Kev nyab xeeb hluav taws xob yuav tsum tau siv hauv cov khoom siv hauv Circuit Court - lub tshuab hluav taws xob. Lub tshuab hluav taws xob hluav taws xob tau muab faib ua hluav taws xob hluav taws xob hluav taws xob hluav taws xob thiab hluav taws xob hluav taws xob hluav taws xob qis, ob qho kev siv sib txawv, cov tshuab hluav taws xob hluav taws xob niaj hnub no muab rau koj ntau hom kev siab thiab qis hluav taws xob hluav taws xob hluav taws xob thiab qhov sib txawv.
High voltage Circuit Court breaker
1, qhov hluav taws xob hluav taws xob muaj hluav taws xob ntau (QF) - luv Circuit Court, tua hluav taws, ua haujlwm ib txwm muaj
Cov hluav taws xob hluav taws xob hluav taws xob muaj cov cuab yeej txhim khu kev qha, uas muaj peev xwm ua kom muaj zog. Thaum lub Circuit ua haujlwm, nws tuaj yeem siv los hloov lossis txiav tawm qhov thauj khoom tam sim no. Thaum lub Circuit Court tsis raug, nws tuaj yeem tiv thaiv qhov xwm txheej los ntawm kev nthuav dav thiab ua kom muaj kev nyab xeeb kev ua haujlwm. Tseem tuaj yeem siv los txiav tawm luv luv luv tam sim no. Cov hluav taws xob hluav taws xob hluav taws xob siab kom qhib 1500V, tam sim no ntawm 1500-2000A arc, txoj kab hluav taws xob tuaj yeem rub mus rau 2m tseem txuas ntxiv mus rau qhov hluav taws kub tsis tua. Yog li ntawd, kev tua hluav taws yog ib qho teeb meem uas cov hluav taws xob hluav taws xob hluav taws xob loj yuav tsum daws.
Cov hluav taws xob hluav taws xob hluav taws xob siab raws li qhov sib txawv ntawm qhov nruab nrab tua hluav taws tuaj yeem muab faib ua cov roj ntau hluav taws xob tua hluav taws xob hluav taws xob, cov roj hluav taws xob qis hluav taws xob, hluav taws xob hluav taws xob hluav taws xob tawg, lub tshuab nqus tsev nqus hluav taws xob, cov pa hluav taws xob hexafluoride Circuit Court breaker, sib nqus tshuab hluav taws xob tawg, thiab lwm yam.
Ntau hom kev tiv thaiv hluav taws xob qis
1, cov kab hluav taws xob tawg (thoob ntiaj teb) - ACB
Hauv qhov ntsuas tam sim no, hauv txoj cai ntsuas tam sim no 630A lub plawv xav tau kev siv lub tshuab hluav taws xob tawg, cov ntaub ntawv hluav taws xob Circuit Court breaker feem ntau yog 630A (qee yam khoom tshiab tuaj yeem ncav cuag 1600A) hauv qab no. Nws tuaj yeem pom tias qhov ntsuas tam sim no ntawm cov kab hluav taws xob tawg yog loj dua, feem ntau yog 630A-6300A. Ib qho ntxiv, cov kab hluav taws xob cov khoom siv hluav taws xob siab dua MOLDED cov ntaub ntawv hluav taws xob cov khoom siv hluav taws xob hauv ntu muaj peev xwm.
Hauv daim ntawv thov ua haujlwm, Circuit Court saum toj no 800A lossis Circuit Court nrog qhov tshwj xeeb xav tau tshwj xeeb rau kev faib ua peev txheej lossis cov Circuit nrog ntau lub luag haujlwm yuav tsum siv cov txheej txheem Circuit Court breaker, thiab cov Circuit hauv qab 630A feem ntau siv cov txheej txheem Circuit Court breaker.
Txhua qhov ntawm cov kab hluav taws xob tau teeb tsa tau teeb tsa hauv cov hlau thaiv, feem ntau qhib hom, tuaj yeem teeb tsa nrog ntau yam khoom siv ntxiv, hloov kev sib cuag thiab cov khoom siv tau yooj yim dua, feem ntau nyob rau hauv lub zog kawg ntawm qhov hloov pauv tseem ceeb. Muaj ntau hom kev tshaj tawm tam sim no, xws li tso tawm hluav taws xob, tso tawm hluav taws xob thiab tso tawm ntse. Lub tshuab hluav taws xob hluav taws xob muaj plaub ntu kev tiv thaiv: ncua ntev, ncua sijhawm luv, tam sim ntawd thiab ua txhaum hauv av, thiab teeb tsa tus nqi ntawm txhua qhov kev tiv thaiv raug hloov kho hauv qee yam raws li chav kawm ntawm nws lub plhaub thav duab.
2, Mould Case Case Circuit Breaker - MCCB
Muaj peev xwm txiav tawm tam sim no thaum qhov tam sim no tshaj qhov teeb tsa. MCCBS feem ntau muaj cov khoom cua sov sib nqus, tab sis MCCBS loj dua yuav tuaj yeem nruab nrog lub xeev kev mus ncig ua haujlwm. Chav tsev mus ncig tau muab faib ua cua sov sib nqus mus ncig thiab hluav taws xob.
Kuj tseem raug xa mus ua lub tshuab hluav taws xob ntaus ntawv vim hais tias kev sib cuag sab nraud ntawm cov xov hlau hauv av, lub qhov quav, tso tawm, thiab cov txheej txheem ua haujlwm tau nyob hauv ib lub hnab yas. Lub koom haum pab tiv tauj, undervoltage tripping ntaus ntawv thiab shunt tripping ntaus ntawv yog modular, cov qauv me me, feem ntau tsis xav txog kev saib xyuas, haum rau kev tiv thaiv hloov ceg.
Nws siv phau ntawv ua haujlwm, lub peev xwm loj tuaj yeem xaiv hluav taws xob faib. Vim tias daim ntawv thov hluav taws xob tshaj tawm tam sim no, nws tuaj yeem muab faib ua ob hom: chav A thiab Chav B. Chav B muaj Qhov zoo peb ntu kev tiv thaiv tus yam ntxwv, tab sis vim yog tus nqi, kev lag luam feem ntawm cov khoom A siv cov cua sov sib nqus tso tawm yog siab dua.
Cov ntaub ntawv hluav taws xob hluav taws xob hluav taws xob dhau qhov kev mus los tam sim no muaj hluav taws xob thiab hluav taws xob ob yam, cov khoom siv hluav taws xob hluav taws xob tuaj yeem tsim hluav taws xob hluav taws xob tsis yog xaiv hluav taws xob hluav taws xob, tsuas yog ncua sijhawm ntev thiab tam sim ob yam kev tiv thaiv, hluav taws xob molded case Circuit Court breaker tau ncua ntev, ncua sijhawm luv, tam sim thiab hauv av txhaum plaub yam kev tiv thaiv kev ua haujlwm. Qee cov khoom lag luam tshiab ntawm hluav taws xob MCCB kuj tseem muaj cov haujlwm hauv cheeb tsam xaiv sib cuam tshuam.
3, cov khoom siv hluav taws xob me me - MCB
Nws yog cov khoom siv dav dav tshaj plaws tiv thaiv cov khoom siv hauv tsev tsim hluav taws xob cov khoom siv hluav taws xob xa tawm. Siv rau ib leeg-theem, peb-theem luv-Circuit, tshaj, tiv thaiv hluav taws xob ntau dua 125A, suav nrog unipolar 1P, 2P, 3P, 4P thiab ntxiv rau.
Hauv kev tsim cov tuam tsev pej xeem, cov hluav taws xob qis hluav taws xob hluav taws xob feem ntau yog siv rau kev hla dhau, luv Circuit Court, dhau-tam sim no, qhov hluav taws xob poob qis, tsis muaj zog, hauv av, txau, tsis siv neeg hloov pauv ntawm ob lub zog thiab lub cev tsis siv neeg pib (9 yam) tiv thaiv, kev ua haujlwm thiab lwm lub hom phiaj.
Qhov sib txawv ntawm cov khoom siv hluav taws xob ua ntej
ACB- universal (hom hom) Circuit breaker, MCCB- molded case circuit breaker, MCB- cov khoom siv hluav taws xob me me, ELCB- qhov hluav taws xob Circuit Court breaker yog qhov sib txawv tseem ceeb:
(1) Lub peev xwm tawg ntawm ACB yog qhov siab, MCCB yog qhov thib ob thiab MCB yog qhov phem tshaj.
(2) qhov chaw teeb tsa, ACB tau lees paub tias yog lub tshuab hluav taws xob tseem ceeb (lub zog hloov hluav taws xob), vim nws tus kheej muaj lub sijhawm ncua kev ua haujlwm, tuaj yeem ncua tus neeg tawg thiab thawb, tab sis kuj tseem muaj kev sib txuas lus zoo heev thiab xaiv tau, thaum MCCB tau txais los ua lub zog faib hluav taws xob, nyob hauv nruab nrab ntawm txoj kab, vim tias nws tsuas muaj peev xwm ua kom tawg thiab lub sijhawm thim rov qab muaj peev xwm, Tsis muaj kev xaiv, feem ntau tsuas yog siv los ua tus tiv thaiv kev hloov pauv, nres xwm txheej ceev HW; MCB feem ntau yog siv rau sab nraub qaum, vim tias nws lub peev xwm tawg yog qis dua ib nrab ntawm 6000A thiab 4500A;
(3) Sab nrauv qhov ntev kuj txawv heev. MCB muaj qhov ntim me me thiab teeb tsa tau yooj yim, thaum ACB muaj qhov ntim loj tshaj plaws thiab teeb tsa tau yooj yim, thiab MCCB nyob hauv nruab nrab.
