Ndi nyali zingati zomwe zingakhale mu 15 amp circuit (calculator)
Zamkatimu
Ili ndi funso losavuta lomwe lingakhale losokoneza kwambiri. Palibe yankho lotsimikizika, chifukwa kuchuluka kwa mababu mu gawo la 15 amp kumasiyana malinga ndi mtundu wa babu, mphamvu ya babu, ndi mtundu wa breaker.
Pokonza zounikira m'nyumba, chimodzi mwazinthu zoyamba chiyenera kukhala kuchuluka kwa magetsi omwe chiwembu chingathe kugwira. Nyumba iliyonse kapena nyumba iliyonse imatha kukhala ndi mawonekedwe osiyanasiyana mozungulira, koma chodziwika bwino ndi 15 amp circuit. M'nkhaniyi, ndifotokoza kuchuluka kwa mababu omwe angagwirizane ndi 15 amp circuit malinga ndi mtundu wa babu.
Ngati mukugwiritsa ntchito mababu a incandescent, mutha kugwiritsa ntchito mababu 14 mpaka 57. Ngati mukugwiritsa ntchito mababu a CFL, mutha kukwanira 34 mpaka 130, komanso mukayika mababu a LED 84 mpaka 192. Ziwerengerozi zimatanthawuza mphamvu zochepa komanso zowonjezereka. Nyali za incandescent sizimawononga ma watts oposa 100, LED - mpaka 17 watts, ndi CFL - mpaka 42 watts.
15 amp circuit Calculator
Mababu osiyanasiyana omwe mungathe kuyika mu 15 amp circuit ndi pakati ndi mababu.
Nayi tebulo la kuchuluka kwa mababu omwe mungathe kuyika mu 15 amp 120 volt dera kutengera mphamvu yamagetsi:
| MPHAMVU | Chiwerengero cha mababu |
|---|---|
| 60 W | 24 mababu |
| 40 W | 36 mababu |
| 25 W | 57 mababu |
| 15 W | 96 mababu |
Ndilowa mwatsatanetsatane pansipa.
Chiyambi - Masamu
Mabwalo onse amapangidwa kuti azitha kutengera kuchuluka kwaposachedwa, nthawi zina kuposa momwe amapangidwira (mwachitsanzo, dera la 15 amp limatha kupitilira ma amps 15 apano).
Komabe, zowononga magetsi zimachepetsa mphamvu ya dera kuti liyiteteze ku mawotchi osayembekezereka. Chifukwa chake, kuti mupewe kupunthwa wophwanya dera, "80% Rule" iyenera kutsatiridwa.
Kuchulukitsa ma 15 amps ndi 80% kumatipatsa 12 amps, yomwe ndi mphamvu yayikulu ya dera pa 15 amps.
Incandescent, CFL ndi nyali za LED
Mitundu yodziwika bwino ya nyali ndi incandescent, CFL ndi LED.
Kusiyana kwakukulu pakati pawo kuli mu mphamvu yotentha. Mababu a kuwala kwa LED samatulutsa kutentha, kotero kuti mphamvu yocheperako imafunika kuti ipange kuwala kofanana ndi mababu a incandescent ndi CFL.
Kotero, ngati mukukonzekera kukhazikitsa mababu ambiri pa 15 amp circuit breaker, njira yabwino ndikuyika mababu a LED.
Ndi mababu angati omwe angayikidwe mudera la 15 amp
Iliyonse mwa magulu atatuwa imapereka mlingo wosiyana wakuchita bwino.
Izi zikutanthauza kuti mabwalo a 15 amp ndi 15 amp circuit breakers amatha kuthana ndi mitundu yosiyanasiyana ya nyali za incandescent, LED ndi compact fulorosenti.
Powerengera, ndidzagwiritsa ntchito mphamvu yayikulu komanso yochepa yamtundu uliwonse wa nyali. Mwanjira iyi mudzadziwa mitundu yosiyanasiyana ya mababu omwe amatha kukhazikitsidwa mumayendedwe a 15 amp.
Tiyeni tiwerenge.
Nyali za incandescent
Monga tafotokozera pamwambapa, mababu a incandescent amafunikira mphamvu zambiri kuposa mababu ena. Izi zikutanthauza kuti mutha kuyika mababu ocheperako kuposa ma CFL ndi ma LED.
- Mphamvu zochepa za nyali za incandescent ndi 25 watts.
Pakali pano ikuyenda mozungulira ndi 12 amps (malinga ndi lamulo la 80%). Chifukwa chake titachita masamu, timapeza: Mphamvu ikufanana ndi nthawi yamagetsi:
P=V*I=120V*12A=1440W
Tsopano, kuti muwerenge kuchuluka kwa mababu omwe mungagwiritse ntchito, ndiyenera kugawa madzi a dera ndi mphamvu ya babu limodzi:
1440W / 25W = 57.6 mababu
Popeza simungathe kukwanira mababu 0.6, ndikuzungulira mpaka 57.
- Mphamvu yayikulu 100W
Pakali pano adzakhalabe chimodzimodzi, i.e. 12 ampe. Choncho, mphamvu ya dera idzakhalanso chimodzimodzi, i.e. 1440 Watts.
Kugawa mphamvu ya dera ndi mphamvu ya babu limodzi, ndimapeza:
1440W / 100W = 14.4 mababu
Popeza simungagwiritse ntchito mababu 0.4, ndikuzungulira mpaka 14.
Chifukwa chake mitundu ya mababu a incandescent omwe mutha kuwayika mudera la 15 amp adzakhala pakati pa 14 ndi 57.
Nyali za CFL
Mphamvu za nyali za CFL zimayambira pa 11 mpaka 42 watts.
- Mphamvu yayikulu 42W.
Mphamvu yamagetsi yamagetsi idzakhalabe yofanana ndi ya nyali za incandescent, i.e. 12 amperes. Choncho, mphamvu ya dera idzakhalanso chimodzimodzi, i.e. 1440 Watts.
Kugawa mphamvu ya dera ndi mphamvu ya babu limodzi, ndimapeza:
1440W / 42W = 34.28 mababu
Popeza simungagwiritse ntchito mababu 0.28, ndikuzungulira mpaka 34.
- Mphamvu zochepa 11 watts.
Kugawa mphamvu ya dera ndi mphamvu ya babu limodzi, ndimapeza:
1440W / 11W = 130.9 mababu
Popeza simungagwiritse ntchito mababu 0.9, ndikuzungulira mpaka 130.
Chifukwa chake mitundu ya mababu a incandescent omwe mutha kuwayika mudera la 15 amp adzakhala pakati pa 34 ndi 130.
Nyali za LED
Mphamvu za nyali za LED zimasiyana kuchokera ku 7.5W mpaka 17W.
- Ndiyamba ndi mphamvu yayikulu, yomwe ndi 17 watts.
Mphamvu yamagetsi yamagetsi idzakhalabe yofanana ndi ya nyali za incandescent ndi CFLs, ndiko kuti, 12 amperes. Choncho, mphamvu ya dera idzakhalanso chimodzimodzi, i.e. 1440 Watts.
Kugawa mphamvu ya dera ndi mphamvu ya babu limodzi, ndimapeza:
1440W / 17W = 84.7 mababu
Popeza simungathe kukwanira mababu 0.7, ndikuzungulira mpaka 84.
- Kwa mphamvu yochepa, yomwe ndi 7.5 watts.
Kugawa mphamvu ya dera ndi mphamvu ya babu limodzi, ndimapeza:
1440W / 7.5W = 192 mababu
Chifukwa chake mitundu ya mababu a incandescent omwe mungayike mudera la 15 amp atha kukhala mababu 84 mpaka 192.
Onani zina mwazolemba zathu pansipa.
- Momwe mungayesere nyali ya fulorosenti ndi multimeter
- Momwe mungalumikizire soketi ya babu
- Zingwe za LED zimawononga magetsi ambiri
