Nkag siab qhov txawv ntawm High Voltage thiab Low Voltage hauv Cov Hluav Taws Xob

Hauv kev lag luam hluav taws xob, cov ntsiab lus "high voltage" thiab "tsis tshua muaj hluav taws xob" feem ntau ntsib, tab sis lawv feem ntau ua rau tsis meej pem rau cov neeg tsis paub txog thaj chaw. Kev nkag siab txog qhov sib txawv ntawm ob pawg no yog qhov tseem ceeb rau kev nyab xeeb thiab kev ua haujlwm ntawm cov tshuab hluav taws xob. Qhov blog no tsom kom paub meej qhov sib txawv ntawm qhov hluav taws xob siab thiab tsis tshua muaj hluav taws xob, tshawb xyuas lawv cov ntsiab lus, kev siv, kev xav txog kev nyab xeeb thiab cov qauv kev cai.

Cov ntsiab lus ntawm high voltage thiab low voltage yog txiav txim siab los ntawm ib puag ncig uas lawv siv. Feem ntau hais lus, tsis tshua muaj hluav taws xob yog hais txog cov tshuab hluav taws xob uas muaj qhov hloov pauv tam sim no (AC) voltages qis dua 1,000 volts (1 kV) thiab ncaj qha tam sim no (DC) voltages qis dua 1,500 volts (1.5 kV). Cov piv txwv ntawm cov ntawv siv hluav taws xob tsawg muaj xws li cov kab hluav taws xob hauv tsev, teeb pom kev zoo, thiab cov khoom siv me me. Hauv qhov sib piv, qhov hluav taws xob siab feem ntau yog hais txog cov tshuab ua haujlwm ntawm qhov hluav taws xob saum toj no. Cov tshuab hluav taws xob siab feem ntau yog siv rau hauv kev xa hluav taws xob thiab kev sib txuas sib txuas uas hluav taws xob yuav tsum tau thauj mus ntev nrog kev poob qis. Qhov sib txawv tsis yog kev kawm xwb; Nws muaj kev cuam tshuam loj rau kev tsim, kev ua haujlwm thiab kev saib xyuas cov tshuab hluav taws xob.

Kev siv cov tshuab siab thiab qis siab ntxiv qhia txog lawv qhov sib txawv. Cov tshuab hluav taws xob tsawg feem ntau yog siv rau hauv cov chaw nyob thiab kev lag luam kom muaj zog rau cov khoom siv niaj hnub thiab teeb pom kev zoo. Cov tshuab no tau tsim los kom yooj yim siv thiab nyab xeeb, feem ntau suav nrog kev tiv thaiv kev tiv thaiv xws li cov hluav taws xob hluav taws xob thiab cov fuses kom tsis txhob muaj overloading. High-voltage systems, ntawm qhov tod tes, yog qhov tseem ceeb rau kev xa hluav taws xob zoo ntawm cov chaw tsim hluav taws xob mus rau cov chaw siv hluav taws xob thiab qhov kawg rau cov neeg siv khoom. Cov tshuab no xav tau cov cuab yeej tshwj xeeb xws li transformers thiab insulators los tswj cov hluav taws xob muaj zog thiab ua kom muaj kev nyab xeeb. High-pressure system infrastructure yog complex thiab kim, qhia txog qhov yuav tsum tau rau advanced technology thiab nruj kev ruaj ntseg raws tu qauv.

Kev txiav txim siab txog kev nyab xeeb yog qhov tseem ceeb thaum tham txog cov tshuab siab thiab tsis tshua muaj siab. Cov tshuab hluav taws xob tsawg, thaum feem ntau muaj kev nyab xeeb dua rau kev siv txhua hnub, tseem ua rau muaj kev pheej hmoo, tshwj xeeb tshaj yog tias lawv tsis tau teeb tsa lossis khaws cia kom raug. Yog tias tsis ua raws li cov qauv kev nyab xeeb, hluav taws xob poob qis, luv luv Circuit Court, thiab hluav taws kub yuav tshwm sim. Txawm li cas los xij, cov tshuab hluav taws xob siab ua rau muaj kev pheej hmoo ntau dua. Qhov ua tau ntawm hluav taws xob poob siab, teeb meem arc flash, thiab cov khoom siv tsis ua haujlwm yuav tsum tau ntsuas kev nyab xeeb nruj. Cov neeg ua haujlwm nrog cov tshuab hluav taws xob siab yuav tsum tau txais kev cob qhia tshwj xeeb thiab ua raws li cov txheej txheem kev nyab xeeb nruj, suav nrog kev siv cov cuab yeej tiv thaiv tus kheej (PPE) thiab cov txheej txheem kaw / tagout. Cov koom haum tswj hwm xws li Kev Tswj Xyuas Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv (OSHA) thiab National Electrical Code (NEC) muab cov lus qhia los ua kom muaj kev nyab xeeb ntawm cov tshuab hluav taws xob siab thiab hluav taws xob tsawg.

Cov qauv kev tswj hwm ua lub luag haujlwm tseem ceeb hauv kev txhais thiab tswj cov tshuab hluav taws xob siab thiab qis. Ntau cov qauv thoob ntiaj teb thiab lub teb chaws muaj nyob rau hauv kev faib cov qib voltage thiab tsim kom muaj kev nyab xeeb. Piv txwv li, International Electrotechnical Commission (IEC) muab cov lus qhia rau kev faib cov hluav taws xob rau hauv ntau pawg, cuam tshuam li cas cov tshuab hluav taws xob thoob ntiaj teb tau tsim thiab ua haujlwm. Kev ua raws li cov qauv no yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov tshuab hluav taws xob. Hauv ntau qhov kev txiav txim siab, kev teeb tsa hluav taws xob yuav tsum tau kuaj xyuas thiab lees paub kom ua tau raws li cov cai tswj hwm no, ntxiv rau qhov tseem ceeb ntawm kev nkag siab qhov sib txawv ntawm qhov siab thiab qis voltage.

Qhov sib txawv ntawm qhov siab thiab tsis tshua muaj hluav taws xob hauv cov tshuab hluav taws xob yog ntau dua li cov lus hais; nws npog qhov tseem ceeb ntawm kev nyab xeeb, kev siv, thiab kev tswj hwm kev ua raws cai. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau txhua tus neeg koom nrog hauv kev tsim, kev teeb tsa, lossis kev saib xyuas cov tshuab hluav taws xob. Raws li kev siv thev naus laus zis txuas ntxiv mus, qhov tseem ceeb ntawm kev ua raws li cov qauv kev nyab xeeb thiab kev tswj hwm tsuas yog nce ntxiv, yog li cov kws tshaj lij thiab cov neeg ua haujlwm zoo ib yam yuav tsum paub txog cov nuances ntawm cov tshuab siab thiab qis. Los ntawm kev nkag siab tob ntawm peb cov kev nkag siab ntawm cov ntsiab lus no, peb tuaj yeem txhim kho kev nyab xeeb, kev ua tau zoo, thiab kev ntseeg siab ntawm peb cov khoom siv hluav taws xob.
