Teb ceev
A Core BalanceTam sim no Transformer(CBCT) yog ib qho tshwj xeeb toroidal transformer siv los kuaj xyuas lub ntiaj teb to thiab av txhaum hauv cov tshuab hluav taws xob. Nws ua haujlwm los ntawm kev saib xyuas cov vector sum ntawm cov dej ntws los ntawm nws cov tub ntxhais. Nyob rau hauv tej yam kev mob, tus lej yog xoom; Thaum lub ntiaj teb ua txhaum, qhov tsis sib haum xeeb tsim cov seem tam sim no, ua rau muaj kev tiv thaiv relay mus rau lub voj voog.

Vim li cas thiaj xaiv CBCT zoo? Rau kev tiv thaiv txhim khu kev qha, ib txwm muab los ntawm cov kws tshaj lij CBCT cov chaw tsim khoom nrog ISO- ntawv pov thawj kev tswj hwm zoo thiab OEM muaj peev xwm kho tau.

 

CBCT Ua li cas?
CBCT sawv cev rau Core Balance Current Transformer. Nws kuj tau paub dav hauv kev lag luam raws li Zero Sequence Tam Sim No Transformer (ZSCT) lossis Residual Current Transformer. Cov ntsiab lus no feem ntau siv sib hloov hauv cov ntaub ntawv kev tshaj lij thiab phau ntawv tiv thaiv relay.

Kev nkag siab cov ntsiab lus no yog qhov tseem ceeb thaum tshawb nrhiav cov neeg muab khoom lossis sib piv CBCT cov khoom lag luam catalogs, vim cov cheeb tsam sib txawv yuav nyiam cov npe sib txawv.

 

CBCT ua haujlwm li cas? (Txoj Cai Ua Haujlwm)
Lub hauv paus ntsiab lus ua haujlwm ntawm CBCT yog nruj me ntsis raws li Kirchhoff Txoj Cai Tam Sim No thiab electromagnetic induction.

✅ Ib txwm mob (Balanced State)
Hauv peb theem kev noj qab haus huv -theem (nrog lossis tsis muaj nruab nrab), phasor sum ntawm cov dej ntws los ntawm lub qhov rais CBCT yog xoom. Cov sib nqus fluxes tsim los ntawm txhua tus neeg xyuas pib tshem tawm, ua rau tsis muaj qhov tso tawm tam sim no mus rau lub relay.

⚠️ Lub Ntiaj Teb Fault Condition (Unbalanced State)
Thaum lub rwb thaiv tsev tsis ua haujlwm ua rau tam sim no xau rau hauv av (lub ntiaj teb txhaum), qhov rov qab tam sim no hla CBCT core. Qhov no tsim qhov seem tam sim no (zero-ib ntu tam sim no). Qhov tsis sib xws ua rau muaj qhov sib nqus sib nqus hauv lub toroidal core, inducing ib nrab tam sim no. Cov teeb liab no raug xa mus rau Lub Ntiaj Teb Fault Relay (EFR), uas pib qhov kev sib tw tripping.

📐 Daim Ntawv Ceeb Toom Ua Raws: FULLSTAR CBCTs yog tsim thiab sim ua raws li IEC 60044-1 thiab IEC 61869-2 cov qauv, ua kom ntseeg tau tias kev ua tau zoo hauv kev ua txhaum cai.

 

CBCT siv rau dab tsi? (Key Applications)
CBCTs yog qhov tseem ceeb hauv cov tshuab hluav taws xob niaj hnub no. Lawv lub siab rhiab heev rau cov dej ntws uas seem ua rau lawv haum rau cov ntawv thov tseem ceeb hauv qab no:

1. Ntiaj teb Fault Protection (Piv txwv)
CBCTs yog lub hauv paus tseem ceeb ntawm kev nkag siab hauv siab -kev tiv thaiv thiab qis- ua haujlwm hauv av. Lawv ntes cov dej xau tsawg li 30mA txog 5A, ua kom muaj kev sib cais ceev ceev.

 

2. Kev tiv thaiv lub cev muaj zog
Tiv thaiv nruab nrab thiab siab -voltage motor windings los ntawm stator hauv av faults. Txhua theem conductors dhau los ntawm CBCT, kom ntseeg tau tias tsuas yog qhov txhaum tam sim no ua rau muaj kev tiv thaiv.

 

3. Kev tiv thaiv kev hloov pauv
Tiv thaiv transformer tso tsheb hlau luam thiab windings los ntawm lub ntiaj teb ua txhaum, tiv thaiv kev puas tsuaj puas tsuaj los ntawm kev puas tsuaj thiab kev poob qis.

 

4. Cable Feeder tiv thaiv
Nruab ib ncig ntawm cable feeders los muab kev tiv thaiv kev ua txhaum hauv ntiaj teb. Tsuas yog faulty feeder mus txawv tebchaws, tswj fais fab mov mus rau tus so ntawm lub network.

 

5. Switchgear & MCC Vaj Huam Sib Luag
Ua kom cov neeg ua haujlwm muaj kev nyab xeeb thiab cov khoom siv ncaj ncees nyob rau hauv industrial switchgear thiab Motor Control Centers (MCCs).

 

6. Cov Kev Lag Luam Tshwj Xeeb

• Data Centers: Tiv thaiv IT rhiab loads los ntawm cov dej xau.
• Lub zog tauj dua tshiab (hnub ci / cua): Pom DC- sab thiab AC- sab hauv av ua txhaum.
• Mining & Kev Lag Luam Hnyav: Ib puag ncig hnyav hnyav xav tau siab -rhiab heev, rugged CBCT designs.

 

CBCT vs Normal CT: Qhov txawv ntawm qhov tseem ceeb
Ib qho yuam kev feem ntau yog siv tus qauv CT rau kev kuaj xyuas lub ntiaj teb. Nov yog qhov kev sib piv tseem ceeb:

Feature	Pauv CT	CBCT (Core Balance CT)
Lub Hom Phiaj	Phase tam sim no ntsuas / Overcurrent tiv thaiv	Lub ntiaj teb fault & residual tam sim no nrhiav tau
Kev Ntsuas Object	Tus kheej theem tam sim no	Residual / Zero- ntu ntu tam sim no
Conductor Teeb	Ib tug conductor rau ib tug core	Txhua theem conductors dhau los ntawm tib lub hauv paus
Core Structure	Ib tug thawj tig (busbar / cable)	Toroidal core encircling tag nrho cov nyob conductors
Kev tiv thaiv Scope	Tshaj dhau & luv -circuit	Leakage & Av faults (siab rhiab heev)
Nqi Efficiency	Txheem tus nqi	Tus nqi siab dua vim muaj kev tiv thaiv tshwj xeeb

💡 Tswv yim Engineering: Tsis txhob hloov CBCT nrog tus qauv CT rau kev tiv thaiv kev ua txhaum hauv av - qhov kev xav tau thiab kev teeb tsa yog qhov sib txawv.

 

CBCT Cov Txheej Txheem Txhim Kho
Kev txhim kho kom raug yog qhov tseem ceeb rau kev nrhiav kom raug. Ua raws li cov kev coj ua zoo tshaj plaws engineering:

• Conductor Routing: Tag nrho peb theem conductors (thiab nruab nrab, yog tias tsim nyog) yuav tsum dhau qhov nruab nrab ntawm CBCT aperture.
• Tsis suav nrog Lub Ntiaj Teb (Ground) Tus Cwj Pwm: Lub ntiaj teb tiv thaiv (PE) tus neeg xyuas pib yuav tsum tsis txhob hla CBCT. Ua li no yuav tshem tawm qhov teeb meem tam sim no.
• Kev Ruaj Ntseg Cable: Xyuas kom cov cables ruaj ntseg ruaj ruaj los tiv thaiv kev txav mus los uas yuav ua rau kev nyeem ntawv tsis tseeb vim kev ntxhov siab ntawm cov neeg kho tshuab.
• Relay Matching: CBCT cov thawj coj thib ob yuav tsum tau txuas nrog lub ntiaj teb Fault Relay (EFR). Xyuas kom lub nra relay (VA) phim CBCT specification.
• Kev Tiv Thaiv Kev Tiv Thaiv: Khaws cov hlua txuas txuas txuas txuas ntxiv thiab tiv thaiv kom tsis txhob muaj hluav taws xob cuam tshuam los ntawm cov tsheb npav nyob ze.

  

Yuav Ua Li Cas Xaiv Txoj Cai CBCT? (Cov Lus Qhia Xaiv)
Kev xaiv CBCT txoj cai ua kom muaj kev tiv thaiv zoo thiab tus nqi - ua haujlwm tau zoo. Txawm hais tias koj yog ib tus kws tshaj lij qhia cov khoom siv lossis tus tub ceev xwm nrhiav kev hloov pauv CBCT, xav txog 5 qhov tseem ceeb no:
