Transformer yog cov khoom siv tseem ceeb hauv kab sib kis. Yog li ntawd, kev nyab xeeb kev ua haujlwm ntawm transformer plays lub luag haujlwm tseem ceeb hauv daim phiaj kev nyab xeeb. Technical Engineers ntawm HUAYI Fais fab tshawb nrhiav qhov ua rau ntawm transformer winding deformation thiab qhov tshwm sim muaj kev phom sij los ntawm kev tshuaj xyuas qhov kev txhaum winding deformation ntawm cov transformers. Nws yog ib qho tseem ceeb rau tag nrho daim phiaj kev ruaj ntseg qhov kev ua haujlwm ib txwm muaj.
Peb Cov Kws Ua Haujlwm tau npaj siab tias thaum lub tshuab hloov pauv tau raug luv luv tam sim no lossis lwm yam cuam tshuam, qhov deformation yog raws li hauv qab no:
Lub deformation ntawm winding yog tshwm sim los ntawm sab nraud quab yuam xws li cuam tshuam, inclination thiab vibration thaum lub sij hawm thauj mus los, uas ua rau winding hloov chaw. Qhov no deformed winding muaj qhov loj me, tab sis tsuas yog qhov sib txawv txav mus rau qhov tseem ceeb hloov. Lub inductance ntawm winding, lub inter-cake capacitance yog tas li, thiab lub capacitance hloov. General capacitance raug txo. Nyob rau hauv qhov sib npaug Circuit Court, lub resonance ncov hloov mus rau lub siab zaus. Yog li piv nrog cov qub spectrums, txhua qhov taw tes resonance tseem muaj nyob rau hauv kev ntsuas spectrum, thiab tsis muaj kev hloov pauv tshwm sim, tab sis cov peaks hloov mus rau qhov siab zaus (mus rau sab xis).
Ib nrab deformation ntawm ncuav mog qab zib, ib co unfixed xov ncuav mog qab zib yog squeezed nyob rau hauv qhov kev txiav txim ntawm lub luv luv-circuit electromagnetic quab yuam, thiab lwm yam yog elongated, (txuas ncaj qha mus rau ob tug ncej ntawm lub hwj chim, thiab tsis muaj tam sim no nyob rau hauv cov khoom siv hluav taws xob) thiaj li hais tias lub capacitance. nruab nrab ntawm lub ncuav yog hloov. Lub deformation ua rau qee qhov inductances hauv qhov sib npaug ntawm qhov sib npaug kom loj dua thiab qee qhov ua me; lub capacitance ntawm ncuav qab zib uas nyob rau hauv parallel nrog lub inductance kuj hloov. Thaum ntsuas qhov spectrum, qee qhov resonance ncov txav mus rau qhov siab zaus, thiab qhov siab tshaj tus nqi txo; qee qhov taw tes resonance txav mus rau qhov tsawg zaus, thiab lub ncov taw tes nce. Lub deformation cheeb tsam thiab deformation degree ntawm cov ncuav qab zib yog txiav txim los ntawm kev hloov ntawm resonance ncov.
luv luv Circuit Court ntawm lem (txuas ncaj qha mus rau ob tug ncej ntawm lub hwj chim, thiab tsis muaj tam sim no nyob rau hauv cov khoom siv hluav taws xob), theoretically hais, tom qab lub winding tshwm sim luv luv Circuit Court ntawm lub lem, inductance tus nqi txo, lub spectrum nkhaus hloov ho, lub amplitude. nce, thiab qee qhov resonance point peaks ploj mus. Tab sis qhov no yog txoj kev xav, qhov tseeb nws yog qhov nyuaj kom tau txais nws. Thaum lub sijhawm ua haujlwm luv luv tshwm sim thaum lub sijhawm ua haujlwm, lub kauj yuav raug hlawv, cov roj hnyav yuav tawm mus, thiab lub siab nyem valve yuav pib. Lub sijhawm no, cov roj chromatography ntawm lub transformer (siab txawv) yuav tsis tsim nyog, thiab cov transformer yuav raug kuaj xyuas.
Lead txoj kev tshem tawm thiab deformation, vim tias cov hlau lead yog ntev heev, thaum nws tsis ruaj khov, kev hloov pauv deformation tshwm sim thaum lub sijhawm ua haujlwm. Thaum cov hlau lead raug tshem tawm, ob-chaw nres nkoj capacitance yuav hloov hauv qhov sib npaug. Thaum lub teeb liab ntawm qhov nkag ntawm lub teeb liab hloov chaw, tab sis cov hlau lead capacitance nyob rau tib lub sijhawm nrog rau lwm cov circuits, yog li nws cov chan 0 tsis cuam tshuam rau qhov nkhaus spectral. Txawm li cas los xij, qhov tso tawm cov hlau lead hloov pauv tshwm sim, qhov kev hloov pauv ntawm cov hlau lead capacitance yuav hloov pauv qhov zaus teb nkhaus, tshwj xeeb tshaj yog rau qhov ntau ntawm 300 kHz mus rau 1 MHz nkhaus. Yog li ntawd, hauv qhov kev sim tiag tiag, qhov chaw txhaj tshuaj yog qhov nruab nrab los tiv thaiv cov teebmeem saum toj no. Yog hais tias cov lead-rau-hauv av capacitance raug txo, lub amplitude nyob rau hauv lub zaus band nce, thiab vice versa. Yog tias cov txhuas-rau-hauv av capacitance loj dua, nws qhia tau hais tias cov hlau lead txav mus rau lub plhaub, thiab cov hlau lead-rau-hauv av capacitance yuav me dua, nws qhia tau hais tias cov hlau lead txav mus rau qhov winding.
Lub winding tau txais radial deformation, thaum lub winding raug rau lub radial quab yuam, puab winding tau cog lus rau sab hauv, ob txoj kab uas hla thiab inductance ua me me. Lub sijhawm no, qhov kev ncua deb ntawm sab hauv thiab sab nrauv windings yuav loj dua, thiab lub peev xwm ua me me, uas yuav ua rau lub resonance ncov point nyob rau hauv lub spectrum mus rau lub siab zaus, thiab amplitude nce.
Lub winding twists thiab deforms axially. Thaum lub coil qhov chaw ntawm transformers (siab variation) yog loj los yog ib co ntawm lawv yog displaced, nrog rau qhov kev txiav txim ntawm electromagnetic quab yuam, lub winding yog twisted rau hauv ib tug S duab axially. Lub sijhawm no, ib feem ntawm lub ncuav mog qab zib capacitance thiab av capacitance raug txo. Hauv kev ntsuas spectrum, qee qhov ntawm cov resonance peaks txav mus rau qhov siab zaus kev taw qhia, thiab qhov amplitude ntawm resonance ncov txo qis hauv qhov tsawg zaus, lub ncov ntawm qhov nruab nrab zaus nce me ntsis, thiab qhov ntau zaus tsis hloov.
