Peb cov kab hluav taws xob ntawm cov kab hluav taws xob, uas yog cov kab theem, kab nruab nrab, thiab cov xaim hauv av, ua lub luag haujlwm tseem ceeb hauv kev xa hluav taws xob. Lawv sib koom ua ke kom muaj kev nyab xeeb ntawm kev xa hluav taws xob hluav taws xob thiab kev ua haujlwm ntawm cov khoom siv ib txwm muaj. Txawm nyob hauv tsev, kev lag luam, kev lag luam, lossis lwm yam kev lag luam, cov cables no yog ib qho tseem ceeb ntawm lub zog hluav taws xob. Kev nkag siab txog lawv txoj haujlwm thiab kev siv yog qhov tseem ceeb rau kev ua kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm lub zog hluav taws xob.
1. Phase Hlau
Cov kab theem, tseem hu ua cov xaim kub lossis cov xaim nyob, yog thawj kab hauv lub hwj huam qaum. Nws feem ntau yog xim dub lossis xim liab, thiab qee zaum nws tuaj yeem yog lwm cov xim ci rau kev txheeb xyuas yooj yim. Lub luag haujlwm tseem ceeb ntawm ib theem kab yog xa tawm tam sim no, hloov hluav taws xob los ntawm lub zog hluav taws xob (xws li lub chaw tsim hluav taws xob lossis chaw nres tsheb) mus rau cov khoom siv hluav taws xob. Qhov no yog ib tug nyob hlau lub luag hauj lwm rau muab rau pem hauv ntej tam sim no los tsav lub lag luam ntawm cov khoom siv.
Qhov voltage ntawm theem kab tuaj yeem yog ib-theem lossis peb-theem, nyob ntawm seb lub zog tshwj xeeb. Nyob rau hauv ib-theem hluav taws xob tshuab, tsuas muaj ib theem kab, feem ntau yog siv rau cov tsev nyob thiab cov tsev lag luam me. Hauv kev lag luam thiab kev lag luam loj, peb-theem fais fab tshuab feem ntau yog siv, nrog peb theem kab staggered los ntawm 120 degrees ntawm ib leeg. Qhov kev teeb tsa no yuav pab kom muaj kev sib kis tau zoo dua thiab muaj zog dua.
2. Tsis siv neeg hlau
Cov hlau nruab nrab yog qhov thib ob ntawm cov hlua hluav taws xob, feem ntau yog xim dawb lossis lub teeb grey. Lub luag haujlwm ntawm cov xaim nruab nrab yog muab ib lub voj voog xa tawm tam sim no los ntawm cov khoom siv hluav taws xob rov qab mus rau lub zog hluav taws xob, ua kom tiav hauv Circuit Court. Nws yog ib qho ntxiv rau theem kab, siv los rov qab tam sim no ntau dhau (xws li rov qab tam sim no hauv AC) rov qab mus rau lub zog hluav taws xob los xyuas kom muaj qhov sib npaug ntawm Circuit Court.
Nyob rau hauv ib-theem fais fab system, feem ntau tsuas muaj ib tug nruab nrab hlau, thiab nyob rau hauv peb-theem systems, kuj muaj ib tug xwb. Qhov hluav taws xob ntawm cov kab nruab nrab feem ntau yog ze rau xoom vim tias nws txoj haujlwm tseem ceeb yog muab lub voj voog rau tam sim no, tsis yog kev sib kis. Nws ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv luv luv Circuit Court thiab tiv thaiv cov khoom siv thiab cov neeg ua haujlwm.
3. Cov Hlau hauv av
Cov xaim hauv av yog qhov thib peb hauv cov hlua hluav taws xob, feem ntau yog xim ntsuab lossis ntsuab daj. Lub luag haujlwm tseem ceeb ntawm cov xaim hauv av yog muab kev tiv thaiv kev nyab xeeb coj mus rau hauv av thiab tiv thaiv hluav taws xob thiab khoom puas tsuaj. Thaum muaj kev txhaum tshwm sim hauv cov cuab yeej siv, cov xaim hauv av kom nyab xeeb coj mus rau hauv av tam sim no, tsis yog tso cai rau nws dhau los ntawm tib neeg lub cev lossis lwm yam khoom siv hluav taws xob, txhawm rau txo cov kev phom sij.
Grounding xov hlau tseem pab kom ruaj khov voltage, txo cov electromagnetic cuam tshuam, thiab tiv thaiv cov cuab yeej los ntawm lwm yam xws li xob laim thiab surges. Nws plays lub luag haujlwm tseem ceeb hauv kev siv hauv av thiab kev tiv thaiv cov khoom siv hluav taws xob.
Cov xaim hauv av kuj tseem siv rau hauv av ntawm cov tsev kom ntseeg tau tias cov khoom siv hluav taws xob thiab cov neeg ua haujlwm hauv lub tsev muaj kev tiv thaiv tag nrho. Cov txheej txheem hauv av no feem ntau suav nrog cov av electrodes, grounding conductors, thiab grounding electrodes, uas qhia cov hauv av tam sim no thiab ua kom muaj kev nyab xeeb ntawm lub zog hauv lub tsev.
Cov ntawv thov hauv ntau qhov chaw
Peb cov cables no tau siv dav hauv ntau qhov chaw. Nov yog qee qhov piv txwv:
Kev siv hluav taws xob nyob hauv tsev: Hauv cov tsev nyob, ib theem hluav taws xob feem ntau yog siv, qhov twg theem, nruab nrab, thiab hauv av xaim tag nrho ua lub luag haujlwm tseem ceeb. Cov theem kab xa hluav taws xob hluav taws xob mus rau cov khoom siv hauv tsev, cov kab nruab nrab muab lub voj voog, thiab cov xaim hauv av ua kom muaj kev nyab xeeb.
Cov ntawv thov kev lag luam thiab kev lag luam: Hauv cov tsev lag luam thiab kev lag luam, peb theem hluav taws xob feem ntau yog siv los ua kom tau raws li qhov xav tau ntau dua. Cov tshuab no tseem suav nrog theem, nruab nrab, thiab hauv av xaim, tab sis siv rau hauv cov khoom siv loj thiab ntau dua.
Cov khoom siv hluav taws xob: Ntau yam khoom siv hluav taws xob, xws li khoos phis tawj, TV, thiab lub tshuab suab, kuj siv cov cables kom tau txais lub zog thiab kev ruaj ntseg.
Kev faib hluav taws xob: Hauv cov hluav taws xob faib hluav taws xob, cov cables feem ntau loj dua thiab tuab dua kom tiv taus cov khoom siv tam sim no, tseem suav nrog cov theem, nruab nrab, thiab cov xaim hauv av.
Cov teeb liab teeb liab: Cov teeb liab teeb liab thiab cov teeb liab kev tsheb ciav hlau kuj tseem siv cov kab hluav taws xob no los xyuas kom muaj kev ua haujlwm zoo thiab ua kom muaj kev nyab xeeb tsim nyog.
