Delta / Delta yog siv nyob rau hauv ntau industrial installations, thaum Delta / Wye yog cov feem ntau kev teeb tsa. Wye / Delta yog siv nyob rau hauv high voltage kis tau tus mob, thiab Wye / Wye tsis tshua siv vim muaj peev xwm tsis sib npaug.
Ua raws li qhov xav tau, qhov txawv ntawm Delta thiab Wye yog dab tsi?
Qhov sib txawv ntawm Delta thiab Wye Kev sib txuas Delta configuration siv tsuas yog peb-theem conductors, whereas wye ua -connected systems nqa ib tug plaub nruab nrab neeg xyuas pib uas yog feem ntau grounded tab sis tej zaum sab laug floating. Tsis zoo li hauv delta kev twb kev txuas, tag nrho peb loads yog kev cob cog rua ntawm ib tug nruab nrab point nyob rau hauv wye ua kev sib txuas.
Delta thiab Wye fais fab yog dab tsi? A delta - wye ua transformer yog ib hom peb-theem hluav taws xob zog transformer tsim uas ua haujlwm delta -txuas windings ntawm nws thawj thiab wye ua / hnub qub txuas windings ntawm nws theem nrab. Lub nruab nrab xaim tuaj yeem muab rau wye ua tso zis sab. Lub sij hawm sib npaug yog delta - hnub qub transformer.
Ntawm no, yog 480 volts Delta lossis Wye?
Rau ib 4 80v system yog tias nws yog a wye ua koj yuav muaj ib tug 277 hluav taws xob mus rau tag nrho peb theem nruab nrab. Lwm yam voltages rau grounded conductor yuav yog ib delta system, tab sis lawv tuaj yeem sib txawv qee yam nyob ntawm qhov chaw nws yog av, lossis yog tias nws yog av txhua.
Puas yog 208 Delta lossis Wye?
A WYE configuration yog lwm qhov teeb meem. Muaj 208 Volts ntawm kab-rau-kab. Muaj 120 Volts ntawm kab-rau-nruab nrab ( 208 V / 1.73 = 120 V). Qhov txiaj ntsig pom tseeb yog tias koj tau txais peb-120 V kab rau lub teeb pom kev zoo uas tsis yog ob qho uas koj tau txais hauv DELTA system saum toj no.

Puas yog zaub ntau ntau?
Lub plural ntawm zaub yog 'zaub' nwslef. Tab sis Peb yuav siv lo lus ' zaub' thaum peb tham txog cov lej uas suav tau. Ex - nws tau nqa ob qho zaub xwb. Tsis yog Nws coj zaub
Puas yog dawb lossis xim dub cuam tshuam lub teeb ntau dua?
Ib yam khoom dub absorbs tag nrho cov wavelengths ntawm lub teeb thiab hloov mus rau hauv tshav kub, yog li cov khoom tau sov. Ib yam khoom dawb qhia txog txhua qhov wavelengths ntawm lub teeb, yog li lub teeb tsis hloov mus rau hauv tshav kub thiab qhov kub ntawm qhov khoom tsis nce ntxiv
Puas yog cov txiaj ntsig ntawm fracking ntau dua cov nqi?
Fracking tau upended American zog system. Nws tau coj cov txiaj ntsig zoo rau lub tebchaws nyob rau hauv cov nqe lus ntawm tus nqi qis zog, kev ruaj ntseg zog ntau dua, txo cov pa phem, thiab tsawg dua cov pa roj carbon emissions (txawm hais tias nws qhov kev cuam tshuam ntev ntawm cov pa roj carbon emissions tsis meej)
Yog vim li cas thermal khiav ntawm atmospheric gas ntau yooj yim dua los ntawm lub hli dua los ntawm lub ntiaj teb?
Yog vim li cas thermal khiav ntawm atmospheric gas ntau yooj yim dua los ntawm lub hli dua los ntawm lub ntiaj teb? Vim lub hli lub ntiajteb txawj nqus muaj zog npaum li lub ntiaj teb. Cov pa oxygen tso tawm los ntawm lub neej raug tshem tawm ntawm qhov chaw los ntawm cov tshuaj lom neeg nrog cov pob zeb nto kom txog thaum lub pob zeb nto tuaj yeem nqus tsis tau ntxiv
Vim li cas cov kab mob feem ntau tsim cov xeeb ntxwv ntau dua li muaj sia nyob?
Cov kab mob tsim cov xeeb ntxwv ntau dua li qhov muaj sia nyob. Cov kab mob tuaj yeem tuag los ntawm ntau yam ua rau: kab mob, kev tshaib plab, thiab noj, thiab lwm yam. Ib puag ncig tsis tuaj yeem txhawb nqa txhua yam kabmob uas yug los. Ntau tus tuag ua ntej lawv muaj peev xwm rov tsim dua
