Ungakhetha kanjani imitha kagesi nge-current?

Kunamanani amabili amanje kuphaneli ye-smart meter, njengoba kukhonjisiwe esithombeni esingezansi.I-Linyangimithaamamaki 5(60) A. 5A iyisisekelo samanje futhi 60A isilinganiso esiphezulu samanje.Uma i-current idlula ku-60A, izolayishwa ngokweqile futhi imitha ehlakaniphile izosha.Ngakho-ke, lapho ukhetha imitha ehlakaniphile, ngakolunye uhlangothi, akufanele ibe ngaphansi kwesisekelo samanje futhi ngakolunye uhlangothi, akufanele ibe ngaphezu kwesilinganiso esiphezulu samanje.

Ake sithi izinto zethu ezijwayelekile zasendlini: ikhompuyutha engu-300W, i-350W TV, i-air conditioner engu-1500W, ifriji engu-400W, i-heater yamanzi engu-2000W.Singakwazi ukubala njengokulandelayo: okwamanje = (300+350+1500+400+2000) W/220V≈20.6A.Sizokwazi ukufaka amamitha angu-5(60)A ngenxa yokwengezwa okungenzeka kwezinto zikagesi esikhathini esizayo.

Zama ukukhetha uhlobo lwemitha ngokuya ngokusebenza kwemitha.Amamitha kagesi ahlukaniswe ngamamitha kagesi ezigaba ezintathu kanye namamitha kagesi esigaba esisodwa.Ngokuvamile, amamitha kagesi wezigaba ezintathu asetshenziswa lapho ukulinganisa kwamandla kungaphezu kuka-80A, kodwa kunezinhlobo eziningi kanye nokucaciswa kwamamitha kagesi wesigaba esisodwa kanye namamitha kagesi wezigaba ezintathu, ngakho-ke ungakhetha kanjani lezi zinhlobo kanye nokucaciswa?

Indlela yokukhetha imodeli yemitha yesigaba esisodwa

Amamitha esigaba esisodwa nawo anamamitha kagesi kanye namamitha ahlakaniphile.Ngezindlu eziqashisayo kanye nendawo yokuhlala lapho kungadingeki khona imisebenzi eyinkimbinkimbi, singakhetha amamitha wesigaba esisodwa se-electronic.Lolu hlobo lwemitha lunomsebenzi ojwayelekile wokulinganisa.Uma kudingeka imisebenzi eyengeziwe efana namandla aphezulu kanye nesigodi, ukukhokhiswa kwesikhathi, umsebenzi okhokhelwa ngaphambili, sizobe sesikhetha amamitha ahlakaniphile.Njengamanje, imiphakathi eminingi yenza ukulungisa ngamamitha ahlakaniphile.

Indlela yokukhetha imodeli yemitha kagesi yezigaba ezintathu

Eqinisweni, indlela yokukhetha imitha kagesi yezigaba ezintathu nayo idinga ukuhlola ukuthi yimiphi imisebenzi edingekayo.Ngokuvamile, uma kuphela amandla adinga ukubhekwa, ama-workshops, amafekthri amancane noma izitolo zezentengiselwano, kudingeka nje ukhethe imitha kagesi yezigaba ezintathu ezivamile, njenge-Linyang SM350, enezincazelo ezihlukahlukene zamanje ongakhetha kuzo, njenge-1.5 (6)A, 5(40)A, 10(60)A, njll., Ubuningi bungaba ngu-100A.Uma i-current yesigaba esisodwa idlula i-100A, kunconywa ukusebenzisa i-1.5(6)A kanye ne-transformer ndawonye.Lolu hlobo lwemitha ngokuvamile luyimitha ye-voltage ephansi ene-voltage ecacisiwe engu-220/380V.

Ku-workshop yamafekthri aphakathi nendawo namakhulu, lamanje likhulu ngokuqhathaniswa, futhi i-curse yesigaba esisodwa kufanele idlule i-100A.Ngaphezu kwalokho, izimboni ezinkulu azidingi ukuhlola kuphela idigri kagesi, kodwa futhi kudingeka zenze ukuhlaziya okuningi kwedatha, njengokuhlaziywa kwejika lomthwalo wamandla, njll. amakhasimende.Kulokhu sikhethe amamitha ethu ahlakaniphile ezigaba ezintathu noma imitha kagesi enemisebenzi eminingi.Lolu hlobo lwamamitha kagesi lungafinyelela ukunemba kuka-0.5s no-0.2s, ngokulinganisa okunembe kakhudlwana kanye nenani lezomnotho elihlobene.Lolu hlobo lwamamitha kagesi lunemisebenzi enamandla kakhulu kunamamitha kagesi ngenhla, njengokulinganisa isikhathi sokwabelana nokukhokhisa, ukulinganisa ukuqapha nemisebenzi yokurekhoda umcimbi, njll. Ngakho-ke, intengo izoba phezulu.

Esimeni lapho umsebenzisi olinganisa amamitha wesikhungo samandla, abasebenzisi besiteshi esincane, imitha kagesi yezigaba ezintathu enezintambo ezintathu cishe iyadingeka.Kukhona futhi amanye amabhizinisi asebenzisa amandla kagesi aphezulu, asebenzisa imitha yemitha yezintambo ezintathu ezinezintambo eziphezulu zesigaba sesithathu kanye nemitha yezintambo ezinezintambo zesigaba sesithathu ekhabetheni lamandla kagesi aphezulu, futhi anqume ukuthi iyiphi azoyisebenzisa ngokusekelwe ezidingweni zasendaweni.Imvamisa, lapho umthamo wamanje okufanele ulinganiswe ube mkhulu, kulapho ukunemba okudingekayo kuphakama khona, futhi ngenxa yalokho, intengo yemitha iba phezulu.Intengo yemitha engu-0.2S izoba ngaphezu kokuphindwe kathathu kunemitha engu-0.5S.

Indlela yokukhetha imitha ehlakaniphile

Imitha ehlakaniphile ekahle kufanele ibe nemisebenzi eminingi enamandla, ngaphezu kwemisebenzi engenhla, kodwa futhi inemisebenzi yokulwa nokukhwabanisa, ukugcinwa kwedatha, irekhodi lomcimbi, ukulinganisa okukude, ukuqapha ukusetshenziswa kwamandla, neminye imisebenzi, okuhlanganisa ukulinganisa okukude. , umsebenzi wokuqapha ukusetshenziswa kwamandla.Sichitha imali ebiza kakhulu kunemitha kagesi evamile ukuthenga amamitha hhayi nje ukubona amandla, kodwa ukubona ezinye izici ezihlakaniphile zemitha ehlakaniphile.

Isistimu yokuqapha enemisebenzi yemishini yokuqapha, ingabonakala ngokuhlaziywa kwedatha lapho ivuliwe, ukuthi ivalwa nini, amandla ayo kagesi, amanje, amandla asuka kokujwayelekile, noma ngabe le datha nezisetshenziswa zokushisa ezisebenzayo ziphakeme kakhulu, noma isigaba esivulekile. , noma ngabe ngenxa yezinkinga zemishini zithwele kanzima, njll., bheka idatha iyimeshi.

Inani lamamitha ahlakaniphile anohlelo lokufunda lwamamitha akhokhelwayo akude

Uma i-smart meter ifakwe isistimu yokufunda imitha yekhadi ekhokhelwa ukude, ayiboni kuphela ukufundwa kwemitha okuzenzakalelayo okukude, kodwa futhi ingadonsa ukude iswishi, ikhokhe isikweletu nge-inthanethi, ilungise iphutha neminye imisebenzi.Abasebenzi bokuphatha ugesi bangakwazi futhi ukuqapha nokuphatha amahora angu-24 ngekhompyutha noma i-APP yeselula, futhi abasebenzisi bangakwazi ukukhokha ngokuzenzakalelayo isikweletu futhi babuze mayelana nezindleko zikagesi.Ngasikhathi sinye, isethi yokuqoqwa kwedatha yamandla aphelele nezisombululo zesistimu yokuphathwa kwezakhiwo, okuhlanganisa izinsiza zezakhiwo, ukugcinwa kobunjiniyela, i-APP yomsebenzisi, ama-akhawunti omphakathi wabasebenzisi, ukuhlinzeka ngosekelo lwesevisi yefu oluzenzakalelayo, ukuphatha izindleko zokusebenza, ukuthuthukisa inzuzo, nokusiza amabhizinisi. ukukhuphuka ngokushesha.
