Chii Chinorasikirwa neTransformer?

Chii chinonzi kukuvara kwesimbi?

Kusiyana nekurasikirwa nemhangura, kurasikirwa nesimbi kwetransformer hakuenderane nezvinhu zvakaita sekutenderera uye saizi yemagetsi. Kubva pamaonero ezita, kukuvara kwesimbi kwakabatana zvakanyanya nesimbi, kunogadzirwa nepakati pesimbi. Kurasikirwa nesimbi kwetransformer kunozivikanwawo se "kurasikirwa kwemutoro", izvo zvinokonzerwa nekuti kurasikirwa nesimbi kunogara kuripo mutransformer, kungave kuri mutoro wakazara kana kuti zero mutoro, uye ndekwekurasikirwa kwakagadzika kwetransformer. Zvisinei, panguva yekuremerwa, kurasikirwa kwesimba kuchaderera nekudzikira kwesimba remagetsi.

Kupatsanurwa kwekurasikirwa kwesimbi yetransformer

Kurasikirwa kwesimbi kwetransformer kwakakamurwa kuva kurasikirwa kwehysteresis uye kurasikirwa kwe eddy current.

Kurasikirwa neHysteresis

Pfungwa yekushanda kwetransformer yakavakirwa panheyo ye electromagnetic induction kuti pave nekukwira nekudonha kwemagetsi uye shanduko dzemagetsi. Kuyerera kwemagineti mutransformer kunoyerera pamusimboti wesimbi. Musimboti wesimbi une simba remagineti rekudzivirira simba remagetsi, sezvinoita kondakita ine simba rekudzivirira simba remagetsi. Saizvozvowo, kupisa kuchagadzirwawo, uye kurasikirwa uku kunonzi "hysteresis loss".

Kurasikirwa kweEddy current

Kana magetsi ashandiswa pakutenderera kwe transformer, simba remagetsi rinobuda mu coil rinoyerera mu iron core. Nekuti core pachayo ndiyo conductor, simba remagetsi rinokonzereswa mu plane yakatarisana ne magnetic field line. Simba iri rinogadzira closed loop mu cross section ye core, iyo inozogadzira magetsi emagetsi. Simba iri rinoita se rotating vortex, saka zita rekuti "vortex". Kurasikirwa kunokonzerwa ne eddy current kunonzi "eddy current loss". Imhaka yekuti core inogadzira eddy currents ndiyo inogadzirwa kuita sheet yakatetepa. Nekuti kana core yakatetepa, resistance yakakwira, simba remagetsi rinodzikira.

Zvinhu zvinokonzera kurasikirwa kwesimbi yetransformer

• Voltage inoshanda uye frequency:Kurasikirwa kwesimbi kunoenderana nemagetsi anoshanda uye frequency yetransformer nekuti zvinhu izvi zvinokanganisa simba remagineti uye hysteresis mukati memoyo.
• Zvinhu zvepakutanga:Hunhu hwe hysteresis hwechinhu chikuru huchakanganisa kukura kwekurasikirwa kwesimbi. Kana chinhu chikuru chisina kusarudzwa zvakanaka, kurasikirwa kwe hysteresis kuchawedzera.
• Maitiro ekugadzira:Maitiro ekugadzira transformer anewo simba guru pakurasikirwa kwesimbi. Semuenzaniso, nzira ye core lamination, kurapwa kwe insulation, nezvimwewo zvinokanganisa saizi yekurasikirwa kwesimbi.

Maitiro ekuderedza kurasikirwa kwesimbi yetransformer？

• Sarudza zvinhu zvesimbi zvemhando yepamusoro:Kusarudza simbi ine hysteresis shoma kunogona kuderedza kurasikirwa kwesimbi kwetransformer.
• Gadzirisa maitiro ekugadzira:Deredza kurasikirwa nesimbi nekuvandudza nzira ye core lamination, kurapwa kwe insulation uye mamwe maitiro ekugadzira.
• Dhizaini inonzwisisika:Muchikamu chekugadzira transformer, kurasikirwa kwesimbi kunoderedzwa nekuvandudza dhizaini yechimiro uye kusarudzwa kwema parameter.

Kurasikirwa nemhangura

Mhangura ine basa rakakosha mumatransformer. Waya dzemhangura dzinowanzo shandiswa mumawinding etransformer. "Kurasikirwa kwemhangura" mutransformer ndiko kurasikirwa kunokonzerwa newaya dzemhangura. "Kurasikirwa kwemhangura" kwetransformer kunonziwo kurasikirwa kwemutoro. Kunonzi kurasikirwa kwemutoro ndiko kurasikirwa kwakasiyana-siyana uye shanduko.

Inochinja nekuchinja kwemagetsi, kurasikirwa kwemhangura (kurasikirwa nemutoro) kurasikirwa kwakasiyana-siyana, uye ndiko kurasikirwa kukuru mukushanda kwetransformer.

Zvinhu zvinokonzera kurasikirwa kwemhangura yetransformer

• Saizi yazvino:Sezvambotaurwa pamusoro apa, kurasikirwa nemhangura kunoenderana ne sikweya yemagetsi, saka saizi yemagetsi ndiyo chinhu chikuru chinokanganisa kurasikirwa nemhangura.
• Kupikisa kupokana:Kuramba kwemuchina wekumonera kunokanganisa zvakananga kurasikirwa kwemhangura. Kana muchina wekumonera wakawanda, kurasikirwa kwemhangura kwacho kunowedzera.
• Huwandu hwezvikamu zve coil:Kana paine ma coil layer akawanda, nzira yekuti magetsi afambe mu winding inoreba, uye resistance inowedzera zvichienderana nazvo, zvichikonzera kurasikirwa kwakanyanya kwemhangura.
• Kuchinja kakawanda:Mhedzisiro yekuchinja frequency pakurasikirwa kwemhangura yetransformer ine chekuita zvakananga nematanho ekugovera uye hunhu hwemutoro wetransformer. Kana hunhu hwemutoro uye maparameter ekugovera zviri inductive, kurasikirwa kwemhangura kunoderera sezvo frequency yekuchinja ichiwedzera; kana iri capacitive, kurasikirwa kwemhangura kunowedzera sezvo frequency yekuchinja ichiwedzera.
• Kukanganisa kwekupisa:Kurasikirwa nemutoro kunokanganiswawo nekupisa kwetransformer. Panguva imwe chete, kubuda kwemvura inobuda nekuda kwesimba remutoro kuchakonzera kurasikirwa kwesimba remagetsi mumhepo inotenderera uye kurasikirwa kunobva muzvikamu zvesimbi zviri kunze kwemhepo inotenderera.

Nzira yekuderedza kurasikirwa kwemhangura yetransformer?

• Wedzera nzvimbo inomonereka yetransformer:kuderedza kuramba kwemuchina wekufambisa magetsi, nokudaro zvichideredza kurasikirwa kwemhangura netransformer.
• Shandisa zvinhu zvemhando yepamusoro zvemuchina wekufambisa:zvakaita sefoiri yemhangura kana foiri yearuminiyamu kuderedza kuramba kutenderedzwa.
• Deredza nguva yekushanda kwetransformer ine mutoro wakareruka:Kuderedza nguva yekushanda kwetransformer ine mutoro wakareruka kunobatsira kuderedza kurasikirwa kwemhangura netransformer.
