Mangaki amalambu angaba ku-15 amp circuit (isibali)
Okuqukethwe
Lo ngumbuzo olula ongadida kakhulu. Ayikho impendulo eqondile, njengoba inani lama-bulb kusekethe ye-amp engu-15 lizohluka kuye ngohlobo lwe-bulb, i-bulb wattage, kanye nohlobo lwe-circuit breaker.
Lapho uthuthukisa uhlelo lokukhanyisa endlini, omunye wemicabango yokuqala kufanele kube inombolo yezibani isikimu esingasingatha. Indlu ngayinye noma isakhiwo singaba ne-amperage ehlukile kusekethe, kodwa okuvame kakhulu yisekethe engu-15 amp. Kulesi sihloko, ngizochaza ukuthi mangaki amalambu angangena kusekethe engu-15 amp kuye ngohlobo lwesibani.
Uma usebenzisa izibani ze-incandescent, ungasebenzisa ama-14 kuya ku-57 awo. Uma usebenzisa ama-CFL bulbs, ungangena ku-34 kuya ku-130, futhi uma ufaka ama-LED angama-84 kuya kwangu-192. Lezi zibalo zibhekisela emandleni amancane naphezulu. Izibani ze-incandescent azisebenzisi ngaphezu kwama-watts angu-100, i-LED - kufika kuma-watts angu-17, kanti ama-CFL - kufika kuma-watts angu-42.
I-Calculator yesifunda engu-15 amp
Uhla lwamalambu okukhanya ongalufaka kumjikelezo we-amp angu-15 luphakathi namalambu okukhanya.
Nali ithebula lenombolo yamalambu okukhanya ongawabeka kusekethe engu-15 amp 120 volt ngokusekelwe emanzini:
| AMANDLA | Inani lama-bulb |
|---|---|
| 60 W | 24 amalambu |
| 40 W | 36 amalambu |
| 25 W | 57 amalambu |
| 15 W | 96 amalambu |

Isingeniso - Mathematics
Wonke ama-circuits aklanyelwe ukuphatha inani elithile lamanje, ngezinye izikhathi ngaphezu kwalokho aklanyelwe ukuphatha (isibonelo, isekethe engu-15 amp ingaphatha ama-amps angaphezu kuka-15 wamanje).
Kodwa-ke, ama-circuit breaker kagesi akhawulela amandla esekethe ukuze ayivikele ekukhuphukeni kwamandla okungalindelekile. Ngakho-ke, ukuze ugweme ukukhubekisa i-circuit breaker, kufanele kulandelwe i- "80% Rule".
Ukuphindaphinda ama-amps angu-15 ngo-80% kusinika ama-amps angu-12, okuwumthamo omkhulu wesekethe kuma-amps angu-15.
Amalambu e-Incandescent, CFL nama-LED
Izinhlobo ezivame kakhulu zamalambu yi-incandescent, i-CFL ne-LED.
Umehluko omkhulu phakathi kwazo usemandleni ashisayo. Amalambu okukhanya e-LED awakukhiqizi ukushisa, ngakho-ke amandla amancane kakhulu adingekayo ukuze kukhiqizwe inani lokukhanya elilingana ne-incandescent kanye nama-CFL.
Ngakho-ke, uma uhlela ukufaka amalambu amaningi ku-15 amp circuit breaker, inketho engcono kakhulu ukufaka ama-LED ama-bulb.
Mangaki amalambu angafakwa kusekethe engu-15 amp
Isigaba ngasinye kulezi ezintathu sinikeza izinga elihlukile lokusebenza ngempumelelo.
Lokhu kusho ukuthi ama-circuits angu-15 amp kanye nama-circuit breaker angu-15 angakwazi ukuphatha izinombolo ezihlukene zamalambu e-incandescent, ama-LED kanye namalambu e-fluorescent ahlangene.
Ukuze uthole izibalo, ngizosebenzisa amandla aphezulu kanye nobuncane bohlobo ngalunye lwesibani. Ngale ndlela uzokwazi uhla lwamalambu angafakwa kusekethe engu-15 amp.
Asibale.
Ama-incandescent ama
Njengoba kushiwo ngenhla, izibani ze-incandescent zidinga amandla amaningi kunamanye amalambu. Lokhu kusho ukuthi ungafaka ama-incandescent bulb ambalwa kunama-CFL nama-LED.
- Amandla amancane amalambu e-incandescent angama-watts angama-25.
Isilinganiso esiphezulu samanje esigeleza kumjikelezo singama-amps angu-12 (ngokomthetho we-80%). Ngakho-ke ngemuva kokwenza izibalo, sithola: Amandla alingana nezikhathi ze-voltage zamanje:
P=V*I=120V*12A=1440W
Manje, ukubala ukuthi mangaki ama-bulb ozowasebenzisa, ngidinga ukuhlukanisa ukugeleza kwesekhethi ngamanzi e-bulb eyodwa:
1440W / 25W = 57.6 ama-bulb
Njengoba ungeke ukwazi ukulingana nama-bulb angu-0.6, ngizohlanganisa afinyelele ku-57.
- Amandla aphezulu angu-100W
Ubuningi bamanje buzohlala bufana, i.e. 12 amp. Ngakho-ke, amandla wesifunda nawo azohlala efana, okungukuthi i-1440 watts.
Ukuhlukanisa amandla esekethe ngamandla esibani esisodwa, ngithola:
1440W / 100W = 14.4 ama-bulb
Njengoba ungeke ukwazi ukusebenzisa ama-bulbs angu-0.4, ngizohlanganisa aze afike ku-14.
Ngakho-ke ububanzi bama-incandescent bulb ongawaxhuma kumjikelezo we-amp angu-15 buzoba phakathi kuka-14 no-57.
Izibani ze-CFL
Amandla amalambu e-CFL asuka ku-11 kuye ku-42 watts.
- Amandla aphezulu angu-42W.
Ubuningi bamanje besistimu kagesi buzohlala bufana nelambu le-incandescent, okungukuthi i-12 amperes. Ngakho-ke, amandla wesifunda nawo azohlala efana, okungukuthi i-1440 watts.
Ukuhlukanisa amandla esekethe ngamandla esibani esisodwa, ngithola:
1440W / 42W = 34.28 ama-bulb
Njengoba ungeke ukwazi ukusebenzisa ama-bulbs angu-0.28, ngizohlanganisa aze afike ku-34.
- Amandla amancane angama-watts angu-11.
Ukuhlukanisa amandla esekethe ngamandla esibani esisodwa, ngithola:
1440W / 11W = 130.9 ama-bulb
Njengoba ungeke ukwazi ukusebenzisa ama-bulbs angu-0.9, ngizohlanganisa aze afike ku-130.
Ngakho-ke ububanzi bama-incandescent bulb ongawaxhuma kumjikelezo we-amp angu-15 buzoba phakathi kuka-34 no-130.
Ama-LED
Amandla amalambu e-LED ahluka kusuka ku-7.5W kuya ku-17W.
- Ngizoqala ngamandla amakhulu, okungama-watts angu-17.
Umthamo omkhulu wamanje wesistimu kagesi uzohlala ufana nalawo amalambu e-incandescent nama-CFL, okungukuthi, ama-amperes angu-12. Ngakho-ke, amandla wesifunda nawo azohlala efana, okungukuthi i-1440 watts.
Ukuhlukanisa amandla esekethe ngamandla esibani esisodwa, ngithola:
1440W / 17W = 84.7 ama-bulb
Njengoba ungeke ukwazi ukulingana nama-bulb angu-0.7, ngizohlanganisa afinyelele ku-84.
- Ngamandla amancane, angama-watts angu-7.5.
Ukuhlukanisa amandla esekethe ngamandla esibani esisodwa, ngithola:
1440W / 7.5W = 192 ama-bulb
Ngakho-ke ububanzi bama-incandescent bulb ongawabeka kumjikelezo we-amp angu-15 bungaba ama-84 kuya kwangu-192.
