Hom ntsuas twg ua qhov kev xeem SFRA, thiab cov yam ntxwv dab tsi uas tus kws ua haujlwm yuav tsum nrhiav?
Ib qho kev xeem SFRA yog ib qho tshwj xeeb ob -chaw nres nkoj network analyzer. RBX-H tester ntsuas lub windings 'tus yam ntxwv tsis nyob rau hauv lub transformer, siv lub suab sab hauv fault zaus teb tshuaj ntsuam xyuas (FRA) txoj kev tsim nyob rau hauv lub ntiaj teb no- cov teb chaws ua, ua kom raug kev txiav txim siab ntawm internal transformer faults. SFRA tester muaj lub laptop thiab nti microprocessor precision ntsuas tshuab, compact, yooj yim rau kev khiav lag luam, nrog rau kev ntsuam xyuas kev ua haujlwm.

Parameter |
Pom zoo Range |
Vim Li Cas Nws Tseem Ceeb |
|
Ntau zaus |
10 Hz - 2 MHz (min) |
Npog core, winding, thiab lead cheeb tsam |
|
Dynamic ntau yam |
>100 dB |
Xyuas kom rhiab heev nyob rau hauv tag nrho cov bands |
|
Cov zis impedance |
50 Ω (coaxial) |
Txheem rau kev sib txuas ua ke |
|
Sweep cov ntsiab lus |
Ntau tshaj los yog sib npaug rau 1000 (log spacing) |
Kev daws teeb meem tsim nyog rau kev tshawb nrhiav pom |
|
Kev ntsuas qhov tseeb |
± 0.5 dB mag, ± 1℃theem |
Txhim khu kev qha inter -theem kev sib piv |
|
Port configuration |
2-chaw nres nkoj ( kis tau tus mob + reflection) |
Tag nrho characterization muaj peev xwm |
Daim ntawv teev cov khoom siv tswv yim:
• Coaxial test leads (10 m, 15 m, 20 m sets)
• Alligator-rau-BNC adapters rau bushing terminals
• Cov khoom siv sib txuas hauv av
• Kev ntsuas kub / av noo (rau cov ntaub ntawv traceability)
• Software rau correlation coefficient tsom xam thiab qhia tsim
Pro tswv yim:Nco ntsoov xyuas kom meej tias qhov input impedance ntawm lub ntsuas ntsuas qhov impedance ntawm coaxial cables. A 50 Ω mismatch qhia sawv cev-wave artifacts saum 500 kHz, ua rau tsis tseeb "deformation" indications.
