Phau Ntawv Qhia Beginner rau kev sim cov txheej txheem ntawm tam sim no transformer

Tam sim no transformers (CT) yog ib qho tseem ceeb tshaj plaws nyob rau hauv lub hwj chim systems raws li lawv muab ib tug txhais tau tias ntawm kev ntsuas hluav taws xob tam sim no. Txhawm rau kom ntseeg tau tias CTs ua haujlwm raws li qhov xav tau, lawv yuav tsum tau ua cov txheej txheem kuaj xyuas uas pab tsim kom muaj qhov tseeb, kev ntseeg siab, thiab kev nyab xeeb. Nyob rau hauv tsab xov xwm no, peb tshawb nrhiav cov txheej txheem kev ntsuam xyuas koom nrog hauv kev sim cov transformers tam sim no.

Nkag mus rau qhov ntsuas phaj cov ntaub ntawv hauv daim ntawv xeem thiab sib piv cov ntaub ntawv tam sim no transformer nrog cov ntaub ntawv muaj nyob rau hauv cov ntaub ntawv Circuit Court. Qhov kev xeem hauv qab no yuav tsum tau ua.

1. CT Winding rwb thaiv tsev Resistance test

2. CT Ratio xeem los ntawm kev txhaj tshuaj thawj zaug

ib. CT Ratio

b. Phase Angle yuam kev

3. CT Winding Resistance Ntsuas

4. CT Loop Resistance Measurement

5. CT Polarity Test

6. CT Burden xeem

7. CT Magnetizing Current Test (Knee Voltage test)

8. Demagnetizing CT cores tom qab saum toj no tag nrho cov kev xeem

9. Inter Core coupling Test rau kev kuaj tsheb npav sib txawv

10. High voltage xeem

11. Txheeb xyuas cov kab hluav taws xob theem nrab, cov davhlau ya nyob twg, luv luv / cais cov txuas los ntawm thawj

txhaj tshuaj

12. ib qho point earthing check

13. kev txheeb xyuas theem

Nws yog ib qho tseem ceeb los ua cov kev ntsuam xyuas no tsis tu ncua, tshwj xeeb tshaj yog tom qab kev kho, kho, lossis kev teeb tsa ntawm CTs. Kev kuaj xyuas kom ntseeg tau tias CTs raug teeb tsa, txuas nrog, thiab ntsuas qhov tseeb, yog li txhim kho kev nyab xeeb thiab kev ua haujlwm ntawm lub zog hluav taws xob. Wuhan Huayi fais fab fais fab tshuab tsim thiab ua CT analyzer, uas muaj cov qauv sib txawv thiab kev ua haujlwm, uas tuaj yeem ua tau raws li koj cov kev xav tau. Kev ua haujlwm yog muaj zog, kev ua haujlwm ruaj khov, thiab cov txiaj ntsig kev xeem yog qhov tseeb.
