Xaiv qhov nruab nrab -voltage nqus Circuit Court breaker yog ib qho tseem ceeb tshaj plaws ntawm tag nrho cov hluav taws xob faib hluav taws xob tsim qauv.
Kev xaiv raug ua kom muaj kev nyab xeeb thiab kev ntseeg tau; kev xaiv tsis raug tuaj yeem ua rau muaj kev phom sij loj.
Cov hauv qab no qhia txog cov ntsiab lus tseem ceeb xaiv los ntawm rau qhov loj me.
I. Basic Parameters: Voltage thiab tam sim no
Thawj kauj ruam hauv kev xaiv yog kom paub meej tias puas tuaj yeem siv lub tshuab hluav taws xob hauv qhov system.
Qhov ntsuas hluav taws xob yuav tsum siab tshaj qhov kev ua haujlwm siab tshaj plaws-12kV rau 10kV system, 24kV rau 20kV system, thiab 40.5kV rau 35kV system.
Qhov no yog daim ntawv pov thawj kev nyab xeeb uas tau teev tseg los ntawm cov qauv hauv tebchaws; qhov system voltage tsis tuaj yeem kho raws li cov khoom siv hluav taws xob.
Qhov ntsuas tam sim no yuav tsum muaj ntau dua li qhov siab tshaj plaws ntawm kev ua haujlwm txuas ntxiv tam sim no, thaum tseem xav txog qhov ntev - lub sij hawm thauj khoom loj hlob. Cov kev ntsuas tam sim no suav nrog 630A, 1250A, 1600A, 2000A, 2500A, 3150A, thiab 4000A. Piv txwv li, 2000kVA transformer muaj qhov ntsuas tam sim no ntawm kwv yees li 115A ntawm 10kV sab.
Txawm li cas los xij, xav txog lub nplhaib tes hauj lwm thiab overload, qhov kev ntsuam xyuas 630A feem ntau yog xaiv. Yog xav tau kev nthuav dav ntxiv rau yav tom ntej, qhov ntsuas 1250A tuaj yeem xaiv ncaj qha.
II. Core Capability: Breaking Current
Qhov no yog qhov tseem ceeb tshaj plaws kev ua tau zoo ntawm lub Circuit Court breaker, txiav txim siab nws lub peev xwm los tiv thaiv luv luv Circuit Court.
Qhov ntsuas luv luv-circuit breaking tam sim no yuav tsum ntau dua lossis sib npaug rau qhov siab tshaj plaws uas xav tau luv luv-circuit tam sim no ntawm qhov chaw teeb tsa. Kev ntsuam xyuas feem ntau yog 20kA, 25kA, 31.5kA, 40kA, thiab 50kA.
Rau cov chaw nres tsheb hauv nroog nrog luv luv - Circuit Court muaj peev xwm, qhov ntsuas ntawm 31.5kA lossis siab dua yog pom zoo; rau lub davhlau ya nyob twg faib circuits, 25kA feem ntau yog txaus.
Lwm qhov yooj yim saib tsis tau yog qhov ntsuas luv luv -circuit ua tam sim no (nce tus nqi), uas feem ntau yog 2.5 npaug ntawm qhov tam sim no tawg.
Nws ntsuas lub zog ntawm lub tshuab hluav taws xob hluav taws xob thaum nws ntsib lub voj voog luv luv thaum kaw - yog tias qhov ntsuas no tsis txaus, lub Circuit Court breaker yuav tawg thaum lub sijhawm kaw.
III. Environmental Adaptability
Qhov chaw nyob rau hauv uas lub Circuit Court breaker raug ntsia ncaj qha cuam tshuam nws lub neej kev pab cuam.
Cov khoom lag luam tsim nyog rau qhov siab tshaj 1000 meters. Saum toj no qhov siab, huab cua yog nyias, rwb thaiv tsev lub zog txo, yuav tsum tau derating los yog xaiv hom "siab-altitude".
Cov chaw muaj kuab paug kuj tseem ceeb heev- hauv cov nroj tsuag tshuaj, thaj chaw ntug dej hiav txwv, thiab cov chaw muaj plua plav, cov insulators zoo ib yam yuav ua rau muaj kev nkag siab thiab flashover. Hauv cov xwm txheej zoo li no, nws raug nquahu kom xaiv cov khoom- insulated ncej hom, qhov twg cov arc- tua chamber yog tag nrho cam khwb cia rau hauv epoxy resin, muab kev tiv thaiv kev ua qias tuaj, noo noo, thiab corrosion, ua rau nws muaj kev ntseeg siab ntau dua li cov tsoos insulated cylinder hom.
Tsis tas li ntawd, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm kev teeb tsa sab hauv tsev thiab sab nraum zoov: hom sab hauv tsev ntsia hauv switchgear tsuas yog yuav tsum muaj qhov ntsuas IP4X tiv thaiv; sab nraum zoov ncej- hom mounted yuav tsum siv ncej-mounted lub tshuab nqus tsev Circuit Court breakers nrog hlau casings, IP54 los yog siab dua tiv thaiv ntsuas, thiab muaj peev xwm tiv taus tshav ntuj thiab los nag.
IV. Mechanical yam ntxwv thiab kev khiav hauj lwm Mechanism
Qhov no txiav txim siab seb lub Circuit Court breaker tuaj yeem ua haujlwm tau zoo. Mechanical lifespan yog qhov taw qhia tseem ceeb.
Thaum 10,000 lub voj voog txaus rau kev faib hluav taws xob zoo tib yam, nyob rau hauv ib puag ncig zoo li steel mills thiab dov mills qhov chaw ua haujlwm tau rov ua dua kaum ob zaug hauv ib hnub, cov hluav taws xob zoo tib yam tuaj yeem hnav tawm hauv ob peb xyoos xwb.
Hom kev ua haujlwm nquag nrog lub tshuab ua haujlwm ntawm 30,000 cycles lossis ntau dua yuav tsum raug xaiv.
Hom kev khiav hauj lwm mechanism kuj tseem ceeb: lub caij nplooj ntoos hlav mechanisms yog qhov feem ntau, tso cai rau kev tuav haujlwm txawm tias thaum lub sij hawm fais fab tuag, thiab kuj muaj nqis; Cov cuab yeej hlau nplaum ruaj khov yog qhov yooj yim hauv cov qauv, kev saib xyuas -dawb, thiab muaj lub neej ntev, haum rau kev ua haujlwm nquag, tab sis kev ua haujlwm ntawm phau ntawv yog cumbersome thaum fais fab tuag.
Kev tswj qhov hluav taws xob yuav tsum sib haum rau qhov kev tswj hwm. Feem ntau siv voltages yog DC110V, DC220V, thiab AC220V.
Qhov no yuav tsum tau teev tseg thaum xaj, txwv tsis pub, lub Circuit Court breaker yuav tsis kaw ntawm -site.
V. Sib txuam nrog Switchgear Circuit Breakers
Lub tshuab nqus tsev Circuit Court breakers tsis cais; lawv yuav tsum tau nruab rau hauv switchgear, thiab qhov ntev thiab interfaces yuav tsum haum txig.
Ua ntej, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm cov tsheb thauj khoom-mounted thiab tsau hom-KYN28 nruab nrab-voltage switchgear tsuas yog tuaj yeem ua ke nrog tsheb thauj khoom-mounted Circuit Court breakers, xws li VS1-12; XGN lossis HXGN taag switchgear yog ua ke nrog cov khoom siv hluav taws xob ruaj khov.
Retrofitting qub Circuit Court breakers yog qhov nyuaj dua, yuav tsum tau ua pov thawj ntawm theem - mus rau -theem deb, mounting qhov sib nrug, thiab qhov ntev ntawm lub thawv.
Qhov zoo tshaj plaws, cov duab ntawm lub xaib yuav tsum tau muab coj los xyuas seb peb cov khoom puas tuaj yeem hloov pauv ncaj qha.
Muaj ntau qhov project retrofit yuav tsum tau rov ua haujlwm dua vim qhov tsis sib haum xeeb.
VI. Daim Ntawv Thov Tshwj Xeeb Scenarios
Cov kev lag luam sib txawv muaj cov kev xav tau ntxiv rau cov hluav taws xob hluav taws xob.
Qhov luv luv -circuit tam sim no ntawm lub tshuab hluav taws xob qhov hluav taws xob qeeb qeeb thiab muaj cov khoom siv DC siab;
Cov hluav taws xob hluav taws xob zoo tib yam yuav tsis tuaj yeem qhib nws, yuav tsum muaj lub tshuab hluav taws xob tshwj xeeb hluav taws xob hluav taws xob hluav taws xob.
Hloov cov tsev txhab nyiaj capacitor yuav tsum cuam tshuam cov peev txheej tam sim no, tsim nyog xaiv cov khoom siv C2-chav kawm (capacitive breaking peev) cov khoom; txwv tsis pub, kev kav thiab overvoltage yog qhov zoo.
High- thaj tsam qhov siab thiab qhov txias txias kuj yuav tsum muaj kev tuav tshwj xeeb- siab- thaj chaw siab yuav tsum tau siab - kub hom hluav taws xob Circuit Court breakers nrog kev txhim kho rwb thaiv tsev theem; nyob rau sab qaum teb lub caij ntuj no nrog kub poob mus rau -30 lossis -40 degrees Celsius, cov cua sov yuav tsum muaj nyob rau hauv cov txheej txheem los tiv thaiv kom khov.
Cov ntsiab lus no yooj yim saib tsis tau hauv kev xaiv dav dav, tab sis lawv yog qhov tseeb ntawm cov cheeb tsam feem ntau ua rau tsis ua tiav tom qab.
