Yuav kom nkag siab txog "lub tshuab nqus tsev vacuum breaker haum rau kev sib cais", peb tuaj yeem rhuav tshem nws mus rau hauv ob qhov kev nkag siab thiab tom qab ntawd sib xyaw ua ke.
Part 1: Nqus Circuit Court Breaker (VCB)
Lub tshuab nqus tsev Circuit Court breaker yog cov cuab yeej tseem ceeb rau kev txiav thiab kev tiv thaiv.
Lub hauv paus ntsiab lus: Nws qhov arc- tua hluav taws thiab insulating nruab nrab yog lub tshuab nqus tsev siab (siab tshaj 10^-4 Pa). Thaum cov kev sib cuag sib cais thiab ib qho arc tsim, lub tshuab nqus tsev ib puag ncig ua rau lub arc tua sai heev ntawm thawj xoom hla ntawm tam sim no, vim tias yuav luag tsis muaj qhov nruab nrab ionizable hauv lub tshuab nqus tsev kom txhawb nqa lub arc.
Core Function: Nws txuas thiab nqa ib txwm tam sim no, thiab sai thiab ntseeg tau tshem tawm qhov txhaum tam sim no thaum muaj kev txhaum (xws li luv luv Circuit Court). Nws ua zoo li lub zog loj thiab teb "kev nyab xeeb hloov", tiv thaiv cov kab hauv qab thiab cov khoom siv los ntawm kev puas tsuaj.
Ntu 2: Kev cais tawm muaj nuj nqi
"Kev cais tawm" ntawm no yog ib lo lus tshwj xeeb ntawm kev nyab xeeb hluav taws xob, xa mus rau kev tsim kom muaj kev ntseeg siab thiab pom kev cuam tshuam los xyuas kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv.
Kev ruaj ntseg cov cai: Raws li cov qauv kev nyab xeeb hluav taws xob (xws li IEC 62271-102), tsuas yog txiav tawm lub voj voog tsis txaus. Yuav tsum muaj qhov pom qhov sib txawv ntawm huab cua nrog qhov kev nyab xeeb txaus los ua pov thawj tias lub voj voog tau raug cais tawm ntawm lub hwj chim sab nraud. Tsuas yog nyob rau hauv txoj kev no tuaj yeem saib xyuas cov neeg ua haujlwm kom paub tseeb tias tsis muaj kev pheej hmoo ntawm hluav taws xob poob siab thiab ua haujlwm kho kom zoo.
Kev coj ua ib txwm ua: yav dhau los, ib qho khoom siv ywj pheej - ib qho kev sib txuas - feem ntau yog txuas nrog hauv cov kab nce toj lossis hauv qab ntawm lub tshuab hluav taws xob. Lub disconnector tsis muaj arc -extinguishing muaj peev xwm thiab yuav tsis ua hauj lwm nyob rau hauv load. Nws tsuas yog siv los muab qhov pom kev tawg tom qab qhib lub Circuit Court breaker.
Kev nkag siab zoo: "Nqus Circuit Court breaker haum rau kev sib cais"
Lub tswv yim no txhais tau hais tias lub tshuab nqus tsev vacuum Circuit Court breaker, ntxiv rau qhov muaj peev xwm txiav tawm tam sim no, nws cov qauv tsim thiab kev ua tau zoo kuj ua tau raws li cov qauv kev nyab xeeb ntawm disconnector thiab tuaj yeem ua lub luag haujlwm ntawm "kev cais tawm".
Qhov no feem ntau txhais tau tias nws muaj ib lossis ntau dua ntawm cov yam ntxwv tseem ceeb hauv qab no:
Pom pom kev sib cuag (pom pom kev sib cais): Qhov no yog qhov tseem ceeb tshaj plaws. Kev tsim qauv ntawm cov cuab yeej tso cai rau cov neeg ua haujlwm saib xyuas kom pom tseeb tias thaum lub tshuab hluav taws xob nyob rau hauv "qhib / kuaj / cais" txoj haujlwm, kev txav mus los thiab nyob ruaj khov tau sib cais los ua qhov sib txawv ntawm huab cua ntshiab thiab txaus txaus. Qhov kev sib txawv no yuav tsum ua kom tau raws li cov txheej txheem rwb thaiv tsev thiab kev nyab xeeb kev nyab xeeb uas tau teev tseg los ntawm cov qauv.
Txhim khu kev qha txoj hauj lwm qhia thiab xauv mechanism:
Nws muaj cov cim qhia meej meej rau "kaw", "qhib", thiab "cais tawm / kos tawm".
Mechanical interlocking yog muab los tiv thaiv kev ua haujlwm tsis zoo ntawm kev txav lub Circuit Court breaker mus rau qhov kev sib cais thaum nws raug kaw.
Nws raug tso cai rau nruab padlocks ntawm cov ntsiab lus sib cais los siv cov txheej txheem kev nyab xeeb "lockout/tagout" thiab tiv thaiv lwm tus los ntawm kev kaw qhov hloov pauv.
Ua tau raws li kev rwb thaiv tsev ntawm kev sib cais: Nyob rau hauv txoj haujlwm qhib, qhov sib txuas sib txuas thiab cov khoom siv insulating muaj peev xwm tiv taus lub zog zaus tiv taus qhov hluav taws xob thiab impulse tiv taus qhov ntsuas hluav taws xob tau teev tseg los ntawm tus qauv, kom ntseeg tau tias kev sib cais txhim khu kev qha txawm nyob rau hauv cov xwm txheej overvoltage.
Loop resistance stability: Lub voj tseem ceeb tseem nyob ruaj khov tom qab lub sijhawm ua haujlwm ntev -, kom ntseeg tau tias muaj cua sov ib txwm muaj thaum ua haujlwm raws li txoj hauv kev coj thiab txhim khu kev qha thaum ua haujlwm raws li kev sib cais.
Vim li cas thiaj tseem ceeb? Dab tsi yog qhov zoo?
Kev sib xyaw ua haujlwm ntawm Circuit Court breaker thiab disconnector feem ntau coj cov txiaj ntsig hauv qab no:
Txuag qhov chaw thiab tus nqi: Tsis tas yuav nruab ib lub tshuab hluav taws xob sib cais ntxiv lawm, tshwj xeeb tshaj yog tsim rau cov chaw uas muaj qhov txwv, xws li nruab nrab -voltage switchgear (KYN28A-12, thiab lwm yam).
Ua kom yooj yim rau kev khiav lag luam thiab txhim kho kev ntseeg tau: Kev ua haujlwm ua ntu zus yog yooj yim dua, txo cov kauj ruam rau kev khiav hauj lwm qhov kev hloov pauv thiab qhov ua tau ntawm tib neeg yuam kev. Mechanical interlock kuj tseem ncaj qha thiab txhim khu kev qha.
Txhim khu kev ruaj ntseg: Qhov kev sib cais qhov muag pom tau ncaj qha mus rau hauv Circuit Court breaker, ua kom pom kev nyab xeeb tam sim ntawd.
Summary thiab Analogy
Koj tuaj yeem nkag siab nws vividly li no:
Ordinary nqus Circuit Court breaker: Nws zoo li lub hwj chim tsis siv neeg Circuit Court breaker. Thaum nws mus txawv tebchaws, lub hwj chim hauv kab raug txiav tawm, tab sis koj tsis tuaj yeem paub tseeb tias nws tau txiav tag nrho sab hauv, thiab koj tsis txhob kov txoj kab nrog koj txhais tes liab qab vim tias nws tseem tuaj yeem ua neej nyob yog tias muaj kev txhaum.
Lub tshuab nqus tsev Circuit Court breaker haum rau kev sib cais: Nws zoo li lub tshuab hluav taws xob tsis siv neeg nrog "pom riam hloov". Thaum nws mus txawv tebchaws, nws tsis tsuas yog txiav tawm tam sim no tab sis kuj txuas ntxiv qhov tseeb, lub cev insulating riam hloov, tso cai rau koj pom ntawm koj tus kheej ob lub qhov muag tias lub voj voog sib cais tag nrho. Tsuas yog tom qab ntawd koj tuaj yeem ruaj ntseg dai "Ua haujlwm hauv kev ua tiav, tsis txhob kaw" kos npe thiab ua kom muaj kev nyab xeeb.
Yog li ntawd, thaum yuav los yog tsim lub tshuab hluav taws xob, tshwj xeeb tshaj yog ib qho uas yuav tsum tau kuaj xyuas thiab tu, "tsim nyog rau kev sib cais" yog qhov tseem ceeb ntawm kev nyab xeeb kev ua tau zoo, txhais tau hais tias qhov hluav taws xob hluav taws xob no tau tsim tshwj xeeb los ua kom cov neeg ua haujlwm nyab xeeb.
VTZ-12 nqus Circuit Court breaker
VTZ-12 nqus Circuit Court breaker(tshwj xeeb qauv ntawm Tongzhong Hluav taws xob Co., Ltd.) yog ib tug sab hauv tsev switchgear rau rated voltage 12kV, AC 50/60Hz. Nws siv lub tshuab ua haujlwm modular thiab tsim nyog rau ntau yam kev lag luam thiab kev lag luam mining, nrog rau cov khoom siv hluav taws xob. Nws tuaj yeem siv los ua ib lub tawb nqa khoom siv nrog KYN28A-12 switchgear, los yog raws li ib qho chaw ruaj khov nrog cov khoom siv sib cuam tshuam, ua rau nws haum rau XGN2 thiab lwm cov khoom ruaj khov.
