Chekutanga pane zvese, nezvekuti simba rinogona kuchengetwa here, ngatitarisei mutsauko uripo pakati peakanaka mashanduri uye chaiwo anoshanda mashanduri:
1. Tsanangudzo uye maitiro eakanaka transformers
Yakajairika yekudhirowa nzira dzeakanaka transformers
Iyo yakanaka transformer chinhu chakasarudzika chedunhu. Iyo inofungidzira: hapana magineti inodonha, hapana kurasikirwa kwemhangura uye kurasikirwa kwesimbi, uye kusingaperi-inductance uye mutual inductance coefficients uye haichinji nenguva. Pasi pefungidziro idzi, transformer yakanaka inongoona shanduko yevoltage uye yazvino, isingabatanidzi kuchengetedza kwesimba kana kushandisa simba, asi inongoendesa iyo yekupinza simba remagetsi kusvika kumagumo ekubuda.
Nekuti hapana magineti kuvuza, iyo magineti yeakanaka transformer inovharirwa zvachose kupakati, uye hapana magineti simba remagetsi rinogadzirwa munzvimbo yakatenderedza. Panguva imwecheteyo, kusavapo kwekurasikirwa kwemhangura uye kurasikirwa kwesimbi kunoreva kuti transformer haizoshanduri simba remagetsi mukupisa kana mamwe maitiro ekurasikirwa kwesimba panguva yekushanda, uye haizochengetedzi simba.
Zvinoenderana nezviri mu "Circuit Principles": Kana transformer ine iron core ichishanda mune isina unsaturated core, iyo magineti permeability yakakura, saka inductance yakakura, uye kurasikirwa kwepakati hakuna basa, inogona kutaridzika seyakanaka. transformer.
Ngatitarisei mhedziso yake zvakare. "Mushanduro yakanaka, simba rinotorwa nemhepo yekutanga mhepo i1i1, uye simba rinotorwa nechipiri mhepo i2i2 = -u1i1, kureva kuti, simba rekuisa kudivi rekutanga re transformer rinobuda kumutoro kuburikidza ne divi rechipiri. Simba rose rinotorwa neshanduro ndeye zero, saka iyo yakanaka transformer inhengo isingachengete simba kana kushandisa simba.
” Zvechokwadi, dzimwe shamwari dzakataurawo kuti muflyback circuit, transformer inogona kuchengeta simba. Muchokwadi, ndakatarisa ruzivo uye ndakaona kuti yayo yakabuda transformer ine basa rekuchengetedza simba mukuwedzera pakuwana kuparadzaniswa kwemagetsi uye kuenderana kwemagetsi.Iyo yekare ndiyo pfuma ye transformer, uye iyo yekupedzisira ndiyo pfuma yeinductor.Naizvozvo, vamwe vanhu vanoidana iyo inductor transformer, izvo zvinoreva kuti iyo yekuchengetedza simba ndiyo inductor pfuma.
2. Hunhu hwevashanduri mukushanda chaiko
Pane humwe huwandu hwekuchengetedza simba mukushanda chaiko. Mumashanduri chaiwo, nekuda kwezvinhu zvakadai sekudonha kwemagineti, kurasikirwa kwemhangura uye kurasikirwa kwesimbi, shanduri ichava nehuwandu hwekuchengetedza simba.
Iyo iron core ye transformer inoburitsa hysteresis kurasikirwa uye eddy ikozvino kurasikirwa pasi pechiito chekuchinjanisa magineti. Kurasikirwa uku kuchapedza chikamu chesimba muchimiro chesimba rekupisa, asi zvinozoita kuti imwe huwandu hwesimba remagineti richengetwe musimbi core. Naizvozvo, kana iyo transformer ikaiswa mukushanda kana kubviswa, nekuda kwekuburitswa kana kuchengetwa kwesimba remagineti musimbi musimboti, kuwedzeredza kwenguva pfupi kana kuvhiya chiitiko kunogona kuitika, zvichikonzera kukanganisa kune imwe midziyo muhurongwa.
3. Inductor simba rekuchengetedza maitiro
Apo ikozvino munharaunda inotanga kuwedzera, iyoinductorzvinokanganisa shanduko yezvino. Zvinoenderana nemutemo weelectromagnetic induction, iyo inozviitisa yemagetsi simba inogadzirwa pamativi ese einductor, uye kutungamira kwayo kunopesana negwara rekuchinja kwazvino. Panguva ino, simba remagetsi rinoda kukunda iro rinozviitisa electromotive simba rekuita basa uye kushandura simba remagetsi kuita magineti simba mune inductor yekuchengetera.
Apo ikozvino inosvika kune imwe nyika yakagadzikana, iyo magnetic field mu inductor haichashanduki, uye iyo yega-induced electromotive simba i zero. Panguva ino, kunyange zvazvo inductor isisiri kutora simba kubva kune magetsi, inoramba ichichengetedza magnetic field simba rakachengetwa kare.
Apo ikozvino munharaunda inotanga kuderera, iyo magnetic field muinductor ichaitawo simba. Zvinoenderana nemutemo we electromagnetic induction, inductor inoburitsa yega-induced electromotive simba munzira imwechete sekuderera kwazvino, ichiedza kuchengetedza ukuru hweizvino. Mukuita uku, simba remagineti rakachengetwa muinductor rinotanga kuburitswa uye kushandurwa kuita simba remagetsi kuti ridzore kudunhu.
Kuburikidza nemaitiro ayo ekuchengetedza simba, isu tinogona kungonzwisisa kuti kana tichienzaniswa neshanduko, inongove ine simba rekuisa uye haina simba rinobuda, saka simba rinochengetwa.
Zviri pamusoro ndiwo maonero angu pachangu. Ndinovimba ichabatsira vese vagadziri veakakwana mabhokisi eshanduko kuti vanzwisise vashanduri uye inductors! Ndinodawo kugoverana newe ruzivo rwesainzi:madiki transformers, inductors, uye capacitors disassembled kubva midziyo yemumba inofanira kubudiswa isati yabatwa kana kugadziriswa nenyanzvi mushure mekudzimwa kwemagetsi!
