Cov qauv twg yuav tsum thauj khoom tawg hloov ua raws li?

Thaum nws los txog rau kev hloov pauv hloov pauv, ua kom lawv ua raws li cov qauv kev lag luam uas lees paub yog qhov tseem ceeb rau kev nyab xeeb thiab txhim khu kev qha hauv high-voltage kis thiab faib tshuab. Hauv tsab xov xwm no, kuv yuav rhuav tshem cov qauv tseem ceeb uas thauj khoom hloov pauv yuav tsum tau ntsib thiab hais txog qee cov lus nug feem ntau nyob ib puag ncig lawv cov haujlwm thiab kev tswj hwm kev ua raws cai.

Dab tsi yog Cov Txheej Txheem Kev Nyab Xeeb Tseem Ceeb rau Load Break Switches?

Load break keyboards yog qhov tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm cov khoom siv hluav taws xob. Rau kev hloov pauv hloov kom raug cai thiab ua haujlwm nyab xeeb, nws yuav tsum ua raws li ntau yam qauv tsim los ntawm ntau lub koom haum. Thoob ntiaj teb, cov qauv no feem ntau yog tswj hwm los ntawm International Electrotechnical Commission (IEC) thiab, hauv qee thaj tsam, los ntawm National Electrical Manufacturers Association (NEMA).

1. IEC 62271-103: Qhov no yog tus txheej txheem tseem ceeb tswj cov high-voltage load break keyboards. Nws muab cov lus qhia rau kev tsim, kev sim, thiab kev ua haujlwm ntawm cov hluav taws xob hluav taws xob siv hluav taws xob siv los rhuav tshem cov khoom tam sim no. Ib qho ntawm cov kev ntsuam xyuas tseem ceeb uas tau teev tseg hauv tus qauv no yog qhov kev sim "ua thiab rhuav tshem lub peev xwm", uas ua kom ntseeg tau tias qhov hloov pauv tuaj yeem tuav cov khoom thauj tam sim no yam tsis muaj hluav taws xob arcing lossis kev ua haujlwm tsis zoo.

2. IEEE C37.71: Hauv Tebchaws Meskas, tus qauv no tswj hwm qhov kev ntaus nqi thiab kev ua haujlwm ntawm cov hloov pauv hloov. Nws qhia txog cov txheej txheem kuaj, suav nrog kev ntsuas luv luv, ntsuas dielectric, thiab muaj peev xwm nqa tam sim no txuas ntxiv. Cov txheej txheem no ua kom ntseeg tau tias qhov hloov pauv tuaj yeem ua haujlwm tau zoo nyob rau hauv lub ntiaj teb tiag tiag, ua rau nws yog qhov tseem ceeb hauv North America.

Cov qauv no tseem ceeb heev vim tias lawv tsis tsuas yog ua kom muaj kev nyab xeeb ntawm cov cuab yeej siv tab sis kuj tseem tiv thaiv cov neeg ua haujlwm thiab cov pej xeem los ntawm kev tiv thaiv kev ua tsis tiav uas tuaj yeem ua rau muaj xwm txheej txaus ntshai.

Tiv tauj peb rau cov qauv dawb los sim cov qauv no hauv kev xyaum.

Yuav ua li cas Load Break Switches cuam tshuam hluav taws xob System kev ntseeg tau?

Kev ntseeg tau yog qhov tseem ceeb hauv cov tshuab hluav taws xob siab, thiab cov khoom siv hluav taws xob tawg ua lub luag haujlwm tseem ceeb hauv kev tswj nws. Thaum xav txog dab tsi ua rau kev hloov pauv hloov kev ntseeg siab, ib tus yuav tsum saib nws lub peev xwm los cais tawm thiab tiv thaiv qhov chaw ntawm cov khoom siv hluav taws xob yam tsis muaj kev cuam tshuam tsis tsim nyog.

Kev ua haujlwm siab ntawm kev hloov pauv, uas feem ntau txhais los ntawm IEC 62271-103, ua kom cov khoom siv tuaj yeem tiv taus ntau txhiab kev hloov pauv yam tsis muaj kev puas tsuaj. Kev siv arc-extinguishing nruab nrab, zoo li sulfur hexafluoride (SF6), kuj txhim khu kev ntseeg tau los ntawm kev txo qis hnav thiab tsim kua muag ntawm cov khoom siv hloov. Qhov no ua rau lawv muaj txiaj ntsig zoo hauv thaj chaw xws li daim phiaj hluav taws xob tauj dua tshiab, qhov uas yuav tsum tau hloov pauv ntau zaus.

Kev tso kawm thiab kev nkag mus tau ntawm kev hloov pauv hloov pauv hauv lub network kuj tseem ua rau muaj kev ntseeg tau ntawm tag nrho. Cov keyboards uas yooj yim rau kev saib xyuas thiab kev sim tuaj yeem muab kev pabcuam sai, txo qis sijhawm thaum kho lossis tshuaj xyuas.

Dab tsi yog Qhov Kev Xeem thiab Ntawv Pov Thawj Yuav Tsum Tau Ua Rau Load Break Switches?

Kev ntsuam xyuas thiab ntawv pov thawj yog qhov yuav tsum tau ua rau kev hloov pauv hloov kom ntseeg tau tias lawv ua tau raws li cov qauv tsim nyog thiab kev nyab xeeb. Raws li IEC thiab IEEE cov lus qhia, muaj ntau theem ntawm kev sim uas qhov kev hloov pauv hloov yuav tsum tau ua ntej tau ntawv pov thawj rau kev siv.

1. Hom Kev Xeem: Qhov no suav nrog cov kev sim nruj xws li kev sim dielectric lub zog, ua thiab kev ntsuas qhov muaj peev xwm tawg, thiab ntsuas kub nce. Cov kev ntsuam xyuas no yog tsim los simulate cov xwm txheej hauv ntiaj teb tiag tiag qhov kev hloov pauv tuaj yeem ntsib thaum nws lub neej ua haujlwm.

2. Kev sim niaj hnub: Thaum qhov hloov pauv dhau qhov kev sim, cov kev ntsuam xyuas niaj hnub tau ua ntawm txhua qhov kev hloov khoom siv los xyuas kom meej qhov zoo ib yam ntawm cov khoom tsim khoom. Cov kev ntsuam xyuas no feem ntau suav nrog kev sim ua haujlwm ua haujlwm thiab kev ntsuas kev tiv thaiv hluav taws xob.

3. Kev Xeem EnduranceIEC 62271-103 qhia txog kev sim siab los txiav txim seb muaj pes tsawg qhov kev hloov pauv hloov pauv tuaj yeem ua haujlwm ua ntej nws qhia pom tias tsis ua haujlwm lossis txo kev ua haujlwm. Qhov kev ntsuam xyuas no yog qhov tseem ceeb tshwj xeeb rau cov keyboards siv hauv kev lag luam nrog kev ua haujlwm nquag.

Daim ntawv pov thawj los ntawm lub cev lees paub xws li KEMA lossis UL ntxiv kom paub tseeb tias qhov hloov pauv hloov ua raws li txhua yam kev xav tau kev nyab xeeb thiab kev ua haujlwm. Yog tias tsis muaj ntawv pov thawj kom raug, qhov hloov pauv hloov pauv yuav tsis raug cai siv tau hauv qee thaj tsam lossis kev lag luam.

Yog xav paub ntxiv txog cov txheej txheem xeem thiab ntawv pov thawj, tiv tauj peb rau cov qauv dawb, thiab peb tuaj yeem muab cov ntaub ntawv ntxaws ntxaws.

Yuav ua li cas Environmental Conditions cuam tshuam rau Load Break Switch Performance?

Ib puag ncig yam xws li qhov kub thiab txias, av noo, thiab qhov siab tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov hloov pauv hloov. Piv txwv li, cov keyboards ua haujlwm ntawm qhov siab siab tuaj yeem ua rau muaj qhov txo qis hauv lawv lub zog dielectric vim yog huab cua nyias, uas tuaj yeem txo cov peev txheej insulating tag nrho ntawm qhov hloov. IEC 62271-1 muab cov lus qhia yuav ua li cas kho cov khoom siv ntsuas thaum siv nyob rau hauv ib puag ncig uas muaj huab cua phem.

Nyob rau hauv cov cheeb tsam uas muaj av noo siab los yog corrosive ib puag ncig, ntxiv tiv thaiv txheej thiab cov ntaub ntawv tej zaum yuav tsim nyog los tiv thaiv cov deterioration ntawm cov khoom tseem ceeb. Kev saib xyuas kom raug thiab kev tshuaj xyuas tsis tu ncua kuj tseem yog qhov tseem ceeb los xyuas kom meej tias ib puag ncig yam tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm cov hloov pauv hloov.
