Hauv -Kev tsom xam qhov tob ntawm lub tshuab nqus tsev vacuum breakers

Nqus Circuit Court breakersyog Circuit Court breakers uas siv lub tshuab nqus tsev ua lub arc - tua thiab insulating nruab nrab. Lawv muaj qhov zoo xws li cov qauv hnyav, kev ua haujlwm yooj yim, thiab kev saib xyuas yooj yim. Cov hauv qab no yog hauv - tsom xam qhov tob ntawm lawv cov yam ntxwv tseem ceeb:

Core Structure thiab Txoj Cai Ua Haujlwm

Nqus Interruptor: Cov ntsiab lus tseem ceeb, muaj lub plhaub airtight insulating, conductive circuit, bellows, thiab lwm yam. Lub tshuab nqus tsev yuav tsum tsis pub tsawg tshaj 10⁴ Torr kom muaj zog rwb thaiv tsev. Qhov sib tiv tauj me me (piv txwv li, tsuas yog 10mm rau 10kV), siv lub tshuab nqus tsev kom ceev ceev tua cov arc.

Arc Extinguishing Mechanism

Me me tam sim no Arc: Cov hlau nyob rau hauv cov kev sib cuag evaporates tsim plasma; lub arc extinguishes lawm thaum tam sim no hla xoom.

Loj tam sim no Arc: Lub arc yog tig thiab diffused los ntawm ib tug longitudinal magnetic teb (xws li, generated los ntawm grooves nyob rau hauv ib lub khob-zoo li tus tiv tauj), txo kev sib cuag burn- tawm.

Cov yam ntxwv tseem ceeb

Performance Advantages: Lub teeb yuag thiab compact qauv, ua haujlwm yooj yim.

Lub sij hawm luv luv (ib nrab- voj voog Circuit Court breaker), kev tiv tauj tsawg dua, lub neej ua haujlwm ntev.

Kev saib xyuas yooj yim, tiv thaiv hluav taws thiab tawg- pov thawj, tsis muaj suab nrov.

Technological Breakthroughs: Qhia longitudinal magnetic field technology nyob rau hauv 1980s, ho txhim kho lub peev xwm tawg thiab tiv taus voltage.

Siv cov ntaub ntawv tiv tauj tshiab xws li tooj liab -chromium alloy, txo qhov tam sim no - txiav tus nqi (3 ~ 5A), thiab txhim kho cov teeb meem overvoltage ntawm inductive load lag luam.

Kev thov thiab kev tu

Voltage Level: Feem ntau siv hauv nruab nrab-voltage (10kV ~ 40.5kV) lub zog hluav taws xob, xws li qauv ZN7-10 thiab ZN28-10A.

Cov Ntsiab Lus Kho: Tsis tu ncua xyuas lub tshuab nqus tsev kom tsis txhob muaj cua nkag los ntawm kev cuam tshuam lub peev xwm tawg.

Ua tib zoo saib rau lub sijhawm kaw bounce (tsawg dua lossis sib npaug li 3ms) kom tsis txhob cuam tshuam rau lub arc - tua chamber lub neej.

Txoj Kev Loj Hlob

Kev txhim kho yav tom ntej yuav tsom mus rau cov kev txawj ntse thiab cov qauv tsim me me kom tau raws li qhov siab -kev ua tau zoo thiab kev nyab xeeb ntawm cov tshuab hluav taws xob.
