IsiHlalutyi seMpendulo yoMguqulo we-GDRB-B
I-Power transformer winding deformation tester (indlela yokuphendula ngokuphindaphindiweyo) isekelwe kumlinganiselo wemilinganiselo yeempawu ze-transformer yangaphakathi, ithatha i-internal fault frequency analysis analysis (FRA), inokugweba ngokuchanekileyo iimpazamo zangaphakathi ze-transformers.
Emva kokugqitywa koyilo kunye nokuveliswa kweenguqu, iikhoyili kunye nesakhiwo sangaphakathi sigqitywe, ngoko ke i-coil ye-multi-winding transformer, ukuba inqanaba le-voltage kunye nendlela yokuphefumula iyafana, iiparamitha ezihambelanayo (Ci, Li) nganye. ikhoyili iya kumiselwa.Ke ngoko, ukuphendulwa kweempawu zokuphindaphinda kwekhoyili nganye nako kuya kumiselwa, ngoko ke iifrikhwensi zeekhoyili ezihambelanayo zezigaba ezithathu ziyathelekiseka.
Ngexesha lovavanyo lwe-transformer, kwimeko ye-inter-turn, i-inter-phase short circuit, okanye i-coil displacement ebangelwa kukungqubana ngexesha lothutho, kunye nokuguqulwa kwekhoyili okubangelwa kuxinzelelo lwe-electromagnetic ngexesha lokusebenza phantsi kweemeko ezimfutshane kunye neempazamo, iiparamitha zokusabalalisa. ye-transformer windings iya kutshintsha, nto leyo echaphazela kwaye itshintshe iimpawu ze-domain ye-frequency ye-transformer yokuqala, ezizezi utshintsho lwempendulo yefrikhwensi kubukhulu kunye nokutshintsha kwamanqaku amaza.Umvavanyi we-transformer winding ophuhliswe ngokwendlela yokuhlalutya impendulo yinoveli yesixhobo se-NDT sokubona impazamo yangaphakathi ye-transformer.Isebenza ekubhaqweni kwempazamo yesakhiwo sangaphakathi kwiziguquli zamandla ezingama-63kV-500kV.
Umvavanyi woguqulo loguqulo lokujija kukumisela iqondo lotshintsho kwi-windings yangaphakathi ye-transformer esekelwe kubuninzi benguqu, ubukhulu kunye nommandla ochaphazela utshintsho kunye nokuthambekela kwenguqu yempendulo ye-frequency ebalwa ukusuka kwiinguqu zempendulo kwimimandla eyahlukeneyo yamafrikhwensi yokuguquka kwangaphakathi kwe-transformer. iparameters, kwaye ke inokunceda ukufumanisa ukuba i-transformer yonakaliswe kakhulu, okanye idinga ukulungiswa okukhulu ngokuhambelana neziphumo zokulinganisa.
Kwi-transformer esebenzayo, kungakhathaliseki ukuba umzobo we-domain ye-frequency character igcinwa, ngokuthelekisa ulwahlulo phakathi kwe-inter-coil character spectra ye-faulted transformer, inokugqiba ubungakanani bokusilela ngokunjalo.Ngokuqinisekileyo, ukuba ulondoloze i-original transformer windings feature drawings, kuya kuba lula ukubonelela ngesiseko esichanekileyo seemeko zokusebenza, uhlalutyo lwe-post-fault kunye nokulungiswa kokugcinwa kwe-transformer.
Umvavanyi wokuguqula i-deformation ye-Transformer iqulunqwe yikhompyutheni yekhompyutheni kunye nomlawuli omncinci owenza inkqubo yokulinganisa echanekileyo kunye nesakhiwo esihlangeneyo, ukusebenza okulula, kunye nomsebenzi wohlalutyo olupheleleyo olupheleleyo, olunokuthi luqhutywe ngokubhekisele kwincwadana yemiyalelo okanye ngoqeqesho lwexesha elifutshane.
