icro Circuit Breaker (MCB luv luv) yog ib qho ntawm cov khoom siv dav siv dav siv hauv kev tiv thaiv hluav taws xob hauv hluav taws xob hluav taws xob hluav taws xob. Nws feem ntau yog siv rau ib-theem thiab peb-theem luv luv Circuit Court, overload thiab tshaj-voltage tiv thaiv hauv qab 125A, thiab feem ntau muaj nyob rau hauv ib tug ncej, ob-ncej, peb-ncej thiab plaub-ncej xaiv. Lub luag haujlwm tseem ceeb ntawm lub tshuab hluav taws xob me me (MCB) yog hloov lub voj voog, piv txwv li thaum tam sim no los ntawm qhov hluav taws xob me me Circuit Court breaker (MCB) tshaj tus nqi teev los ntawm nws, nws yuav txiav tawm Circuit Court tom qab lub sijhawm ncua sijhawm. Yog tias xav tau, nws tseem tuaj yeem hloov lub Circuit Court rau thiab tawm manually zoo li ib txwm hloov.
Miniature Circuit Breaker (MCB) Cov Qauv thiab Cov Cai Ua Haujlwm
Miniature Circuit Breakers (MCB) yog ua los ntawm cov khoom siv thermoplastic insulating molded nyob rau hauv ib lub tsev uas muaj cov khoom zoo, thermal thiab insulating zog. Lub tshuab hloov pauv muaj qhov ruaj khov zoo li qub thiab txav tau cov neeg sib cuag nrog cov neeg thiab cov khoom siv hluav taws xob txuas nrog ua ke thiab thauj khoom terminals. Cov kev sib cuag thiab cov khoom nqa tam sim no yog ua los ntawm electrolytic tooj liab lossis nyiaj alloys, qhov kev xaiv yog nyob ntawm qhov ntsuas hluav taws xob tam sim no ntawm lub Circuit Court breaker.
Thaum kev sib cuag sib cais nyob rau hauv overload los yog luv luv Circuit Court tej yam kev mob, ib tug arc yog tsim. Niaj hnub nimno tej yam me me Circuit Court breaker (MCB) yog siv los cuam tshuam los yog tshem tawm cov arc tsim, arc zog nqus thiab txias los ntawm lub arc extinguishing chamber nyob rau hauv cov hlau arc spacer kom paub, cov arc spacers nrog insulated bracket tsau nyob rau hauv qhov tsim nyog txoj hauj lwm. Tsis tas li ntawd, kev siv cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob (circuit breakers tam sim no ntau qhov kev txwv tam sim no los txhim kho lub peev xwm tawg ntawm cov khoom) lossis sib nqus tshuab, kom lub arc txav nrawm thiab elongated, los ntawm arc txaus channel mus rau hauv lub interrupter chamber. .
Miniature Circuit Breaker (MCB) kev khiav hauj lwm mechanism muaj xws li solenoid magnetic tso tawm ntaus ntawv thiab bimetal thermal tso ntaus ntawv. Cov cuab yeej sib nqus stripping yog qhov sib nqus hluav taws xob. Thaum ib txwm tam sim no dhau mus rau hauv txoj kab, lub zog hluav taws xob tsim los ntawm solenoid tsawg dua lub caij nplooj ntoos hlav nro los ua ib qho kev quab yuam, lub armature tsis tuaj yeem nqus los ntawm solenoid, thiab lub Circuit Court breaker ua haujlwm ib txwm. Thaum muaj qhov cuam tshuam luv luv ntawm txoj kab, qhov tam sim no dhau ntau zaus ntawm qhov qub tam sim no, lub zog hluav taws xob tsim los ntawm electromagnet ntau dua li cov tshuaj tiv thaiv lub caij nplooj ntoos hlav, lub armature yog nqus los ntawm electromagnet los ntawm kev sib kis. mechanism los txhawb qhov kev tso tawm dawb mechanism tso tawm cov neeg tseem ceeb. Kev sib cuag tseem ceeb yog sib cais nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav tawg kom txiav tawm Circuit Court los ua lub luag haujlwm ntawm kev tiv thaiv luv luv.
Cov khoom tseem ceeb hauv cov khoom siv thermal tso tawm yog bimetal, uas feem ntau yog nias los ntawm ob hom hlau sib txawv lossis cov hlau alloys. Hlau los yog hlau alloy muaj cov yam ntxwv, uas yog, sib txawv hlau los yog hlau alloy nyob rau hauv cov ntaub ntawv ntawm tshav kub, lub expansion ntawm lub ntim hloov tsis zoo ib yam, yog li thaum nws yog rhuab, rau ob yam khoom sib txawv hlau los yog alloy muaj pes tsawg leeg ntawm bimetallic. daim ntawv, nws yuav yog mus rau expansion coefficient ntawm sab ntawm lub qis sab ntawm lub dabtsi yog khoov, siv curvature los txhawb kev tso tawm ntawm tus pas nrig teb txav, kev siv ntawm kev tso tawm tripping kev txiav txim, thiaj li mus paub lub overload. kev tiv thaiv. Txij li kev tiv thaiv overload yog pom los ntawm cov nyhuv thermal, nws tseem hu ua thermal tso tawm.
Kev xaiv ntawm 1, 2, 3 thiab 4 tus ncej ntawm cov khoom siv hluav taws xob me me
Ib-ncej me me Circuit Court breakers yog siv los muab kev hloov thiab kev tiv thaiv rau ib theem ntawm ib lub voj voog. Cov hluav taws xob hluav taws xob no feem ntau yog tsim los rau cov hluav taws xob hluav taws xob tsawg. Cov hluav taws xob hluav taws xob no pab tswj cov xov hlau tshwj xeeb, cov teeb pom kev zoo lossis cov hluav taws xob hauv tsev. Cov no tseem tuaj yeem siv rau lub tshuab nqus tsev, lub teeb pom kev dav dav, teeb pom kev zoo sab nraum zoov, kiv cua thiab tshuab tshuab thiab lwm yam.
Ob chav ncej me me Circuit Court breakers feem ntau yog siv rau hauv cov neeg siv khoom tswj vaj huam sib luag xws li cov keyboards loj. Pib los ntawm lub zog ntsuas hluav taws xob, lub zog tau tawg mus thoob plaws hauv Circuit Court breaker mus rau ntau qhov chaw ntawm lub tsev. Ob chav ncej me me Circuit Court breakers yog siv los muab kev tiv thaiv thiab hloov rau theem thiab nruab nrab ntawm cov xov hlau.
Peb-ncej me me Circuit Court breakers yog siv los muab kev hloov pauv thiab kev tiv thaiv tsuas yog peb theem ntawm Circuit Court, tsis yog qhov nruab nrab.
Ib tug plaub-ncej me me Circuit Court breaker, ntxiv rau muab kev hloov thiab kev tiv thaiv rau peb theem ntawm lub voj voog, muaj kev tiv thaiv feem ntau rau cov ncej nruab nrab (piv txwv li, N ncej). Yog li ntawd, ib tug plaub-ncej me me Circuit Court breaker yuav tsum tau siv thaum twg siab nruab nrab tam sim no nyob rau hauv lub Circuit Court.
