Kev Taw Qhia Rau Chav Tsev Tseem Ceeb ntawm Lub Nplhaib

Lub txee network nplhaib feem ntau hu ua SF6 load switch thiab SF6 load switch + fuse combination appliance siv rau hauv kab network nplhaib lossis lub davhlau ya nyob twg. SF6 load switch yog lub load switch zoo heev uas ntau tus neeg siv tau ntsib hauv xyoo tas los no. Ntxiv rau qhov zoo ntawm lub neej hluav taws xob ntev, lub zog tawg muaj zog thiab lub tshuab nqus tsev load switch, nws cov txiaj ntsig zoo tshaj plaws yog yooj yim ua tiav peb txoj haujlwm ua haujlwm (rau, tawm thiab hauv av), tam sim no me me (inductance, capacitance) kom qhib thiab tawg, thiab muaj peev xwm tiv taus cov xwm txheej ib puag ncig hnyav. Nws yog qhov tsim nyog rau kev nrov npe thiab siv rau hauv nroog thiab thaj chaw deb nroog nruab nrab voltage faib network.

Lub txee network nplhaib feem ntau muab faib ua ob hom: cua rwb thaiv tsev thiab SF6 rwb thaiv tsev. Nws yog siv rau kev faib thiab kaw cov khoom thauj tam sim no, qhib thiab rhuav cov khoom thauj tam sim no luv luv thiab cov khoom thauj tam sim no tsis muaj transformer, thiab them tam sim no ntawm cov kab saum toj kawg nkaus thiab cov kab cable ntawm qhov deb. Nws ua lub luag haujlwm tswj thiab tiv thaiv, thiab yog ib qho khoom siv hloov pauv tseem ceeb rau lub nplhaib network fais fab mov thiab lub zog fais fab kawg. Hauv lub cev txee, lub qhov hloov thauj khoom uas muaj cua rwb thaiv tsev feem ntau suav nrog hom tsim roj, hom siab thiab hom nqus tsev. Lub qhov hloov thauj khoom uas muaj SF6 rwb thaiv tsev yog hom SF6. Vim tias SF6 roj raug kaw hauv lub plhaub, qhov tawg ntawm nws tsim tsis pom. Lub qhov hloov thauj khoom hauv lub txee network nplhaib feem ntau xav tau peb qhov chaw nres tsheb, uas yog, txiav cov khoom thauj, cais lub voj voog, ua tau los ntawm kev sib txuas. Hom tsim roj, hom siab thiab SF6 hom thauj khoom hloov yooj yim ua tiav peb qhov chaw nres tsheb, thiab lub tshuab tua hluav taws xob arc tsuas yog tawg tau, tsis tuaj yeem cais tawm, yog li feem ntau lub qhov hloov thauj khoom nplhaib nqus tsev ua ntej lub qhov hloov thauj khoom ntxiv lub qhov hloov cais tawm, txhawm rau tsim kom muaj kev tawg cais tawm.

Lub qhov hloov pauv thauj khoom yog ib hom khoom siv hloov pauv uas muaj lub cuab yeej tua hluav taws xob yooj yim. Lub qhov hloov pauv thauj khoom uas siv roj SF6 ua cov khoom rwb thaiv tsev thiab cov khoom tua hluav taws xob hu ua SF6 qhov hloov pauv thauj khoom. Nws tuaj yeem siv los qhib thiab kaw qhov tam sim no thauj khoom thiab qhov tam sim no overload, thiab tseem tuaj yeem siv los qhib thiab kaw cov kab tsis muaj thauj khoom, cov transformers tsis muaj thauj khoom thiab cov txhab nyiaj capacitor, thiab lwm yam. Lub qhov hloov pauv thauj khoom peb-ntsis nrog cov haujlwm ntawm qhib, kaw thiab av muaj cov yam ntxwv ntawm cov qauv yooj yim thiab tus nqi pheej yig. Tsuas yog lub qhov hloov pauv thauj khoom thiaj li tsis tuaj yeem txiav qhov tam sim no luv luv.

SF6 load switch + fuse combination appliance yog los ntawm SF6 load switch kom dais overload current (qhov overload current rau SF6 load switch tseem nyob hauv qhov ntau ntawm load switch rated off current) thiab ua haujlwm tam sim no kaw thiab tawg, thiab kuj yuav tsum dais "hloov current" tawm. Cov high voltage fuses yog lub luag haujlwm rau kev tiv thaiv luv luv thiab overload tiv thaiv ntawm sab high voltage. Lub sijhawm no, ib pawg ntawm SF6 load switch thiab peb fuses nrog triggers, tsuav yog muaj kev ua trigger, nws cov mechanism txuas yuav ua rau load switch peb-theem automatic switch. Kev sib xyaw ua ke ntawm ob qho no tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev tiv thaiv kev ua haujlwm ntawm lub zog faib hluav taws xob hauv qab qhov xwm txheej ib txwm thiab qhov txhaum.

Lub txee network nplhaib tuaj yeem muab faib ua lub network nplhaib sab hauv tsev thiab lub network nplhaib sab nraum zoov

Lub network sab hauv tsev feem ntau yog siv rau kev faib hluav taws xob ntawm sab high voltage. Nws yog tsim los ntawm cov kab nkag, lub txee ntsuas, lub txee PT thiab lub txee hluav taws xob. Rau cov neeg siv uas muaj kev xav tau hluav taws xob siab, cov kab nkag yuav tsum tau txais lub txee hloov hluav taws xob ob chav. Lub plag tsev xya hais tias "tam sim no qee tus neeg yuav thauj khoom hloov thiab fuse ua ke ntawm lub txee hloov hluav taws xob siab hu ua lub nplhaib network txee, feem ntau yooj yim kom paub qhov txawv nrog lub txee hloov hluav taws xob" tsis yog qhov tseeb, lub nplhaib network txee kuj muaj qhov kev pab cuam Circuit Breaker.

Feem ntau siv rau hauv nroog fais fab network, siv hom SF6 ring network txee, qhov tseem ceeb tshaj plaws ntawm hom txee no yog qib kev tiv thaiv siab, ua tau IP67, haum rau sab nraum zoov, thiab tuaj yeem tsau rau hauv dej rau lub sijhawm luv luv. Lub voj voog fais fab network feem ntau siv ib lub voj voog rau hauv, ib lub voj voog tawm, ob lossis peb zaug ua lub voj voog tawm, uas yog, kev tsim ntawm tes hauv tes voj voog network fais fab hom.

Yuav kom ntseeg tau tias qhov kev ntseeg tau thiab kev sib txuas ntawm lub zog fais fab, ob txoj kab nkag tau siv los muab hluav taws xob, uas tsim ib lub nplhaib. SF6 load switch, 3 chaw nres tsheb (kaw, qhib, av), kab ceg, transformer.
