Dab tsi yog qhov transformer winding deformation xeem?
Transformer winding deformation testing yog ib txoj kev tshawb nrhiav uas tshuaj xyuas cov kev hloov hauv hluav taws xob, xws li inductance, capacitance, thiab impedance ntawm winding, los txiav txim seb lub winding puas tau undergone axial / radial displacement, distortion, los yog bulging. Cov deformations no feem ntau yog tshwm sim los ntawm luv luv - cuam tshuam hauv Circuit Court, kev vibrations kev thauj mus los, thiab overheating aging, thiab lawv yuav cuam tshuam ncaj qha rau cov rwb thaiv tsev kev ua tau zoo thiab kev ua haujlwm ruaj khov ntawm lub transformer.
Puas yog SFRA tsom xam txoj hauv kev yog thawj txoj hauv kev los ua cov kev sim hloov pauv winding deformation?

Txoj Kev Tshawb Fawb Txog Kev Tshawb Fawb (FRA)
Lub hauv paus ntsiab lus: Txha qhov dav -band teeb liab mus rau hauv lub winding, sau lub amplitude-frequency/phase- zaus teb curves ntawm winding, thiab muab piv nrog cov qub nkhaus los yog nkhaus ntawm tib hom transformer. Los ntawm qhov sib xws, qhov℃ntawm deformation tuaj yeem txiav txim siab.
Qhov zoo: siab rhiab heev, muaj peev xwm ntes micrometer-qib deformation, haum rau transformers ntawm txhua theem voltage.
Cov txheej txheem txiav txim: Raws li DL/T 911-2016 tus qauv, siv cov coefficients sib raug zoo, qhov sib txawv ntawm qhov sib txawv, thiab lwm yam, los ntsuas qhov sib txawv nkhaus. Cov deformations no feem ntau tshwm sim los ntawm kev cuam tshuam luv luv, kev vibrations kev thauj mus los, thiab overheating aging, thiab yuav cuam tshuam ncaj qha rau lub rwb thaiv tsev kev ua tau zoo thiab kev ua haujlwm ruaj khov ntawm lub transformer.
