Ukuguqulwa kwendawo kuthetha ukuba ubude obupheleleyo bekhoyili abuguqukanga, okanye ububanzi obulinganayo kunye nobukhulu bekhoyili abutshintshanga kwindawo enkulu;kuphela ukufana kokuhanjiswa kobungakanani kwezinye iikhoyili zitshintshile, okanye i-diameter elinganayo yezinye iikeyiki zekhoyili itshintshile kumlinganiselo omncinci.I-inductance iyonke ayitshintshi ngokusisiseko, ngoko ke i-spectrum curves yesigaba esiphosakeleyo kunye nesigaba esiqhelekileyo siya kukhwelana kwindawo nganye ye-resonance peak point kwi-low frequency band.Ngobungakanani bendawo yokuguqulwa kwenxalenye, iincopho ze-resonance ezihambelanayo ezilandelayo ziya kususwa.

Uxinzelelo lwasekhaya kunye noguquko oluphumayo: Olu hlobo lwenguquko luthathwa ngokuba lubangelwa ngamandla ombane.Ngenxa amandla repulsion eveliswa lwangoku kwicala elinye, xa iziphelo ezibini coil zixinaniswe, lo mkhosi repulsion uya kukhama ngaphandle pads ngamnye, kubangela Parts zicudiwe kwaye iinxalenye zitsalwa ngaphandle.Olu hlobo lokuguqulwa ngokubanzi aluchaphazeli ucingo olukhokelayo phantsi kwemeko yokuba izikhonkwane zoxinzelelo kuzo zombini iziphelo azishukunyiswa: olu hlobo lokuguqulwa ngokubanzi lutshintsha kuphela umgama (i-axial) phakathi kweekeyiki, kunye ne-capacitance (phakathi kweekeyiki) kwi-parallel inductance kwi-capacitance yesekethe elinganayo) utshintsho.Ngezikhokelo ezingatsalwanga, isahlulo esiphezulu se-spectrum siya kutshintsha kancinane kakhulu.Ikhoyili yonke ayixinzelelwanga, inxalenye kuphela yomgama phakathi kweekeyiki itsalwa ngaphandle, kwaye eminye imigama phakathi kweekeyiki zixinzelelwe.Inokubonwa kwi-spectrogram ukuba ezinye iincopho ze-resonant zihamba kwi-high frequency direction kunye nokuncipha kwexabiso eliphezulu;ngelixa ezinye iincopho ze-resonant zihamba ukuya kwi-low frequency direction kwaye zihamba kunye nokunyuka kwexabiso eliphezulu.Ummandla we-deformation kunye neqondo le-deformation inokuqikelelwa kwaye ihlalutywe ngokuthelekisa indawo apho i-resonance peak iguqulwa ngokucacileyo, (inani leencopho) kunye nenani lokutshintsha kwe-resonance peak.Inxalenye ye-high-frequency ye-spectrogram iya kutshintsha xa ukunyanzeliswa kwendawo kunye nokukhupha i-deformations kuchaphazela izikhokelo.Xa iqondo loxinzelelo lwengingqi kunye nokutsalwa-ngaphandle deformation inkulu, ezinye iincopho resonance kwi-frequency ephantsi kunye ne-middle frequency bands overlap, iincopho ngamnye shwaka, kwaye amplitude ezinye iincopho resonance ukwanda.
Ukuguqula isiphaluka esifutshane: Ukuba i-metallic inter-turn short circuit iyenzeka kwi-coil, i-inductance iyonke yekhoyili iya kuncitshiswa kakhulu, kwaye ukuvinjelwa kwekhoyili kwisignali kuya kuncitshiswa kakhulu.Ngokuhambelana ne-spectrogram, incopho ye-resonant ye-low frequency band iya kuhamba ngokucacileyo ukuya kwi-high frequency direction, kwaye kwangaxeshanye, ngenxa yokuncipha komqobo, ijika lokuphendula i-frequency liza kuhambela kwicala lokunciphisa ukuthomalalisa kwindawo. ibhendi yefrikhwensi ephantsi, oko kukuthi, igophe liya kunyukela phezulu ngaphezu kwe-2ddB;Ukongezelela, umahluko phakathi kweencopho ze-resonance kunye neentlambo kwi-curve spectrum ziya kuncitshiswa ngenxa yokuncipha kwexabiso le-Q.I-spectral curves ye-mid and high frequency bands ihambelana naleyo yekhoyili eqhelekileyo.
Iintambo zekhoyili ezaphukileyo: Xa iintambo zekhoyili ziphukile, i-inductance iyonke yekhoyili iya kwanda kancinci.Ngokuhambelana ne-spectrogram, i-resonant peak ye-low-frequency band iya kuhamba kancane ukuya kwi-low-frequency direction, kwaye i-attenuation kwi-amplitude iya kuhlala ingatshintshi;i-spectral curves ye-middle-frequency kunye ne-high-frequency bands ihambelana ne-spectrogram yekhoyili eqhelekileyo.
Umzimba weMetal wangaphandle: Kwikhoyili eqhelekileyo, ukuba kukho umzimba wesinyithi wangaphandle phakathi kwamaqebelengwane, nangona unempembelelo encinci kwi-inductance ephantsi rhoqo, i-capacitance phakathi kwamaqebelengwane aya kwanda.Incopho ye-resonance ye-low frequency part ye-curve spectrum iya kuhamba ukuya kwi-low frequency direction, kwaye i-amplitude ye-middle and high frequency part of the curve iya kwanda.
Ukufuduka okukhokelayo: Xa i-lead isuswa, ayichaphazeli i-inductance, ngoko ke i-band frequency ephantsi ye-curve ye-spectrum kufuneka igqitywe ngokupheleleyo, kwaye kuphela i-curve kwi-2ookHz ~ 5ookHz inxalenye yenguqu, ngokukodwa ngokubhekiselele kwi-amplitude yokunciphisa.Xa ucingo olukhokelayo lusiya kwiqokobhe, indawo ephezulu ye-spectrum curve ishukuma kwicala lokunyusa ukuncipha, kwaye igophe lihlehlela ezantsi;xa ucingo olukhokelayo lusondela kufutshane nekhoyili, inxalenye ephezulu yefrikhwensi ye-spectrum curve ihamba kwicala lokunciphisa ukuthotywa, kwaye i-curve ihambela phezulu.
I-Axial buckle: I-Axial twist kukuba phantsi kwesenzo samandla ombane, ikhoyili ikhutshelwa ngaphandle kuzo zombini iziphelo.Xa icinezelwe ngeziphelo zombini, kunyanzeleke ukuba ikhubazeke ukusuka embindini.Ukuba i-gap yendibano ye-transformer yasekuqaleni inkulu okanye i-braces inyanzelekile ukuba itshintshe, i-coil iguqulwe ibe yi-S shape kwi-axial direction;le deformation itshintsha kuphela inxalenye ye-capacitance phakathi kweekeyiki kunye nenxalenye ye-capacitance emhlabeni ngenxa yokuba iziphelo ezimbini azitshintshi.I-inter-screen capacitance kunye ne-capacitance emhlabeni iya kuncipha, ngoko ke i-resonant incopho iya kuhamba iye kwi-frequency ephezulu kwi-curve ye-spectrum, i-resonant peak kufuphi ne-low frequency iya kuhla kancinci, kunye ne-resonant peak frequency kufuphi ne-intermediate frequency iya kunyuka. kancinci, kwaye ukuphindaphinda kwe-3ookHz ~ 5ookHz kuya kwandiswa kancinci.Imigca ye-spectral igcina ngokusisiseko isiqhelo sokuqala.
I-Amplitude (i-diameter) deformation yekhoyili: Ngaphantsi kwesenzo samandla e-electrodynamic, i-coil yangaphakathi ibanjwe ngokubanzi ngaphakathi.Ngenxa yokukhawulelana kokuhlala kwangaphakathi, i-coil inokukhubazeka kwindlela ye-amplitude, kwaye umda wayo uya kuba zigzag.Olu tshintsho luya kwenza i-inductance iNciphise kancinci, i-capacitance emhlabeni iphinda itshintshe kancinane, ngoko ke i-resonance peak kulo lonke uluhlu lwamafrikhwensi luhamba kancinci ukuya kwicala eliphezulu.I-deformation ye-amplitude ye-coil yangaphandle ikakhulu ukwandiswa kwangaphandle, kwaye i-inductance iyonke ye-coil deformation iya kwanda, kodwa umgama phakathi kwee-coil zangaphakathi nangaphandle ziya kwanda, kwaye i-capacitance ye-wire cake emhlabeni iya kuncipha.Ke ngoko, incopho yokuqala ye-resonance kunye nentlambo kwi-curve ye-spectrum iya kuhamba ukuya kwicala eliphantsi le-frequency, kwaye ezi ncopho zilandelayo kunye neentlambo ziya kuhamba kancinci ukuya kwinqanaba eliphezulu.
