Lub Circuit Court breaker: tuaj yeem hloov mus rau, nqa thiab rhuav tshem tam sim no raws li qhov xwm txheej hauv Circuit Court, kuj tuaj yeem hloov mus rau hauv cov xwm txheej tsis zoo li qub, nqa ib lub sijhawm thiab rhuav tshem tam sim no ntawm lub tshuab hluav taws xob.
Micro Circuit Breaker, hu ua MCB (Micro Circuit Breaker), yog qhov dav siv dav dav siv hluav taws xob tiv thaiv cov khoom siv hluav taws xob hauv kev tsim hluav taws xob cov khoom siv hluav taws xob.Nws yog siv rau ib-theem thiab peb-theem luv luv Circuit Court, overload thiab overvoltage tiv thaiv hauv qab 125A, suav nrog plaub yam ntawm ib tug ncej 1P, ob-ncej 2P, peb-ncej 3P thiab plaub-ncej 4P.
Lub micro circuit breaker muaj cov txheej txheem kev khiav hauj lwm, kev sib cuag, cov cuab yeej tiv thaiv (ntau yam khoom tso tawm), arc extinguishing system, thiab lwm yam. Lub ntsiab tiv tauj yog manually ua los yog hluav taws xob kaw.Tom qab qhov kev sib cuag tseem ceeb raug kaw, qhov kev mus ncig dawb mechanism kaw qhov kev sib cuag tseem ceeb hauv txoj haujlwm kaw.Lub kauj ntawm lub overcurrent tso tawm thiab lub thermal caij ntawm lub thermal tso tawm yog txuas nrog lub ntsiab Circuit Court nyob rau hauv series, thiab lub kauj ntawm lub undervoltage tso tawm yog txuas nrog lub hwj chim mov nyob rau hauv parallel.Thaum lub Circuit Court tshwm sim luv luv los yog overload loj, lub armature ntawm lub overcurrent mus txawv tebchaws ntaus ntawv draws, ua lub free mus txawv tebchaws mechanism, thiab lub ntsiab tiv tauj disconnects lub ntsiab Circuit Court.Thaum lub Circuit Court yog overloaded, lub tshav kub ntawm lub thermal mus txawv tebchaws ntaus ntawv heats mus rau khoov daim ntawv bimetal thiab thawb lub free mus txawv tebchaws mechanism ua.Thaum lub Circuit Court nyob rau hauv voltage, lub armature ntawm lub undervoltage releaser yog tso tawm.Kuj tseem tso cai rau kev mus ncig dawb mechanism ua haujlwm.
Qhov seem tam sim no Circuit Court-breaker: Ib qho kev hloov pauv uas tau ua haujlwm thaum qhov seem tam sim no hauv Circuit Court tshaj tus nqi preset.Feem ntau siv cov hluav taws xob hluav taws xob hluav taws xob tau muab faib ua ob pawg: hom hluav taws xob thiab hom tam sim no, thiab hom tam sim no muab faib ua hom hluav taws xob thiab hluav taws xob.Cov hluav taws xob hluav taws xob hluav taws xob yog siv los tiv thaiv tus kheej poob siab, thiab yuav tsum tau xaiv raws li qhov sib txawv ntawm kev sib cuag ncaj qha thiab tiv thaiv kev tiv thaiv tsis ncaj.
Xaiv raws li lub hom phiaj ntawm kev siv thiab qhov chaw uas cov khoom siv hluav taws xob nyob
1) Kev tiv thaiv los ntawm kev sib cuag ncaj qha nrog hluav taws xob poob siab
Vim tias qhov kev puas tsuaj ntawm kev sib cuag hluav taws xob ncaj qha yog qhov loj, qhov tshwm sim yog qhov loj heev, yog li xaiv qhov hluav taws xob hluav taws xob hluav taws xob nrog lub siab rhiab heev, rau cov cuab yeej hluav taws xob, cov khoom siv hluav taws xob txawb thiab cov kab ib ntus, yuav tsum tau muab tso rau hauv lub voj voog ua haujlwm tam sim no ntawm 30mA, Lub sijhawm ua haujlwm hauv 0.1s to Circuit Court breaker.Rau cov tsev nyob nrog ntau cov khoom siv hauv tsev, nws yog qhov zoo tshaj rau nruab nws tom qab nkag mus rau hauv lub ntsuas hluav taws xob hauv tsev.
Yog tias ib zaug hluav taws xob poob siab yog ib qho yooj yim ua rau muaj kev puas tsuaj rau theem nrab (xws li ua haujlwm ntawm qhov siab), lub qhov hluav taws xob hluav taws xob hluav taws xob nrog kev ua haujlwm tam sim no ntawm 15mA thiab lub sijhawm ua haujlwm hauv Teb Chaws Asmeskas yuav tsum tau muab tso rau hauv lub voj voog.Rau cov khoom siv kho mob hluav taws xob hauv tsev kho mob, cov hluav taws xob hluav taws xob hluav taws xob nrog kev ua haujlwm tam sim no ntawm 6mA thiab lub sijhawm ua haujlwm hauv Asmeskas yuav tsum tau teeb tsa.
2) Indirect tiv thaiv
Indirect contact hluav taws xob poob siab nyob rau hauv ntau qhov chaw yuav ua rau txawv degrees ntawm kev puas tsuaj rau tus neeg, yog li sib txawv toggle Circuit Court breakers yuav tsum tau ntsia nyob rau hauv ntau qhov chaw.Nws yuav tsum tau siv cov hluav taws xob hluav taws xob hluav taws xob uas muaj qhov siab tshaj plaws rau qhov chaw uas hluav taws xob poob siab dua.Hauv qhov chaw ntub dej ntau dua li qhov chaw qhuav qhov kev pheej hmoo ntawm hluav taws xob poob siab ntau dua, feem ntau yuav tsum tau teeb tsa kev khiav hauj lwm tam sim no ntawm 15-30mA, lub sijhawm ua haujlwm hauv 0.1s to Circuit Court breaker.Rau cov khoom siv hluav taws xob hauv dej, kev nqis tes ua yuav tsum tau teeb tsa.Cov hluav taws xob hluav taws xob tawg nrog tam sim no ntawm 6-l0mA thiab lub sijhawm ua haujlwm hauv Asmeskas.Rau cov khoom siv hluav taws xob uas tus neeg teb xov tooj yuav tsum tau sawv ntawm cov khoom siv hlau lossis hauv lub thawv hlau, tsuav yog qhov hluav taws xob siab dua 24V, qhov hluav taws xob hluav taws xob hluav taws xob uas muaj kev khiav hauj lwm tam sim no qis dua 15mA thiab lub sijhawm ua haujlwm hauv Teb Chaws Asmeskas yuav tsum tau nruab.Rau cov khoom siv hluav taws xob ruaj khov nrog qhov hluav taws xob ntawm 220V lossis 380V, thaum qhov av tsis kam ntawm lub tsev nyob qis dua 500fZ, ib lub tshuab tuaj yeem nruab qhov hluav taws xob hluav taws xob hluav taws xob nrog kev ua haujlwm tam sim no ntawm 30mA thiab lub sijhawm ua haujlwm ntawm 0.19.Rau cov khoom siv hluav taws xob loj uas muaj qhov ntsuas tam sim no ntau dua 100A lossis lub zog hluav taws xob hluav taws xob nrog ntau yam khoom siv hluav taws xob, cov hluav taws xob hluav taws xob hluav taws xob tuaj yeem nruab nrog kev khiav hauj lwm tam sim no ntawm 50-100mA.Thaum cov av tsis kam ntawm cov khoom siv hluav taws xob qis dua 1000, lub tshuab hluav taws xob xaim hluav taws xob nrog kev ua haujlwm tam sim no ntawm 200-500mA tuaj yeem ntsia tau.
