Teoriya na Transformer a Tsakiyar Kula da Sabon Kula

A nan da koyarwa daga wani abu mai tsarki don in iya fahimta tsarin tsari na turbin. Duk da haka za a yi amfani da muhimmin abubuwa masu yawa a kan turbin mai 'yan karamin sanyi, za a tattauna zabe na turbin a cikin waɗanda. Idan an ambaci, a cikin turbin mai tsarki, ba a ne abubuwa ga alama a cikin turbin, ya'ni alama mai baya. Amma a cikin turbin mai yawan amfani, akwai abubuwan hysteresis da abubuwan eddy current a cikin alama na turbin.

Tsari na Turbin Da Ba A Nauyi

Ba Da Abubuwan Hada Karamin Sanyi Da Sabon Alama

Za a duba wani turbin da aka amfani da shi da abubuwan alama kawai, ya'ni, akwai abubuwan alama kawai amma ba a ne abubuwan hada karamin sanyi ko sabon alama. Idan an kara magana mai yankin a kan primary, zai bayar da karamin sanyi don in ita alama na turbin.

Amma wannan karamin sanyi ba shi daidai, ya'ni, yana da shi kadan da karamin sanyi. Duka karamin sanyi da aka bayar ta source na da biyu abubuwa, wata shi ne karamin sanyi da aka amfani don ita alama, wanda na biyu na shi ne karamin sanyi da aka amfani don in gajarta abubuwan alama a cikin turbin.

Saboda haka, karamin sanyi a cikin turbin da ba a nauyi da aka bayar ta source, ba shi daidai 90° lagging supply voltage, amma lagging angle θ yana da shi kadan da 90o. Idan duka karamin sanyi da aka bayar ta source yana da shi Io, zai da shi wata abubuwa da take daidai da supply voltage V1, wanda wannan abubuwar karamin sanyi Iw ne abubuwan alama.

Wannan abubuwa an kawo daidai da supply voltage saboda ana amfani da shi a cikin abubuwan alama da ke kula a cikin turbin. Wanda na biyu na abubuwan karamin sanyi yana da shi denoted as Iμ.

Wannan abubuwa yana gina alternating magnetic flux a cikin alama, saboda haka, ba ake amfani shi, ma'ana yana da reactive part of the transformer source current. Saboda haka, Iμ yana daidai da V1 da alternating flux Φ. Saboda haka, duka karamin sanyi na primary a cikin turbin da ba a nauyi yana iya a nufin:

Idan kana gano, yana da kyau in bayyana tsari na turbin a cikin da ba a nauyi.

Tsari na Turbin Da A Nauyi

Ba Da Abubuwan Hada Karamin Sanyi Da Sabon Alama

Duk da haka za a duba hakan da aka amfani a cikin turbin da a nauyi, ya'ni nauyin da aka kara a kan secondary terminals. Duba, wani turbin da aka amfani da abubuwan alama amma ba a ne abubuwan hada karamin sanyi ko sabon alama. Idan an kara nauyi a kan secondary winding, karamin sanyi na nauyi zai faruwar su a cikin nauyi da secondary winding.

Wannan karamin sanyi na nauyi yana da shi mafi girman nauyi da kuma secondary voltage of the turbin. Wannan karamin sanyi an kira secondary current ko karamin sanyi na nauyi, a nan an kira I2. Saboda I2 yana faruwar su a cikin secondary, zai gina self MMF a cikin secondary winding. A nan yana da N2I2, inda, N2 yana da takaitaccen turns of the secondary winding of the transformer.

Wannan MMF ko magnetomotive force a cikin secondary winding yana gina flux φ2. Wannan φ2 yana juye main magnetizing flux da kuma yana gajarta main flux da kuma yana gaji primary self-induced emf E1. Idan E1 yana da shi kadan da primary source voltage V1, zai bayar da karamin sanyi daban-daban daga source zuwa primary winding.

Wannan karamin sanyi daban-daban I2′ yana gina flux φ′ a cikin core wanda zai gajarta counter flux φ2. Saboda haka, main magnetizing flux of core, Φ yana da shi kadan ba a nauyi. Saboda haka, duka karamin sanyi, wannan turbin yana bayar ta source zai da shi biyu abubuwa.

Wata shi ne da aka amfani don ita alama da kuma gajarta abubuwan alama, ya'ni, Io. Wannan shi ne no-load component of the primary current. Wanda na biyu ne da aka amfani don gajarta counter flux of the secondary winding. Wannan an kira load component of the primary current. Saboda haka, duka no-load primary current I1 of an electrical power transformer da ba a ne winding resistance and leakage reactance yana iya a nufin:

Inda θ2 yana da shi angle between the Secondary Voltage and Secondary Current of the transformer.
Duk da haka za a yi karfin waɗanda a kan tsarin turbin mai yawan amfani.

Tsari na Turbin Da A Nauyi, Da Hada Karamin Sanyi, Amma Ba Da Sabon Alama

Duk da haka, za a duba winding resistance of the transformer amma ba a ne leakage reactance. Tashen da aka amfani, turbin da aka amfani da ideal windings, ya'ni winding da ba a ne resistance and leakage reactance, amma duk da haka za a duba wani turbin da aka amfani da internal resistance in the winding amma ba a ne leakage reactance. Saboda winding yana da resistance, zai da drop a cikin voltage a cikin winding.

An samun da, total primary current from the source on load is I1
