Muaj qhov yooj yim xam qhov sib npaug rau xam watt siv rau cov khoom siv hluav taws xob. Txhua yam koj yuav tsum paub yog tus naj npawb ntawm amperes (amps) thiab tus naj npawb ntawm cov volts rau lub cuab yeej. Nkag siab txog watts yog qhov tseem ceeb vim tias nws tuaj yeem pab koj txuag nyiaj thiab lub zog.
Cov kauj ruam
Txoj Kev 1 ntawm 3: Siv Lej los txiav txim siab txog Watts
Kauj Ruam 1. Txiav txim xyuas cov watts hauv lub hwj chim
Koj yuav tsum paub cov amps thiab cov volts hauv lub zog siv. Txhawm rau txiav txim siab wattage, siv cov lej sib npaug yooj yim. Ampere (lossis amps) yog tus nqi hluav taws xob siv. Qhov ntsuas hluav taws xob ntsuas lub zog lossis siab ntawm hluav taws xob.
- Tus naj npawb ntawm watts yog sib npaug rau amps sib npaug ntawm volts. Qhov ntawd yog nws! Hauv lwm lo lus, watt = amp X volt. Qee zaum koj yuav pom cov mis no sau ua W = A X V.
- Piv txwv li, yog tias qhov tam sim no yog 3 amps (3A) thiab qhov hluav taws xob yog 110V, koj sib npaug 3 los ntawm 110, kom tau 330W (watts). Cov mis yog P = 3A X 110V = 330 W (nrog P sawv rau lub zog).
- Qhov no yog vim li cas watts qee zaum hu ua volt-amps. Cov ntsuas hluav taws xob feem ntau muaj cov amps sau rau ntawm lawv cov tes. Qhov no yog qhov siab tshaj plaws uas lub Circuit Court tuaj yeem siv ua ntej qhov kev tawm mus ncig. Koj tseem tuaj yeem txiav txim siab ob qho tib si volts thiab amps los ntawm kev saib ntawm cov ntawv lossis hauv phau ntawv ua haujlwm. Koj tuaj yeem saib cov duab sib xws rau cov cuab yeej siv (feem ntau cov khoom siv me me thiab cov teeb pom kev zoo hauv tsev xav tau cov khoom siv hluav taws xob uas nyob ntawm 15-20 amps thiab qhov loj dua yog 20 txog 60. Txawm li cas los xij, feem ntau cov khoom siv sab hauv tsev tshaj plaws yog ntsuas rau 120 volts thiab ua haujlwm nrog 12 lossis tsawg dua amps. Cov cuab yeej loj xws li cov kab thiab cov tshuab ziab khaub ncaws xav tau lub zog ntau dua thiab txuas nrog cov kab hluav taws xob uas txuas mus rau 240 volt zog thiab tuaj yeem kos 20 txog 40 amps nyob ntawm seb muaj pes tsawg yam. Cov tsev thaiv tsev feem ntau yog 120 lossis 240 volts hauv North America.
Kauj Ruam 2. Txiav txim seb amps lossis volts zoo ib yam
Koj tuaj yeem ua tus lej sib npaug hauv thim rov qab. Piv txwv, cia peb hais tias koj muaj AC 24-40 fais fab mov. Qhov no txhais tau tias koj lub hwj chim muaj 24 volts thiab 40 watts.
- Lub zog siv hluav taws xob tuaj yeem muab 1.6 amps. Cov mis siv yog 40-? X 24. Yog li, koj yuav faib 40 rau 24 kom tau 1.6.
- Nov yog lwm qhov laj thawj uas koj yuav xav tau ua qhov no. Cia peb hais tias koj xav xam tawm cov watts siv los ntawm lub qab nthab ntxuam, thiab daim ntawv lo ntawm lub kiv cua hais tias tus kiv cua siv qee tus naj npawb ntawm amps. Tom qab ntawd koj tuaj yeem pom tus lej ntawm cov hluav taws xob uas siv los ntawm kiv cua qab nthab (los ntawm kev hu xov tooj rau cov chaw tsim khoom lossis tsuas yog saib hauv online), muab ob tus lej, thiab kwv yees kwv yees ntawm wattage xav tau los khiav lub qab nthab kiv cua.
Kauj Ruam 3. Txiav txim siab tus neeg tiv thaiv wattage
Yog tias koj xav paub wattage ntawm tus tiv thaiv, koj yuav tsum paub qhov voltage (V) thiab qhov tam sim no (paub zoo li kuv). Qhov no hu ua Ohm txoj cai.
- Cov lej sib npaug yog qhov sib npaug ntawm qhov tam sim no, qhia ua W = V X I.. Qee zaum koj yuav pom cov qauv sau nrog tus P rau lub zog.
- Cov mis tau nyuaj dua thaum lub zog hloov pauv nyob rau lub sijhawm. Nws koom nrog siv lub sijhawm kom tau qhov nruab nrab. Nws nyuaj rau suav, thiab rau qhov ntsuas no, koj yuav tsum siv cov cuab yeej tshwj xeeb hu ua wattage meter.
Txoj Kev 2 ntawm 3: Siv Cov Cuab Yeej los Txiav Txim Wattage
Kauj Ruam 1. Nrhiav lub laij lej online
Muaj ntau qhov peev txheej hauv online uas siv cov laij lej los txiav txim siab txog watts. Lawv yuav ua tus qauv rau koj.
- Cov peev txheej zoo li no feem ntau nug koj kom nkag mus rau tus lej volts, thiab tus lej amps. Tom qab ntawd koj raug hais kom ntaus lub "xam" khawm kom tau lub watts.
- Nco ntsoov, txawm li cas los xij, cov lej hauv online tsis yog qhov tseeb vim tias txhua lub cuab yeej yuav txawv me ntsis hauv nws lub zog xav tau.
- Qee qhov chaw hauv online yuav muab cov watt uas koj xav tau yog tias koj nyem rau ntawm yam khoom siv, xws li TV lossis computer computer. Cov chaw qee zaum muaj cov kab kos uas teev cov watts siv los ntawm ntau yam khoom siv, los ntawm cov tub yees rau hauv cov thawv.
Kauj Ruam 2. Txheeb xyuas koj lub cuab yeej
Koj tuaj yeem xam tawm pes tsawg watts cov cuab yeej xav tau los ntawm kev nrhiav cov phaj ntawv.
- Nrhiav qhov no nyob tom qab ntawm koj lub cuab yeej. Nws zoo li yuav teev pes tsawg volts, amps, thiab watts koj xav tau los txhawb koj lub cuab yeej. Koj tuaj yeem pom cov ntaub ntawv no thim rov qab ntawm lub tshuab. Lossis koj tuaj yeem pom cov wattage teev rau ntawm daim ntawv teev npe.
- Wattage metres ntsaws rau hauv cov khoom siv, thiab lawv qhia koj qhov tseeb ntawm lub zog uas lub cuab yeej xav tau los khiav. Lub zog ntawm cov khoom siv yuav txawv nyob ntawm nws qhov teeb tsa. Piv txwv li, lub xov tooj cua yuav siv ntau lub watts yog tias koj tig lub ntim kom siab.
Txoj Kev 3 ntawm 3: Kawm Ntau Ntxiv Txog Lub Hwj Chim
Kauj Ruam 1. Nkag siab tias vim li cas watts tseem ceeb
Lub zog hauv watts yog tus nqi uas lub zog tsim lossis siv. Ntau lub tuam txhab hluav taws xob yuav sau nqi rau koj raws li pes tsawg watts ntawm lub zog koj siv. Lub watt yog qhov tseem ceeb npaum li cas lub zog siv khoom siv.
- Rated watts yog tus nqi ntawm watts xav tau los ua kom cov cuab yeej ua haujlwm. Piv txwv li, tub yees feem ntau xav tau 500 watts kom khiav tau zoo. Koj yuav xav paub lub watts hauv koj lub tsev yog tias koj tab tom sim ua kom muaj zog ntau dua, ntxiv cov hnub ci ci, lossis siv lub tshuab hluav taws xob.
- Lub zog hluav taws xob los hauv AC thiab DC tam sim no. AC txhais tau tias hloov pauv tam sim no; cov hluav taws xob tam sim no thim rov qab cov lus qhia thiab siv ntau zaus hauv tsev thiab chaw ua haujlwm. DC txhais tau tias ncaj qha tam sim no, thiab nws txhais tau tias tam sim no tsuas yog taug kev hauv ib qho kev taw qhia. Koj yuav pom nws hauv cov khoom xws li cov roj teeb pob.
- Surge watts txhais tau hais tias tus nqi ntawm watts xav tau kom tau txais lub cuab yeej pib los ntawm kev ua rau nws lub cev muaj zog lossis lub tshuab ua kom txias. Piv txwv li, nws yuav siv 2, 000 watts los pib lub cav thiab tshuab cua txias.
Kauj Ruam 2. Ua kom muaj zog ntau dua
Watts yog lub hauv paus tseem ceeb ntawm lub zog (hluav taws xob, tshuab, lossis cua sov). Qhov laj thawj watts teeb meem yog vim tias koj tuaj yeem txhim kho kev siv hluav taws xob yog tias koj nkag siab lawv.
- Txo koj cov watts, thiab koj yuav txhim kho kev siv hluav taws xob thiab txuag nyiaj. Nov yog qhov piv txwv. Cia peb hais tias koj tab tom yuav lub teeb, thiab ib qho yog 100 watts thiab lwm qhov yog 23 watts. Yog tias 100 Watt teeb yog pheej yig dua, koj yuav xav tias nws yog qhov kev yuav khoom zoo dua. Txawm li cas los xij, dhau sijhawm, 23 Watt teeb yuav txuag koj nyiaj.
- Ua qhov yooj yim rho tawm los txiav txim siab qhov sib txawv ntawm watt. Hauv qhov no, uas yog 77 watts (100-23). Cov tuam txhab hluav taws xob feem ntau yuav tsub koj siv kilowatts. Txhawm rau kom paub tus naj npawb ntawm kilowatts, siv tus naj npawb ntawm watts faib los ntawm 1, 000. Tom qab ntawd suav tus lej kilowatts sib npaug los ntawm koj lub sijhawm siv. Qhov no yog kilowatt/hr. Tom qab ntawd, siv kilowatt/hr thiab muab tus lej ntawd los ntawm tus nqi ntawm koj lub zog. Nov yog koj li nqi txhua xyoo.
- Piv txwv li, cia peb hais tias koj muaj 10 lub teeb. Lawv yog txhua 100 watts. 10 X 100 = 1,000,000 watts. 1, 000 Watts faib los ntawm 1, 000 = 1 kW. Cia peb hais tias koj tau siv 2, 000 teev ntawm lub zog. Yog li, 1kW X 2, 000 teev hauv ib xyoos = 2, 000 kwh. Cia peb hais tias koj lub tuam txhab hluav taws xob tsub koj 10 xees rau txhua kilowatt teev. Koj yuav siv 2, 000 kwh X.10 = $ 200, Qhov ntawd nws yuav raug nqi koj li cas los siv cov qij rau xyoo.
Yees duab - Los ntawm kev siv qhov kev pabcuam no, qee cov ntaub ntawv yuav raug muab qhia rau YouTube
Lub tswv yim
Nco ntsoov tso cai rau me me ntawm "phantom" wattage rau txhua lub cuab yeej txuas rau hauv Circuit Court/inverter. Ntau yam khoom siv hluav taws xob txuas ntxiv siv hluav taws xob thaum lawv raug tua. Qhov no tshwj xeeb tshaj yog txhua yam uas qhia pom lub teeb LED thaum nws tawm
Lus ceeb toom
- Muab ntau yam khoom siv ntau dhau rau ntawm qhov hloov pauv yuav ua rau lub zog qis rau cov khoom siv. Qhov no tuaj yeem ua rau lawv puas, lossis ua rau lawv kaw.
- Yog tias koj rub lub zog ntau dhau los ntawm inverter, koj yuav pheej hmoo inverter hlawv tawm.
- Cov lej tsuas yog kwv yees, yog li yog tias koj xav tau tshwj xeeb thiab raug wattage nyeem koj yuav tsum tau siv lub ntsuas cua wattage.
