Kungani udinga ukwenza i-AC ukumelana nokuhlolwa kwe-voltage emishinini yamandla?Ukuhlolwa kwe-AC ukumelana ne-voltage kuyindlela ephumelelayo neqondile yokuhlonza amandla e-dielectric emishini yamandla.
HV Hipot GDTF uchungechunge Variable Frequency AC Resonance Test System
Ngesikhathi sokusebenza kwemishini yamandla, ukufakwa kuzowohloka kancane kancane ngaphansi kwesenzo sensimu kagesi, izinga lokushisa kanye nokudlidliza komshini isikhathi eside.Inkomishi kawoyela ejwayelekile isetshenziselwa ukuhlolwa kwe-voltage ye-insulating oil ukuze ibambe uwoyela.Lokhu kuhlanganisa ukuwohloka okuphelele nokuwohloka ngokwengxenye, ukwakha amaphutha.Isibonelo, ngenxa yensimu kagesi yendawo igxile kakhulu noma ukufakwa kwendawo kubuthakathaka, kukhona amaphutha wendawo.Izindlela ezihlukahlukene zokuhlola zokuvimbela, ngayinye enamandla ayo, ingathola ukukhubazeka okuthile futhi ibonise isimo sokushisa, kodwa i-voltage yokuhlola yezinye izindlela zokuhlola ivamise ukuba ngaphansi kune-voltage esebenzayo yemishini yamandla, engaqinile ngokwanele njengesiqinisekiso sokuphepha. ukusebenza..
Nakuba i-DC ukumelana nokuhlolwa kwe-voltage iphakeme uma kuqhathaniswa, amanye amaphuzu abuthakathaka okufakelwa angatholakala, kodwa ngenxa yokuthi iningi lokufakwa kwemishini yamandla liyinhlanganisela yama-dielectrics, ngaphansi kwesenzo se-voltage ye-DC, i-voltage isakazwa ngokuvumelana nokumelana, ngakho-ke. I-DC isetshenziselwa ukuhlolwa.Akwenzeki njalo ukuthola ubuthakathaka bempahla yamandla e-AC ngaphansi kwenkundla kagesi ye-AC.Isibonelo, ukukhubazeka kwe-slot ye-generator akulula ukutholakala ngaphansi kwe-DC.
Ukuhlolwa kwe-AC ukumelana ne-voltage kuvumelana nezimo zikagesi izinto zikagesi ezingaphansi kwazo ngesikhathi sokusebenza.Ngesikhathi esifanayo, i-AC ukumelana ne-voltage test voltage ngokuvamile iphezulu kune-voltage yokusebenza.Ngakho-ke, ngemva kokuphumelela ukuhlolwa, imishini inomkhawulo omkhulu wokuphepha, ngakho-ke lokhu kuhlolwa kuye kwaba isiqinisekiso sokuphepha.indlela ebalulekile yokusebenza.Kodwa-ke, ngenxa yokuthi i-voltage yokuhlola esetshenziswa ekuhlolweni kwe-AC ukumelana ne-voltage iphezulu kakhulu kune-voltage yokusebenza, i-voltage eyeqile izokhuphula ukulahleka kwe-insulating medium, ikhiphe ukushisa, ikhiphe, futhi isheshise ukuthuthukiswa kokulimala kokufakwa kwe-insulation.Ngakho-ke, ngomqondo othile, i-AC ukumelana nokuhlolwa kwe-voltage kuwukuhlola okulimazayo.
Ngaphambi kokuthi i-AC imelane nokuhlolwa kwe-voltage, ukuhlolwa okuhlukile okungabhubhisi kufanele kwenziwe kusenesikhathi, njengokulinganisa ukumelana nokufakwa ngaphakathi, isilinganiso sokumuncwa, i-dielectric loss factor tgδ, i-DC yokuvuza yamanje, njll. I-HV Hipot ihlaziya imiphumela yokuhlolwa ukuze inqume ukuthi idivayisi imanzi noma inesici.Uma kutholakala ukuthi kunenkinga, idinga ukusingathwa kusenesikhathi, futhi ukuhlolwa kwe-AC ukumelana ne-voltage kungenziwa ngemuva kokususwa kwesici, ukuze kugwenywe ukuqhekeka kwe-insulation ngesikhathi sokuhlolwa kwe-AC ukumelana nokuhlolwa kwe-voltage, ukwandisa ukwahlukanisa. amaphutha, ukwandisa isikhathi sokulungisa, nokwandisa umthwalo wokulungisa..
