British Standard BS 7671: 2008 txhais cov high voltage raws li ib qho voltage sib txawv ntawm conductors uas siab tshaj 1000 VAC los yog 1500 V ripple-free DC, los yog ib qho voltage sib txawv ntawm ib Tus neeg xyuas pib thiab lub ntiaj teb uas siab dua 600 VAC lossis 900 V ripple-free DC.
Cov kab hluav taws xob siab AC lossis DC?
Cov kab sib kis feem ntau yog high-voltage peb-theem alternating tam sim no (AC), txawm tias ib theem AC qee zaum siv hauv kev tsheb ciav hlau hluav taws xob. High-voltage direct-current (HVDC) thev naus laus zis yog siv rau kev ua haujlwm zoo dua nyob rau qhov deb heev (feem ntau pua mais).
Vim li cas yog qhov hluav taws xob siab?
“Qee tus neeg xav txog dab tsi saum 1000 V raws li qhov hluav taws xob siab. Cov kev txwv tau hais meej meej, txawm li cas los xij, hauv IEC 60038 tus qauv: qhov hluav taws xob qis yog mus txog 1000 V, qhov nruab nrab voltage yog los ntawm 1000 V txog 35 kV, thiab qhov hluav taws xob siab yogtshaj 35 kV.
pes tsawg volts yog 3 theem?
Tam sim no cia kuv muab cov ntsiab lus yooj yim rau koj. Rau peb-theem, koj txuas kab 1 mus rau kab 2 thiab tau txais 208 volts.
Is 11kV HV or LV?
Kev sib txuas hluav taws xob tshiab - High Voltage (HV) lossis loj Low Voltage (LV) khoom siv. Kev tsim hluav taws xob tsim hluav taws xob sib txuas ntawm 11kV txog 132kV.

Puas siv hluav taws xob hauv qhov hluav taws xob tuaj yeem siv rau ntawm qhov loj?
Txawm hais tias tsawg dua, lwm hom kev siv hluav taws xob hauv av tuaj yeem siv los muab ntau lub zog ntau dua. Tapping qhov chaw ntawm cov dej kub faus rau hauv qab lub ntiaj teb saum npoo tuaj yeem muab cua sov rau cov neeg coob coob, thiab tsim kom muaj zog txaus los tsim hluav taws xob loj.
Puas yog hluav taws xob hluav taws xob muaj ob qhov xwm txheej?
EM hluav taws xob yog lub npe vim nws muaj hluav taws xob thiab sib nqus teb uas ib txhij oscillate hauv cov dav hlau sib koom ua ke rau ib leeg thiab rau kev taw qhia ntawm kev nthuav tawm los ntawm qhov chaw. ✓ Electromagnetic tawg muaj ob qhov xwm txheej:
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Cadmium puas yog qhov zoo ntawm cov hluav taws xob thiab hluav taws xob?
Vim nws qhov ua tau zoo raws li tus neeg xyuas hluav taws xob, cadmium feem ntau siv hauv electroplating thiab hauv roj teeb. Tsis tas li ntawd, cadmium thiab cov kev daws teeb meem ntawm nws cov tebchaw yog tshuaj lom thiab yuav tsum tau ua tib zoo saib xyuas.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
