Functions, Cheebtsam thiab specifications ntawm molded case Circuit Court breakers

I. Yas Case Circuit Breaker (MCCB): Muaj nuj nqi thiab cov lus piav qhia

Hauv ntiaj teb niaj hnub no, qhov kev thov rau hluav taws xob tau nce ntxiv. Tsis tsuas yog peb yuav tsum paub txog tus nqi ntawm hluav taws xob thaum lub sij hawm tsis txaus, tab sis peb yuav tsum xyuas kom meej tias peb khaws nws txoj hauv kev zoo. Txhawm rau daws qhov teeb meem no, cov kev tswj fais fab raug teeb tsa los saib xyuas qhov tam sim no. Qee zaum, overloads thiab luv luv Circuit Court tuaj yeem ua rau lub cev puas tsuaj. Tsawg-voltage switchgear yog siv los tiv thaiv Circuit Court thaum tsis paub tseeb. Hauv tsab xov xwm no, peb yuav nthuav qhia dab tsi yog molded case Circuit Court breaker? Thiab muaj nuj nqi, Cheebtsam thiab specifications ntawm molded case Circuit Court breaker.

II. MCCB yog dab tsi

MCCB yog ib qho luv luv rau yas-cov ntaub ntawv Circuit Court breaker siv los tiv thaiv circuits thiab lawv cov khoom los ntawm overcurrent. Yog tias qhov tam sim no tsis raug cais tawm ntawm lub sijhawm, nws yuav ua rau muaj kev cuam tshuam ntau dhau lossis luv luv. Cov khoom siv no muaj ntau qhov ntau zaus, uas ua rau lawv haum rau ntau yam kev siv los tiv thaiv circuits. Lawv muaj nyob rau hauv qhov ntsuas tam sim no los ntawm 15 amps txog 1600 amps thiab tuaj yeem siv rau hauv cov ntawv thov hluav taws xob tsawg. Koj tuaj yeem mus saib peb lub vev xaib ntawm www.ace-reare.com. Yuav Acereare Electric MCCB ntawm tus nqi zoo tshaj.

III. Kev ua haujlwm ntawm cov ntaub ntawv yas Circuit Court breaker

● Kev tiv thaiv overload
● Kev tiv thaiv hluav taws xob yuam kev
● Qhib thiab kaw lub voj voog

MCCBS tuaj yeem raug txiav tawm thiab siv manually thiab tseem siv tau los ua lwm txoj hauv kev microcircuit breakers hauv photovoltaic systems. Cov ntaub ntawv molded Circuit Court breaker yog ntsia rau hauv lub tsev molded los tiv thaiv nws ntawm plua plav, nag, roj thiab lwm yam tshuaj.

Txij li cov cuab yeej no tswj cov dej ntws siab, lawv xav tau kev saib xyuas kom zoo ib ntus, uas tuaj yeem ua tiav los ntawm kev tu, lubrication, thiab kev sim.

IV. Tiv thaiv koj cov khoom siv hluav taws xob

Txhua yam ntawm koj cov khoom siv hluav taws xob xav tau ib qho tam sim no kom ua haujlwm zoo. Nws yog ib qho tseem ceeb rau nruab MCCB lossis MCB raws li cov khoom thauj tam sim no. Los ntawm kev ua li ntawd, cov txheej txheem kev tswj hwm lub tshuab muaj peev xwm tiv thaiv tau los ntawm kev cais cov khoom siv hluav taws xob thaum muaj hluav taws xob tsis ua haujlwm.

V. Tsis txhob tua hluav taws

Ib qho MCCB uas ua tau raws li cov qauv kev lag luam thiab cov khoom zoo yog pom zoo kom ua kom muaj kev nyab xeeb siab tshaj plaws. Cov khoom siv hluav taws xob electromagnetic no ntes tau qhov tsis raug thaum muaj hluav taws xob tawg lossis luv luv los tiv thaiv lawv ntawm hluav taws kub, kub thiab tawg.

VI. Cheebtsam thiab specifications ntawm molded case Circuit Court breakers

Plaub yam tseem ceeb ntawm lub rooj plaub molded Circuit Court breaker suav nrog
• Plhaub
• Kev khiav hauj lwm mechanism
• Arc extinguishing system
• Cov cuab yeej mus txawv tebchaws (kwv yees los yog mus txawv tebchaws electromagnetic)

SHELL

Kuj hu ua vaj tse, nws muab qhov chaw rau cov vaj tse insulated rau nruab tag nrho cov Circuit Court breaker Cheebtsam. Nws yog ua los ntawm thermosetting composite resin (DMC cov khoom siv loj) los yog iav polyester (txhaj tshuaj molded qhov chaw) los muab lub zog dielectric siab hauv nws cov qauv tsim. Lub npe no yog muab raws li hom thiab qhov loj ntawm cov ntaub ntawv molded thiab yog siv ntxiv los piav qhia txog cov yam ntxwv ntawm Circuit Court breaker (qhov siab tshaj plaws voltage thiab ntsuas tam sim no).

Kev ua haujlwm mechanism

Qhov qhib thiab kaw ntawm qhov kev sib cuag yog ua tiav los ntawm kev ua haujlwm mechanism. Qhov ceev ntawm qhov kev sib cuag tau qhib thiab kaw nyob ntawm seb tus kov txav nrawm npaum li cas. Yog hais tias kev sib cuag mus ncig, koj yuav pom tau tias tus kov yog nyob rau hauv nruab nrab txoj hauj lwm. Yog hais tias lub Circuit Court breaker nyob rau hauv txoj hauj lwm, nws yog tsis yooj yim sua kom nws mus txawv tebchaws, uas yog tseem hu ua "automatic trip".

Thaum lub Circuit Court breaker yog tripped, uas yog, yog hais tias tus kov yog nyob rau hauv nruab nrab txoj hauj lwm, nws yuav tsum xub tsiv mus rau lub off txoj hauj lwm thiab ces mus rau ntawm txoj hauj lwm. Nyob rau hauv cov rooj plaub uas cov hluav taws xob hluav taws xob tau teeb tsa hauv ib pab pawg (xws li lub tshuab hluav taws xob), cov haujlwm sib txawv pab kom nrhiav tau qhov tsis raug ntawm Circuit Court.
Feem ntau, ua ntej lub Circuit Court breaker tawm ntawm lub Hoobkas, peb yuav xyuas qhov qhib thiab kaw ntawm Circuit Court breaker overload thiab luv luv Circuit Court nyob rau hauv ib-theem thiab dual-theem txoj kev los saib xyuas seb lub Circuit Court breaker yog tripped nyob rau hauv lub teeb ntau yam nqi kom paub meej tias lub Circuit Court breaker. kev ruaj ntseg ntawm lub Circuit Court breaker nyob rau hauv qhov tseeb siv ntawm qhov chaw.

Arc-extinguishing system

Arc interrupter: Arcing tshwm sim thaum lub Circuit Court breaker cuam tshuam qhov tam sim no. Lub luag haujlwm ntawm tus cuam tshuam yog kaw thiab faib cov arc, yog li tua nws. Lub arc extinguishing chamber yog nyob rau hauv ib tug high-lub zog insulated lub thawv, uas yog tsuas yog tsim los ntawm ib tug xov tooj ntawm arc extinguishing daim phiaj daim, uas ua lub luag hauj lwm tseem ceeb nyob rau hauv arc pib thiab arc extinguishing nyob rau hauv tsawg-voltage hluav taws xob khoom. Thaum kev sib cuag sib cais vim muaj kev cuam tshuam, tam sim no ntws los ntawm thaj tsam ionized ntawm kev sib cuag tsim ib qho chaw sib nqus nyob ib ncig ntawm lub arc thiab qhov cuam tshuam.

Cov kab hlau nplaum tsim nyob ib ncig ntawm lub arc tsav lub arc rau hauv cov hlau phaj. Tom qab ntawd cov roj yog deionized, sib cais los ntawm ib qho arc, cia nws txias. Standard MCCBS siv ib tug linear tam sim no los ntawm kev sib cuag, uas, nyob rau hauv luv luv Circuit Court tej yam kev mob, tsim ib tug me me tawg quab yuam, uas yuav pab qhib kev sib cuag.

Feem ntau ntawm qhov qhib qhov kev txiav txim yog tsim los ntawm cov neeg kho tshuab lub zog khaws cia rau hauv lub tripping mechanism nws tus kheej. Qhov no yog vim hais tias tam sim no nyob rau hauv ob qho tib si kev sib cuag ntws nyob rau hauv tib direct tam sim no.

Trip device (thermal lossis electromagnetic trip)

Cov khoom siv mus txawv tebchaws yog lub paj hlwb ntawm Circuit Court breaker. Lub luag haujlwm tseem ceeb ntawm cov cuab yeej tripping yog mus ncig ua haujlwm ntawm kev ua haujlwm hauv cov ntaub ntawv luv luv lossis txuas txuas ntxiv tam sim no. Ib txwm pwm-cov ntaub ntawv Circuit Court breakers siv electromechanical tripping li. Circuit Court breakers muaj kev tiv thaiv los ntawm kev sib txuas cov cuab yeej ntsuas kub nrog cov khoom siv hluav taws xob mus ncig, uas tam sim no tuaj yeem muab kev tiv thaiv ntau dua thiab saib xyuas. Feem ntau molded case Circuit Court breakers siv ib lossis ntau qhov sib txawv mus txawv tebchaws los muab kev tiv thaiv Circuit Court rau ntau yam kev siv. Cov ntsiab lus tripping no tiv thaiv thermal overloads, luv circuits thiab arc hauv av tsis ua hauj lwm.

Cov pa MCCBS muab cov khoom ruaj khov lossis sib hloov tau electromechanical tripping. Yog tias ib qho kev mus ncig ruaj khov Circuit Court breaker xav tau qhov ntsuas kev mus ncig tshiab, tag nrho Circuit Court breaker yuav tsum tau hloov. Cov khoom siv sib hloov pauv tau kuj tseem hu ua cov ntsaws ntsaws. Qee qhov Circuit Court breakers muab kev sib hloov ntawm cov khoom siv hluav taws xob thiab hluav taws xob mus ncig hauv tib lub thav duab.

Txhawm rau kom muaj kev ua haujlwm zoo ntawm MCCB, kev saib xyuas tsis tu ncua yuav tsum tau ua, suav nrog kev tshuaj xyuas qhov muag, ntxuav thiab kuaj.

VII. Kev siv molded case Circuit Breaker

MCCB yog tsim los tswj cov dej ntws siab thiab tau siv dav hauv cov ntawv thov hnyav xws li kev hloov pauv mus txawv tebchaws rau cov ntawv thov tam sim no qis, kev tiv thaiv lub cev muaj zog, kev tiv thaiv lub tsev txhab nyiaj capacitor, vuam, kev tiv thaiv lub tshuab hluav taws xob thiab cov khoom noj.
