Pane zvinoenderana tekinoroji zvinodiwa kune akasiyana marudzi eshanduko, ayo anogona kuratidzwa neanoenderana tekinoroji paramita.Semuenzaniso, iwo makuru tekinoroji maparamendi emagetsi ekushandura anosanganisira: yakayerwa simba, yakayerwa voltage uye voltage reshiyo, yakayerwa frequency, yekushanda tembiricha giredhi, tembiricha kukwira, voltage regulation rate, insulation performance uye hunyoro kuramba.Kune general low-frequency transformers, iwo makuru tekinoroji paramita ndeaya: shanduko reshiyo, frequency maitiro, nonlinear kukanganisa, magineti kudzivirira uye electrostatic kudzivirira, kunyatsoita, nezvimwe.
Iwo makuru ma paramita e transformer anosanganisira voltage reshiyo, frequency maitiro, yakayerwa simba uye kushanda nesimba.
(1)Voltage ration
Hukama huri pakati pevoltage ratio n yetransformer uye kutendeuka uye voltage yepuraimari neyechipiri mamhepo ndeaya anotevera: n=V1/V2=N1/N2 uko N1 ndiyo yekutanga (yekutanga) mhepo inotenderera yetransformer, N2 ndiyo yechipiri (yechipiri) mhepo inotenderera, V1 ndiyo voltage kumagumo ese ekutanga mhepo, uye V2 ndiyo voltage kumagumo ese echipiri mhepo.Iyo voltage reshiyo n yedanho-up transformer iri pasi pe1, iyo voltage ratio n yedanho-pasi transformer yakakura kupfuura 1, uye chiyero chevoltage chega chega chega chakaenzana ne1.
(2)Yakatemerwa simba P Iyi parameter inowanzoshandiswa kune magetsi emagetsi.Inoreva simba rinobuda apo simba rekushandura rinogona kushanda kwenguva yakareba risingapfuure tembiricha yakatarwa pasi peiyo yakataurwa frequency yekushanda uye voltage.Iyo yakatemerwa simba retransformer inoenderana nenzvimbo yechikamu chesimbi core, dhayamita ye enamelled waya, etc. The transformer ine hombe simbi core chikamu nzvimbo, gobvu enamelled waya dhayamita uye guru goho simba.
(3)Frequency characteristic Frequency character inoreva kuti transformer ine imwe frequency yekushanda, uye ma transformer ane akasiyana ma frequency rengesheni haagone kuchinjika.Kana iyo transformer ikashanda kupfuura huwandu hwayo, tembiricha inokwira kana iyo transformer haishande zvakajairika.
(4)Kubudirira kunoreva chiyero chesimba rinobuda uye simba rekuisa retransformer payakayerwa mutoro.Kukosha uku kunoenderana nesimba rekubuda kweshanduro, ndiko kuti, iyo yakakura simba rekubuda remushanduri, iyo yakanyanya kunaka;Iyo diki iyo inoburitsa simba retransformer, yakaderera iyo inoshanda.Iko kukosha kwekushanda kweshanduko kunowanzo pakati pe60% ne100%.
Pasimba rakayerwa, chiyero chesimba rinobuda uye simba rekuisa retransformer inonzi mashandiro ekushandura, kureva
η= x100%
Kupiη Iko kushanda kweiyo transformer;P1 ndiro simba rekuisa uye P2 ndiro simba rekubuda.
Kana iyo inobuda simba P2 ye transformer yakaenzana neiyo yekuisa simba P1, iko kushandaη Yakaenzana ne100%, iyo transformer haizoburitsa chero kurasikirwa.Asi chaizvoizvo, hapana transformer yakadaro.Apo transformer inotumira simba remagetsi, inogara ichibudisa kurasikirwa, iyo inonyanya kusanganisira kurasikirwa kwemhangura uye kurasikirwa kwesimbi.
Kurasika kwemhangura kunoreva kurasikirwa kunokonzerwa nekupokana kwecoil ye transformer.Kana yazvino ichipisa kuburikidza nekoiri kuramba, chikamu chesimba remagetsi chinoshandurwa kuita kupisa simba uye kurasikirwa.Sezvo coil ichiwanzokuvadzwa netambo yemhangura yakavharidzirwa, inonzi kurasikirwa kwemhangura.
Kurasikirwa kwesimbi ye transformer kunosanganisira zvinhu zviviri.Imwe ndeye hysteresis kurasikirwa.Kana iyo AC ikozvino inopfuura nemushanduri, kutungamira uye kukura kweiyo magineti mutsara wesimba unopfuura nesilicon simbi pepa retransformer inochinja zvinoenderana, zvichiita kuti mamorekuru ari mukati mesilicon simbi simbi kukweshana uye kuburitsa kupisa simba. nokudaro kurasikirwa nechikamu chesimba remagetsi, iyo inonzi hysteresis kurasikirwa.Imwe yacho ndeye eddy ikozvino kurasikirwa, apo transformer iri kushanda.Kune mutsara wemagineti wesimba unopfuura nepakati pesimbi musimboti, uye iyo induced ikozvino inogadzirwa pane iyo ndege perpendicular kune iyo magineti mutsara wesimba.Sezvo iyi yazvino ichiumba chivharo chakavharwa uye ichitenderera muchimiro chechamupupuri, inonzi eddy current.Kuvepo kweeddy current kunoita kuti iron core inopisa uye inopedza simba, inonzi eddy current loss.
Kubudirira kwemushanduri kunonyatsoenderana nehuwandu hwemagetsi emushanduri.Kazhinji, iyo yakakura simba iri, idiki kurasikirwa uye kubuda kwesimba kuri, uye nepamusoro kugona kuri.Pane zvinopesana, iyo idiki simba, iyo yakaderera iyo inoshanda.
