, iifektri ezinkulu azifuni nje ukujonga isidanga sombane, kodwa kufuneka zenze uhlalutyo oluninzi lwedatha, njengohlalutyo lwegophe lomthwalo wamandla, njl. abathengi.Ngeli xesha sikhethe iimitha zethu eziziinqanaba ezithathu okanye imitha yombane enemisebenzi emininzi.Olu hlobo lwemitha yombane lunokufikelela ukuchaneka kwe-0.5 kunye ne-0.2s, kunye nomlinganiselo ochanekileyo kunye nexabiso lezoqoqosho.Olu hlobo lwemitha yombane lunemisebenzi enamandla kuneemitha ze-elektroniki apha ngasentla, njengokulinganisa ixesha lokwabelana kunye nokuhlawula, umlinganiselo wokubeka iliso kunye nemisebenzi yerekhodi yesiganeko, njl. Ngoko ke, ixabiso liya kuba phezulu.

Kwimeko yomsebenzisi wokulinganisa umbane weplantshi yombane, abasebenzisi besikhululo esingaphantsi, isigaba sesithathu semitha yombane yombane ophezulu wombane mhlawumbi siyafuneka.Kukwakho amanye amashishini ombane aphezulu, asebenzisa inqanaba lesithathu lemitha yombane yocingo oluphezulu kunye nesigaba sesithathu semitha yocingo yombane kwikhabhathi yombane ophezulu, kwaye athathe isigqibo sokuba yeyiphi enokusetyenziswa ngokusekwe kwiimfuno zesiza.Ngokubanzi, ukuba mkhulu umsinga oza kulinganiswa, kokukhona ukuchaneka okufunekayo kuphezulu kwaye ngenxa yoko, ixabiso lemitha liba phezulu.Ixabiso lemitha ye-0.2S liya kuba ngaphezu kokuphindwe kathathu kwemitha ye-0.5S.

Indlela yokukhetha imitha ehlakaniphile

Imitha elungileyo ehlakaniphile kufuneka ibe nemisebenzi emininzi enamandla, ukongeza kule misebenzi ingentla, kodwa inemisebenzi yokuchasana nokuphazamisa, ukugcinwa kwedatha, irekhodi lomcimbi, ukulinganisa okude, ukubeka iliso kusetyenziso lwamandla, kunye neminye imisebenzi, kubandakanya ukulinganisa okude. , umsebenzi wokuhlola ukusetyenziswa kwamandla.Sichitha ixabiso elingaphezulu kunemitha yombane yemveli ukuthenga iimitha kungekuphela nje ukubona amandla, kodwa ukubona ezinye iimpawu ezikrelekrele zemitha ehlakaniphile.

Inkqubo yokubeka iliso enemisebenzi yezixhobo zokubeka iliso, inokubonwa ngohlalutyo lwedatha xa ilayitiwe, xa ivala, i-voltage yayo, yangoku, amandla ombane ayaphambuka kwinto eqhelekileyo, nokuba ezi datha kunye nezixhobo zokusebenza ubushushu bugqithisile, nokuba isigaba esivulekileyo , nokuba ngenxa yeengxaki zoomatshini zisindwa, njl. njl., jonga idatha ngumnatha.

Ixabiso leemitha ze-smart ezinenkqubo yokufunda yemitha ehlawulelwa kude

Xa i-smart meter ixhotyiswe ngenkqubo yokufunda yemitha ehlawulelwayo ekude, ayiqapheli kuphela ukufundwa kwemitha okuzenzekelayo, kodwa inokutsala ukude ukutshintshela, ukuhlawula ityala kwi-intanethi, ukulungisa impazamo kunye neminye imisebenzi.Abasebenzi bolawulo lombane banokwenza ukubeka iliso kunye nokulawula iiyure ezingama-24 ngekhompyutha okanye i-APP ephathwayo, kwaye abasebenzisi banokuhlawula ngokuzenzekelayo ityala kwaye babuze malunga neentlawulo zombane.Kwangaxeshanye, yiseti yokuqokelelwa kwedatha yamandla agqibeleleyo kunye nezisombululo zenkqubo yolawulo lwepropathi, kubandakanywa neenkonzo zepropathi, ukugcinwa kobunjineli, i-APP yomsebenzisi, iiakhawunti zikawonke-wonke zabasebenzisi, ukubonelela ngenkxaso yenkonzo yelifu ngokuzenzekelayo, ukulawula iindleko zokusebenza, ukuphucula inzuzo, kunye nokunceda amashishini. ukunyuka ngokukhawuleza.
