Dab tsi yog lub luag haujlwm ntawm Circuit Court breaker, lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm Circuit Court breaker yog cov lus piav qhia ntxaws
Thaum lub kaw lus ua tsis tiav, kev tiv thaiv kev ua txhaum ntawm cov khoom txhaum cai thiab kev ua haujlwm tsis zoo ntawm Circuit Court breaker tsis kam mus ncig, mus rau qhov chaw nyob ib puag ncig ntawm lub substation los ntawm kev tiv thaiv ntawm qhov txhaum, thiab cov channel tseem tuaj yeem siv los ua cov xaim hluav taws xob. lub distal circuit breaker mus txawv tebchaws nyob rau tib lub sij hawm yog hu ua lub Circuit Court breaker tsis ua hauj lwm tiv thaiv.
Feem ntau, tom qab qhov kev txiav txim ntawm cov theem tam sim no, ob pawg ntawm cov ntsiab lus pib sib cuag yog cov khoom tso tawm, thiab cov kev tiv thaiv sab nraud tiv thaiv cov ntsiab lus txuas nrog hauv cov kab hauv Circuit Court, tsheb npav txuas lossis ntu Circuit Court breaker tsis ua haujlwm los pib tiv thaiv tsis ua haujlwm.
Dab tsi yog cov haujlwm ntawm cov hluav taws xob hluav taws xob
Circuit Court breakers feem ntau yog siv nyob rau hauv nquag motors thiab muaj peev xwm loj transformers thiab substations.Circuit Court breaker muaj kev ua haujlwm ntawm kev faib cov khoom sib tsoo, thiab koom tes nrog ntau yam kev tiv thaiv relay los tiv thaiv cov khoom siv hluav taws xob lossis kab.
Circuit Court breaker feem ntau yog siv nyob rau hauv cov teeb pom kev zoo uas tsis muaj hluav taws xob, lub zog hluav taws xob, tuaj yeem ua lub luag haujlwm ntawm kev txiav tawm hauv Circuit Court;Circuit Court breaker thiab overload thiab luv Circuit Court tiv thaiv thiab ntau lwm yam kev khiav dej num, tab sis qhov qis load teeb meem yuav tsum tau kho yog lub disconnecting hloov plays ib tug hluav taws xob cais lub luag hauj lwm, thiab lub Circuit Court breaker creepage deb tsis txaus.
Tam sim no muaj lub Circuit Court breaker nrog kev sib cais muaj nuj nqi, uas yog qhov zoo tib yam Circuit Court breaker thiab disconnector muaj nuj nqi ob hauv ib qho.Lub Circuit Court breaker nrog kev sib cais muaj nuj nqi kuj tuaj yeem yog lub cev disconnector.Qhov tseeb, qhov kev hloov pauv feem ntau tsis ua haujlwm nrog kev thauj khoom, thaum lub tshuab hluav taws xob muaj luv luv, kev tiv thaiv overload, underpressure thiab lwm yam kev tiv thaiv.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm Circuit Court breaker yog nthuav dav
Yam yooj yim: Cov cuab yeej tiv thaiv hluav taws xob yooj yim tshaj plaws yog lub fuse.Lub fuse tsuas yog ib qho nyias nyias, nrog rau cov ntaub ntawv tiv thaiv thiab tom qab ntawd txuas nrog lub voj voog.Tom qab lub Circuit Court raug kaw, tag nrho cov tam sim no yuav tsum ntws los ntawm lub tam sim no ntawm lub fuse —— fuse li tib yam tam sim no ntawm lwm cov ntsiab lus ntawm tib lub Circuit Court.Lub fuse yog tsim los kom nws muaj peev xwm fuse thaum kub nce mus txog ib theem.Burrowing lub fuse tuaj yeem ua rau txoj kev qhib kom tsis txhob muaj ntau dhau tam sim no los ntawm kev puas tsuaj rau lub tsev thaiv.Qhov teeb meem nrog lub fuse yog tias nws tuaj yeem ua haujlwm ib zaug xwb.Thaum twg lub fuse raug hlawv, nws yuav tsum tau hloov.Circuit Court breakers tuaj yeem ua tib lub luag haujlwm li fuses, tab sis lawv tuaj yeem siv tau ntau zaus.Sai li qhov tam sim no nce mus txog qib txaus ntshai, nws tam sim ntawd ua rau qhib Circuit Court.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm: cov hluav taws xob hauv hluav taws xob txuas nrog rau ob qho kawg ntawm qhov hloov.Thaum qhov hloov pauv tau muab tso rau hauv lub xeev, qhov tam sim no ntws tawm ntawm lub davhlau ya nyob twg hauv qab, ua tiav los ntawm lub cev hluav taws xob, kev sib cuag ntawm tes, kev sib cuag zoo li qub, thiab thaum kawg los ntawm lub davhlau ya nyob twg sab saum toj.Qhov tam sim no tuaj yeem tsim cov hlau nplaum electromagnetic.Lub zog sib nqus ua los ntawm cov hlau nplaum electromagnetic nce nrog qhov tam sim no, thiab yog tias tam sim no txo qis.Thaum qhov tam sim no dhia mus rau theem txaus ntshai, EM kev paub ua rau lub zog sib nqus loj txaus los rub cov pas hlau txuas nrog rau kev sib txuas ntawm kev sib txuas.Qhov no ua rau lub txav contactor qaij thiab tawm ntawm tus contactor zoo li qub, tom qab ntawd txiav tawm lub voj voog.Cov hluav taws xob tam sim no tseem cuam tshuam.Lub bimetal bar yog tsim los ntawm tib lub hauv paus ntsiab lus, qhov sib txawv yog tias tsis tas yuav muab lub zog hluav taws xob hauv lub cev ntawm no, tab sis tso cai rau cov hlau bar khoov ntawm lub siab tam sim no, thiab tom qab ntawd pib cov khoom sib txuas.Qee qhov hluav taws xob hluav taws xob kuj tseem muaj cov khoom tawg kom txav mus los.Thaum qhov tam sim no tshaj ib theem, nws ignites cov khoom tawg thiab ces tsav lub piston mus qhib qhov hloov.
Cov qauv ua kom zoo dua: Ntau qhov kev tshaj tawm Circuit Court breakers tso tseg cov khoom siv hluav taws xob yooj yim thiab siv cov khoom siv hluav taws xob (semiconductor devices) los saib xyuas qib tam sim no.Hauv av txhaum Circuit Court breaker (GFCI) yog ib hom tshiab ntawm Circuit Court breaker.Qhov hluav taws xob hluav taws xob no tuaj yeem tsis tsuas yog tiv thaiv kev puas tsuaj rau lub tsev thaiv, tab sis kuj tiv thaiv tib neeg los ntawm hluav taws xob shocks.
Txhim kho kev ua haujlwm: GFCI tas li saib xyuas qhov tam sim no ntawm xoom thiab hluav taws kab hauv Circuit Court.Thaum txhua yam zoo li qub, tam sim no ntawm ob kab yuav tsum zoo ib yam.Thaum cov kab hluav taws xob ncaj qha mus rau hauv av (piv txwv li, ib tus neeg cuam tshuam rau kab hluav taws), qhov tam sim no ntawm kab hluav taws tau nce, thaum lub xoom kab tsis ua.GFCI txiav tawm lub voj voog tam sim tom qab kuaj pom tus mob no los tiv thaiv kev poob hluav taws xob.Vim tias GFCI tuaj yeem nqis tes ua yam tsis tau tos kom txog thaum tam sim no nce mus rau theem txaus ntshai, nws cuam tshuam sai dua li cov kab hluav taws xob sib txuas.
