Hauv qhov hluav taws xob, theem voltage yog lub tswv yim tseem ceeb. Nws tsis tsuas yog txiav txim siab qhov ua tau zoo thiab kev nyab xeeb ntawm kev xa hluav taws xob, tab sis tseem cuam tshuam ncaj qha rau kev xaiv thiab tsim cov khoom siv hluav taws xob. Ntawm lawv, LV (Low Voltage) thiab HV (High Voltage) yog ob theem tseem ceeb voltage, uas muaj qhov sib txawv tseem ceeb hauv ntau yam.
1. Kev txhais thiab yam ntxwv
LV (tsis tshua muaj hluav taws xob):Hauv qhov hluav taws xob, qhov hluav taws xob tsawg feem ntau yog hais txog qhov voltage ntawm AC voltage tsis tshaj 1000V lossis DC voltage tsis tshaj 1500V. Voltages nyob rau hauv no ntau yam yog dav siv nyob rau hauv tsev, coj mus muag thiab lub teeb industrial teb, xws li teeb pom kev zoo, chaw ua hauj lwm khoom, me me mechanical khoom, thiab lwm yam. Tsis tas li ntawd, LV kuj muaj kev xaiv, installation, commissioning thiab tu cov khoom siv hluav taws xob tsawg. LV system muaj cov yam ntxwv ntawm kev nyab xeeb siab, kev tswj tau yooj yim thiab kev saib xyuas, thiab yog ib qho khoom siv hluav taws xob tseem ceeb hauv lub neej niaj hnub no.
HV (High Voltage):Piv nrog rau qhov tsis tshua muaj hluav taws xob, high voltage yog hais txog qhov voltage ntawm AC voltage tshaj 1000V lossis DC voltage tshaj 1500V. High voltage hluav taws xob occupies ib tug tseem ceeb txoj hauj lwm nyob rau hauv lub hwj chim kis tau tus mob, loj industrial cov khoom, thiab industrial ntau lawm. Txij li thaum muaj hluav taws xob hluav taws xob muaj peev xwm txo tau lub zog poob thaum lub sij hawm kis tau tus mob, muab lub zog xa hluav taws xob ntau dua, thiab paub txog kev xa hluav taws xob mus ntev, nws tau dhau los ua ib feem tseem ceeb ntawm kev lag luam hluav taws xob niaj hnub no. Nyob rau hauv lub hwj chim system, high voltage hluav taws xob kuj muaj kev tsim kho thiab kev khiav hauj lwm ntawm high-voltage kis kab,substations, cov khoom siv hluav taws xob high-voltage, thiab lwm yam.
2. Qhov txawv
Voltage ntau:Qhov sib txawv tshaj plaws ntawm LV thiab HV yog qhov sib txawv ntawm lawv qhov voltage. Qhov sib txawv no ncaj qha txiav txim siab txog daim ntawv thov scenarios thiab kev ua tau zoo ntawm ob qho tib si hauv lub zog hluav taws xob.
Kev siv thaj chaw:LV systems tau siv dav hauv lub neej niaj hnub thiab kev lag luam, thaum HV ua haujlwm ntau dua hauv kev xa hluav taws xob thiab cov khoom siv loj. LV systems tsom rau kev nyab xeeb thiab yooj yim, thaum HV systems hais txog kev ua tau zoo thiab ruaj khov.
Cov khoom siv xaiv thiab tsim:Vim muaj qhov sib txawv voltage, LV thiab HV kuj muaj qhov sib txawv tseem ceeb hauv kev xaiv cov khoom siv, tsim thiab tu. Cov cuab yeej siv hluav taws xob siab feem ntau yuav tsum muaj zog rwb thaiv tsev ntau dua, kev ntsuas kev nyab xeeb thiab kev tswj ntau dua.
Kev nyab xeeb thiab kev pheej hmoo:Txawm hais tias ob qho tib si koom nrog kev xa hluav taws xob thiab kev siv, HV systems muaj kev pheej hmoo siab dua kev nyab xeeb vim lawv qhov hluav taws xob siab thiab lub zog siab. Yog li ntawd, hauv kev tsim thiab kev ua haujlwm ntawm HV systems, kev ntsuas kev nyab xeeb thiab kev ua haujlwm siab dua yuav tsum tau txais yuav.
3. Daim ntawv thov
LV daim ntawv thov:Hauv kev lag luam hauv tsev thiab kev lag luam, LV systems muab kev txhawb zog rau cov teeb pom kev zoo, cua txias, khoos phis tawj, TV thiab lwm yam khoom siv. Tsis tas li ntawd, LV kuj tau siv dav hauv kev lag luam automation tswj tshuab, xws li cov khoom siv hluav taws xob thiab kev tswj hwm ntawm PLC (Programmable Logic Controller) thiab lwm yam khoom siv.
HV daim ntawv thov:Hais txog kev xa hluav taws xob, HV systems xa hluav taws xob hluav taws xob los ntawm cov chaw tsim hluav taws xob mus rau ntau lub chaw nres tsheb thiab cov chaw faib khoom los ntawm cov kab hluav taws xob siab. Nyob rau tib lub sijhawm, HV kuj tau siv dav hauv cov khoom siv loj, xws li arc furnaces, electrolyzers thiab lwm yam khoom siv uas yuav tsum tau muaj lub zog nkag siab. Tsis tas li ntawd, HV kuj tseem ua lub luag haujlwm tseem ceeb hauv lub nraub qaum ntawm daim phiaj hluav taws xob kom ntseeg tau tias kev ua haujlwm ruaj khov thiab kev siv hluav taws xob zoo ntawm lub zog hluav taws xob.
4. Txoj kev loj hlob
Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua thiab kev loj hlob tsis tu ncua ntawm kev thov hluav taws xob, qhov hluav taws xob qis thiab hluav taws xob hluav taws xob tau txuas ntxiv txhim kho thiab txhim kho. Piv txwv li, hauv cov tshuab hluav taws xob qis, cov ntawv thov tshiab xws li cov phiaj xwm ntse thiab cov tsev ntse tau tshwm sim tas li; thaum nyob rau hauv high-voltage fais fab system, ntau qhov kev saib xyuas yog them rau kev txhim kho kev nyab xeeb thiab kev cia siab, nrog rau kev tshawb fawb thiab kev tsim kho thiab kev siv cov cuab yeej hluav taws xob tshiab.
5. Cov lus xaus
Hauv cov ntsiab lus, LV thiab HV sawv cev rau ob qhov sib txawv ntawm qhov sib txawv hauv qhov hluav taws xob, qhov hluav taws xob tsawg thiab qhov hluav taws xob siab feem. Lawv txhua tus muaj lawv tus kheej tshwj xeeb daim ntawv thov scenarios thiab cov yam ntxwv ntawm kev ua haujlwm hauv hluav taws xob. LV system ua haujlwm rau lub neej txhua hnub thiab kev lag luam nrog nws txoj kev nyab xeeb thiab yooj yim; thaum lub HV system nyob hauv txoj haujlwm tseem ceeb hauv kev xa hluav taws xob thiab cov khoom siv loj loj nrog nws cov kev ua haujlwm siab thiab ruaj khov. Nrog rau kev nce qib ntawm kev siv thev naus laus zis thiab kev loj hlob tsis tu ncua ntawm lub zog xav tau, LV thiab HV systems yuav txuas ntxiv txhim kho thiab txhim kho kom muaj kev nyab xeeb dua, muaj txiaj ntsig thiab txhim khu kev qha fais fab kev txhawb nqa rau lub neej niaj hnub.
