GDRB-B Transformer Frequency Response Analyzer
Power transformer winding deformation tester (mokgwa wa karabelo ya kgafetsa) e ipapisitse le tekanyo ya diparamente tsa sebopeho sa transfoma e ka hare, e amohela mokgwa wa ka hare wa karabelo ya phoso (FRA), e ka ahlolang diphoso tsa ka hare tsa diphetoho ka nepo.
Ka mor'a ho phethoa ha moralo le ho etsoa ha li-transformer, li-coil le sebopeho sa ka hare li phethoa, kahoo bakeng sa coil ea transformer e nang le maqhubu a mangata, haeba boemo ba motlakase le mokhoa oa ho phalla li tšoana, li-parameter tse lumellanang (Ci, Li) tsa e 'ngoe le e 'ngoe. khoele e tla khethoa.Ka hona, karabelo ea litšoaneleho tsa khafetsa tsa coil ka 'ngoe le eona e tla khethoa, ka hona, maqhubu a maqhubu a likhoele tse tsamaellanang tsa mekhahlelo e meraro a ka bapisoa.
Nakong ea tlhahlobo ea transformer, haeba ho e-ba le potoloho e khuts'oane ea li-inter-turn, inter-phase short circuit, kapa ho falla ha coil ho bakoang ke ho thulana nakong ea lipalangoang, hammoho le deformation ea coil e bakoang ke tsitsipano ea motlakase nakong ea ts'ebetso tlas'a potoloho e khutšoanyane le maemo a phoso, litekanyetso tsa kabo. Maqhubu a li-transformer a tla fetoha, 'me ka hona a ama le ho fetola litšoaneleho tsa mantlha tsa li-frequency frequency domain, e leng phetoho ea karabelo ea maqhubu ka boholo le ho fetoha ha lintlha tsa maqhubu a resonant.Teko ea li-transformer winding e ntlafalitsoeng ho latela mokhoa oa tlhahlobo ea karabelo ke sesebelisoa se secha sa NDT sa ho bona phoso ea kahare ea transformer.E sebetsa tabeng ea ho lemoha phoso ea sebopeho sa ka hare ho li-transformer tsa matla a 63kV-500kV.
Transformer winding deformation tester ke ho fumana hore na ho na le liphetoho life tse ka hare ho transformer tse ipapisitseng le boholo ba phetoho, boholo le sebaka se amang phetoho le tšekamelo ea ho fetola karabelo ea maqhubu, e lekantsoeng ho tsoa ho liphetoho tsa karabelo libakeng tse fapaneng tsa maqhubu a kahare a transfoma. parameters, 'me joale e ka thusa ho fumana hore na transformer e senyehile haholo, kapa e hloka phetoho e kholo ho latela liphello tsa tekanyo.
Bakeng sa transformer e sebetsang, ho sa tsotellehe hore na setšoantšo sa "frequency domain characteristic drawing" se bolokiloe, ka ho bapisa phapang pakeng tsa li-inter-coil character spectra ea transformer e fosahetseng, e ka tseba hore na ho hlōleha ho hokae.Ha e le hantle, haeba u bolokile litšoantšo tsa sebopeho sa li-transformer windings tsa pele, ho tla ba bonolo ho fana ka motheo o nepahetseng oa maemo a ts'ebetso, tlhahlobo ea morao-rao le ho lokisoa ha phetoho ea transformer.
Transformer winding deformation tester e entsoe ke komporo ea laptop le micro controller e etsang sistimi ea tekanyo e nepahetseng e nang le sebopeho se kopaneng, ts'ebetso e bonolo, e nang le ts'ebetso e felletseng ea tlhahlobo ea liteko, e ka sebetsoang ho latela bukana ea litaelo kapa ka koetliso ea nako e khuts'oane.
