Txawm hais tias koj yog tus kws tshaj lij lossis tsis yog, thiab yog tias koj txiav txim siab hloov cov xaim hauv koj lub tsev, txawm tias nyob rau hauv ntu "lub thawv - hloov - lub teeb qhov muag teev", koj yuav tsum paub cov kev cai tseem ceeb ntawm PUE (tag nrho Cov ntawv sau tseg - "Cov Cai rau kev teeb tsa hluav taws xob", uas yog, cov txheej txheem siv tau rau txhua qhov kev teeb tsa hluav taws xob thiab lub zog hluav taws xob). Nws yog los ntawm no uas koj tuaj yeem tau txais cov ntaub ntawv hais txog seb xoom lossis theem mus rau qhov hloov pauv.
Lub xov tooj twg ua rau lub teeb hloov?
Txawm hais tias hauv qee qhov chaw koj tuaj yeem pom tias qhov hloov mus rau "zero", qhov no tsis yog qhov qub. Vim tias ib qho kev hloov pauv yuav tsum ua kom tawg theem. Yog tias qhov xoom lossis theem ntawm qhov hloov pauv, feem ntau yuav, qee tus neeg ua haujlwm tsis muaj hmoo tau "poked" nyob rau hauv cov xaim ntawm chav tsev no, lossis thawj zaug cov hlau nruab nrab tsis tau siv raws li tus qauv.
Cov xim dab tsi yuav tsum muaj nyob hauv cov xaim hluav taws xob ntawm chav tsev
Txhua tustus neeg xyuas pib yuav rau kev teeb tsa hluav taws xob xaim yuav tsum muaj cov tub ntxhais nrog lub xiav (xiav) braid. Nws yog nws uas pom zoo kom siv rau hauv lub network raws li ib tug nruab nrab hlau. Yog hais tias lub tsev apartment muaj ib tug thib peb hlau - ncaj qha grounding, nws yog pom zoo kom khiav ib tug daj-ntsuab hlau rau nws. Tag nrho lwm cov xov hlau (nws tuaj yeem yog xim dawb, xim av, xim dub, thiab lwm yam) yog siv los ua theem nqa khoom. Yog li rau lo lus nug seb qhov hloov pauv puas cuam tshuam rau theem lossis xoom, cov lus teb yuav tsis meej - theem, thiab cov xaim no yuav tsis xiav (xiav) thiab tsis ntsuab.
Yog cov xaim sib xyaw hauv koj chav tsev, nws txhais tau tias tsis yog cov kws tshaj lij tau koom nrog kev teeb tsa hluav taws xob hauv nws thiab, feem ntau, nws twb tau kho dua lawm.
Qhov tseem ceeb ntawm hluav taws xob
Cia peb sim piav qhia txog kev ua haujlwm ntawm hluav taws xob hauv cov lus siv tau tshaj plaws. Txawm hais tias los ntawm cov lus qhia ntawm physics, peb paub tias qhov tseem ceeb ntawm hluav taws xob yog qhov uas theem ib txwm zoo li raug tso tawm mus rau xoom. Nws yog nyob nruab nrab ntawm cov cab kuj ntawm hluav taws xob thiab cov kwj hauv av uas muaj ntau yam khoom siv nrog rau hauv Circuit Court. Tom qab ntawd tso tawm tshwm sim hauv lawv, yuam lawv ua haujlwm.
Tshwj xeeb, qhov no yog li cas lub filament lossis diode circuit ua haujlwm hauv lub teeb pom kev zoo. Lub filament lossis diode Circuit Court muaj nws tus kheej tsis kam, uas yog sib npaug kom lub teeb, thaum lub network kaw los ntawm lawv, tsis txhob hlawv tawm, tab sis pib ci. Thiab qhov tseeb, nws tsis muaj teeb meem dab tsi cov hlau yog haum rau qhov hloov pauv - xoom lossis theem, yog tias xoom nkag mus rau lub teeb nws tus kheej los ntawm ib qho kev sib cuag, thiab theem ntawm lwm qhov, nws yuav ua haujlwm li cas. Nyob ntawmKev ua tau zoo ntawm cov cuab yeej yuav tsis cuam tshuam rau txhua txoj hauv kev. Qhov no yog rau kev ruaj ntseg nkaus xwb.
Vim li cas "theem" thiab tsis "zero"?
Peb tau los ze los teb cov lus nug ntawm seb xoom lossis theem mus rau qhov hloov pauv thiab vim li cas. Qhov hloov pauv qhib ntu ntawm lub network uas lub teeb ua haujlwm. Thiab nws cuam tshuam hauv cov keyboards yooj yim tsuas yog ib qho ntawm cov xov hlau uas dhau los ntawm nws. Qhov thib ob hlau tseem txuas ncaj qha rau lub teeb. Yog tias nyob rau hauv koj cov ntaub ntawv xoom dhau los ntawm kev hloov, ces ib theem yog txuas ncaj qha mus rau lub chandelier, uas txhais tau hais tias txawm nrog ib tug yooj yim hloov ntawm lub teeb, lub ntaus ntawv yuav shock koj.
Yog tias qhov hloov pauv qhib theem, ces xoom ncaj qha mus rau lub chandelier ntawm lub thawv. Qhov no txhais tau hais tias yog tias qhov hloov pauv nyob rau hauv lub xeev qhib (tawm), theem tsis tau muab rau lub cuab yeej lawm, vim nws cuam tshuam los ntawm kev hloov nws tus kheej, thiab hloov lub teeb yuav muaj kev nyab xeeb.
Kev teeb tsa kom raug ntawm qhov hloov pauv nrog kev hloov ntawm cov xov hlau mus rau nws thiab mus rau chandelier
Thaum peb txheeb xyuas cov lus nug ntawm cov xaim twg - "theem" lossis "zero" yuav tsum tuaj rau qhov hloov pauv kom ua tau raws li PUE cov qauv, peb xav paub seb daim duab kos ntawm lub tsev hluav taws xob hauv tsev yuav zoo li cas zoo li, uas yuav txiav txim siab qhov kev ua haujlwm ntawm cov khoom siv hluav taws xob. Ib zaug ntxiv, cia peb piav qhia txhua yam hauv cov lus yooj yim (rau kev nyab xeeb vim li cas, txhua txoj haujlwm cuam tshuam nrog kev teeb tsa lossis kho cov xaim hluav taws xob yuav tsum tau nqa tawm nrog lub tshuab nruab nrab muab tua hauv lub ntsiab keyboards).
- Rau txoj hlua kom raugLos ntawm qhov ze tshaj plaws hlws ris lub thawv, peb yuav tsum muaj ob lub rooj vag - ib tug mus rau qhov hloov, ib tug mus rau lub chandelier.
- Yuav ua li cas txuas lub "theem - xoom" hloov, uas yog, qhov hloov pauv zoo li qub? Peb muab ib daim ntawm ob-xaim hlau. Peb hla nws los ntawm sab qhov ntawm lub thawv, mus rau lub rooj vag mus rau qhov hloov. Peb kuj hla lub cable los ntawm sab qhib ntawm lub thawv hloov.
- Peb pub ib qho tseem ceeb rau sab laug lub davhlau ya nyob twg ntawm qhov hloov pauv, lwm qhov mus rau sab xis. Nyob rau hauv lub thawv, ib qho ntawm cov cores yog pub rau theem xaim. Ib qho tseem pub dawb rau tam sim no.
- Peb tau txais dab tsi? Tam sim no qhov tam sim no los rau qhov hloov pauv thiab nyob rau hauv qhov chaw kaw ntawm qhov hloov pauv rov qab mus rau lub thawv. Nws tseem yuav txuas lub network rau lub teeb pom kev zoo.
- Wb hais tias peb chandelier yog tsim rau ib lub teeb. Tom qab ntawd ib txwm ob-core cable yuav ua. Peb hla nws los ntawm sab qhov ntawm lub thawv ua rau lub chandelier, kaw nws hauv lub rooj vag thiab txuas mus rau lub chandelier terminals.
- Nyob rau hauv lub thawv, peb txuas ob-core cable mus rau lub chandelier raws li hauv qab no: peb pub ib tug tub ntxhais mus rau lub rov qab dawb tub ntxhais - lub theem los ntawm kev hloov, lwm yam yog powered mus rau lub ntsiab xoom nyob rau hauv lub thawv..
Txoj kev sib sau ua ke. Tam sim no, paub txog qhov twg xaim mus rau qhov hloov, "zero" lossis "theem", koj tau ua ib ntu ntawm lub network uas ua kom cov khoom siv teeb pom kev zoo tag nrho.
In xaus, qee qhov nuances
Nyob rau hauv peb tsab xov xwm, peb tsom mus rau ib tug yooj yim network uas tsis muab rau ib tug thib peb hlau - grounding. Peb kuj pib los ntawm qhov tseeb tias peb muaj ib qho yooj yim chandelier,tsim rau 1 lub teeb. Yog li ntawd, peb qhov kev hloov pauv yog qhov yooj yim - ib qho yuam sij.
Nyob hauv av, koj yuav tsis sib tov. Koj tsuas yog yuav tsum tau siv peb- lossis ntau tshaj-ntxhais cable thiab ib txwm siv lub zog daj-ntsuab rau hauv av, uas yog, mus rau lub davhlau ya nyob twg mus rau rooj plaub.
Thiab nyob rau hauv rooj plaub ntawm cov keyboards ntau, koj yuav tsum pov ob lossis ntau cov xov hlau (nyob ntawm seb muaj pes tsawg tus yuam sij hauv qhov hloov) tawm ntawm lub thawv mus rau qhov hloov. Ib yam yuav tsum tau ua nrog lub hwj huam mov ntawm lub chandelier. Tsis muaj teeb meem ntau npaum li cas los ntawm kev hloov mus rau chandelier, yuav muaj ib qho xoom nyob rau hauv nws, nws lub davhlau ya nyob twg yuav raug qhia cais. Koj tseem tuaj yeem taug kev los ntawm cov xov hlau. Zero in instruments yeej ib txwm xiav (lub teeb xiav).
