Thaum muaj kev txhaum tshwm sim nyob rau hauv lub kaw lus, kev tiv thaiv ntawm lub txim txhaum ua thiab nws cov Circuit Court breaker tsis mus txawv tebchaws, kev tiv thaiv ntawm lub txim txhaum ua rau lub Circuit Court breaker nyob ib sab ntawm lub substation mus txawv tebchaws, thiab yog hais tias tej yam kev mob tso cai, lub channel yuav ua tau. siv los ua kom muaj feem cuam tshuam nrog Circuit Court breakers ntawm qhov chaw taws teeb kawg tib lub sijhawm.Cov kab hluav taws xob tripped hu ua breaker tsis ua haujlwm tiv thaiv.
Feem ntau, tom qab lub caij tam sim no txiav txim los ntawm theem kev sib cais ua haujlwm, ob pawg ntawm kev sib txuas pib yog cov khoom tso tawm, uas tau txuas nrog cov kev tiv thaiv sab nraud los tiv thaiv qhov pib tsis ua haujlwm thaum txoj kab, tsheb npav khi lossis ntu Circuit Court breaker tsis ua haujlwm.
Dab tsi yog cov haujlwm ntawm Circuit Court breakers
Circuit breakers feem ntau yog siv rau hauv cov motors, loj-muaj peev xwm transformers thiab substations uas nquag tawg loads.Lub Circuit Court breaker muaj lub luag haujlwm ntawm kev tawg qhov kev 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 breakers feem ntau yog siv nyob rau hauv qhov hluav taws xob tsis tshua muaj teeb pom kev zoo thiab lub zog hluav taws xob qhov chaw, uas tuaj yeem txiav tawm hauv Circuit Court;Circuit Court breakers kuj muaj ntau yam haujlwm xws li overload thiab luv-circuit tiv thaiv, tab sis ib zaug muaj teeb meem nrog lub load ntawm qis kawg, yuav tsum tau saib xyuas.Lub luag hauj lwm ntawm lub Circuit Court breaker, thiab lub creepage deb ntawm lub Circuit Court breaker tsis txaus.
Tam sim no muaj lub Circuit Court breaker nrog kev sib cais muaj nuj nqi, uas sib txuas ua haujlwm ntawm ib qho hluav taws xob hluav taws xob zoo tib yam thiab kev sib cais hloov.Lub Circuit Court breaker nrog kev sib cais muaj nuj nqi kuj tuaj yeem yog qhov hloov pauv ntawm lub cev.Qhov tseeb, qhov hloov pauv feem ntau tsis tuaj yeem ua haujlwm nrog kev thauj khoom, thaum lub tshuab hluav taws xob muaj kev tiv thaiv xws li luv luv Circuit Court, tiv thaiv overload, undervoltage thiab lwm yam.
Cov lus piav qhia ntxaws txog txoj hauv kev ua haujlwm ntawm Circuit Court breakers
Basic: Cov khoom siv tiv thaiv hluav taws xob yooj yim tshaj plaws yog lub fuse.Lub fuse tsuas yog ib txoj hlua nyias nyias, nrog cov hlua tiv thaiv txuas rau hauv Circuit Court.Thaum lub Circuit Court raug kaw, tag nrho cov tam sim no yuav tsum ntws los ntawm lub fuse - qhov tam sim no ntawm lub fuse yog tib yam li tam sim no ntawm lwm cov ntsiab lus ntawm tib lub voj voog.Qhov fuse no yog tsim los tshuab thaum kub nce mus txog ib theem.Lub tshuab hluav taws xob tuaj yeem tsim kom muaj qhov qhib hluav taws xob uas tiv thaiv cov hluav taws xob ntau dhau los ntawm kev puas tsuaj hauv tsev.Qhov teeb meem nrog lub fuse yog tias nws tsuas ua haujlwm ib zaug xwb.Thaum twg lub fuse raug tshuab, nws yuav tsum tau hloov nrog ib qho tshiab.Lub Circuit Court breaker tuaj yeem ua haujlwm zoo ib yam li lub fuse, tab sis tuaj yeem siv tau ntau zaus.Ntev npaum li qhov tam sim no nce mus txog qib txaus ntshai, nws tuaj yeem tsim qhov qhib Circuit Court tam sim.
Lub hauv paus ntsiab lus ua haujlwm: Cov hlau nyob hauv lub voj voog txuas nrog rau ob qho kawg ntawm qhov hloov.Thaum qhov hloov pauv tau muab tso rau hauv lub xeev ON, tam sim no ntws los ntawm lub davhlau ya nyob twg hauv qab, los ntawm electromagnet, txav contactor, tus contactor zoo li qub, thiab thaum kawg lub davhlau ya nyob twg sab saum toj.Cov tam sim no tuaj yeem ua kom cov electromagnet.Lub zog sib nqus ua los ntawm electromagnet nce raws li qhov tam sim no nce, thiab yog tias tam sim no txo qis, qhov sib nqus quab yuam txo.Thaum tam sim no dhia mus rau theem txaus ntshai, lub electromagnet tsim kom muaj zog sib nqus txaus los rub ib lub pas hlau txuas rau qhov kev sib txuas.Qhov no tilts lub txav contactor kom deb ntawm tus contactor zoo li qub, tawg lub voj voog.Tam sim no kuj cuam tshuam.Kev tsim ntawm bimetal strips yog raws li tib lub hauv paus ntsiab lus, qhov sib txawv yog tias es tsis txhob siv cov khoom siv hluav taws xob, cov strips raug tso cai khoov ntawm lawv tus kheej nyob rau hauv siab tam sim no, uas nyob rau hauv lem activates lub linkage.Lwm cov Circuit Court breakers tau ntim nrog cov khoom tawg kom tshem tawm qhov hloov.Thaum qhov tam sim no tshaj ib theem, cov khoom tawg yog ignited, uas nyob rau hauv lem drives lub piston qhib qhov hloov
Txhim kho: Ntau qhov kev tshaj tawm hauv Circuit Court breakers tshem tawm nrog cov khoom siv hluav taws xob yooj yim hauv kev pom zoo ntawm cov khoom siv hluav taws xob (semiconductor devices) los saib xyuas qib tam sim no.Kev cuam tshuam hauv av txhaum kev cuam tshuam (GFCI) yog ib hom tshiab ntawm Circuit Court breaker.Qhov no Circuit Court breaker tsis tsuas yog tiv thaiv kev puas tsuaj rau cov xaim hauv tsev, tab sis kuj tiv thaiv tib neeg los ntawm hluav taws xob shocks.
Txhim kho txoj haujlwm ua haujlwm: GFCI tas li saib xyuas qhov tam sim no ntawm cov xov hlau nruab nrab thiab nyob hauv Circuit Court.Thaum txhua yam zoo, tam sim no yuav tsum yog tib yam ntawm ob lub xov hlau.Thaum cov hlau nyob ncaj qha mus rau hauv av (xws li ib tug neeg raug chwv cov hlau nyob), qhov tam sim no ntawm cov hlau nyob yuav dheev ntsoos ntsoos, tab sis cov hlau nruab nrab yuav tsis.GFCI tam sim ntawd kaw lub voj voog thaum kuaj pom tus mob no los tiv thaiv kev raug mob hluav taws xob.Vim tias GFCI tsis tas yuav tos qhov tam sim no nce mus rau theem txaus ntshai los ua, nws hnov mob sai dua li cov tsoos hluav taws xob.
