I-frequency AC resonant test system isetshenziselwa ukukhomba amandla okufakwa kwezinto zikagesi.Kubaluleke kakhulu ukwahlulela ukuthi impahla kagesi ingaqala ukusebenza.Futhi kuyindlela ebalulekile yokuqinisekisa izinga lokufakwa kwemishini futhi ugweme izingozi zokufakelwa.Ngenxa yokuthi idivayisi yokuhlola i-resonance yochungechunge lokuguqulwa kwemvamisa ingabonisa ngokugcwele isimo sangempela sezinto zikagesi ezisebenza ngaphansi kwamandla kagesi we-AC, ingathola ngempela futhi ngempumelelo ukonakala kokufakwa.
Uchungechunge lwe-HV HIPOT GDTF lwe-Frequency Conversion AC Resonant Test System
Ngenxa yesimiso se-resonance esamukelwe idivayisi yokuhlola i-resonance yochungechunge lokuguqulwa kwemvamisa, i-voltage yefrikhwensi ethile kuluphu yesistimu kanye namandla nokusabela kuluphu kukhiqiza ukuzwakala.I-voltage ngaphesheya kwe-capacitor ifinyelela ku-voltage yokuhlola.
Ngokwalezi zimiso ezingenhla kanye nesimo sangempela sokuhlola esizeni, ukugcwala ngokweqile kochungechunge lokuguqulwa kwemvamisa ye-resonance ngokuvamile kwenzeka ezimeni ezimbili, esisodwa yilapho ithuluzi lifuna indawo ye-resonance kanye nenqubo yokukhiqiza i-resonance voltage;enye yilapho i-boost voltage ifinyelela ku-voltage yokuhlola.uma kwenzeka kuba.
Esimeni sokuthola iphoyinti le-resonance kuchungechunge lwe-resonance futhi ulikhulise ku-voltage yokuhlola, ngokuvamile esimweni lapho i-voltage ye-standard yomkhiqizo wokuhlola ingafaneleki noma indawo yesayithi ayizange ibe nezinguquko ezinkulu, ukuhlolwa ngeke kukhiqize ukuvikeleka kwe-overvoltage. noma amanye amaphutha.Kodwa-ke, njengoba i-voltage yegridi ingashintshi futhi i-voltage yokufaka yokuphakelwa kwamandla ishintshashintsha, ukuphuma kwe-high-voltage nakho kuba nokuguquguquka okuthile, okungase kubangele ukuvikelwa kwe-overvoltage esiqongweni se-voltage.Uma i-voltage yokunikezwa kwamandla iguquguquka, ungalungisa ukuvikelwa kwe-overvoltage yethuluzi, futhi usethe ukuvikelwa kwe-overvoltage kunani eliphezulu ngokuqhathaniswa.Ngokuvamile sidinga ukuthi ukuvikelwa kwe-overvoltage kusethelwe ku-1.1-1.2 izikhathi zokuvikela i-voltage.Ngalesi sikhathi, empeleni akuyona inkinga ukusethela izikhathi ezingu-1.2.
Lokhu okungenhla kuyinkinga elula, kodwa kunzima ngokuguquguquka kwamandla kagesi ukuthi kubangele ukuthi kuvele u-overvoltage uma ukuvikelwa kwe-overvoltage kusethiwe.Ngokuvamile, ukugcwala ngokweqile kwedivayisi yokuhlola i-resonance yochungechunge lokuguqulwa kwemvamisa kusesigabeni sokushanela imvamisa yensimbi, okusho ukuthi, kuyinqubo yokuthola iphuzu le-resonance.Noma ubani osebenzise idivayisi yokuhlola i-resonance yochungechunge lokuguqulwa kwe-frequency uyazi ukuthi ngesikhathi sokuthola iphoyinti le-resonance yedivayisi yokuhlola i-resonance yochungechunge lokuguqulwa kwe-frequency, i-voltage ne-frequency inobudlelwano obufanayo bomugqa njenge-parabola.Ngokuzenzakalelayo, isistimu ithola i-voltage ephakeme, okungukuthi, i-vertex ye-parabola, njengephoyinti le-resonance.Njengoba ithiyori yesimiso se-resonance ikwazi ukwenza kabusha i-voltage ephansi ibe izikhathi ezingu-80 (ngenxa yesici sekhwalithi nobunye ubudlelwano ngokuvamile obungadluli izikhathi ezingu-30), i-voltage edingekayo ukuze kushanelwe imvamisa yochungechunge lokuguqula imvamisa idivayisi yokuhlola i-resonance ngokuvamile iba ngama-20. -50V, futhi i-voltage ngemva kokuvuswa ngokuvamile ingamakhulu amaningana ama-volts.Ngokusebenzisa lezi zimiso ezingenhla, sithole ukuthi uma i-voltage yokuhlola yomkhiqizo wokuhlola esiyidingayo ingaphansi kwe-voltage lapho i-resonance yesistimu iyiphoyinti le-resonance, isistimu ingase ibe nokuvikelwa kwe-overvoltage uma icinga ngokuzenzakalelayo iphuzu le-resonance.Ngalesi sikhathi, yonke idivayisi yokuhlola i-variable frequency series ayikwazi ukumelana nokucindezela, ukuhlolwa akukwazanga ukuqedwa.
Isixazululo sale nkinga sibuye sibe nzima.Akukhona ukuthi idivayisi yokuhlola i-resonance yochungechunge oluguquguqukayo ayikwazi ukukhiqiza i-voltage yokuhlola, kodwa i-voltage ye-resonance iphakeme kune-voltage yokuhlola.Siyazi ukuthi i-voltage ye-resonance ezenzakalelayo yesistimu iyi-vertex ye-parabola, okusho ukuthi, lapho i-parabola ikhuphuka ukuya Enkambisweni ye-vertex noma i-vertex yehla, kuzoba nephuzu elihambisana nephuzu lokuhlola le-voltage.Sidinga kuphela ukuhlola ukuhlolwa okwenziwa ngesandla kwe-resonance yochungechunge lokuguqulwa kwe-frequency, futhi sisebenzise usesho lwamafrikhwensi okwenziwa ngesandla ukuze sithole iphoyinti lefrikhwensi ehambisana ne-voltage esetshenzisiwe bese simelana ne-voltage ukuze sixazulule inkinga ye-overvoltage ohlelweni lokuthola indawo ye-resonance.
