Circuit Court breakerFeem ntau yog tsim los ntawm kev sib txuas lus, lub tshuab hluav taws xob tua hluav taws xob, lub tshuab ua haujlwm, ib qho chaw mus ncig, thiab lub casing.
Lub luag haujlwm ntawm lub Circuit Court breaker yog txiav tawm thiab txuas lub load Circuit Court, thiab txiav tawm lub faulty Circuit Court, thiaj li tiv thaiv kev nthuav dav ntawm kev sib tsoo thiab ua kom muaj kev nyab xeeb.Lub high-voltage Circuit Court breaker yuav tsum tau tawg 1500V, thiab tam sim no yog 1500-2000A arc, thiab cov arcs tuaj yeem ncav cuag 2m thiab tseem kub hnyiab tsis tas yuav tua.Yog li ntawd, arc extinguishing yog ib qho teeb meem uas yuav tsum tau daws rau high voltage Circuit Court breakers.
Tsawg-voltage Circuit Court breakers, kuj hu ua automaticcua hloov, tuaj yeem siv los hloov thiab tawm cov khoom siv hluav taws xob, thiab tseem tuaj yeem siv los tswj cov motors uas pib tsis tshua muaj.Nws txoj haujlwm yog sib npaug rau cov lej ntawm qee qhov lossis tag nrho cov haujlwm ntawm cov riam hloov, dhau tam sim no relay, voltage poob relay, thermal relay thiab to tiv thaiv.Nws yog ib qho tseem ceeb tiv thaiv ntaus ntawv nyob rau hauv lub low-voltage tis network.
Tsawg-voltage Circuit Court breakers muaj ntau yam kev tiv thaiv (overload,luv luv, undervoltage tiv thaiv, thiab lwm yam.), adjustable khiav hauj lwm tus nqi, siab tawg peev xwm, yooj yim ua hauj lwm, kev nyab xeeb, thiab lwm yam., yog li ntawd lawv yog dav siv.Cov qauv thiab kev ua haujlwm hauv paus ntsiab lus qis-voltage Circuit Court breaker yog tsim los ntawm kev khiav hauj lwm mechanism, kev sib cuag, cov khoom siv tiv thaiv (ntau qhov tso tawm), arc extinguishing system thiab lwm yam.
Lub ntsiab tiv tauj ntawm qhov hluav taws xob qis hluav taws xob yog kaw manually lossis hluav taws xob.Tom qab lub ntsiab kev sib cuag raug kaw, lub free tripping mechanism xauv lub ntsiab kev sib cuag nyob rau hauv lub kaw txoj hauj lwm.Lub coil ntawm lub overcurrent tso tawm thiab lub thermal caij ntawm lub thermal tso tawm yog kev cob cog rua nyob rau hauv series nrog lublub ntsiab Circuit Court,thiab lub coil ntawm lub undervoltage tso tawm yog txuas nrog nyob rau hauv parallel nrog lub hwj chim mov.Thaum lub voj voog luv luv lossis hnyav dhau lawm, lub armature ntawm qhov kev tso tawm tshaj tawm tam sim no yuav rub tawm los ua kom muaj kev ywj pheej ywj pheej, thiab qhov kev sib cuag tseem ceeb yuav cuam tshuam lub ntsiab Circuit Court.Thaum lub Circuit Court yog overloaded, lub thermal caij ntawm lub thermal tso tawm yuav ua kom cua sov los khoov daim ntawv bimetal, thawb lub free release mechanism los ua.Thaum lub Circuit Court yog undervoltage, lub armature ntawm lub undervoltage tso tawm.Kuj activates lub free tripping mechanism.Lub shunt tso tawm yog siv rau cov chaw taws teeb tswj.Thaum lub sijhawm ua haujlwm ib txwm, nws lub kauj yog powered.Thaum yuav tsum tau tswj kev deb, nias lub pob pib kom lub zog ntawm lub kauj.
