Yog vim li cas vim li cas lub tshuab nqus tsev vacuum tuaj yeem ua tiav ob qho "me me" thiab "ntev kev pab cuam lub neej" yog nyob rau hauv qhov ua tau zoo ntawm nws cov ntsiab lus tseem ceeb - lub tshuab nqus tsev cuam tshuam. Cia peb piav qhia qhov no kom ntxaws los ntawm ntau lub hauv paus ntsiab lus tseem ceeb:
Vim li cas lub ntim me me? (Compact qauv)
Qhov "me me" ntawm lub tshuab nqus tsev Circuit Court breaker feem ntau tshwm sim los ntawm qhov tsis tshua muaj hluav taws xob muaj zog ntawm lub tshuab nqus tsev ua ib qho nruab nrab insulating.
1. Lub tshuab nqus tsev yog ib qho zoo heev insulator: Raws li tus qauv atmospheric siab, huab cua molecules yog ntom, thiab cov khoom siv hluav taws xob (electrons, ions) tuaj yeem sib tsoo nrog cov roj molecules, tsim txoj hauv kev conductive (ie, ib qho arc). Hauv qhov chaw nqus tsev siab (feem ntau qis dua 10^-4 Pa), cov roj molecules tsis tshua muaj, thiab cov khoom siv hluav taws xob yuav luag tsis muaj lub hom phiaj sib tsoo, ua rau nws nyuaj rau kev tsim txoj hauv kev. Qhov no txhais tau hais tias lub zog rwb thaiv tsev ntawm lub tshuab nqus tsev vacuum yog ntau dua li qhov sib nrug ntawm huab cua, roj, lossis SF6 roj.
Kev pom kev sib piv: Qhov sib txawv ntawm 1-millimeter nqus tsev vacuum muaj qhov sib txawv ntawm qhov hluav taws xob ntau dua li 1-millimeter huab cua sib txawv. Yog li ntawd, txhawm rau tiv thaiv tib lub zog, qhov sib txawv ntawm qhov yuav tsum tau ua rau lub tshuab nqus tsev cuam tshuam tuaj yeem ua luv luv (feem ntau tsuas yog ob peb millimeters mus rau kaum millimeters).
2. Cov qauv yog compact heev: Vim yog qhov sib txawv me me, tag nrho cov cuam tshuam tuaj yeem ua rau me me. Hauv qhov sib piv:
1) Roj- cov khoom siv hluav taws xob puv: Yuav tsum muaj cov roj insulating ntau thiab cov qauv roj tank complex.
2) SF6 Circuit Court breakers: Yuav tsum muaj cov pa roj txaus thiab cov roj chamber qhov chaw kom muaj peev xwm tiv thaiv kev rwb thaiv tsev thiab arc extinguishing.
3) Cua Circuit Court breakers: Yuav tsum tau ib txoj kev ntev arc thiab arc ntes daim hlau.
Yog li ntawd, cov tub ntxhais interrupter chav tsev ntawm lub tshuab nqus tsev vacuum breaker nws tus kheej yog heev compact, nteg lub hauv paus rau lub miniaturization thiab txawj ntse ntawm tag nrho cov hloov txee (xws li roj- cov khoom ntim, cov khoom siv rwb thaiv tsev).
Vim li cas lub neej ua haujlwm ntev? (High ntseeg tau thiab durability)
"Long kev pab cuam lub neej" feem ntau tshwm sim nyob rau hauv ob yam: hluav taws xob lub neej (tus naj npawb ntawm qhib cycles) thiab txhua yam lub neej (tus naj npawb ntawm kev khiav hauj lwm).
Lub zog arc tsis tshua muaj siab, thiab kev sib cuag yog me me (tus yuam sij rau lub neej hluav taws xob ntev).
1) Cov yam ntxwv ntawm lub tshuab nqus tsev arcs:
Thaum arcs arc nyob rau hauv lub tshuab nqus tsev ib puag ncig, lub arc tsis yog tswj los ntawm cov pa ionization, tab sis yog tsim los ntawm evaporation ntawm cov khoom tiv tauj rau hauv hlau vapor. Txij li thaum tsis muaj huab cua molecules los tswj thiab nthuav tawm lub arc hauv lub tshuab nqus tsev, lub tshuab nqus tsev arc yog nruj me ntsis rau qhov me me, ci ntsa iab ntawm qhov chaw tiv tauj (hu ua cathode chaw), uas muaj qhov kub thiab txias tab sis muaj nyob rau lub sijhawm luv luv (microsecond level) thiab taug kev sai heev ntawm qhov chaw sib cuag.
2) Lub zog nruab nrab rov qab muaj zog:
3) Thaum qhov hloov pauv tam sim no dhau los ntawm xoom, lub arc yog tam sim ntawd tua, thiab cov hlau vapor kis tau sai heev hauv qhov chaw nqus thiab condenses sai, re- tso rau ntawm qhov chaw tiv thaiv thiab cov ntaub thaiv npog. Qhov no ua rau lub zog rwb thaiv tsev (lub zog rov qab nruab nrab) ntawm lub tshuab nqus tsev kom rov qab tau sai heev, tiv thaiv arc re- ignition.
4) Qhov tshwm sim: Vim lub zog arc qis thiab lub sijhawm luv luv (feem ntau tsuas yog ib nrab ntawm lub voj voog), txhua lub voj voog qhib muaj hluav taws xob tsawg heev ntawm kev sib cuag. Lub siab- lub tshuab nqus tsev nqus hluav taws xob tau yooj yim tuaj yeem ua tiav ntau txhiab lossis txawm tias 100,000 lossis ntau dua - lub peev xwm qhib, thaum cov neeg sib cuag ntawm cov tsoos hluav taws xob hluav taws xob yuav raug hlawv hnyav thiab yuav tsum tau hloov tom qab ob peb qhov qhib tam sim no.
5) Cov qauv kaw, kev saib xyuas -dawb (tus neeg kho tshuab lub neej thiab kev ruaj ntseg)
A. Kev cais tawm ntawm ib puag ncig sab nraud: Lub tshuab nqus tsev cuam tshuam yog lub kaw "black box". Cov kev sib cuag ua haujlwm hauv qhov chaw nqus tsev ntshiab, tsis muaj kev cuam tshuam los ntawm lwm yam xws li av noo, plua plav, tshuaj corrosion, thiab qhov siab. Qhov no hauv paus tshem tawm cov kev ua txhaum uas tshwm sim los ntawm deterioration ntawm cov rwb thaiv tsev sab nraud.
B. Kev khiav hauj lwm yooj yim: Vim qhov sib txawv me me, lub zog ua haujlwm yuav tsum yog me me, thiab lub tshuab ua haujlwm (xws li lub caij nplooj ntoos hlav mechanism) tuaj yeem tsim kom sib zog thiab txhim khu kev qha. Qhov no feem ntau tso cai rau nws lub neej txhua yam kom ncav cuag kaum tawm txhiab.
C. Cov ntaub ntawv tshwj xeeb
Lub tshuab nqus tsev vacuum breaker siv tshwj xeeb tsim tooj liab -chromium (CuCr) thiab lwm yam ntaub ntawv sib xyaw ua ke. Cov ntaub ntawv no muaj cov yam ntxwv hauv qab no:
Muaj peev xwm tawg: Muaj peev xwm cuam tshuam cov dej ntws loj.
High conductivity: Txo cov cua sov tsim thaum lub sijhawm ua haujlwm ib txwm muaj.
Tsawg tus nqi mus txawv tebchaws: Txo kev ua haujlwm overvoltage thiab tiv thaiv cov khoom siv.
Resistant rau arc yaig: Ntxiv mus kom hluav taws xob lifespan.
Nyob rau hauv cov ntsiab lus, los ntawm leveraging lub cim nruab nrab ntawm "lub tshuab nqus tsev", lub nqus Circuit Court breaker zoo kawg nkaus sib npaug qhov tsis sib haum xeeb xav tau ntawm "miniaturization" thiab "ntev lifespan" uas feem ntau contradictory nyob rau hauv ib txwm technologies. Yog li ntawd, nws tau dhau los ua cov kev daws teeb meem tseem ceeb hauv qhov nruab nrab -voltage field (tshwj xeeb yog nyob rau hauv thaj tsam ntawm 12kV - 40.5kV).
kub muag khoom
VTZ-12 sab hauv tsev theem-xaiv hloov ntse lub tshuab nqus tsev Circuit Court breaker(Tongzhong Electric tus qauv tshwj xeeb) yog tsim rau sab hauv tsev switchgear nrog lub ntsuas hluav taws xob ntawm 12kV thiab AC 50/60Hz. Nws siv cov hlau nplaum ua haujlwm ruaj khov thiab tsim nyog rau cov ntawv thov tshwj xeeb hauv ntau lub tuam txhab kev lag luam thiab mining thiab cov phiaj xwm hluav taws xob. Chav tsev trolley tuaj yeem siv ncaj qha nrog lubKYN28A-12 switchgear,ncaj qha hloov cov papeb -theem integrated nqus Circuit Court breakershauv switchgear uas twb muaj lawm.
Qhov no ntse lub tshuab nqus tsev Circuit Court breaker nta aruaj khov hlau nplaum mechanism, ib tug ruaj khov hlau nplaum mechanism maub los, thiab ib tug ntse processor. Peb tswj, ua haujlwm nrogpeb ywj siab mus tas li hlau nplaum mechanisms, pab kom theem- xaiv hloov ntawm peb- theem tshuab. Tsis tas li ntawd, cov khoom siv ntse ntse nta kev ua haujlwm tau zoo, siv cov lus tawm tswv yim los ntawm qhov hluav taws xob thiab cov teeb liab tam sim no rau kev suav nrog synchronous thiab tshaj tawm cov lus txib kom ua rau lub Circuit Court breaker hloov mus rau thiab tawm ntawm txhua theem, ua tau raws li ntau hom kev thov.
