Ruzivo rwetransformer

Transformer chishandiso chinoshandisa musimboti we electromagnetic induction kushandura AC voltage. Zvikamu zvayo zvikuru zvinosanganisira primary coil, secondary coil uye iron core.

Mubasa remagetsi, unogona kazhinji kuona mumvuri we transformer, iyo inonyanya kushandiswa mumagetsi se voltage yekushandura, isolation.

Muchidimbu, chiyero chemagetsi che coils dzekutanga nedzechipiri chakaenzana nechiyero chekutendeuka kwe coils dzekutanga nedzechipiri. Saka, kana uchida kuburitsa voltages dzakasiyana, unogona kushandura chiyero chekutendeuka kwe coils.

Zvichienderana nema frequency akasiyana ekushanda kwema transformer, anogona kukamurwa kuita ma transformer ane frequency yakaderera uye ma transformer ane frequency yakakwirira. Semuenzaniso, muhupenyu hwezuva nezuva, frequency ye power frequency alternating current i50Hz. Tinodaidza ma transformer anoshanda pa frequency iyi kuti ma transformer ane frequency yakaderera; frequency yekushanda kwe high-frequency transformer inogona kusvika makumi e kHz kusvika mazana e kHz.

Vhoriyamu yetransformer ine mafrequency akakwira idiki zvikuru pane yetransformer ine mafrequency akaderera ine simba rakafanana rekuburitsa.

Transformer iyi inhengo yakakura mu power circuit. Kana uchida kuderedza vhoriyamu uku uchivimbisa kuti simba rekubuda rinobuda, unofanirwa kushandisa high-frequency transformer. Saka, high-frequency transformers dzinoshandiswa pakuchinja magetsi.

Pfungwa yekushanda kwetransformer ine mafrequency akawanda uye transformer ine mafrequency akaderera yakafanana, zvose zviri zviviri zvichibva papfungwa ye electromagnetic induction. Zvisinei, maererano nezvinhu, "cores" dzavo dzinoshandisa zvinhu zvakasiyana.

Musoro wesimbi we transformer ine mafrequency akaderera unowanzo unganidzwa nemapepa akawanda esimbi esilicon, nepo musoro wesimbi we transformer ine mafrequency akakwira uchiumbwa nezvinhu zvine magineti zvine mafrequency akakwira (zvakadai se ferrite). (Naizvozvo, musoro wesimbi we transformer ine mafrequency akakwira unowanzo nzi musoro wemagnetic)

Mudunhu remagetsi rakasimba reDC, transformer ine frequency yakaderera inotumira chiratidzo chesine wave.

Mukushandura magetsi, transformer ine mafrequency akawanda inotumira chiratidzo che "high-frequency pulse square wave".

Pasimba rakarongwa, chiyero chiripo pakati pesimba rinobuda nesimba remuchina wekushandura chinonzi kushanda zvakanaka kwemuchina wekushandura. Kana simba rinobuda remuchina wekushandura rakaenzana nesimba rekupinda, kushanda zvakanaka kwemuchina uyu i100%. Kutaura zvazviri, muchina wekushandura wakadaro haupo, nekuti kurasikirwa kwemhangura nekurasikirwa kwesimbi kuripo, muchina wekushandura uchava nekurasikirwa kwakati.

Chii chinonzi kurasikirwa nemhangura?

Nekuti transformer coil ine resistance yakati, kana magetsi apinda nepakati pe coil, chikamu chesimba chinoshanduka kuva kupisa. Nekuti transformer coil yakaputirwa ne copper wire, kurasikirwa uku kunonziwo copper loss.

Chii chinonzi kurasikirwa nesimbi?

Kurasikirwa kwesimbi kwetransformer kunosanganisira zvinhu zviviri: kurasikirwa nehysteresis uye kurasikirwa ne eddy current; Kurasikirwa nehysteresis kunoreva kuti kana alternating current inopfuura nepakati pe coil, magnetic lines of force ichagadzirwa kuti ipfuure nepakati pe iron core, uye mamorekuru ari mukati me iron core achakweshana kuti agadzire kupisa, nokudaro achidya chikamu chesimba remagetsi; Nekuti magnetic line of force inopfuura nepakati pe iron core, iron core ichaburitsawo induced current. Nekuti current iri kutenderera, inonziwo eddy current, uye eddy current loss ichashandisawo simba remagetsi.
