1. Dab tsi yog ib qho kev ntsuas ib ntu?
Ib qho kev ntsuas ib ntu yog cov khoom siv hluav taws xob siv rau ntsuas ib leeg-theem hloov pauv tam sim no (AC). Nws feem ntau muaj ob lub xov hlau: ib theem xaim xaim thiab ib qho nruab nrab hlau. Cov theem qib xaim yog lub luag haujlwm rau kis tau tam sim no, thaum lub nruab nrab xaim pab ua txoj kev xa rov qab rau qhov tam sim no. Ib leeg mais feem ntau muaj voltage ntawm 230 volts thiab ib zaus ntawm 50 hz thiab tau siv dav hauv tsev thiab cov chaw lag luam me.
Vim nws cov qauv yooj yim thiab tus nqi qis, ib leeg-theem metres yog cov cuab yeej uas nyiam rau muaj hluav taws xob muaj hluav taws xob. Nws muaj peev xwm ua tau raws li lub zog xav tau ntawm kev tsim khoom hauv tsev neeg, TV, ua tub yees, thiab cua txias.
2. Qhov zoo ntawm ib-theem meters
Haum rau kev siv hauv tsev: Ib feem-theem-theem me me yog tsim rau cov kev yuav qes thiab yog qhov zoo rau cov chaw nyob thiab cov chaw lag luam me.
Ib qho yooj yim ua haujlwm: lawv yog lub teeb pwm thiab kev cog lus, ua rau lawv yooj yim rau nruab thiab tswj.
Nqi-siv tau: Ib theem-theem me me yog qhov pheej pheej yig los siv vim lawv cov kev yuav tsum muaj hwj chim tsawg.
Kev sib kis tau: Ib Leeg-theem-theem meters muaj peev xwm tuaj yeem xa hluav taws xob hauv cov xwm txheej hauv cov xwm txheej qis hauv cov xwm txheej qis.
3. Dab tsi yog peb-theem meter?
Lub peb-theem ntsuas yog lub ntsuas hluav taws xob siv los ntsuas peb-theem lwm yam tam sim no. Nws muaj peb theem xov hlau thiab ib lub hlau nruab nrab, nrog theem txawv ntawm 120 degrees ntawm txhua theem hlau. Peb-theem meters feem ntau yog 415 volts, muaj peev xwm ntawm lub rooj sib tham siab siab muaj zog, thiab tau siv dav hauv kev lag luam thiab cov chaw lag luam loj.
Muaj ob hom kev teeb tsa configuration rau peb-theem metres: hnub qub (Y-hom) thiab peb-hom). Lub Hnub Qub Kev teeb tsa xav tau ib qho nruab nrab ntawm cov hlau thiab hauv av xaim, thaum lub sijhawm peb lub voos kev hloov tsis ua.
4. Qhov zoo ntawm peb-theem meters
Kev txhawb nqa siab: Peb-theem meters muaj peev xwm muab lub zog txaus rau cov cuab yeej muaj hnyav uas tsis tas yuav muaj cov pib ntxiv.
Kev sib kis tau du rau cov yam ntxwv ntawm peb-theem hluav taws xob, lub hwj huam kis tau ruaj khov thiab muaj zog.
Economical thiab txuag: Peb-theem meters yuav tsum muaj cov ntaub ntawv tsawg dua, txo cov nqi sib kis tau ploj thiab cov nqi.
Kev ntseeg siab: txawm hais tias ib theem tsis ua tiav, lwm cov theem ob tuaj yeem txuas ntxiv muab lub zog muab txuas ntxiv.
| 5. Lub ntsiab sib txawv ntawm ib leeg-theem thiab peb-theem meters | ||
| Nta | PEEM Meter | Peb-theem Fais Meter |
| Tus naj npawb ntawm cov xov hlau | 2 (1 theem + 1 nruab nrab) | 4 (3 phales + 1 nutral) |
| Muaj ntau ntau | 230 volts | 415 volts |
| Muaj cov xwm txheej muaj feem xyuam | Lub Tsev thiab Kev Lag Luam Me | Muaj thiab loj ua lag luam |
| Kev Sib Kis Zog | Qi | Siab dua |
| Network nyuaj siab | Yooj yim | Nyuaj |
| Kev ua txhaum kev ua txhaum | Ib qho kev txhaum ib zaug xwb yuav ua rau lub zog hluav taws xob | Ib theem tsis ua hauj lwm tsis cuam tshuam rau ob ntu |
6. Yuav ua li cas xaiv cov meter ntsuas haum?
Seb puas yuav xaiv ib qho kev ntsuas ib ntu lossis theem peb-theem peb nyob ntawm feem ntau ntawm lub zog xav tau thiab cov xwm txheej:
Lub tsev thiab cov chaw lag luam me me: Vim yog qhov kev thov hluav taws xob qis dua, ib theem me me metres yog kev lag luam thiab kev xaiv ua haujlwm ntau dua.
Kev lag luam loj thiab cov chaw lag luam loj: rau cov zog xav tau, peb-theem meters tuaj yeem muab kev txhawb nqa hluav taws xob ruaj khov thiab muaj zog hluav taws xob ruaj khov.
Ib qho ntxiv, cov nqi nruab, kev sib kis hluav taws xob ua tau zoo thiab cov cuab yeej sib xyaw yuav tsum tau txiav txim siab.
7. Ntsiab lus
Ib leeg mais mais thiab peb-theem metres txhua tus muaj lawv tus kheej tshwj xeeb zoo thiab muaj cov xwm txheej muaj feem xyuam. Ib leeg mais mais yog qhov zoo tagnrho rau lawv cov kev lag luam yooj yim thiab kev lag luam nrog lawv cov peev xwm kev txhawb nqa thiab kev ntseeg siab.
Txawm hais tias lub 'meter' metre koj xaiv, nkag siab txog nws cov yam ntxwv thiab cov hnoos qeev ntawm daim ntawv thov yog tus yuam sij rau kev ua tiav kev tswj hwm hluav taws xob zoo. Nrog rau kev txhim kho cov kab ntse, meter technology yog txhim kho tas li, muab cov neeg siv tau yooj yim dua thiab yooj yim dua thiab yooj yim lub zog hluav taws xob daws.
