Vim li cas MCBs mus ncig ntau zaus? Yuav ua li cas kom tsis txhob MCB tripping?

Cov teeb meem hluav taws xob tuaj yeem cuam tshuam ntau lub neej vim yog overloads lossis luv luv Circuit Court, thiab tiv thaiv los ntawm overloads & luv Circuit Court, MCB yog siv.Miniature Circuit Breakers(MCBs) yog cov khoom siv hluav taws xob uas siv los tiv thaiv hluav taws xob hluav taws xob los ntawm Overload & Short Circuit. Lub ntsiab yog vim li cas rau ib tug overcurrent yuav yog ib tug luv luv Circuit Court, overload los yog txawm ib tug faulty tsim. Thiab ntawm no hauv blog no, peb yuav qhia koj txog qhov laj thawj rau MCB tripping nquag thiab txoj hauv kev kom zam dhau. Ntawm no, saib!

Qhov zoo ntawm MCB:

● Cov hluav taws xob hluav taws xob tau txiav tawm thaum muaj qhov txawv txav ntawm lub network tshwm sim

● Lub faulty cheeb tsam ntawm cov hluav taws xob Circuit Court tau yooj yim raug txheeb xyuas, raws li cov kev khiav hauj lwm pob qhov rooj tau tawm txoj hauj lwm thaum tripping

● Kev kho sai sai ntawm cov khoom siv yog ua tau thaum MCB

● MCB muaj hluav taws xob zoo dua li lub fuse

Yam ntxwv:

● Tus nqi tam sim no tsis tshaj 100A

● Cov yam ntxwv ntawm kev mus ncig yog ib txwm tsis kho

● Thermal thiab sib nqus ua haujlwm

Nta thiab cov txiaj ntsig ntawm MCB

1. Kev tiv thaiv kev poob siab thiab hluav taws kub:

Ua ntej thiab qhov tseem ceeb tshaj plaws ntawm MCB yog tias nws pab tshem tawm kev sib cuag tsis raug. Nws yog ua haujlwm thiab tswj tsis muaj teeb meem.

2. Anti welding contacts:

Vim nws cov cuab yeej los tiv thaiv vuam, nws ua kom lub neej zoo dua thiab muaj kev nyab xeeb dua.

3. Kev nyab xeeb davhlau ya nyob twg los yog captive screws:

Lub thawv hom davhlau ya nyob twg tsim muab kev txiav kom raug thiab tsis txhob xoob kev sib txuas.

Yog vim li cas vim li cas MCBs mus ncig ntau zaus

Muaj 3 qhov laj thawj ntawm MCBs tripping nquag:

1. Tshaj dhau Circuit Court

Circuit Court overloading yog paub tias yog vim li cas feem ntau rau Circuit Court breaker tripping. Nws tsuas yog txhais tau tias peb tab tom khiav ntau lub zog siv hluav taws xob hnyav tib lub sijhawm ntawm tib lub voj voog.

2. luv Circuit Court

Qhov laj thawj txaus ntshai tshaj plaws yog qhov luv luv. Lub voj voog luv luv tshwm sim thaum lub xaim / theem kov lwm lub xaim / theem lossis kov lub "nruab nrab" xaim hauv Circuit Court. Lub siab tam sim no ntws thaum ob lub xov hlau no kov tsim cov dej ntws hnyav, ntau tshaj li qhov Circuit Court tuaj yeem ua tau.

3. Av txhaum

Ib qho txhaum hauv av yuav luag zoo ib yam li qhov luv luv. Cov ntaub ntawv no tshwm sim thaum lub xov hlau kub kov cov xaim hauv av.

Qhov tseem ceeb, peb tuaj yeem hais tias lub sijhawm thaum lub voj voog tawg, nws txhais tau hais tias tam sim no dhau ntawm AMPs uas koj lub cev tsis tuaj yeem ua haujlwm, piv txwv li lub kaw lus yog overloaded.

Breakers yog cov cuab yeej kev nyab xeeb. Nws yog tsim los tiv thaiv tsis yog cov cuab yeej siv xwb tab sis cov xaim thiab lub tsev thiab. Yog li, thaum MCB mus ncig ua si, muaj qhov laj thawj thiab qhov ntsuas no yuav tsum tau ua tiag tiag. Thiab thaum koj rov pib dua MCB, thiab nws tam sim ntawd rov qab mus dua, ces nws feem ntau qhia tau hais tias luv luv.

Lwm qhov laj thawj rau lub breaker mus txawv tebchaws yog xoob hluav taws xob sib txuas thiab tuaj yeem kho tau yooj yim los ntawm kev zawm lawv.

Qee cov lus qhia tseem ceeb kom tsis txhob MCBs tripping

● Peb yuav tsum tshem tawm tag nrho cov khoom siv thaum nws tsis siv

● Peb yuav tsum paub tias muaj pes tsawg cov khoom siv ntsaws rau hauv lub sijhawm kub lossis txias

● Yuav tsum xyuas kom meej tias tsis muaj ib qho ntawm koj cov khoom siv hluav taws xob puas lossis tawg

● Tsis txhob siv cov hlua txuas ntxiv thiab cov hlua fais fab yog tias koj muaj ob peb lub qhov hluav taws xob

Short circuits

Circuit breaker mus ncig ua si tshwm sim thaum twg koj lub tshuab hluav taws xob lossis ib qho ntawm cov ntawv thov uas koj siv tau luv. Hauv qee lub tsev, nws nyuaj rau txheeb xyuas qhov luv luv nyob qhov twg. Thiab txhawm rau txheeb xyuas luv luv hauv ib qho khoom siv, siv cov txheej txheem tshem tawm. Tig lub hwj chim thiab ntsaws txhua lub cuab yeej ib qho los ntawm ib qho. Saib seb cov khoom siv tshwj xeeb puas ua rau muaj kev tawg.

Yog li, qhov no yog vim li cas MCB mus ncig ntau zaus thiab txoj hauv kev kom tsis txhob MCB tripping.
