Apo simba remumunda remagetsi rinoshandiswa mumagetsi emagetsi rinokwana kukonzera kubuda munzvimbo yekudzivirira chikamu, asi chiitiko chekubudisa kuti hapana chinogadziriswa chekubuda mugero chinoumbwa munzvimbo yekubuda inonzi chikamu chekubuda.
HV HIPOT GDJF-2007 Digital Partial Discharge Analyzer
Iyo partial discharge tester ine digital partial discharge detector uchishandisa musimboti weiyo pulse ikozvino nzira:
Iyo pulse ikozvino nzira inoreva kuti kana kubuda kwechidimbu kuchiitika, migumo miviri yemuenzaniso Cx inoita pakarepo magetsi kuchinja Δu.Panguva ino, kana iyo Ck yemagetsi yakabatanidzwa kune yekuona impedance Zd, pulse ikozvino ini ndichagadzirwa mudunhu, uye iyo pulse ikozvino inogadzirwa kuburikidza nekuona impedance.Iyo pulse voltage ruzivo inoonekwa, inokwidziridzwa uye kuratidzwa, uye mamwe akakosha maparamita ekubuda kwechidimbu (kunyanya iyo yekuburitsa huwandu q) inogona kutsanangurwa.
Izvo zvinofanirwa kutaurwa pano kuti iyo chaiyo yechikamu kubuda mukati meyedzo chigadzirwa haigone kuyerwa.Nekuti nzira yekufambisa uye kutungamira kwechikamu chekuburitsa pulse mukati mechigadzirwa chebvunzo yakanyanya kuomarara, isu tinongoda kushandisa nzira yekuenzanisa kuona kutaridzika kwechigadzirwa chekuyedza.Muchaji yekuburitsa, ndiko kuti, jekiseni huwandu hwemagetsi kumigumo yese yebvunzo isati yaitwa bvunzo, gadzirisa magnification kuti umise chiyero, uye wozoenzanisa chikamu chekuburitsa pulse mukati meyedzo sampu yakagamuchirwa pasi peiyo chaiyo. voltage nechikero, kuitira kuti uwane Inoratidzika discharge yechinhu chekuedza.
Iyo yedhijitari partial discharge detector inovimbisa kuvimbika kweiyo data yakaonekwa kuburikidza nedhijitari chiratidzo chekugadzirisa, adaptive kusefa uye dzimwe nzira dzekukanganisa dzekugadzirisa zviratidzo.
