Qhov txawv ntawm DC fuse Holder thiab Miniature Circuit Breaker

CovDC fuse tuavfeem ntau yog ntsia rau hauv Circuit Court thiab siv los xyuas kom meej qhov kev nyab xeeb ntawm Circuit Court thaum lub sij hawm ua hauj lwm ntawm ib qho tseem ceeb hluav taws xob tivthaiv.DC fuses yog cov khoom tiv thaiv uas tuaj yeem muab kev tiv thaiv luv luv, thiab tau siv dav hauv cov tshuab hluav taws xob, kev tswj hwm, thiab lwm yam. Lub fuse feem ntau ua lub luag haujlwm hauv kev tiv thaiv luv luv thiab kev tiv thaiv hnyav dhau.

Feem ntau,DC me me Circuit Court breakerstuaj yeem siv los faib hluav taws xob hluav taws xob lossis pib asynchronous motors infrequently, thiab tseem tiv thaiv cov kab hluav taws xob thiab cov motors.Yog hais tias lub DC Circuit Court breaker ntsib ib tug loj overload, luv luv Circuit Court, los yog undervoltage txhaum thaum lub sij hawm ua hauj lwm, nws yuav txiav tawm Circuit Court.Kev ua haujlwm ntawm Circuit Court breaker zoo ib yam li kev sib txuas ntawm fuse hloov thiab overheating relay.

Lub ntsiab lus ntawm DC fuse thiab mini Circuit Court breaker: nws tuaj yeem txiav tawm lub voj voog kom zoo thaum lub voj voog tsis ua haujlwm, yog li nws tuaj yeem hais tias ob qho tib si yog cov khoom siv tiv thaiv hluav taws xob, feem ntau yog siv los tiv thaiv Circuit Court breaker ntawm overload thiab luv luv Circuit Court.

Lub luag haujlwm ntawm DC Fuse Holder thiab Mini Circuit Breaker yog dab tsi?

Cov ciam teb ntawm DC mini Circuit Court breakers yog fuzzy.Cov kev siv feem ntau muab faib ua high-voltage circuit breakers thiab low-voltage circuit breakers.Feem ntau, peb feem ntau hu cov voltages saum 3KV li high-voltage circuit breakers, thiab low-voltage circuit breakers kuj hu ua tsis siv neeg keyboards.Nws yog ib qho khoom siv hluav taws xob uas tsis yog tsuas yog muaj kev hloov pauv hauv phau ntawv xwb, tab sis kuj muaj cov khoom siv tiv thaiv tsis siv neeg rau kev poob ntawm qhov hluav taws xob, tsis muaj hluav taws xob, overload thiab luv-circuit.DC Circuit Court breakers kuj tau muab faib ua universal circuit breakers thiab molded case circuit breakers.Feem ntau, tsis tas yuav hloov qhov chaw thiab cov khoom siv tom qab qhov txhaum tam sim no tawg, thiab lawv tau siv dav.

Thaum lub DC fuse tuav yog ib qho kev tiv thaiv tam sim no uas tiv thaiv cov khoom siv hluav taws xob los ntawm qhov tam sim no.Tom qab qhov tam sim no tshaj li tus nqi teev tseg rau ib lub sijhawm, cov cua sov tsim los ntawm lub fuse nws tus kheej txhawb cov yaj ntawm cov yaj, yog li rhuav tshem lub voj voog.DC fuses feem ntau yog siv dav hauv cov tshuab hluav taws xob qis hluav taws xob thiab kev tswj hwm thiab cov khoom siv hluav taws xob.Raws li kev tiv thaiv luv luv thiab dhau tam sim no, lawv yog ib qho ntawm cov khoom siv tiv thaiv feem ntau siv.

Yog li, DC Circuit Court breaker tuaj yeem hloov lub fuse, tsuav yog qhov ntsuas kev ua haujlwm tam sim no ntawm lub fuse thiab Circuit Court breaker yog tib yam li qhov ntsuas tam sim no.Tab sis yog tias lub Circuit Court breaker siv los ua lub fuse, puas yog me ntsis overkill?

Qhov txawv ntawm DC fuse Holder thiab Mini Circuit Breaker yog dab tsi?

Qhov zoo sib xws ntawm DC fuse tuav thiab Circuit Court breakers yog tias lawv tuaj yeem paub txog kev tiv thaiv luv luv.Lub hauv paus ntsiab lus ntawm fuse yog: siv tam sim no ntws los ntawm tus neeg xyuas pib yuav ua kom sov tus neeg xyuas pib, tom qab ncav cuag lub melting point ntawm tus neeg xyuas pib, tus neeg xyuas pib yuav yaj.Yog li ntawd, lub Circuit Court tuaj yeem raug txiav tawm los tiv thaiv cov khoom siv hluav taws xob thiab cov kab hluav taws xob kom tsis txhob raug hlawv.Nws yog ib qho tsub zuj zuj ntawm cov cua sov, yog li kev tiv thaiv overload kuj tuaj yeem pom tau, thaum lub yaj raug hlawv, cov yaj yuav tsum tau hloov.Thaum cov hluav taws xob thauj khoom hauv Circuit Court yog nyob ze rau lub load ntawm lub fuse siv ntev, lub fuse yuav tsum tau rhuab maj mam kom txog thaum nws yog fused.Qhov kev sib txuas ntawm fuse yog qhov tshwm sim ntawm kev sib koom ua ke ntawm tam sim no thiab lub sijhawm, uas ua lub luag haujlwm ntawm kev tiv thaiv kab.Nws yog pov tseg.

DC Circuit Court breaker kuj tseem tuaj yeem paub qhov luv luv thiab kev tiv thaiv kev tiv thaiv ntawm kab, tab sis lub hauv paus ntsiab lus txawv.Nws paub txog kev tiv thaiv Circuit Court breaker los ntawm qhov tam sim no hauv qab magnetic nyhuv (electromagnetic tripper), thiab paub txog kev tiv thaiv overload los ntawm thermal nyhuv ntawm tam sim no.Thaum tam sim no nyob rau hauv Circuit Court dheev nce thiab tshaj lub load ntawm lub Circuit Court breaker, lub Circuit Court breaker yuav cia li qhib.Nws yog kev tiv thaiv kom nce qhov tam sim no tam sim no ntawm Circuit Court, xws li thaum lub xau loj, luv luv Circuit Court, lossis tam sim no tam sim no loj.Tom qab pom qhov ua rau pom, nws tuaj yeem hloov mus thiab siv txuas ntxiv mus.

Txawm hais tias qhov kev ua haujlwm thiab kev ua haujlwm ntawm DC Circuit Court breaker thiab lub fuse yog tib yam, tseem muaj ntau qhov sib txawv, xws li qhov sib txawv ntawm kev tiv thaiv, kev khiav hauj lwm ceev, lub sij hawm siv, thiab cov qauv kev ua haujlwm.Qhov sib txawv ntawm fuse thiab Circuit Court breaker yog raws li nram no:

1. Qhov txawv ntawm txoj kev tiv thaiv: DC fuse tuav tiv thaiv txoj kev txais yuav daim ntawv fuse.Tom qab qhov tshwm sim txhaum raug tshem tawm, lub fuse yuav tsum tau hloov kho kom rov qab siv lub zog, yog li nws tsis yooj yim rau kev tswj xyuas.Txoj kev tiv thaiv ntawm DC Circuit Court breaker txais daim ntawv tripping.Tom qab tshem tawm qhov txhaum, cov khoom siv hluav taws xob ib txwm tuaj yeem rov qab los ntawm kev ua haujlwm kaw nkaus xwb, yog li kev saib xyuas thiab kho dua tshiab yuav yooj yim dua li lub fuse.

2. Qhov sib txawv ntawm qhov kev ua haujlwm ceev: lub fuse ua haujlwm ceev ntawm DC fuse tuaj yeem ncav cuag qib microsecond (μs), uas txhais tau hais tias nws qhov nrawm nrawm dua li ntawm lub Circuit Court breaker.Qhov peev xwm no feem ntau yog tsim nyog rau kev txiav tawm sai sai Kev teeb tsa thiab siv raws li qhov xwm txheej.Lub tripping ceev ntawm Circuit Court breaker yog nyob rau hauv milliseconds (ms).Nws tuaj yeem pom tias nws qeeb dua li lub fuse, yog li nws tsuas yog tsim nyog rau lub sijhawm uas qhov kev txiav ceev tsis siab heev.

3. Qhov sib txawv ntawm cov sij hawm siv: DC fuse yuav tsum tau hloov tom qab kev tiv thaiv kev ua txhaum ib zaug thiab cov yaj tau tawg, thiab DC Circuit Court breaker tuaj yeem rov qab siv tau ntau zaus.Txawm li cas los xij, los ntawm qhov pom ntawm qhov cuam tshuam ntawm Circuit Court breaker, lub fuse yuav muaj zog dua li ntawm Circuit Court breaker, thiab tib lub sijhawm ntau dua.Nyob rau hauv ib txwm muaj xwm txheej, lub Circuit Court breaker yog ntsia rau ntawm ceg txoj kev, thiab lub fuse yog ntsia rau ntawm txoj kev loj nyob rau hauv feem ntau yog ua si lub luag hauj lwm ntawm lwm yam kev tiv thaiv.

4. Qhov sib txawv ntawm kev ua hauj lwm hauv paus ntsiab lus: Lub hauv paus ntsiab lus ua haujlwm ntawm DC fuse feem ntau yog raws li cov thermal nyhuv ntawm cov tam sim no.Thaum qhov tam sim no tshaj tus nqi ruaj khov (qhov sib txawv ntawm cov fuse kuj sib txawv), lub fuse sab hauv yuav ua rau lub voj voog tawg thiab tiv thaiv Cov khoom siv tsis raug kub hnyiab los ntawm cov tam sim no siab.Thaum muaj ntau hom DC Circuit Court breakers thiab lawv cov qauv tsim kuj txawv.Feem ntau, qhov kev mus ncig ntawm lub coil excitation yog tshwm sim los ntawm qhov tam sim no ntau dhau los ua rau lub Circuit Court breaker ua qhov kev txiav txim tripping.Ntawm chav kawm, lub Circuit Court breaker tuaj yeem tsis tsuas yog ua tiav kev ua haujlwm tsis siv neeg, tab sis kuj Manually tswj qhov qhib thiab kaw cov haujlwm ntawm Circuit Court breaker.

Hauv qee lub sijhawm tshwj xeeb, muaj cov kev cai tshwj xeeb uas yuav tsum tau siv DC fuses, xws li kev tiv thaiv of elevator, yog li DC Circuit Court breakers tsis tuaj yeem hloov cov fuses.Ntxiv mus, lub sij hawm luv luv ntawm Circuit Court breaker's thyristor module yog luv heev.Nyob rau hauv cov ntaub ntawv no, lub tripping ceev ntawm lub Circuit Court breaker tsis tau raws li lub luv luv-circuit yuav tsum tau, yog li lub fusing muaj peev xwm ntawm lub fuse kuj tau lees paub.Lub DC fuse tau siv dav hauv kev tsim cov pib muag muag, kev hloov pauv zaus thiab lwm yam kev faib khoom.
