Chii Chinorasikirwa neTransformer?

Kurasikirwa kwesimba remagetsi rinosanganisira kurasikirwa nemhangura uye kurasikirwa nesimbi. Izvi zvinodaro nekuti chero michina yemagetsi inorasikirwa nenguva yakareba yekushanda, uye simba remagetsi harisi iro rinosiyana.

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 yekushandisa uye frequency: Kurasikirwa kwesimbi kwakabatana nevoltage yekushandisa uye frequency yetransformer nekuti zvinhu izvi zvinokanganisa simba remagnetic field uye hysteresis mu core.
• Zvinhu zvepakati: Hunhu hwe hysteresis hwezvinhu zvepakati hunokanganisa kukura kwekurasikirwa kwesimbi. Kana zvinhu zvepakati zvikasasarudzwa zvakanaka, kurasikirwa kwe hysteresis kuchawedzera.
• Maitiro ekugadzira: Maitiro ekugadzira etransformer anewo simba rakati pakurasikirwa kwesimbi. Semuenzaniso, nzira yepakati yekuisa simbi, kurapwa kwekudzivirira kupisa, nezvimwewo zvinokanganisa saizi yekurasikirwa kwesimbi.

Maitiro ekuderedza kurasikirwa kwesimbi yetransformer？

• Sarudza simbi yemhando yepamusoro: Kusarudza simbi yemhando yepamusoro ine kurasikirwa kudiki kwe hysteresis kunogona kuderedza kurasikirwa nesimbi kwetransformer.
• Gadzirisa maitiro ekugadzira: Deredza kurasikirwa nesimbi nekuvandudza nzira ye core lamination, kurapwa kwe insulation uye mamwe maitiro ekugadzira.
• Dhizaini ine musoro: Padanho rekugadzira transformer, kurasikirwa kwesimbi kunoderedzwa nekuvandudza dhizaini yechivakwa 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 yemazuva ano: Sezvambotaurwa pamusoro apa, kurasikirwa kwemhangura kunoenderana ne sikweya yemagetsi, saka saizi yemagetsi ndiyo chinhu chikuru chinokanganisa kurasikirwa kwemhangura.
• Kuramba kutenderedzwa: Kuramba kutenderedzwa kunokanganisa zvakananga kurasikirwa kwemhangura. Kuramba kuwedzere, kurasikirwa kwemhangura kwakawedzera.
• Huwandu hwemachira ecoil: Kana machira ecoil akawanda, nzira yekuti magetsi afambe mumhepo inotenderera inoreba, uye kuramba kunowedzera zvinoenderana nazvo, zvichikonzera kurasikirwa kwakanyanya kwemhangura.
• Kuchinja-chinja: Mhedzisiro yekuchinjisa-chinja pakurasikirwa kwemhangura yetransformer ine chekuita zvakananga nemaparamita ekugovera uye hunhu hwemutoro wetransformer. Kana hunhu hwemutoro uye maparamita ekugovera zviri inductive, kurasikirwa kwemhangura kunoderera sezvo frequency yekuchinja ichiwedzera; kana iri capacitive, kurasikirwa kwemhangura kunowedzera sezvo frequency yekuchinja ichiwedzera.
• Kukanganiswa 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: deredza kuramba kwemuchina wekufambisa, nokudaro zvichideredza kurasikirwa kwemhangura netransformer.
• Shandisa zvinhu zvemhando yepamusoro zvekufambisa: zvakaita sefoiri yemhangura kana foiri yearuminiyamu kuderedza kuramba kutenderera.
• Deredza nguva yekushanda kwetransformer ine mutoro wakareruka: Kuderedza huwandu hwenguva yekushanda kwetransformer ine mutoro wakareruka kunobatsira kuderedza kurasikirwa kwemhangura netransformer.
