Mastering cov kev paub yooj yim ntawm cov teeb meem siab thiab qis voltage tiav yog qhov tseem ceeb rau cov kws tshaj lij, tshwj xeeb hauv cov koom tes nrog, kis tau, thiab xa tawm. Siab thiab qis voltage tiav teeb tsa rau cov hluav taws xob hluav taws xob siab tsim los daws cov khoom siv hluav taws xob thiab paub meej txog kev ua haujlwm hluav taws xob. Hauv qab no yog cov ntsiab lus tseem ceeb kom paub thaum nkag siab txog cov kab ke no:
1. Nkag siab voltage ntau
Tsawg Voltage (LV): Feem ntau hais txog cov tshuab nrog voltages txog 1 kV (1000 v). Cov ntawv thov neeg feem ntau suav nrog cov cuab yeej hauv tsev, hluav taws xob hluav taws xob, thiab kev lag luam tshuab uas ua haujlwm ntawm cov hluav taws xob tsawg dua.
High Voltage (HV): Koom tes cuam tshuam voltages siab dua 1 kv, feem ntau yog xws li 1 kV rau ntau pua kV. HV cov tshuab tau siv hauv kev kis tau thiab faib hluav taws xob ntawm cov hluav taws xob ntev dhau thiab yuav tsum tau siv cov khoom siv tshwj xeeb vim yog cov hluav taws xob siab dua.
2. Cheebtsam ntawm cov txheej txheem tiav
Ob qho tib si loj thiab qev hluav taws xob tiav muaj ntau cov khoom tseem ceeb, txhua tus tsim los daws cov hluav taws xob tshwj xeeb. Mastering Cov Cheebtsam yog qhov tseem ceeb rau kev nkag siab li cas cov tshuab ua haujlwm.
Rau cov khoom siv voltage tsawg tiav (LV):
Circuit Court tej tog thiab fuses: Tiv thaiv cov hluav taws xob hluav taws xob los ntawm overcuent thiab luv luv voj voog.
Kev hloov pauv: Pab txhawb kev tswj hwm, tiv thaiv, thiab rho tawm ntawm hluav taws xob circuits.
PETED FARELS: Siv rau faib lub hwj chim rau ntau lub voj voog hauv cov tsev lossis chaw.
Transformers (Kauj Ruam - down): Txo qhov voltage los ntawm qib siab dua rau cov qib kev nyab xeeb rau cov kev ua haujlwm kom nyab xeeb rau kev lag luam lossis chaw nyob.
Cov khoom siv ntsuas: Siv rau kev ntsuas thiab tshuaj xyuas kev siv hluav taws xob.
Rau cov kev ntsuas siab ua tiav (HV):
HV Circuit Cour: Cov no muaj zog ntau dua li LV Circuit Courers thiab tau tsim los tuav cov hluav taws xob hnyav thiab ua yuam kev hauv siab {{voltage Systems.
Hv switchgear: Tshwj xeeb rau high - voltage ib puag ncig ib puag ncig ib puag ncig HV siv tau rau kev tiv thaiv thiab tswj hwm, ua kom muaj kev nyab xeeb hloov chaw ntawm cov kev tiv thaiv high voltages.
Transformers (kauj ruam -} Up / Kauj Ruam- down): Kauj {{- Up Transformers nce qhov kev sib txuas ntev tshaj qhov kev sib tw ntev ntev rau kev faib tawm thiab siv nyob rau theem qis dua.
Kev cais tawm thiab tsis sib thooj: Cov no tau siv los cais feem ntawm cov Circuit Court rau kev saib xyuas lossis thaum muaj kev ua yuam kev.
Busbars: Cajlaj uas faib cov hwj huam ntawm cov hluav taws xob thiab tso cai rau kev rov ua tau zoo hauv HV tshuab.
Xob laim ntes: Tiv thaiv cov kab ke los ntawm surge voltages tshwm sim los ntawm xob laim.
3. Kev Tiv Thaiv Cov Tshuab
Kev tiv thaiv cov tshuab hauv ob txhais tau thiab HV lub tshuab yog qhov tseem ceeb rau kev nyab xeeb thiab ntev ntawm cov hluav taws xob installation. Cov kab ke no yog tsim los tiv thaiv kev puas tsuaj thaum muaj hluav taws xob ua txhaum zoo li luv luv hluav taws xob lossis ntau dua. Nkag siab tiv thaiv kev sib xws li:
Overcurrent tiv thaiv: Siv rau kev tiv thaiv kev sib tw ntawm kev puas tsuaj vim yog tshaj tam sim no.
Kev tiv thaiv sib txawv: Txheeb xyuas qhov sib txawv ntawm cov roj av nkag mus thiab tawm hauv cov khoom hluav taws xob, ua rau muaj qhov sib txawv thaum muaj kev txhaum.
Ntiaj Teb Ua txhaum Tiv Thaiv: Txheeb xyuas qhov tsis muaj kev txhaum uas tshwm sim thaum cov hluav taws xob hloov mus rau hauv av, uas tuaj yeem xaiv kev nyab xeeb nyab xeeb.
Rauv Tshuab: Kev tiv thaiv kev sib tiv thaiv tau siv los saib xyuas cov xwm txheej tshwj xeeb (piv txwv li, undervoltage, undervoltage, tshaj tawm rau Cegrcuit Court tej kev txhaum lossis lwm yam kev tiv thaiv.
