Nkag siab Siab thiab Tsawg Voltage Switchgear hauv 1 feeb: Cov txheej txheem ua tiav los ntawm kev hloov pauv hluav taws xob mus rau kev tiv thaiv txhaum

Hauv lub zog hluav taws xob, qhov hluav taws xob siab thiab tsis tshua muaj hluav taws xob hloov hluav taws xob yog cov khoom siv tseem ceeb los xyuas kom muaj kev nyab xeeb hluav taws xob. Nws zoo li tus thawj coj ntawm hluav taws xob, lub luag haujlwm rau kev nyab xeeb tig siab -voltage mus rau qis-voltage thiab ceev ceev tiv thaiv tag nrho cov kab sib chaws yog tias ib qho hluav taws xob tsis raug. Niaj hnub no peb yuav coj koj mus rau kev nkag siab zoo ntawm cov khoom siv tseem ceeb no cuam tshuam txog kev nyab xeeb.

01. Fais fab xa thiab hloov dua siab tshiab

High thiab low voltage switchgear yog ib qho chaw tswj kev sib koom ua ke ntawm lub zog hluav taws xob, feem ntau yog nruab rau hauv chav faib khoom lossis substation. Nws yog encapsulated hauv lub txee hlau thiab nws txoj haujlwm tseem ceeb yog kom tau txais, faib, tswj thiab tiv thaiv hluav taws xob hluav taws xob.

Nws tsis yog ib qho khoom siv nkaus xwb, tab sis muaj kev tswj hwm lub zog ua tiav, suav nrog siab -voltage switchgear, transformers, low-voltage switchgear thiab txuas tsheb npav, thiab lwm yam, ua haujlwm ua ke kom muaj kev nyab xeeb ntawm kev xa hluav taws xob.

Thaum lub siab -voltage hluav taws xob (feem ntau ntau dua 10kV) mus txog tus neeg siv, nws thawj zaug dhau los ntawm qhov siab -voltage switchgear kom tswj tau qhov tam sim no. Lub transformer ces hloov cov high voltage mus rau 380V / 220V qis-voltage hluav taws xob tsim nyog rau kev siv txhua hnub.

Thaum kawg, qhov qis -voltage switchgear raug xa mus rau qhov ua tiav qis -voltage hluav taws xob mus rau txhua lub chaw nres nkoj fais fab kom ntseeg tau tias txhua lub qhov (socket) thiab txhua lub cuab yeej tuaj yeem tau txais lub zog ruaj khov thiab nyab xeeb.

02. Kev nyab xeeb thiab kev ruaj ntseg mechanism

Lub siab thiab qis voltage switchgear kuj muaj kev ua haujlwm ntawm kev tiv thaiv txhaum. Thaum lub zog hluav taws xob ntsib cov xwm txheej txaus ntshai xws li overload, luv luv Circuit Court, thiab voltage abnormality, nws tuaj yeem teb tsis pub dhau milliseconds:

Thaum lub Circuit Court load tshaj qhov kev nyab xeeb, lub Circuit Court breaker yuav tam sim ntawd mus, txiav tawm lub hwj chim mov thiab tiv thaiv cov hlau los ntawm overheating thiab ua rau hluav taws; Nyob rau hauv qhov tshwm sim ntawm ib qho luv luv - Circuit Court txhaum, cov cuab yeej tiv thaiv hauv lub cuab yeej tuaj yeem paub qhov tsis xws luag thiab cais thaj chaw txhaum hauv 0.1 vib nas this. Thaum qhov hluav taws xob hloov pauv txawv txav, lub overvoltage thiab undervoltage tiv thaiv mechanism yuav qhib kom tiv thaiv cov cuab yeej precision los ntawm lub zog surges.

Cov kev tiv thaiv no tsis yog kev hloov pauv yooj yim, tab sis saib xyuas tam sim no, qhov hluav taws xob, qhov kub thiab txias thiab lwm yam tsis zoo los ntawm cov cuab yeej ntse ntse, thiab koom tes nrog microprocessors rau kev txiav txim siab ntse kom paub meej cov lus teb ntawm lub sijhawm tseem ceeb.

03. Cov ntsiab lus tseem ceeb rau kev xaiv cov xwm txheej sib txawv

Cov chaw sib txawv muaj qhov tshwj xeeb uas yuav tsum muaj rau siab thiab qis voltage switchgear. Nyob rau hauv lub Hoobkas Rhiav, cov cuab yeej yuav tsum tau tiv nrog qhov chaw ua hauj lwm ntawm high tam sim no thiab nquag pib thiab nres, thiab GCS hom rub- tawm switchgear tuaj yeem muaj peev xwm rau cov haujlwm xws li reactor tam sim no limiting thiab centralized motor tswj.

Hauv cov tsev lag luam, cov cuab yeej siv yuav tsum muaj kev tswj xyuas kev txawj ntse los txhawb kev saib xyuas tej thaj chaw deb thiab kev tsom xam siv hluav taws xob; Nyob rau hauv cov ntaub ntawv chaw, kev ntseeg siab thiab redundancy tsim yog qhov tseem ceeb tshaj plaws.

04. Kev Qhia Txog Kev Yuav Khoom: Nrhiav cov cuab yeej tsim nyog tshaj plaws hauv peb kauj ruam

1. Saib ntawm qhov tsis sib xws: Raws li lub zog thauj khoom thiab cov yam ntxwv ntawm qhov chaw, xaiv cov khoom siv nrog cov ntsuas hluav taws xob tsim nyog, tam sim no thiab muaj peev xwm tawg. Piv txwv li, qhov qis -voltage system nyob rau hauv ib qho chaw ua lag luam dav dav xaiv qhov ntsuas hluav taws xob ntawm 660V, thaum lub siab -voltage system yuav tsum xav txog qhov tshwj xeeb ntawm 10kV lossis siab dua.

2. Ua tib zoo saib xyuas cov ntawv pov thawj kev nyab xeeb: xyuas kom meej tias cov khoom siv tau dhau lub teb chaws yuav tsum tau ntawv pov thawj thiab cov qauv kev lag luam, thiab qib kev tiv thaiv ua tau raws li qhov yuav tsum tau ua ntawm kev teeb tsa ib puag ncig.

3. Hais Txog Kev Kho Kom Yooj Yim: Ua ntej cov khoom lag luam nrog cov qauv tsim qauv, tso cai rau kev saib xyuas lossis hloov pauv yam tsis muaj kev cuam tshuam rau tag nrho cov kev ua haujlwm, txo qis sijhawm.
