Yuav tsum muaj ntau dua lossis sib npaug li 1.25 npaug ntawm qhov teeb tsa tam sim no ntawm kev tso tawm tam sim ntawm lub Circuit Court breaker.Qhov ntsuas hluav taws xob ntawm qhov hluav taws xob tso tawm ntawm lub Circuit Court breaker yuav tsum sib npaug rau cov ntsuas hluav taws xob ntawm cov kab hluav taws xob.Cov ntsuas hluav taws xob ntawm shunt tso tawm ntawm lub Circuit Court breaker yuav tsum sib npaug rau kev tswj fais fab mov voltage.Qhov ntsuas kev khiav hauj lwm voltage ntawm lub tshuab hluav taws xob yuav tsum tau tso cai sib npaug ntawm cov khoom siv hluav taws xob. Qee cov qauv ntawm Circuit Court breakers tsuas yog tso cai rau cov kab nkag los ntawm sab saum toj, thaum qee cov qauv tso cai rau cov kab nkag los ntawm sab saum toj lossis hauv qab.

Cov hauv paus ntsiab lus rau xaiv cov hluav taws xob hluav taws xob qis hluav taws xob

1.Kev txiav txim siab hom thiab kev tiv thaiv daim ntawv ntawm lub Circuit Court breaker raws li kev tiv thaiv ntawm cov kab: xaiv thav duab hom, hom khoom siv lossis hom txwv tam sim no, thiab lwm yam.
Cov khoom siv hom Circuit Court breaker: Nws muaj lub plhaub yas insulating, built-in contact system, arc extinguishing chamber thiab tso tawm, thiab lwm yam, thiab tuaj yeem raug kaw manually lossis hluav taws xob (rau cov hluav taws xob muaj peev xwm loj). Nws muaj zog tawg muaj peev xwm, siab dynamic stability, thiab kuj ua tiav xaiv kev tiv thaiv kev ua haujlwm. Nws yog dav siv nyob rau hauv kev faib kab. Tam sim no, cov khoom siv feem ntau suav nrog DZ15, DZ20, DZX19, C45N (tam sim no hloov kho rau C65N) thiab lwm yam. Ntawm lawv, C45N (C65N) Circuit Court breakers muaj qhov zoo ntawm qhov me me, muaj peev xwm tawg, muaj peev xwm ua tau zoo tam sim no, kev ua haujlwm yooj yim, thiab ua tiav cov qauv thiab cov lus qhia tshwj xeeb. Lawv tuaj yeem yooj yim ua ke rau hauv ob-ncej, peb-ncej thiab plaub-ncej Circuit Court breakers raws li cov qauv ib-ncej, thiab tau siv dav hauv cov teeb pom kev zoo hauv pej xeem thiab cov ceg ntoo ntawm 60A thiab hauv qab no (feem ntau yog siv rau cov kab nkag mus rau cov neeg siv nyob hauv tsev thiab cov chaw teeb pom kev zoo hauv khw muag khoom).
2.Frame-type low-voltage circuit breakers: muaj peev xwm loj, muaj zog luv luv-circuit breaking muaj peev xwm, siab dynamic stability, haum rau AC 50Hz, rated voltage 380V tis network, raws li lub ntsiab kev tiv thaiv ntawm tis lub cev kab. Ncej-hom Circuit Court breakers yog tsim los ntawm kev sib cuag, kev khiav hauj lwm mechanism, overcurrent tso, shunt tso, undervoltage tso, accessories thiab ncej, thiab lwm yam. Tag nrho cov Cheebtsam yog insulated thiab ntsia rau ntawm tus ncej qauv puag. Tam sim no, feem ntau siv cov ncej-hom qis-voltage Circuit Court breakers hauv kuv lub teb chaws yog DW15, ME, AE, AH thiab lwm yam. Lub DW15 series Circuit Court breakers yog tsim thiab tsim nyob rau hauv kuv lub teb chaws. Cov kab tag nrho suav nrog ntau tus qauv xws li 1000, 1500, 2500, thiab 4000A. ME, AE, thiab AH series Circuit Court breakers yog tsim los ntawm kev siv thev naus laus zis, nrog cov kev qhia tshwj xeeb thiab cov qauv (Kuv hloov cov qib tam sim no ntawm 630A txog 5000A, tag nrho ntawm 13 qib), thiab cov qhab nia tawg muaj zog dua li ntawm DW15. Lawv feem ntau siv rau kev tiv thaiv tseem ceeb ntawm cov khoom siv hluav taws xob tsawg tsawg.
3.Intelligent circuit breakers: Tam sim no, muaj ob hom ntse Circuit Court breakers uas tsim nyob rau hauv kuv lub teb chaws: thav duab hom thiab yas plhaub hom. Ncej hom ntse Circuit Court breakers feem ntau yog siv los ua lub ntsiab Circuit Court breakers rau ntse tsis siv neeg tis systems, thaum yas plhaub hom ntse Circuit Court breakers yog tsuas yog siv rau lub hwj chim tis nyob rau hauv tis tes hauj lwm thiab tswj thiab kev tiv thaiv ntawm kab thiab cov khoom siv fais fab. Siv raws li kev tswj ntawm peb-theem tawb asynchronous motors. Cov yam ntxwv ntawm cov ntse Circuit Court breakers yog tias lawv siv cov tswj kev txawj ntse (ntse mus txawv tebchaws cov khoom siv) nrog microprocessors lossis ib leeg-chip microcomputers ua lub hauv paus, thiab muaj cov haujlwm ntawm kev saib xyuas online, tsis siv neeg hloov, ntsuas, ntsuas, ntsuas tus kheej, kev sib txuas lus, thiab lwm yam ntawm cov hluav taws xob tsis sib xws ntawm Circuit Court (tam sim no, voltage, hwj chim), muaj peev xwm saib xyuas thiab ntsuas ntau yam, thiab lwm yam. ua haujlwm, hloov kho qhov tsis ua txhaum thaum lub ntsuas hluav taws xob tiv thaiv ua haujlwm, thiab khaws cov kev txwv no hauv lub cim xeeb uas tsis yog-volatile rau cov lus nug. Cov qauv hluav taws xob hluav taws xob hauv tsev muaj xws li DW45, DW40, DW914 (AH), DW18 (AE-S), DW48, DW19 (3WE), DW17 (ME), thiab lwm yam.

Thaum xaiv lub Circuit Court breaker, cov hauv qab no yuav tsum tau xav txog:

1. Qhov ntsuas hluav taws xob (UN) ntawm lub ntsuas hluav taws xob yuav tsum sib npaug los yog ntau dua li qhov ntsuas hluav taws xob ntawm cov kab tiv thaiv.
2. Qhov ntsuas hluav taws xob ntawm lub Circuit Court breaker qhov kev tso tawm undervoltage yuav tsum phim qhov ntsuas hluav taws xob ntawm cov kab tiv thaiv.
3. Qhov ntsuas tam sim no ntawm lub Circuit Court breaker thiab nws cov overcurrent tso tawm yuav tsum ntau dua los yog sib npaug rau cov xam tam sim no ntawm cov tiv thaiv Circuit Court.
4. Qhov kawg tawg peev xwm ntawm lub Circuit Court breaker yuav tsum tshaj qhov zoo ntawm qhov siab tshaj plaws luv luv tam sim no nyob rau hauv kab.
5. Cov yam ntxwv kev tiv thaiv ntawm lub sab sauv thiab sab hauv Circuit Court breakers nyob rau hauv cov kab sib faib yuav tsum tau sib koom ua ke, nrog rau cov yam ntxwv ntawm kev tiv thaiv qib qis nyob rau hauv qab no thiab tsis cuam tshuam nrog cov yam ntxwv tiv thaiv sab saud.
6. Lub sij hawm ncua sij hawm ntev tripping tam sim no ntawm Circuit Court breaker yuav tsum tsawg tshaj li qhov tso cai txuas ntxiv tam sim no ntawm cov hlau.

Rau cov hluav taws xob faib hluav taws xob hluav taws xob hluav taws xob, cov txheej txheem xaiv hauv qab no siv:

1. Kev teeb tsa tus nqi ntawm lub Circuit Court breaker lub sij hawm ntev ua haujlwm tam sim no yuav tsum tsis pub tshaj qhov tso cai nqa lub peev xwm ntawm cov xaim. Rau cov ntawv thov hlau thiab cable, nws raug nquahu kom siv 80% ntawm cov xaim thiab cable tso cai tam sim no nqa lub peev xwm.
2. Lub sij hawm rov qab mus rau peb lub sij hawm ncua sij hawm ncua kev khiav hauj lwm tam sim no tus nqi yuav tsum ntau dua los yog sib npaug rau lub sij hawm pib ntawm lub cev muaj zog nrog qhov siab tshaj plaws pib tam sim no hauv kab.
3. Tus nqi tam sim no yuav tsum yog tsawg kawg yog 1.1 npaug ntawm cov lej ntawm cov kab laij lej load tam sim no (Ijx) thiab cov khoom ntawm lub cev muaj zog pib tam sim no cuam tshuam coefficient (k1, feem ntau 1.7-2), lub cev muaj zog pib tam sim no ntau yam (k), thiab cov ntsuas tam sim no ntawm lub cev muaj zog loj tshaj plaws (ICdm).

Rau lub cev muaj zog tiv thaiv Circuit Court breakers, xaiv cov hauv qab no siv tau:

1. Lub sij hawm ncua sij hawm ncua tam sim no tus nqi yuav tsum sib npaug ntawm lub cev muaj zog qhov ntsuas tam sim no.
2. Qhov teeb tsa tam sim no rau cov hluav taws xob thaiv hluav taws xob tiv thaiv lub tawb motors yuav tsum yog 8-15 npaug ntawm lub cev muaj zog tam sim no, thaum lub qhov txhab rotor motors yuav tsum yog 3-6 npaug ntawm lub cev muaj zog tam sim no.
3. Lub sij hawm rov qab tau rau lub sij hawm ncua sij hawm ncua sij hawm tam sim no yuav tsum ntau dua lossis sib npaug ntawm lub sijhawm pib lub cev muaj zog, nrog rau kev xaiv ntawm 1S, 3S, 5S, 8S, 12S, lossis 15S raws li qhov hnyav ntawm qhov pib.

Thaum sib koom ua ke Circuit Court breakers thiab fuses, cov hauv qab no yuav tsum tau xav txog:

1. Yog tias qhov kev cia siab luv luv tam sim no ntawm qhov chaw teeb tsa tsawg dua li qhov ntsuas hluav taws xob hauv Circuit Court breaker, lub fuse tuaj yeem siv los tiv thaiv kev tiv thaiv vim nws muaj zog ntsuas luv luv-circuit breaking peev xwm. Raws li pom nyob rau hauv daim duab 1, lub backup fuse tus yam ntxwv (1) cuam tshuam nrog lub Circuit Court breaker tus yam ntxwv (2). Nyob rau hauv qhov kev tshwm sim ntawm ib tug kab luv luv-circuit, lub fuse lub sij hawm tawg yog luv dua lub Circuit Court breaker's, xyuas kom meej lub Circuit Court breaker txoj kev nyab xeeb. Qhov kev hloov pauv ntawm cov yam ntxwv tuaj yeem xaiv tau ntawm 80% ntawm Circuit Court breaker qhov ntsuas luv luv-circuit breaking peev.
2. Lub fuse yuav tsum tau nruab rau ntawm lub hwj chim sab ntawm lub Circuit Court breaker kom ntseeg tau tias kev siv nyab xeeb.
