Hluav taws xob yog qhov tseem ceeb ntawm peb lub neej. Txawm li cas los xij, thaum nws los txog lub chaw faib hluav taws xob, nws yuav tsum ua kom nyab xeeb thiab zoo. Nws nkag rau ntau qhov kev tswj hwm kev phom sij, uas, thaum ua tsis muaj kev nyab xeeb, tuaj yeem yooj yim tig mus rau hauv cov ntxiab yob tuag taus. Muaj qee lub sijhawm muaj xwm txheej thiab kev tsis zoo tshwm sim vim tsis muaj kev nyab xeeb ntawm cov hluav taws xob sib txawv.
Yog li, txhawm rau tswj cov qib kev nyab xeeb ntawm txhua qhov chaw faib khoom thiab chaw hloov pauv, nws yog qhov tseem ceeb rau nruab cov cuab yeej kev nyab xeeb thiab cov txheej txheem. Thaum nws muaj ntau lub tswv yim uas pab nyob rau hauv kev tiv thaiv hluav taws xob sib txuas ntawm thaj chaw nyob thiab thaj chaw, kev hloov pauv yog ib qho tseem nrov tshaj plaws vim nws cov haujlwm thiab cov yam ntxwv.
Kev tsom xam cov hloov pauv mus los ntawm qhov pom ntawm kev lag luam, kev lag luam, thiab chaw tso MV (nruab nrab hluav taws xob) kev faib tawm, nws cov haujlwm yog raws li hauv qab no:
Switchgears muab txaus ntu ntawm txoj kab ke MV kom txo qhov sib npaug ntawm qhov hluav taws xob tsis zoo thaum lub sijhawm ua haujlwm hluav taws xob ntawm cov xaim hluav taws xob thiab cov chaw fais fab.
Cov cuab yeej no pab tau hauv kev faib khoom thiab kev xa cov thau khoom thiab thau khoom lub sijhawm thau khoom thiab kev pabcuam ntawm cov sib txuas hluav taws xob.
Nws pab hauv kev tshem tawm thiab txheeb xyuas ntau yam kev txhaum thiab kev tsis ua haujlwm txuas, pab txo kev puas tsuaj kom tsawg.
Cov Hom Switchgears
Muaj ob lub ntsiab hloov pauv uas tsim nyog rau ntau yam kev lag luam, chaw nyob, thiab kev siv hluav taws xob sib txuas. Lawv yog cov
Kaw Cov Hlau Hlau: Qhov no yog cov ntaub thaiv qhov hlau zoo tshaj plaws, ua cov ntaub ntawv zoo tshaj plaws ntawm cov hlau uas muaj ntau hom ofcircuit tej fais fab. Cov khoom siv no feem ntau tso rau hauv tsev thiab siv rau nruab nrab thiab nruab nrab voltage daim ntawv thov. Raws li cov kev hloov pauv no siv sab hauv tsev, lawv yuav tsum ua kom nruj rau qhov kom zoo.
Hlau Clad Switchgear: Hom hloov hluav taws xob no feem ntau muab tso rau sab nraum lub tsev hauv cov tsev nyob thiab kev sib txuas hluav taws xob. Ua rau cov huab cua tsis haum, lawv pab tiv thaiv ntau hom kev tiv thaiv kev tiv thaiv, kev sib tsuam hluav taws xob, kev hloov pauv tam sim no thiab muaj peev xwm hloov, ntsuas zeb, thiab cov tsheb npav.
Cov Nta ntawm Hlau Clad thiab Hlau Pab Pawg Switchgear
Muaj ntau cov qauv ntawm cov switchgears uas ua rau lawv sib txawv ntawm lwm tus. Ib txhia ntawm lawv yog:
Cov kev siv ntawm Switchgears
Sib nrug los ntawm kev paub txog cov yam ntxwv sib txawv ntawm ob qhov kev hloov pauv no, nws yog ib qho tseem ceeb kom paub tias qhov twg cov switchgears feem ntau siv.
Qee qhov chaw thov ntawm cov hloov pauv no yog raws li hauv qab no:
Kev faib tawm cov fais fab: ob qho khoom siv no tau siv hauv cov nroj tsuag sib txawv thiab cov chaw ua haujlwm tshwj xeeb uas yuav tsum tau muab tshwj xeeb kom muaj zog thiab tiv thaiv ntau dhau. Cov kev hloov pauv ntawm no pab nyob rau hauv kev ua kom zoo dua qub thiab muaj kev faib hluav taws xob rau cov tshuab hauv ib chav muaj haujlwm.
Hnub ci hluav taws xob tiam: cov cuab yeej no kuj pom thov hauv ntau hom PV nruab. Raws li qhov ntsuas hluav taws xob thiab kev tswj hwm kom nruj yog qhov yuav tsum tau ua nyob rau hauv txhua lub hnub ci fais fab kev teeb tsa, cov hloov hluav taws xob no hloov cov kev hla ntawm hluav taws xob tam sim no los ntawm chav tsev tseem ceeb mus rau pawg tawm
Thaj chaw hluav taws xob faib: Cov switchgears tseem muab ntsia rau hauv cov chaw hauv zej zog sib txawv thiab ntau qhov chaw. Feem ntau, ntawm cov chaw no muaj kev sib koom ua ke ntawm ntau txoj hlua hlau thiab cov hlau ntim cov pob nyem khawm. Qhov kev sib xyaw ua ke no pab tswj lub load thiab voltage hauv thaj chaw, nrog rau kev tswj hwm txoj cai txhaum.
Cov chaw nres tsheb fais fab: Lub hauv paus loj thiab qis ntu cov fais fab xaib xav kom cov hluav taws xob no txhawm rau tiv thaiv ntau hom kev sib txuas lus hluav taws xob. Kev tsim hluav taws xob thiab kev faib tawm koom nrog kev siv ntau hom Circuit Court tej fais fab thiab cov tiv thaiv qoj ib ce, uas feem ntau tau ntim rau hauv cov hloov hluav taws xob no.
Txawm hais tias ob qho tib si cov hloov pauv no txawv kiag li ntawm lawv cov yam ntxwv thiab qhov xwm, lawv cov hom phiaj ib txwm yog los tswj thiab tswj hwm sib txawv nruab nrab voltage daim ntawv thov.
