Circuit Court tiv thaiv tus neeg xyuas pib (nce hu ua ' c.p.c ua .') yog ib qhov system ntawm conductors koom ua ke tag nrho cov raug conductive qhov chaw thiab txuas lawv mus rau lub ntsiab earthing davhlau ya nyob twg. Hais lus nruj me ntsis, lub sij hawm suav nrog lub ntiaj teb tus neeg xyuas pib nrog rau cov khoom sib txuas ua ke equipotential.
Tsis tas li ntawd, lub hom phiaj ntawm CPC nyob rau hauv ib lub voj voog yog dab tsi?
Cov Circuit Court tiv thaiv conductor ( CPC ) yog siv los muab kev tiv thaiv los ntawm hluav taws xob poob siab thiab tso cai rau cov tam sim no txaus kom cov khoom tiv thaiv tuaj yeem mus. Ntau lub teb chaws thiab thoob ntiaj teb cov qauv txhais cov kev cai rau CPC . ib tug ruaj los yog liab qab insulated conductor. lub sheath los yog armouring ntawm ib tug cable.
Qhov thib ob, koj ua li cas rau CPC? Muab tias lub cpc ua yog xam los ntawm kev siv lub rooj 54.7 los yog qhov sib npaug adiabatic. siv 54.7a cpc ua ntawm 2.5mm2 yuav tsum tau. Siv cov kab zauv adiabatic S = 100, t = 5 vib nas this, K- 115, muab ib cpc ua ua 1,9mm2.
Dab tsi yog CPC hauv cov teeb pom kev zoo?
Teeb pom kev zoo circuits tsis muaj lub ntiaj teb ( CPC ) Thaum ntxov xyoo 1960 ntau lub tsev tau xaim tsis muaj lub ntiaj teb xaim (tam sim no hu ua a Circuit Kev Tiv Thaiv Tus Cwj Pwm lossis CPC ) hauv teeb pom kev zoo Circuit Court.
Dab tsi ntawm cable yog ntxaib thiab lub ntiaj teb?
Twin thiab Earth Cable. Ntxaib thiab lub ntiaj teb cable muaj ob tus kheej insulated tam sim no nqa conductors thiab ib tug uninsulated Circuit Court tiv thaiv conductor. Twin thiab Earth cable yog cov kab ntau tshaj plaws siv rau kev xaim hluav taws xob niaj hnub no. Lub plhaub yog grey ( PVC ) los yog dawb rau cov pa hluav taws xob qis (OHLS).

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Kcmil cable yog dab tsi?
Kcmil-Hauv North American hluav taws xob kev lag luam, conductors loj dua 4/0 AWG yog feem ntau txheeb xyuas los ntawm cheeb tsam nyob rau hauv phav phav ncig mils (kcmil), qhov twg 1 kcmil = 0.5067 mm². Ib ncig mil yog thaj tsam ntawm ib lub xaim ib mais hauv txoj kab uas hla. MCM-ib txhiab mais
Dab tsi yog qhov kev ncua deb ntawm fiber ntau optic cable?
2km ua Tsis tas li ntawd, qhov kev ncua deb ntawm ib hom fiber ntau yog dab tsi? Thaum ua haujlwm nrog nyob deb mus txog 2 km, siv multimode kho qhov muag - fiber ntau kab. Singlemode optical - fiber ntau cable, txawm li cas los xij, muaj ntau bandwidth-intensive thiab muaj peev xwm tsawg dua rau modal dispersion thiab suab nrov dua li multimode kho qhov muag - fiber ntau cable, txhais mus rau lub peev xwm kis tau tus mob tshaj lub nyob deb kev txwv ntawm multim
Dab tsi yog cable inductance?
Hauv electromagnetism thiab electronics, inductance yog qhov nyiam ntawm cov khoom siv hluav taws xob los tawm tsam kev hloov pauv ntawm cov hluav taws xob tam sim no ntws los ntawm nws. Nws yog aproportionality yam uas nyob ntawm geometry ntawm circuitconductors thiab cov magnetic permeability ntawm cov khoom nyob ze
