Hluav taws xob grounding yog tseem ceeb vim hais tias nws muab cov qib siv hluav taws xob tiv thaiv uas tag nrho lwm qhov hluav taws xob hauv qhov system raug tsim thiab ntsuas.
Ua li no, lub hom phiaj ntawm qhov hluav taws xob hauv av yog dab tsi?
Raws li NEC, lub lub hom phiaj ntawm kev sib txuas ib hluav taws xob system rau lub cev hauv av ( ntiaj teb ) yog txhawm rau txwv qhov hluav taws xob los ntawm cov xwm txheej xob laim thiab kev sib cuag nrog cov kab hluav taws xob ntau dua, thiab kuj rau kev ruaj ntseg voltage.
Tsis tas li ntawd, dab tsi yog grounding nyob rau hauv hluav taws xob? Hluav taws xob grounding yog ib txoj hauv kev thaub qab uas muab txoj hauv kev hloov pauv rau qhov tam sim no ntws rov qab mus rau hauv av yog tias muaj teeb meem hauv cov kab hluav taws xob. Nws pab txhawb kev sib txuas ntawm lub cev ntawm cov av thiab cov hluav taws xob cov khoom siv thiab cov khoom siv hauv koj lub tsev.
Ntxiv mus, hluav taws xob hauv av ua haujlwm li cas?
A hauv av hlau muab cov khoom siv los yog hluav taws xob ntaus txoj hauv kev nyab xeeb kom tso tawm hluav taws xob ntau dhau. Ib hluav taws xob Circuit Court cia siab rau ob qho tib si zoo thiab tsis zoo hluav taws xob. A hauv av xaim siv hluav taws xob uas tau tsim thaum lub sijhawm ua haujlwm tsis zoo thiab xa tawm sab nraud ntawm koj lub tsev rov qab mus rau hauv av.
Yuav ua li cas yog tias koj tsis txuas hauv av xaim?
Cov khoom siv yuav ua haujlwm ib txwm tsis muaj av xaim vim nws tsis yog ib feem ntawm txoj kev coj uas muab hluav taws xob rau cov khoom siv. Hauv qhov tsis muaj av xaim , kev poob siab tej yam kev mob feem ntau yuav tsis ua rau lub breaker mus txawv tebchaws tshwj tsis yog lub Circuit Court muaj ib tug hauv av txhaum interrupter nyob rau hauv nws.

Vim li cas kuv lub tshuab hluav taws xob tsis tsim hluav taws xob?
Feem ntau ua rau lub tshuab hluav taws xob portable tsis tsim hluav taws xob yog los ntawm kev poob ntawm cov hlau nplaum seem. Generators ua hauj lwm los ntawm kev txav hluav taws xob conductors los ntawm magnetic teb. Koj lub tshuab hluav taws xob tsis muaj hlau nplaum. Thaum cov hlau nplaum seem ploj lawm, lub tshuab hluav taws xob yuav tsis muaj zog thaum pib
Vim li cas cov hluav taws xob sab nraud tsuas yog suav nrog hauv daim duab kos duab hluav taws xob?
Atoms nrog 5 los yog ntau tshaj valence electrons tau electrons tsim ib tug tsis zoo ion, los yog anion. Vim li cas thiaj li cov hluav taws xob sab nraud tsuas yog cov uas suav nrog hauv daim duab orbital filling? lawv tsuas yog cov uas koom nrog cov tshuaj tiv thaiv thiab kev sib raug zoo. 2s orbital nyob deb ntawm lub nucleus txhais tau tias nws muaj zog ntau dua
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Vim li cas cov kab hluav taws xob ua hluav taws xob yog perpendicular rau equipotential nto?
Txij li cov kab hluav taws xob hluav taws xob taw qhia radiallyaway ntawm tus nqi, lawv yog perpendicular mus rau cov kab hluav taws xob. Lub peev xwm yog tib yam nyob rau hauv txhua txoj kab uas muaj peev xwm, txhais tau hais tias tsis muaj haujlwm yuav tsum tau txav mus los ntawm ib qho ntawm cov kab no
