Ukubheka okokuqala kuma-high frequency transformers, isingeniso sesimiso se-transformer

1, Isingeniso somgomo we-transformer

I-Transformer njengoba igama lisho, shintsha i-voltage yezinto zikagesi zikagesi.Kusetshenziswa umgomo we-Faraday electromagnetic induction ukuguqula idivayisi kagesi ye-AC, ikakhulukazi ikhoyili eyinhloko, insimbi core, ikhoyili yesibili nezinye izingxenye.Ingakwazi ukufeza ukuguqulwa kokufaka nokukhiphayo, ukuguqulwa kwe-voltage kanye ne-impedance efanayo, njll. Ingakwazi futhi ukufeza ukuhlukaniswa ngokomzimba kwesiteji sokuqala.Ngokusho kwe-voltage ehlukene yesiteji sokuqala, ingahlukaniswa ibe yi-transformer yesinyathelo-phansi, i-step-up transformer, i-isolation transformer, njll.

2, Ngokusho kwe-frequency yokusebenza ehlukene, ihlukaniswe i-low frequency transformer kanye ne-high frequency transformer.

Imvamisa kagesi wethu wokukhiqiza impilo yansuku zonke ngu-50 Hz, lokhu sikubiza ngamandla e-AC amandla aphansi we-AC.Uma i-transformer isebenza kule mvamisa, senza le transformer ibe yi-low-frequency transformer, ebizwa nangokuthi i-industrial frequency transformer.Lolu hlobo lwe-transformer lukhulu futhi alusebenzi kahle, umongo wenziwa ngokunqwabelanisa amashidi ensimbi e-silicon ahlanganiswe komunye nomunye, amakhoyili ayinhloko nawesibili alinyazwa ngocingo olunwetshiwe futhi amandla esiteji sokuqala alingana nenani lawo lokuphenduka.

Ngaphezu kwalokhu, amanye ama-transformer asebenza emashumini ezilungiselelo zama-kilohertz angamakhulu amaningana, futhi ama-transformers anjalo abe ama-high frequency transformers.Ama-transformer aphezulu ngokuvamile awasebenzisi i-iron core, kodwa i-core magnetic.Ama-high-frequency transformers ahlangene, anenani elincane lamakhoyili aphendukayo kanye nokusebenza kahle okuphezulu.

3, Umehluko we-transformer ephezulu nephansi kanye nokuxhumana.

Imvamisa yokusebenza kwe-high frequency transformer ngokuvamile iba kumashumi e-kilohertz kuya kumakhulu e-kilohertz, i-transformer isebenzisa umgogodla kazibuthe, ingxenye eyinhloko yomgogodla i-zinc ferrite ye-manganese, le nto etholakala ku-high frequency eddy current incane, ukulahlekelwa okuphansi, ukusebenza kahle okuphezulu. .I-low frequency transformer yokusebenza imvamisa yasekhaya ye-50 Hz, i-transformer core iyinsimbi ethambile kazibuthe, ishidi elincanyana lensimbi ye-silicon linganciphisa kakhulu ukulahleka kwamanje kwe-eddy, kodwa kunokulahlekelwa okuyisisekelo kwe-transformer ephezulu kusekukhulu.

I-transformer yamandla ephumayo efanayo, i-high-frequency transformer kunevolumu ye-low-frequency transformer incane kakhulu, isizukulwane sokushisa esiphansi.Ngakho-ke, i-adaptha yamandla kagesi yabathengi abaningi bamanje kanye nemikhiqizo yenethiwekhi, ishintsha ukunikezwa kwamandla, i-transformer yangaphakathi ye-high-frequency iyisici esibaluleke kakhulu sokushintshwa kwamandla kagesi.Isimiso esiyisisekelo ukuqala ukuguqula okokufaka kwe-AC kube yi-DC bese ngokusebenzisa i-transistor noma ishubhu le-field-effect libe yi-high-frequency ngokusebenzisa i-high-frequency transformer voltage, ngemva kokulungiswa kabusha okukhiphayo, kanye nezinye izingxenye zokulawula, i-DC voltage ephumayo ezinzile.

Ngamafuphi, ama-transformer aphezulu naphansi ayafana ekusetshenzisweni kwesimiso sokungeniswa kwe-electromagnetic, umehluko ku-low frequency transformer iyishidi lensimbi ye-silicon ehlanganiswe engxenyeni yensimbi, i-high frequency transformer i-zinc ferrite ye-manganese nezinye izinto. ibhulokhi lonke.
