Rashin ƙarfin wutar lantarki capacitor ramuwa-3 (Rashin ƙarfin wutar lantarki na gida)

Ramin Diyya na Capacitor na Gida don Da’irar Motoci

A cikin tsarin wutar lantarki na aiki, da’irar daidaitacciyar mafi yawan kayan lantarki (ciki har da motocin induction) za a iya ɗauka a matsayin da’irar jerin juriya $R$da inductance $L$. Ƙarfin wutar sa shine:

Lokacin da aka haɗa capacitor $C$a layi daya zuwa da’irar $R,L$, lissafin halin yanzu ya zama:

Hoto na 3 yana nuna zanen phasor na diyya.

Hoto na 3 Rashin Cikakken Diyya da Cikakken Diyya​

• A cikin zanen phasor na hagu (rashin cikakken diyya), vector na halin yanzu yana baya bayan phasor na wutar lantarki.

• A cikin zanen phasor na dama (cikakken diyya), vector na halin yanzu yana gaba da phasor na wutar lantarki.

Cikakken diyya gabaɗaya ba a so saboda yana iya haifar da ƙaruwa a cikin wutar lantarki ta biyu na transformer. Bugu da ƙari, ƙarfin wutar lantarki mai capacitive shima yana haifar da asarar makamashi kuma yana ƙara yawan zafin jiki da asarar capacitor, don haka yana shafar tsawon rayuwar sa.

Tebur na 1 yana ba da ƙarfin capacitor da aka ba da shawarar don inganta ƙarfin wutar lantarki na nauyin motoci:

Umurnin Amfani da Tebur:

1. Yanayin Diyya na Gabaɗaya:​ Ga nauyin mota mai ƙarfin wutar lantarki na yau da kullun na 0.7, idan ana buƙatar a biya shi zuwa 0.9, tebur yana ba da ma’aunin diyya na 0.586 kvar/kW. Ga ƙarfin aiki na 100 kW, jimlar ƙarfin capacitor da ake buƙata shine: 100 kW × 0.586 kvar/kW = 58.6 kvar.

2. Matsakaicin Iyaka:​ Ga motocin induction AC uku-lokaci, ƙarfin diyya Qc​ bai kamata ya wuce 90% na ƙarfin wutar lantarki mara nauyi na motar ba. Wannan don hana wutar lantarki mai yawa da za ta iya faruwa saboda cikakken diyya lokacin da aka kashe motar.

3. Ƙididdigar Lissafi Mai Sauƙi:​ Za a iya ƙididdige capacitor na diyya don nauyin motoci ta amfani da wannan ƙididdigar mai sauƙi:

   Qc​≤0.35Pn​

   inda

   Pn​ shine ƙarfin da aka ƙididdige na motar.

   Qc shine ƙarfin capacitor na diyya.
