Sei kukosha kweAL kwetransformer kusina kugadzika kune magnetic core imwe chete?

Yepakutanga: Chiedza cheMidziyo

Mukuverenga kwedzidziso, tinofunga kuti kukosha kweAL kwe magnetic core imwecheteyo kwakasimba uye hatifungi nezvekukanganiswa kwezvimwe zvinhu pamutengo we AL. Zvisinei, mukushanda kwayo, kukosha kwe AL kunokanganiswa nezvinhu zvakasiyana-siyana. Chinyorwa chino chichatsanangura nemienzaniso kubva kunhengo dzeboka.
Ndine magnetic core ine 8Ts coils, uye inductance yakaedzwa inosvika 5.3uH; Asi pandakaedza ne80Ts coil, inductance value yaive 610uH. Chii chakaita kuti izvi zviitike?
Mukufunga, ma80T anofanira kunge ari pa530uH. Kuedza kwe coil imwe chete kunoshandisa ma magnetic cores akafanana nerudzi urwu rwe flat coil.

Tora mufananidzo wechigadzirwa chose, kusanganisira chimiro che magnetic core ne coil, uye kana paine mhepo isina chinhu here? Fekitori ye magnetic core inotsanangurawo AL value se 10 turns, uye kukanganisa kwakajairika hakusi kukuru kudaro.
Kana huwandu hwematenderedzwa huri hudiki, huwandu hwematenderedzwa anobuda kubva pakubuda kuenda pakubuda huchava hukuru, saka kukanganisa kwematenderedzwa kuchava kukuru kana huwandu hwematenderedzwa huri hudiki; Pamusoro pezvo, matenderedzwa akatsetseka achawedzera mhedzisiro iyi, uye kana iri coil yakajairwa, mhedzisiro yacho inogona kuva diki.
Imwe nyaya ndeyekuyedza kutsauka. Kana huwandu hwekutenderera hudiki, kunzwa kushoma, uye mhedzisiro yehysteresis ine simba guru pakutsauka kwekutenderera kwekuyedza; Ehe, pane mukana wekuti magnetic core inoguta kana huwandu hwekutenderera hudiki, saka kukosha kwekunzwa kwekuyedza hakusi kwechokwadi.

Pane mukaha wemhepo, uye mufananidzo wechigadzirwa ndewekuti:

Ma AL values ​​ese ari ma test values ​​asina air gap, saka zvakajairika kuti uve ne air gap.

Tinofanira kufunga nezve simba remugero wemhepo pano. Rudzii rwemagnetic core uye zvinhu zvayo? Mugero wemhepo wakadzama zvakadii?

Panyaya iyi, ndakatanga kufunga kuti zvaive nekuda kwemukana wemhepo. Zvichibva pamafomula nepfungwa huru dziri muchinyorwa chinoti “Kuverenga uye Tsananguro yeMuenzaniso weMukakana weMhepo muTransformers”, kuverenga kwakakodzera kwakaitwa.
Kuenzanisa kunoratidza kuti kukanganiswa kwemhepo haina kukosha zvakanyanya. (Hazvidzokororwi pano. Mapoka anofarira anogona kuverenga nekuenzanisa mutsauko mukunzwa nekubatanidza mafomula uye ma parameter ekutanga ema magnetic cores.)
Kunyanya kune imwe magnetic core, gap yemhepo haina kuchinjika. 80TS ndeyemamiriro ezvinhu ane nhamba yakakura yekutenderera. Pamwe chete nechimiro, ndakafungawo nezvefomula L=(0.01 * D * N * N)/(L/D+0.44) yemakoiri asina chinhu. Sezvo nhamba yekutenderera ichiwedzera, inductance yekutenderera kwega kwega inowedzera.
Kana paine madenderedzwa akawanda, chinhu ichi chichava chinonyanya kukosha, izvo zvinoita kuti tsananguro yacho ive nemusoro.

Kunewo data rinoratidza kuti sezvo huwandu hwematenderedzwa huchiwedzera, inductance coefficient inowedzera nekuti kutenderera kwega kwega mu coil kwakaenzana nekugadzira magnetic flux, iyo inowedzera nenhamba yematenderedzwa.
Zvichibva pane zvidzidzo zvenyaya iyi, ndakaongorora zvimwe zviitiko zvakawanda, uye munyaya iyi, inductance yakakura kwazvo. Zvinosuwisa kuti parizvino hapana nzira chaiyo yekupfupisa chiitiko ichi.
Zvinoita sekuti mukugadzirwa kwezvinhu zvakawanda, matransformer anofanira kushandisa coil imwecheteyo kupwanya mhepo, uye panewo zvinhu zvinofanira kufungwa nezvazvo panyaya iyi.
