Tansufa a Karamin Kula

Tsayi na Wuya na Transformer

Idan transformer yake yi aiki a cikin tsayi, wuyar gaba tana da jama, kuma tana bukatar yanayi a gaban gaba da ya haifar da adadin yanayi na gaba zuwa sifili. Wuyar mafi yana da yanayi mai tsayi I0, wadannan sun fi dace 2 zuwa 10% daga adadin yanayi na rike. Yanayin yana bayar wasu muhimmiyar hankali (hysteresis da eddy current losses) a fili da kayan yanayin mai yawa a wuyar mafi.

Karamin fili na I0 tana nuna kan hankalin transformer, amma mutaneen fatorin abokin yanayi tana cika da damu - tare da 0.1 zuwa 0.15.

Sunan Abubuwa na Yanayin Mai Tsayi

Yanayin mai tsayi I₀ sun hada da biyu abubuwa:

• Babban Abubuwa (Magnetizing Component) Im

• A cikin quadrature tare da kashi na shirya V₁

• Yana samun fili na fili bili karfi

• Farkon Abubuwa (Power Component) I_w

• A cikin phase tare da V₁

• Yana bayar wasu hankali na fili da kayan yanayin mai yawa a wuyar mafi

• Babban abubuwan I_m tana cikin phase tare da fili na magana, domin ya samu babban fili.

• EMFs na E₁ da E₂ a wuyar mafi/gaba suna haifar da fili na ϕ da 90°.

• Hankalin kayan yanayin mafi suna da damu, kuma yanayin gaba I2 = 0, ta haka tana bukatar hankalin gaba.

• Yanayin mai tsayi I0 tana haifar da V1 da fili na ϕ₀ (fili na fatorin abokin yanayi), kamar yadda aka nuna a diagrammai phasor.

• Kashi na shirya V₁ tana rubuta da damu da E₁, saboda farkon su a cikin tsayi tana da damu.

• Farkon abubuwan I_w tana cikin phase tare da V₁.

• Yanayin mai tsayi I₀ tana cikin summan I_m da I_w.
