Moulded Case Circuit Breaker (MCCB): Ua kom muaj kev nyab xeeb thiab kev ntseeg tau

Cov Moulded Case Circuit Breaker(MCCB)yog ib qho tseem ceeb ntawm cov hluav taws xob faib hluav taws xob, tsim los tiv thaiv hluav taws xob hluav taws xob los ntawm kev puas tsuaj los ntawm overloads, luv circuits, thiab av txhaum. Nws txoj kev tsim kho muaj zog, ua ke nrog cov txheej txheem siab heev, ua kom muaj kev ruaj ntseg thiab ruaj ntseg ntawm cov khoom siv hluav taws xob thoob plaws hauv kev lag luam, kev lag luam, thiab kev siv hauv tsev.

Taw qhia rauMCCBs

MCCBs muaj npe tom qab lawv cov qauv tsim tshwj xeeb, qhov twg cov khoom siv hluav taws xob hauv hluav taws xob tau ntim rau hauv ib lub tsev molded, insulated yas vaj tse. Lub vaj tsev no muab kev tiv thaiv zoo tshaj plaws tiv thaiv ib puag ncig xws li plua plav, dej noo, thiab kev sib cuag ntawm lub cev, ua rau lawv ruaj khov thiab txhim khu kev qha rau ntau qhov chaw ua haujlwm. Cov breakers no tuaj nyob rau hauv ntau qhov ntau thiab tsawg, tso cai rau ntau yam kev ntsuas tam sim no thiab qhov hluav taws xob kom haum rau cov kev siv sib txawv.

MCCBs sawv tawm vim lawvcompact tsim, siab interrupting peev, thiabkev ntseeg tau. Cov yam ntxwv no ua rau lawv tsis tuaj yeem siv rau hauv cov xwm txheej uas qhov kev ua haujlwm zoo sib xws thiab kev nyab xeeb ntawm cov hluav taws xob hluav taws xob yog qhov tseem ceeb, los ntawm kev teeb tsa me me mus rau kev lag luam loj.

Lub luag haujlwm tseem ceeb ntawm MCCBs

Moulded Case Circuit Breakers ua haujlwm ntau lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm cov hluav taws xob circuits:

1. Kev tiv thaiv overload

MCCBs tau nruab nrog kev tiv thaiv thermal uas teb rau cov xwm txheej tsis tu ncua. Thaum ib qho overload tshwm sim, qhov nce tam sim no ua rau lub caij thermal kom sov. Raws li qhov kub thiab txias, nws thiaj li ua rau cov txheej txheem mus txawv tebchaws, rhuav tshem lub voj voog thiab tiv thaiv kev puas tsuaj ntxiv. Qhov kev cuam tshuam tsis siv neeg no tiv thaiv cov khoom siv hluav taws xob thiab cov xaim hluav taws xob los ntawm overheating, txo qhov kev pheej hmoo ntawm hluav taws.

2. Kev tiv thaiv luv luv

Nyob rau hauv qhov kev tshwm sim ntawm ib tug luv luv Circuit Court, qhov twg cov ntws ntawm tam sim no bypasses lub load thiab tsim ib tug ncaj qha txoj kev ntawm lub hwj chim qhov chaw thiab hauv av, MCCBs siv ib tug sib nqus mus txawv tebchaws mechanism. Cov txheej txheem no ua haujlwm tam sim ntawd, feem ntau hauv milliseconds, cuam tshuam qhov ntws ntawm tam sim no. Cov lus teb ceev ceev ntawm MCCB tiv thaiv kev puas tsuaj loj rau cov khoom siv thiab cov xaim hluav taws xob, thaum tseem txo qhov kev pheej hmoo ntawm hluav taws xob hluav taws xob.

3. Kev tiv thaiv av txhaum

Kev ua txhaum hauv av tshwm sim thaum tam sim no khiav tawm ntawm nws txoj kev npaj thiab pom txoj hauv kev mus rau hauv av, uas yuav ua rau muaj kev phom sij lossis kev puas tsuaj rau cov khoom siv. MCCBs tuaj yeem tshawb xyuas qhov ua txhaum hauv av thiab tawm mus tam sim kom cais qhov txhaum thiab tiv thaiv ob qho tib si cov cuab yeej thiab cov neeg ua haujlwm los ntawm kev puas tsuaj.

4. Kev tswj xyuas kev tuav tswj

MCCBs kuj tau tsim los rau kev tuav haujlwm, tso cai rau cov neeg sivmanually qhib lossis kawtus breaker. Cov yam ntxwv no yog qhov tseem ceeb rau kev cais cov hluav taws xob hluav taws xob thaum lub sij hawm tu, kev sim, lossis kev hloov kho qhov system, ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm saib xyuas los ntawm kev tiv thaiv kev sib tsoo rov ua dua tshiab.

Kev ua haujlwm ntawm MCCBs

Kev khiav hauj lwm ntawm MCCB revolves nyob ib ncig ntawm ob qho tseem ceeb mus txawv tebchaws mechanisms:kev tiv thaiv thermalthiabkev tiv thaiv hlau nplaum.

Kev tiv thaiv cua sov

Kev tiv thaiv cua sov yog muab los ntawm ib txoj hlua bimetallic hauv lub breaker. Thaum lub sijhawm ua haujlwm ib txwm muaj, cov kab xev bimetallic tseem txias thiab lub breaker tseem raug kaw, cia tam sim no ntws. Thaum ib qho overload tshwm sim, tam sim no nce, ua rau lub bimetallic strip kom sov thiab khoov. Qhov no khoov nws thiaj li mus ncig lub breaker, txiav tawm lub hwj chim mov. Kev tiv thaiv thermal yog qhov zoo tshaj plaws rau kev tiv thaiv overloads uas tsim los ntawm lub sij hawm, kom ntseeg tau tias lub breaker teb tau zoo yam tsis muaj kev cuam tshuam tsis tsim nyog.

Kev Tiv Thaiv Sib Nqus

Sib nqus kev tiv thaiv, ntawm qhov tod tes, yog tsim los teb tam sim ntawd rau luv luv circuits. Lub kauj nyob rau hauv lub breaker tsim ib qho chaw sib nqus thaum ib qho luv luv Circuit Court tshwm sim, ua rau lub plunger mus rau lub breaker yuav luag tam sim ntawd. Cov lus teb tam sim no yog qhov tseem ceeb rau kev txwv qhov kev puas tsuaj los ntawm luv luv Circuit Court, tiv thaiv ob qho tib si thaiv thiab cov khoom siv txuas nrog.

Adjustable Trip Settings

Ntau MCCBs tau nruab nrog cov kev hloov pauv mus txawv tebchaws, tso cai rau tus neeg siv los kho qhov cuam tshuam cov lus teb rau overloads thiab luv circuits. Qhov kev hloov kho no ua rau lub tshuab hluav taws xob tau teeb tsa raws li cov yam ntxwv tshwj xeeb ntawm cov khoom siv hluav taws xob, ua kom muaj kev tiv thaiv zoo yam tsis muaj kev cuam tshuam kev ua haujlwm.

Hom ntawm MCCBs

MCCBs tuaj nyob rau hauv ntau hom, categorized raws li lawv cov kev ntsuam xyuas tam sim no, qhov ntsuas hluav taws xob, thiab cov chaw ua haujlwm. Ntawm no yog cov pawg tseem ceeb:

1. Thermal Magnetic MCCBs

Cov no yog hom MCCBs ntau tshaj plaws, muaj kev tiv thaiv thermal thiab sib nqus. Lawv tsim nyog rau ntau yam kev siv, los ntawm cov tsev me me mus rau kev lag luam loj. Lawv versatility thiab kev ua tau zoo ua rau lawv muaj kev xaiv nrov rau kev tiv thaiv hluav taws xob.

2. Electronic Trip MCCBs

Hauv kev mus ncig hauv hluav taws xob MCCBs, cov txheej txheem mus ncig yog tswj hluav taws xob, muab kev tiv thaiv ntau dua. Cov breakers no feem ntau tuaj nrog cov yam ntxwv siab heev xws li kev saib xyuas lub sijhawm tiag tiag, kev kuaj mob, thiab kev sib txuas lus muaj peev xwm, ua rau lawv zoo tagnrho rau cov tshuab hluav taws xob nyuaj hauv kev lag luam ib puag ncig.

3. Residual Current MCCBs

Residual MCCBs tam sim no muab kev tiv thaiv kev ua txhaum hauv av thiab cov dej xau. Lawv feem ntau yog siv rau hauv daim ntawv thov uas muaj kev pheej hmoo ntawm kev poob siab los yog qhov twg cov dej xau tam sim no yuav tsum tau saib xyuas zoo.

4. Tam sim no txwv MCCBs

Cov MCCBs no yog tsim los txwv qhov siab tshaj tam sim no thaum lub sij hawm luv luv, txo lub zog tso tawm thaum lub sij hawm ua txhaum. Qhov no txo ​​qis cov thermal thiab mechanical kev ntxhov siab ntawm cov hluav taws xob, pab tiv thaiv kev puas tsuaj rau cov khoom siv thiab kev xaim.

Qhov tseem ceeb ntawm MCCBs

MCCBs tau txais kev pom zoo hauv cov tshuab hluav taws xob niaj hnub no rau ntau qhov laj thawj:

1. Siab Interrupting Peev Xwm

MCCBs muaj peev xwm cuam tshuam qhov cuam tshuam loj tam sim no yam tsis muaj kev puas tsuaj rau lawv cov khoom sab hauv. Qhov no ua rau lawv zoo tagnrho rau siv nyob rau hauv ib puag ncig uas yuav tsum muaj kev txhaum tam sim no, xws li kev lag luam thiab chaw lag luam.

2. Ntau yam kev ntsuas

MCCBs muaj nyob rau ntau yam ntawm qhov tam sim no thiab qhov ntsuas hluav taws xob, los ntawm qis li 15 amperes mus rau ntau dua 2,500 amperes, thiab qhov ntsuas hluav taws xob mus txog 1,000 volts. Qhov no ua rau lawv haum rau ntau yam kev siv, los ntawm cov tsev nyob me me mus rau kev lag luam loj.

3. Compact Design

Txawm hais tias lawv muaj peev xwm cuam tshuam ntau thiab kev tsim kho, MCCBs yog qhov sib txuam. Qhov kev tsim qauv compact no tso cai rau kev teeb tsa yooj yim dua hauv qhov chaw nruj, txo cov hneev taw ntawm cov hluav taws xob hluav taws xob thiab cov khoom faib tawm.

4. Kho tau

Cov chaw mus txawv tebchaws ntawm MCCBs tuaj yeem hloov kho kom haum rau cov kev xav tau tshwj xeeb ntawm cov tshuab hluav taws xob. Qhov kev hloov pauv no tso cai rau cov neeg siv los ua kom zoo dua qhov kev ua haujlwm ntawm lub tshuab tawg rau cov kev siv sib txawv, ua kom muaj kev tiv thaiv siab tshaj plaws.

5. Durability thiab Environmental Protection

Lub molded yas casing ntawm MCCB muab rwb thaiv tsev thiab tiv thaiv plua plav, ya raws, thiab lwm yam ib puag ncig. Qhov no ua rau MCCBs ruaj khov thiab tsim nyog siv rau hauv qhov chaw hnyav uas muaj kev ntseeg siab yog qhov tseem ceeb.

Kev siv ntawm MCCBs

MCCBs tau siv dav hauv ntau yam kev siv, suav nrog:

• Industrial Facilities:Hauv kev lag luam ib puag ncig, MCCBs yog qhov tseem ceeb rau kev tiv thaiv cov tshuab, lub cev muaj zog, thiab hluav taws xob xa hluav taws xob los ntawm kev puas tsuaj los ntawm kev ua txhaum.
• Cov tsev lag luam:MCCBs ua kom muaj kev nyab xeeb ntawm cov hluav taws xob hluav taws xob hauv cov tsev lag luam, tiv thaiv kev ua txhaum cai uas tuaj yeem cuam tshuam kev ua haujlwm lossis ua rau muaj kev nyab xeeb rau cov neeg nyob.
