The chete-danho transformer. Chinangwa, mamiriro uye chikuru unhu

Pane anguva chinosekesa Institute. On nyaya mudzidzisi "sei chete-danho transformer" vava kungotaura nezvekudzoka mudzidzi mukupindura: "! Oo-Oo-Oo". Ridzai ichi chaizvoizvo zvinoitika, akafanirwa chokuti kana iwe kufambisa induction munda ichibudira kuti rinobva striction maturo, zvichiita ndiro kuzunguza tsandanyama kuti rinobva vematunhu.

The chete-danho transformer kuti generating imwe rakatumbuka voltage nokuti mutoro achida ukoshi pasina yaida-danho matatu simba zvitengeswa.

Mumwe transformer ine mbiri dzinokosha zvinoriumba: Musimboti uye Coils navo haasi asingasviki maviri. Nheyo kushanda iri nyore. Somugumisiro achipfuura Magetsi kuburikidza nemunhu ari mukuru ichitenderera, dzisiri vakafurira electromotive simba (EMF). The Musimboti ine ferromagnetic mahwendefa i.e. kusimudzira zvinhu achisimbisa remagineti (zvemagetsi simbi chaiyo mamakisi).

Kwakakura pamusoro EMF pakutsvaga nzira:

E = 4.44 X F X F X ω

apo:

F - the amplitude of rinobva nekubudisa;

F - kakawanda magetsi;

ω - nhamba muchichinjana iri ichitenderera.

The bvumidzwa kutakura, iro "runokukura" chete-danho transformer, inopiwa muchikamu waya, izvo muchikuvadza Coils uye rinobva redunhu Q, kunyanya permeability ferromagnetic μ. Kukura chinoumba uye uwandu windings ndivo nyaya kukarukureta, izvo kazhinji nyaya kosi basa rwokugadzira kumayunivhesiti.

Chero zvazvingava, zvikuru simba chete-danho voltage transformer, zvikuru chaizvo kukura kwavo. On muviri wavo kazhinji ane Chikwata ine mazita dzinokosha parameters (zvinobvumidzwa kuitika kwezvavakaisa goho voltages). Zvisinei, izvi handizvo zvinoitika nguva dzose.

In tsika, vanogadzirisa vakawanda kazhinji nenguva yatinoona yokutsiva kupiswa-kunze chete-danho voltage transformer. Kuti ave nechokwadi suitability inofanira kuongororwa zvechadenga mudziyo, aida kutsiva.

Chinhu chokutanga kuita kuona mazano ichitenderera. At danho-pasi transformers ine mukuru nemishonga.

Zvadaro, akatendeuka ndokuita samambure, zvinokwanisika kuyera goho voltage pa simbe. Nhamba kwezvavakaisa goho emf ndiyo Kushandurwa coefficient K. Uyewo kuenzana zvikamu zviduku Rin N. / N O., I.e. nhamba muchichinjana vari windings.

Zvadaro, sezvo mutoro inogona kwakabatana simba shanduka nemishonga (resistor) uye kubvisa magetsi-voltage unhu nokududza yavose sezvavakatarirwa uno. Sezvo mutoro kunowedzera goho voltage zvishoma nezvishoma shoma.

Transformers havasi chete simba, asiwo kuyerwa. Muzviitiko kana zvakakodzera kutsanangura kuchikosha chitsama kuitika mudunhu kushandisa ammeter. Rinowanikwawo sequentially, uye vanofanira kuva pasi nemishonga akabatana hombe muchinjikwa-chikamu waya iri rinobva Kutsauka hurongwa. mudziyo kwakadaro kwaizova kudhura uye makuru, saka shandisa chete-danho ano transformers iyo bvisa proportionally kunoderedza kukosha, uye zvokudya navo kwakajairika Serial ammeters. Change amperage zviri nyore, zvazvinosarira chete kushandisa izvi zvinokonzera pamusoro muviri.
