A Circuit Court breakeryog cov khoom siv hluav taws xob feem ntau siv hauv AC circuits.Cov qauv siv hluav taws xob feem ntau yog tsim los ntawm kev sib tiv tauj, kev sib tiv tauj thiab kev sib cuag zoo li qub.Hauv ib lub voj voog, cov qauv siv hluav taws xob tuaj yeem txiav tawm lub hwj chim, txuas cov khoom siv hluav taws xob thiab tiv thaiv cov khoom siv hluav taws xob.Raws li nws cov qauv thiab cov qauv kev ua haujlwm, nws tuaj yeem muab faib uaib-theem Circuit Court breaker, peb-theem Circuit Court breaker thiabcua Circuit Court breaker.Circuit Court breaker, raws li cov cuab yeej cuam tshuam ntawm kev tswj Circuit Court thiab lub zog hluav taws xob, plays lub luag haujlwm tseem ceeb hauv daim phiaj hluav taws xob.Thaum lub Circuit Court overload, luv luv Circuit Court thiab lwm yam txhaum, kev tiv thaiv ntawm hluav taws xob raws sij hawm yuav raug txiav tawm, kom lub Circuit Court qhib los tiv thaiv tus kheej thiab cov khoom muaj kev ruaj ntseg thiab lwm yam khoom los ntawm kev puas tsuaj.Yog li ntawd covCircuit Court breakerdav siv nyob rau hauv lub hwj chim system tseem hu ua "over-undervoltage protector" los yog "fuse".Ib qho ntawm cov haujlwm tseem ceeb yog txiav tawm lub zog hluav taws xob thaum muaj qhov luv luv.
Txoj cai ntawm kev ua haujlwm
Thaum lub AC tam sim no los ntawm kev sib cuag ntawm lub Circuit Court breaker, electromagnetic attraction, tsav qhov kev txiav txim ntawm kev khiav hauj lwm mechanism, kom lub Circuit Court breaker tso tawm tripping, yog li txiav lub Circuit Court.
Hauv kev xyaum, lub cuab yeej ncua sij hawm tuaj yeem raug ntxiv kom lub voj voog tuaj yeem raug txiav tawm tsuas yog tom qab qhov kev hloov pauv ua tiav hauv lub sijhawm teem tseg.
Thaum lub luv luv Circuit Court tam sim no dhau los ntawm Circuit Court breaker, cov hlau nyob ze ntawm kev sib cuag yog melted thiab rub tawm los ntawm thermal tso tawm vim lub arc kinetic zog thiab khaus cua sov generated los ntawm melting ntawm kev sib cuag, yog li txiav tawm tam sim no.
Thaum lub hwj chim hloov raug kaw los yog lub voj voog txuas nrog nws tsis ua haujlwm, lub tshuab hluav taws xob tuaj yeem tawg lub voj voog hauv lub sijhawm luv luv.
Raws li cov qauv tsim tau muab faib ua taag, mobile thiab ncua peb.
Raws li kev tso tawm hom yog muab faib ua phau ntawv thiab hluav taws xob ob daim ntawv.
Raws li kev khiav hauj lwm mechanism tuaj yeem muab faib ua txoj siv sib kis thiab tsis siv txoj siv sia siv ob hom;
Kev faib tawm
(1)Circuit Court breakerstuaj yeem muab faib ua lub tshuab nqus tsev vacuum interrupter chamber (VHV), arc interrupter gate (AVR), lub tshuab nqus tsev (VSD) thiab lub tshuab nqus tsev contactor raws li qhov nruab nrab ntawm arc interrupter.
(2) Circuit Court breakers tuaj yeem muab faib ua peb hom: ib-theem Circuit Court breaker, peb-theem Circuit Court breaker thiab cua Circuit Court breaker.
(3) Cua Circuit Court breakers tuaj yeem muab faib ua ob hom, AC thiab DC, raws li cov neeg siv khoom thiab qhov chaw sib txawv ntawm kev siv.
(4) Lub tshuab hluav taws xob tuaj yeem ua ke nrog lub tshuab hluav taws xob cua tshuab hluav taws xob, cua inductor thiab lwm yam khoom siv hluav taws xob raws li txoj kev teeb tsa, thiab tuaj yeem siv los ua cov khoom siv hluav taws xob tiv thaiv.
(5) Lawv tau muab faib ua hom kev tiv thaiv tshaj tam sim no, luv-circuit tiv thaiv hom thiab tshaj-hauv-voltage tiv thaiv hom raws li lawv cov yam ntxwv tiv thaiv.
(6) Muaj 100V series dav dav-lub hom phiaj cua qhov hluav taws xob thiab qib tam sim no raws li lawv cov ntsuas hluav taws xob thiab cov nqi tam sim no.
Specification parameter
Hom hluav taws xob hluav taws xob zoo ib yam li lwm yam khoom siv hluav taws xob, xws li cov lej tsim los ntawm cov tsiaj ntawv "P", "Y" thiab cov lej rau kev hloov pauv, thiab cov lej tsim los ntawm tsab ntawv "C" thiab tus lej rau riam hloov , thiab lwm yam, tab sis lawv cov dej num thiab cov qauv yog qhov sib txawv thiab feem ntau tsis tuaj yeem siv rau lub hom phiaj dav dav.Piv txwv li ZF6 thiab ZF14.
2) Rated voltage: yog hais txog tus nqi ntsuas uas lub Circuit Court breaker tuaj yeem dais nyob rau hauv qhov ntsuas zaus (50Hz) thiab qhov ntsuas zaus (25Hz).
3) Rated tam sim no: yog hais txog lub siab tshaj plaws ua hauj lwm tam sim no uas lub Circuit Court breaker tuaj yeem tiv taus raws li cov xwm txheej.
4. "Breaking peev" txhais tau hais tias lub Circuit Court breaker tuaj yeem ntseeg tau qhov kev sib txuas ntawm AC 50Hz lossis DC 1000V lossis qis dua raws li cov kev cai, thiab lub sijhawm tawg yuav tsum tsis pub tshaj 5ms.
5) Cov yam ntxwv ua haujlwm
Txoj cai ntawm kev xaiv
1. Faib rau hauv:
(1) Ib-theem Circuit Court breakers yog siv rau kev tiv thaiv circuits, motors thiab lwm yam khoom siv hluav taws xob.Lub Circuit Court breaker muaj qhov zoo ntawm kev ua haujlwm tsis tu ncua thiab yooj yim, tab sis nws yuav tsum tau txiav tawm lub zog hluav taws xob hauv lub sijhawm thaum cov kab thiab lub cev muaj zog dhau los lossis luv luv los tiv thaiv kev sib tsoo ntawm kev nthuav dav.Yog li ntawd, lub Circuit Court breaker yuav tsum tau raws li qhov yuav tsum tau ntawm kev txiav tawm lub hwj chim mov nyob rau hauv lub sij hawm teem, nrog luv luv breaker lub sij hawm, zoo xaiv thiab thiaj li nyob.
(2) Lo lus "peb-theem AC low-voltage Circuit Court breaker" yog hais txog lub tshuab hluav taws xob siv hluav taws xob siv hauv kev tiv thaiv lub cev muaj zog thiab kev tswj xyuas hluav taws xob, uas muaj qhov ua haujlwm zoo ib yam li ib-theem Circuit Court breaker, tab sis tau ntxiv ib qho kev hloov pauv mus rau lub tshuab hluav taws xob. Cov qauv sab hauv ntawm cov khoom siv hluav taws xob kom ua tau raws li qhov yuav tsum tau muaj rau kev tiv thaiv lub cev muaj zog thiab kev tswj xyuas hauv AC circuits.Tsis tas li ntawd, nws kuj tseem muaj overload relay, undervoltage relay thiab xoom sequence tam sim no relay.
