Tsawg-voltage Circuit Court breaker chwv lub ntsiab yog khi tes hloov qhov kev tuav los yog fais. Tom qab cov
neeg tseem ceeb raug kaw, tsis pub mus txawv tebchaws mechanism rau cov hom neeg muab tub nyob rau hauv lub
txoj hauj lwm kaw. Overcurrent tso kauj thiab tripping tus thermal cheebtsam hauv series
nrog Circuit Court, undervoltage tawm kauj thiab hwj huam khoom siv hauv mus tib seem.
Thaum twg tus Circuit Court yog shorted los yog loj tshaj, overcurrent tawm armature absorbs,
dawm-dawb mechanism loj hu disconnect hauv Circuit Court.
Thaum cov Circuit Court sib tshooj, tripping tus tshaj rau lub caij bimetallic bends,
tsav mus txawv tebchaws tsis pub mechanism loj hu disconnect hauv Circuit Court.
Thaum cov Circuit Court hauv voltage, undervoltage tso cov ntsis tso, tsis pub mus txawv tebchaws mechanism
cov neeg tseem ceeb disconnect hauv Circuit Court.
Thaum lub pob yog pressed nrau shunt thiab shunt tawm armature absorbs, txawv tebchaws tsis pub
mechanism loj hu disconnect hauv Circuit Court.
Kev faib tawm
Tsawg-voltage Circuit Court tej fais fab dej num raws li nyias quenching nruab nrab, siv
cua li ib breaker ntawm qhov nruab nrab extinguishing, peb paub los lawm raws li cov ACB (pa mus), siv ib qho inert
roj li tej fais fab ntawm qhov nruab nrab extinguishing, hu ua inert gas Circuit Court tej fais fab (noble roj mus),
siv cov roj ua ib breaker ntawm qhov nruab nrab extinguishing, hu roj Circuit Court tej fais fab (roj mus).
