Circuit Court breakers yog tsim nyob rau hauv ntau yam kev ntsuas tam sim no, los ntawm cov khoom siv uas tiv thaiv cov hluav taws xob qis tam sim no lossis cov khoom siv hauv tsev ib leeg, mus rau cov khoom siv hluav taws xob tsim los tiv thaiv cov hluav taws xob hluav taws xob ntau hauv lub nroog.
Liperua rau Miniature Circuit Breaker (MCB) - ntsuas tam sim no mus txog 63 A, uas feem ntau siv rau hauv tsev, kev lag luam, kev lag luam teeb pom kev zoo.
MCBs feem ntau tsis raug rhuav tshem thaum dhau tam sim no yog li lawv rov siv tau. Lawv kuj tseem siv tau yooj yim dua, muab qhov yooj yim ntawm 'on / off switching' rau kev sib cais ntawm Circuit Court thiab txij li tus neeg xyuas pib nyob hauv lub hnab yas, lawv muaj kev nyab xeeb dua rau kev siv thiab ua haujlwm.
MCB muajPeb lub hauv paus ntsiab lus, Amperes, Kilo Amperes thiab Tripping Curve
Overload tam sim no ntsuas - Amperes (A)
Overload tshwm sim thaum cov khoom siv ntau dhau tau muab tso rau hauv ib lub voj voog thiab kos cov hluav taws xob ntau dua li qhov Circuit Court thiab cable yog tsim los coj. Qhov no tuaj yeem tshwm sim hauv chav ua noj, piv txwv li thaum lub rhaub dej, lub tshuab ntxhua khaub ncaws, hluav taws xob qhov cub, microwave thiab rab chais siv ib txhij. MCB ntawm no Circuit Court txiav fais fab yog li tiv thaiv overheating thiab hluav taws nyob rau hauv lub cable thiab terminals.
Qee cov qauv:
6 amp ua- txheem teeb pom kev zoo circuits
10 amp- loj teeb pom kev zoo circuits
16 Amp thiab 20 Amp- Cov cua sov thiab boilers
32 amp ua- Nplhaib kawg. Lub sij hawm technical rau koj lub hwj huam hluav taws xob lossis lub qhov (sockets). Piv txwv ib lub tsev ob chav pw tej zaum yuav muaj 2 x 32A fais fab hluav taws xob los cais cov qhov rooj sab saud thiab hauv qab. Cov tsev loj dua tuaj yeem muaj tus lej ntawm 32 A circuits.
40 amp- Cookers / hluav taws xob hobs / me da dej
50 amp- 10kw Electric da dej / Kub tubs.
63amp ua- tag nrho lub tsev
Liper Breakers npog qhov ntau ntawm 1A txog 63A
Kev ntsuas luv luv - Kilo Amperes (kA)
Short Circuit yog qhov tshwm sim ntawm qhov ua txhaum ntawm qhov chaw hauv hluav taws xob lossis cov khoom siv hluav taws xob thiab muaj peev xwm txaus ntshai ntau dua li kev tshaj tawm.
MCBs siv rau hauvdomestic installationsfeem ntau yog nyob ntawm6k ualos yog 6000 amps. Kev sib raug zoo ntawm ib txwm muaj hluav taws xob (240V) thiab cov khoom siv hluav taws xob siv hluav taws xob zoo ib yam txhais tau hais tias qhov dhau-tam sim no tshwm sim los ntawm luv luv Circuit Court yuav tsum tsis pub tshaj 6000 amps. Txawm li cas los xij, hauvkev lag luam thiab kev lag luam, thaum siv 415V thiab cov tshuab loj, nws yog qhov yuav tsum tau siv10 kArated MCBs.
Tripping Curve
Lub 'Tripping Curve' ntawm MCB tso cai rau lub ntiaj teb tiag tiag thiab qee zaum tsim nyog, nce lub zog. Piv txwv li, nyob rau hauv ib puag ncig kev lag luam, cov tshuab loj feem ntau yuav tsum muaj lub zog pib ntawm lub zog ntau dhau ntawm lawv cov kev khiav hauj lwm tam sim no kom kov yeej cov inertia ntawm cov motors loj. Qhov kev nce siab luv luv no tsuas yog ob peb feeb xwb, tau tso cai los ntawm MCB vim nws muaj kev nyab xeeb hauv lub sijhawm luv luv.
MuajPeb txoj cai Curve Typesuas tso cai rau surges nyob rau hauv txawv hluav taws xob ib puag ncig:
Hom B MCBsyog siv rau hauvkev tiv thaiv hluav taws xob hauv tsevqhov twg muaj me ntsis xav tau kev tso cai surge. Ib qho kev nce siab loj hauv ib puag ncig hauv tsev yuav yog qhov tshwm sim ntawm qhov ua txhaum, yog li qhov ntau tshaj qhov tso cai tam sim no kuj tsawg.
Hom C MCBskev mus ncig ntawm 5 thiab 10 zaug puv load tam sim no thiab siv rau hauvcoj mus muag thiab lub teeb industrial ib puag nciguas tej zaum yuav muaj cov teeb pom kev zoo fluorescent loj, transformers thiab IT khoom xws li servers, PCs thiab printers.
Hom D MCBsyog siv rau hauvhnyav industrial chawxws li cov chaw tsim khoom siv loj winding motors, X-ray tshuab lossis compressors.
Tag nrho peb hom MCBs muab kev tiv thaiv tripping hauv ib feem kaum ntawm ib thib ob. Qhov ntawd yog hais tias, thaum lub sijhawm dhau los thiab lub sijhawm dhau mus, MCB mus ncig hauv 0.1 vib nas this.
Yog li ntawd, Liper ib txwm ua tau raws li koj xav tau.
