Thaum nqis peev hauv ib transformer, koj tsis yog cia li yuav khoom siv - koj yuav tau yuav lawm ntau caum lub zog kis tau. Ntawm [koj lub tuam txhab npe], txhua transformer intergoes strigorous zoo checks los ntawm {} tseem ceeb tshaj plaws ua ntej xa khoom. Ntawm no yog ib qho sab hauv ntawm peb cov txheej txheem kev xeem:
1. Wining Kuj Xeem
Lub hom phiaj: Pom cov hluav taws xob hluav taws xob kev ncaj ncees
Siv precision micro-OHM metres, peb ntsuas DC kev tiv thaiv nyob rau hauv tag nrho cov kais txoj haujlwm los xyuas cov kev sib txuas lossis cov khoom tsis xws luag. Qhov no ua kom pom tseeb qhov kev pom zoo tam sim no thiab tiv thaiv cov pob kub.
2. Tig tus piv (TTR)
Lub hom phiaj: Lees paub cov hluav taws xob hloov pauv
Peb lub tshuab ttr sib piv sib piv thawj thiab theem nrab cua sib piv nrog kev ua yuam kev, lav tau koj transformer muab raws li cov voltage uas xav tau.
3. Inurvation Zov Zog Siv Tau
Kev ntsuam xyuas muaj:
Dielectric kev ntsuam xyuas: 50KV AC rau 1 feeb (tshaj IEC 60076 Cov Qauv)
Kev Ua Haujlwm Ncaws Pob: Ntsuas rwb thaiv tsev ua haujlwm
Kev Tso Tawm Ib nrab: <5pC at 1.5x rated voltage
Cov no ua kom koj lub transformer tuaj yeem tiv taus voltage spikes thiab chaw hnyav.
4. Load poob & imgedance ntsuas
Kev siv sim cov kev sim luv, peb:
✓ Xam cov qe plab
Txheeb xyuas cov txiaj ntsig kev cuam tshuam (± 5% kam rau)
✓ Daim ntawv qhia curves
Cov ntaub ntawv no ncaj qha cuam tshuam koj cov nqi zog ntev.
5. Tsis muaj kev sim ua haujlwm
Peb 3-} pege zog poweral analalyzers ntsuas kev poob ntawm ntau voltages, lees tias tias:
Kev nqus cov hluav taws xob ua kom zoo
✔ Cov rooj sib txoos tseem ceeb tau raws li kev tsim qauv
✔ Cov hluav taws xob tau noj nyob hauv tsis pub dhau kev lees paub
6. Qhov kub nce siab
Transformers yauv 12-} teev ua haujlwm tas mus li ntawm 110% load thaum peb:
Saib xyuas roj \/ cua ntxiab nrog cov koob yees duab infrared
Txheeb xyuas txias txias kev ua haujlwm
Xyuas kom txhua tus Cheebtsam nyob hauv qab qhov ntsuas kub tseem ceeb
7. Xob laim ntsuas
Peb simulate-rooj plaub fab xwm txheej uas siv 1.2 \/ 50μs impulse vuag rau:
➤ Ntsuam xyuas Rwb Thaiv Tsev Tawm Tsam
➤ Siv tau xob laim ceem
➤ Ua kom ntseeg tau Surge Kev Tiv Thaiv Kev Tiv Thaiv
8. Cov Lus Qhia Txog Qib
Kuaj nyob rau hauv peb lub Chamber anchhoic rau ib IEEE C57.12.90:
65db ntau rau kev faib khoom xa tuaj
75DB Ntau Ntau rau Cov Hloov Hluav Taws Xob
9. Cov roj zoo kev lees paub (cov roj-cov khoom siv tawm)
Txhua cov roj piv txwv tsis txaus:
Deatolved Roj Kev Tshawb Xyuas (DGA)
Breakdown Voltage Test (>30KV)
Cov ntsiab lus ya raws (<20ppm)
Acidity ntsuas (<0.1mg KOH/g)
10. Tiv Thaiv Cov Ntaus Ntaus
Txhua tus tswj cov tshuab yog kev ntxhov siab:
✔ Buchholz relay taug kev sib txawv
✔ Kev Tshawb Xyuas Kev Tshawb Xyuas Kev Tshawb Nrhiav Kev Tshawb Nrhiav Kev Tshawb Nrhiav Kev Tshawb Nrhiav
O ODTC LUB CAV TAWM TES (10, 000+} Cov Haujlwm)
Vim li cas peb qhov kev sim siab
Peb Lub Chaw Kuaj Xyuas Lub Hoobkas muab:
20+} xyoo ua haujlwm warranty
Daim Ntawv Qhia Ua Raws
Kev kwv yees txij nkawm
