Miniature Circuit Breaker yog ib hom kev hloov hluav taws xob rau hluav taws xob qis, siv los tiv thaiv cov khoom siv hluav taws xob thiab kev nyab xeeb ntawm tus kheej.
Cov kab hluav taws xob me me tuaj yeem ntsia tau rau hauv tsev (piv txwv li, hauv cov khoom faib khoom) lossis sab nraum zoov (piv txwv li, hauv cov thawv xa khoom).
1. Muaj peb hom kev teeb tsa: tsau, txawb thiab tshem tawm.
2. Qhov ntsuas tam sim no ntawm Circuit Court breaker muab faib ua N thiab P hom, N yog tam sim no nrog qhov siab tshaj plaws tam sim no, P yog tam sim no nrog qhov tsawg kawg nkaus ntsuas tam sim no, thiab N muab faib ua L, L, N yog 1,2 -3A, thiab B yog 2A raws li qhov ntsuas tam sim no.
Cov hluav taws xob hluav taws xob me me tuaj yeem siv rau hauv thaj chaw, chaw ua haujlwm, chaw ua haujlwm thiab lwm qhov chaw.
I. Kev faib tawm ntawm cov hluav taws xob hluav taws xob me me.
(1) Muab faib los ntawm Arc Extinguishing Medium: Muaj peb lub Arc Extinguishing Systems: Cua, Nqus Tsev lossis Cua-nqus Sib xyaw.
Cov tshuab cua yog tsim rau AC low-voltage tis kab nrog cov ntsuas hluav taws xob mus txog 690V thiab tsis tuaj yeem tiv taus txhua yam kev tsis ua haujlwm luv luv thaum nruab nrab (N) thiab xoom (D) kab sib txuas, vim muaj ntau cov roj inert hauv huab cua.
Tsis tas li ntawd, cov tshuab nrog cov ntsuas hluav taws xob ntawm 690V (N) lossis siab dua (siab dua 1800V) tsis tuaj yeem hla cov kav hlau lossis cov hlau.
Lub tshuab nqus tsev tsim nyog rau cov ntsuas hluav taws xob mus rau 660V, siab load thiab tsis muaj kab hauv av.
(2) Muab faib los ntawm txoj kev ua haujlwm: muaj ob hom: kev tuav haujlwm thiab kev ua haujlwm tsis siv neeg.
Kev khiav hauj lwm phau ntawv: siv los txuas lossis rhuav tshem qhov qub Circuit Court thiab txawv txav, phau ntawv tus neeg siv yog los ntawm phau ntawv hloov, kov lossis khawm kom ua tiav.
Tsis siv neeg ua haujlwm: los ntawm kev hloov hluav taws xob hloov ntawm lub khawm tswj, kom ua tiav cov haujlwm uas yuav tsum tau ua.
(3) Muab faib raws li txoj cai kev ua haujlwm: raws li hom kev sib cuam tshuam ntawm kev sib cuag thiab cov txheej txheem ua haujlwm, lawv tau muab faib ua ob hom;
Ib qho yog mechanical;Lwm qhov yog electrodynamic.
Mechanical Circuit Court breaker feem ntau yog siv rau 50HZ AC, 660V DC, siab dua qhov system.
Electrodynamic nkaus Circuit Court breaker yog siv nyob rau hauv AC 1000V system los yog tsawg voltage tis kab;Lwm hom xws li fuses, reactors, keyboards tuaj yeem tiv thaiv tam sim no thiab tswj.
Electrodynamic nkaus Circuit Court breaker yog muab faib ua cua kis tau tus mob thiab iav kis tau tus mob.
(4) Raws li hom arc extinguishing nruab nrab, muaj peb hom: cua combustion arc extinguishing system, cua arc extinguishing system thiab hluav taws xob inert arc extinguishing chamber composite system.
Inert arc extinguishing systems tuaj yeem muab faib ua ob pawg: nruab nrab kab cais thiab nruab nrab kab sib cais.Cov qub tuaj yeem siv rau hauv nruab nrab circuits rau ntau lub hom phiaj, tom kawg tsis tuaj yeem siv rau hauv txhua txoj kab nruab nrab (xws li chaw nyob thiab chaw ua haujlwm), thiab tom kawg yog siv rau hauv txhua hom hluav taws xob (xws li cov tsev lag luam thiab cov tsev khaws khoom) tsuas yog chaw nyob.
Lub tshuab hluav taws xob arc extinguishing tuaj yeem siv tau rau hauv txhua lub voj voog uas xav tau los tiv thaiv cov kab hluav taws xob los ntawm kev sib tsoo hluav taws xob;Nws tuaj yeem siv tau rau hauv txhua lub voj voog uas xav tau los tiv thaiv kab hluav taws xob los ntawm kev sib tsoo hluav taws xob tsis muaj kev tiv thaiv kev ua haujlwm lossis tsis muaj kev tiv thaiv kev ua haujlwm raws li kev ua haujlwm dav dav.Lub tshuab hluav taws xob hluav taws xob tua hluav taws xob tuaj yeem tsim "luv luv" ntawm lub zog hluav taws xob, lub nra thiab cov kab nruab nrab, uas tuaj yeem txiav tawm qhov txhaum tam sim no sai kom txo qis qhov hluav taws xob ntxiv.
(5) Kev faib tawm los ntawm kev ua haujlwm: muaj unipolar thiab multipolar breakers;ob qho tib si qauv tuaj yeem siv rau hauv cov kab hluav taws xob lossis cov khoom xa tawm, hu ua ib-theem thiab multiphase circuit breakers (uas yog, muaj ob lossis ntau theem) thiab ob-theem Circuit Court breakers (tseem hu ua peb-theem Circuit Court breakers);ib-theem thiab ob-theem Circuit Court breakers muaj lawv tus kheej tshwj xeeb tswj qhov chaw, xws li: peb-theem tam sim no-txheej Circuit Court breakers, thiab lwm yam.;Ob-theem Circuit Court breakers feem ntau yog siv rau hauv kev faib hluav taws xob ntawm 10 kV lossis qis dua, lossis raws li kev tiv thaiv hloov pauv hauv cov khoom xa tawm ntawm 10 kV lossis qis dua.
(6) Muab faib raws li kev siv: muaj cov ntsuas me me thiab loj dua tam sim no;
