Diagramma na Phasor na Matar Tauri na Kafuwa
Diagram Phasor Ta Amsa
Diagram phasor shine tushen bayanannin hanyar mafi girman kayayyakin kimiyya a cikin jirgin AC, kuma a nan yana amfani da shi wajen gindabban sarki.
Muhimmin Raisu
Ef wanda ya nufin tsari na excitation
Vt wanda ya nufin tsari na terminal
Ia wanda ya nufin adadin karamin armature
θ wanda ya nufin zabi na phase bayan Vt da Ia
ᴪ wanda ya nufin zabi na angle bayan Ef da Ia
δ wanda ya nufin zabi na angle bayan Ef da Vt
ra wanda ya nufin resistance na armature per phase
Muhimmin Phasor
A diagram, phasor na excitation voltage (Ef) yana daɗe mulki na terminal voltage (Vt), wanda yana da muhimmanci a fahimtar aiki na gindabba.
Tsari Na Aiki
Diagram phasor sun haɗa da tsari na aiki—lagging, unity, da leading power factors—wanda suke yawa hanyoyin mafi girman tsari da adadin karamin.
Diagram Phasor Na Motor Synchronous
Fahimtar diagram phasor na motor synchronous yana taimakawa wajen neman da take care of electrical behavior a cikin fadada power factor daban-daban.
Misali
Aiki na lagging power factor
Zan iya faɗa expression na Ef tare da kowane component na Vt a haguwar Ia. Component na Vt a haguwar Ia shine VtcosΘ, saboda haka total voltage drop shine along the I
Daga baya zan iya faɗa total voltage drop perpendicular to Ia. Total voltage drop perpendicular to Ia shine . Da takarda triangle BOD a first phasor diagram zan iya faɗa expression na E
Aiki na unity power factor
A nan zan iya faɗa expression na E
f tare da kowane component na Vt a haguwar Ia. Amma a nan value na theta shine zero kuma saboda haka zan iya cewa ᴪ = δ.
Da takarda triangle BOD a second phasor diagram zan iya faɗa expression na Ef as
Aiki na leading power factor.
Component a haguwar Ia shine VtcosΘ. Saboda haguwar Ia shine sama da Vt don haka total voltage drop shine .
Daga baya zan iya faɗa expression na voltage drop along the direction perpendicular to Ia. Total voltage drop yana samu . Da takarda triangle BOD a first phasor diagram zan iya faɗa expression na E
