SF₆ Circuit Court breakers Workflow tawg
SF₆ tsis siv neeg cais cov keyboards siv lub siab dielectric zog ntawm cov roj los cuam tshuam qhov tam sim no.
Thaum cov kev sib cuag qhib, ib qho arc yog tsim, thiab qhov kub ntawm lub arc ua rau SF₆ molecules decompose rau hauv oxygen thiab fluorine atoms.Cov fluorine atoms sai ntes cov electrons sai, tsim hnyav tsis zoo ions txav maj mam, uas zoo heev txo cov conductivity ntawm qhov sib txawv.
Nyob rau tib lub sijhawm, lub breaker yog nruab nrog lub tshuab puffer lossis self-blast arc-blowing mechanism uas ua rau cov pa roj nrawm nrawm thaum lub sijhawm qhib kev ua haujlwm, yuam kom cheb tawm thiab ua kom txias cov khoom hauv lub arc. Qhov no tso cai rau lub zog dielectric hla qhov sib txawv kom rov qab tau sai ntawm qhov tam sim no ntawm xoom tam sim no, yog li ua tiav quenching arc.
Lub tshuab nqus tsev Circuit Court breakers Workflow breakdown
Tsis zoo li SF₆ breakers,Lub tshuab nqus tsev Circuit Court breakerstsis txhob cia siab rau "gas blowing" kiag li.
Lub siab nyob rau hauv lawv cov interrupter chamber yog heev tsawg (kwv yees li 10⁻² txog 10⁻⁴ Pa), mus txog qhov tseeb nqus. Thaum cov kev sib cuag ib feem, lub arc yog tsim los ntawm cov hlau vapor. Vim hais tias lub tshuab nqus tsev nruab nrab muaj qhov siab heev dielectric rov qab ceev (txog li kaum ntawm kV / μs), thiab cov vapor hais tawm sai sai rau sab nraud thiab condense ntawm arc shield, lub zog dielectric hla qhov sib txawv rov qab sai sai tom qab xoom tam sim no, thiab lub arc extinguishes lawm.
Tag nrho cov txheej txheem cuam tshuam tsis muaj roj ntws; Hloov chaw, nws tso siab rau lub tshuab nqus tsev tus kheej zoo heev rwb thaiv tsev thiab diffusion peev xwm.
Cov ntsiab lus
Txawm hais tias lub arc-quenching mechanisms ntawm ob hom breakers yog qhov sib txawv, ob qho tib si tuaj yeem cuam tshuam qhov luv-circuit tam sim no.
Nqus Circuit Court breakersTsis muaj kev pheej hmoo ntawm cov pa paug thiab kev saib xyuas yooj yim, tau siv dav hauv nruab nrab-voltage tis networks, thaum SF₆ breakers, vim lawv muaj peev xwm cuam tshuam, feem ntau yog ua haujlwm hauv high-voltage thiab extra-high-voltage kis systems.
Tawm tsam keeb kwm yav dhau los ntawm "dual carbon" cov hom phiaj, ib puag ncig tus phooj ywgLub tshuab nqus tsev Circuit Court breakerstau maj mam hloov qee cov khoom siv SF₆, dhau los ua qhov kev xaiv tseem ceeb rau daim phiaj hluav taws xob ntsuab.
