Ukuguquguquka kwendawo kusho ukuthi ubude bekhoyili buphelele abukashintshi, noma ububanzi obulinganayo nobugqila bekhoyili abushintshile endaweni enkulu;kuphela ukufana kokusabalalisa usayizi kwamanye amakhoyili okushintshile, noma ububanzi obulinganayo bamanye amakhekhe ekhoyili bushintshile kancane.Isamba se-inductance ngokuyisisekelo asishintshile, ngakho-ke amajika e-spectrum esigaba esinephutha kanye nesigaba esivamile azokweqa endaweni ngayinye yokuphakama kwe-resonance kubhendi yefrikhwensi ephansi.Ngosayizi wendawo yokuguqulwa okuyingxenye, iziqongo ze-resonance ezilandelanayo zizosuswa.
I-HV Hipot GDBR-P Transformer Layisha ukungalayishi kanye nesihloli somthamo
Ukucindezelwa kwendawo kanye nokushintshashintsha kokukhipha: Lolu hlobo lokuguquguquka ngokuvamile lubhekwa njengolubangelwa amandla kazibuthe kagesi.Ngenxa yamandla okujikijela akhiqizwa i-current ngendlela efanayo, lapho amachopho amabili ekhoyili ecindezelwe, la mandla okuxosha azokhama ama-pads ngamanye, okubangela ukuthi Izingxenye ziyampintsha futhi izingxenye zihlukaniswe.Lolu hlobo lwe-deformation ngokuvamile aluthinti intambo yomthofu ngaphansi kwesimo sokuthi izipikili zokucindezela emikhawulweni yomibili azinyakaziswa: lolu hlobo lokuguquguquka ngokuvamile lushintsha kuphela ibanga (i-axial) phakathi kwamakhekhe, futhi amandla (phakathi kwamakhekhe) abonisiwe. ku-inductance ehambisanayo ku-capacitance yesifunda esilinganayo) izinguquko.Njengoba imikhondo ingadonswa, ingxenye yefrikhwensi ephezulu ye-spectrum izoshintsha kancane kakhulu.Ikhoyili yonke ayicindezelwa, ingxenye kuphela yebanga phakathi kwamaqebelengwane ihlukaniswa, futhi amanye amabanga phakathi kwamakhekhe ayacindezelwa.Kungabonakala ku-spectrogram ukuthi ezinye iziqongo ezizwakalayo zihamba ziye endaweni yemvamisa ephezulu ngokuncipha kwenani eliphakeme;kuyilapho ezinye iziqongo ezinomsindo zithuthela endaweni ephansi yemvamisa futhi zihambisana nokwenyuka kwenani eliphakeme.Indawo yokuguquguquka kanye nezinga lokuguquguquka kungalinganiswa futhi kuhlaziywe ngokuqhathanisa indawo lapho ukuphakama kwe-resonance ngokusobala kugudluliwe, (inani leziqongo) kanye nenani lokushintsha kwenani eliphakeme le-resonance.Ingxenye ye-high-frequency ye-spectrogram izoshintsha lapho ukucindezela kwendawo kanye nokukhubazeka kokukhipha kuthinta umkhondo.Lapho izinga lokucindezelwa kwendawo kanye nokuguqulwa kokukhipha lilikhulu, ezinye iziqongo ze-resonance zifinyelela phezulu kumabhendi efrikhwensi aphansi naphakathi, ukuphakama ngakunye kuyanyamalala, futhi ukuphakama kwezinye iziqongo ze-resonance kuyanda.
I-turn-to-turn short circuit: Uma i-metallic inter-turn short circuit yenzeka kwikhoyili, ukudunyiswa kwekhoyili kuzokwehla kakhulu, futhi ukuvimbeka kwekhoyili kusignali kuzokwehla kakhulu.Ngokuhambisana ne-spectrogram, ukuphakama kwe-resonant yebhendi yefrikhwensi ephansi ngokusobala kuzohamba iye kusiqondiso se-frequency ephezulu, futhi ngesikhathi esifanayo, ngenxa yokuncipha kwesithiyo, ijika lokuphendula imvamisa lizoya ohlangothini lokuncipha kokuncipha ibhendi yefrikhwensi ephansi, okungukuthi, ijika lizoya phezulu ngaphezu kuka-2ddB;Ukwengeza, umehluko phakathi kweziqongo ze-resonance nezigodi kujika le-spectrum uzoncishiswa ngenxa yokuncipha kwevelu ye-Q.Amajika e-spectral amabhande aphakathi naphezulu ahambisana nalawo ekhoyili evamile.
Izintambo zekhoyili eziphukile: Lapho izintambo zekhoyili zephukile, ukuguquguquka kwekhoyili kuzokwanda kancane.Ngokuhambisana ne-spectrogram, ukuphakama kwe-resonant yebhendi ye-low-frequency kuzohamba kancane kusiqondiso se-low-frequency, futhi ukunciphisa ku-amplitude kuzohlala kungashintshiwe;ama-spectral curves of the mid-frequency and high-frequency bands ahambisana ne-spectrogram yekhoyili evamile.
Umzimba wangaphandle wensimbi: Kukhoyili evamile, uma kukhona umzimba wangaphandle wensimbi phakathi kwamakhekhe, nakuba unomthelela omncane ku-low frequency total inductance, amandla phakathi kwamakhekhe azokhula.I-resonance peak yengxenye ye-low frequency curve ye-spectrum izothuthela endaweni ephansi ye-frequency, futhi i-amplitude yengxenye ephakathi nendawo ephezulu yejika izokhula.
Ukususwa komthofu: Uma umthofu ususwa, akuthinti i-inductance, ngakho-ke ibhendi yefrikhwensi ephansi yejika le-spectrum kufanele yeqeke ngokuphelele, futhi ijika kuphela engxenyeni engu-2ookHz~5ookHz eguqukayo, ikakhulukazi ngokuya nge-amplitude yokunciphisa.Lapho intambo yomthofu iya ngasegobolondweni, ingxenye yefrikhwensi ephezulu yejika le-spectrum ihamba ibheke lapho kuncipha khona okwandayo, futhi ijika liya phansi;lapho intambo yomthofu isondela eduze kwekhoyili, ingxenye yefrikhwensi ephezulu yejika le-spectrum ihamba ibheke ekuncipheni kokuncipha, futhi ijika liya phezulu.
I-axial buckle: I-axial twist iwukuthi ngaphansi kwesenzo samandla kagesi, ikhoyili iphushela ngaphandle kuyo yomibili imikhawulo.Uma icindezelwa yizo zombili iziphetho, iphoqeleka ukuthi igxumeke phakathi nendawo.Uma igebe lomhlangano we-transformer yasekuqaleni likhulu noma ama-braces aphoqeleka ukuba ashintshe, ikhoyili iphikisiwe ibe yi-S shape ekuqondeni kwe-axial;lokhu kuguqulwa kushintsha kuphela ingxenye ye-capacitance phakathi kwamakhekhe kanye nengxenye ye-capacitance emhlabathini ngoba iziphetho ezimbili azishintshi.Umthamo wesikrini esiphakathi nendawo kanye namandla okuya phansi kuzokwehla, ngakho-ke i-resonant peak izohamba iye kumafrikhwensi aphezulu kujika le-spectrum, i-resonant peak eduze ne-low frequency izokwehla kancane, futhi i-resonant peak frequency eduze ne-intermediate frequency izokhuphuka. kancane, futhi imvamisa ye-3ookHz~5ookHz izokwenyuswa kancane.Imigqa ye-spectral ngokuyisisekelo igcina inkambiso yasekuqaleni.
Ukuguquguquka kwe-amplitude (diameter) yekhoyili: Ngaphansi kwesenzo samandla e-electrodynamic, ikhoyili yangaphakathi ngokuvamile ingena ngaphakathi.Ngenxa yomkhawulo wokuhlala kwangaphakathi, ikhoyili ingase ikhubazeke ekuqondeni kwe-amplitude, futhi umkhawulo wayo uzoba zigzag.Lokhu kuguqulwa kuzokwenza ukuthi i-inductance Yehlise kancane, amandla okuya emhlabathini nawo ashintshe kancane, ngakho-ke ukuphakama kwe-resonance kulo lonke uhla lwamafrikhwensi kuhamba kancane kusiqondiso sefrikhwensi ephezulu.I-deformation ye-amplitude yekhoyili yangaphandle ikakhulukazi ukunwetshwa kwangaphandle, futhi i-inductance ephelele yekhoyili ye-deformation izokhuphuka, kodwa ibanga phakathi kwamakhoyili angaphakathi nangaphandle lizokhula, futhi amandla ekhekhe locingo phansi azokwehla.Ngakho-ke, i-resonance peak yokuqala kanye nesigodi ku-spectrum curve izohamba iye endaweni ephansi ye-frequency, futhi iziqongo ezilandelayo nezigodi zizohamba kancane ziye endaweni ephakeme kakhulu.
