Cov cuab yeej hluav taws xob raug tsim los ntawm ntau qhov ntsuas tam sim no, los ntawm cov khoom siv uas tiv thaiv cov hluav taws xob qis lossis cov khoom siv hauv tsev, mus rau cov switchgear tsim los tiv thaiv cov hluav taws xob siab uas pub rau tag nrho lub nroog.
Liperua Miniature circuit breaker (MCB) - ntsuas tam sim no txog li 63 A, uas feem ntau siv rau hauv tsev, kev lag luam, teeb pom kev zoo hauv kev lag luam.
Feem ntau cov MCBs tsis raug rhuav tshem thaum muaj hluav taws xob ntau dhau yog li lawv siv tau dua. Lawv kuj yooj yim dua rau siv, muab qhov yooj yim ntawm 'kev hloov pauv / kaw' rau kev cais tawm ntawm lub voj voog thiab vim tias tus neeg coj hluav taws xob nyob hauv lub thawv yas, lawv muaj kev nyab xeeb dua rau kev siv thiab ua haujlwm.
Ib lub MCB muajpeb yam ntxwv tseem ceeb, Amperes, Kilo Amperes thiab Tripping Curve
Kev Ntsuas Tam Sim No Overload - Amperes (A)
Kev siv hluav taws xob ntau dhau tshwm sim thaum muab ntau yam khoom siv hluav taws xob tso rau hauv ib lub voj voog thiab rub hluav taws xob ntau dua li lub voj voog thiab cov xov hlau tsim los siv. Qhov no tuaj yeem tshwm sim hauv chav ua noj, piv txwv li thaum lub lauj kaub dej, lub tshuab ntxuav tais diav, lub qhov cub hluav taws xob, lub tshuab ua kom sov thiab lub tshuab sib tov siv tib lub sijhawm. Lub MCB ntawm lub voj voog no txiav hluav taws xob yog li tiv thaiv kev kub dhau thiab hluav taws kub hauv cov xov hlau thiab cov terminals.
Qee cov qauv:
6 Amp- cov voj voog teeb pom kev zoo txheem
10 Amp- cov voj voog teeb pom kev loj
16 Amp thiab 20 Amp- Cov cua sov thiab boilers
32 Amp- Lub Nplhaib Kawg. Lo lus siv rau koj lub voj voog fais fab lossis cov qhov (sockets). Piv txwv li, ib lub tsev ob chav pw yuav muaj 2 lub voj voog fais fab x 32A los cais cov qhov (sockets) sab saud thiab sab hauv qab. Cov tsev loj dua tuaj yeem muaj ntau lub voj voog 32 A.
40 Amp- Cov qhov cub ua noj / cov qhov cub hluav taws xob / cov chav da dej me me
50 Amp- 10kw Cov da dej hluav taws xob / Cov dab dej kub.
63 Amp- tag nrho lub tsev
Cov Liper Breakers npog ntau yam ntawm 1A txog 63A
Kev Ntsuas Luv Circuit Court - Kilo Amperes (kA)
Qhov luv luv ntawm lub voj voog hluav taws xob yog qhov tshwm sim ntawm qhov ua yuam kev hauv lub voj voog hluav taws xob lossis cov khoom siv thiab muaj peev xwm ua rau muaj kev phom sij ntau dua li kev thauj khoom ntau dhau.
MCBs siv rau hauvkev teeb tsa hauv tsevfeem ntau yog ntsuas ntawm6kAlossis 6000 amps. Kev sib raug zoo ntawm qhov hluav taws xob ib txwm muaj (240V) thiab cov ntsuas hluav taws xob hauv tsev ib txwm txhais tau tias qhov hluav taws xob ntau dhau los ntawm kev luv luv yuav tsum tsis pub tshaj 6000 amps. Txawm li cas los xij, hauvcov xwm txheej kev lag luam thiab kev lag luam, thaum siv 415V thiab cov tshuab loj, nws yog qhov tsim nyog los siv10kAcov MCBs uas tau ntsuas.
Kev Tawm Tsam Nkhaus
Qhov 'Tripping Curve' ntawm MCB tso cai rau lub ntiaj teb tiag tiag thiab qee zaum tsim nyog kiag li, nce zog. Piv txwv li, cov chaw ua lag luam hauv tsev so, cov tshuab loj feem ntau xav tau kev nce zog thawj zaug ntau dua li lawv cov hluav taws xob khiav ib txwm kom kov yeej qhov inertia ntawm cov cav loj. Qhov kev nce zog luv luv no kav ntev li ob peb feeb xwb, MCB tso cai vim nws muaj kev nyab xeeb hauv lub sijhawm luv luv.
Muaj covpeb hom nkhaus tseem ceebuas tso cai rau cov surges hauv ntau qhov chaw hluav taws xob sib txawv:
Hom B MCBssiv rau hauvkev tiv thaiv hluav taws xob hauv tsevqhov twg tsis tas yuav tsum tau kev tso cai rau kev siv hluav taws xob ntau dhau. Txhua qhov kev siv hluav taws xob ntau dhau hauv ib puag ncig hauv tsev yuav yog qhov tshwm sim ntawm qhov txhaum, yog li qhov ntau ntawm cov hluav taws xob ntau dhau uas raug tso cai yog qhov me me.
Hom C MCBskev mus ncig ntawm 5 thiab 10 zaug tam sim no puv nkaus thiab siv rau hauvchaw ua lag luam thiab chaw lag luam meuas tej zaum yuav muaj cov voj voog teeb pom kev zoo fluorescent loj, cov transformers thiab cov khoom siv IT xws li cov servers, PCs thiab cov tshuab luam ntawv.
Hom D MCBssiv rau hauvcov chaw ua lag luam hnyavxws li cov chaw tsim khoom siv cov cav loj loj, cov tshuab X-ray lossis cov compressors.
Tag nrho peb hom MCB muab kev tiv thaiv kev tawg hauv ib feem kaum ntawm ib pliag. Uas yog hais tias, thaum lub sijhawm overload thiab lub sijhawm tau dhau lawm, MCB tawg hauv 0.1 vib nas this.
Yog li ntawd, Liper ib txwm ua tau raws li koj xav tau.
