Voltage thiab loops ntawm transformers - teeb meem thiab kev daws teeb meem

1.

Raws li lub rooj saum toj no, nrhiav R thiab P.

tshuaj

Cov qauv ntawm Transformer:

V_s N_p = N_s V_p thiab V_p I_p =V_s I_s

V_s = qhov hluav taws xob theem ob, V_p = thawj voltageN_s = cov voj voog thib ob, N_p = cov voj voog thawj zaug_, I_p = thawj tam sim no, kuv_s = tam sim no theem ob

Lub zog hluav taws xob tseem ceeb (V _p )

V _pI p = _{V s} I _s

V _p (4) = (10)(80)

Vp ₌ 800 / 4

V _p = R = 200 Volt

Cov voj voog thib ob (N _s )

V _s N _p = N _s V _p

(10)(600) = N _s (200)

6000 = 200 N _s

Ns ₌ 6000 / 200

Ns ₌ P = 30 lub voj voog

2.

Raws li lub rooj saum toj no, nrhiav K thiab L.

Tshuaj:

Tam sim no theem ob ( _Is ) ntawm transformer 1:

V _pI p = _{V s} I _s

(200)(3) = (300)( _Is )

Kuv ₌ 600 / 300

Kuv ₌ K = 2 A

Qhov hluav taws xob theem ob (Vs ₎ ntawm transformer 2:

V _pI p = _{V s} I _s

(40)(0,75) = Vs ₍ 1)

V _s = L = 30 Volt

3.

Raws li lub rooj saum toj no, nrhiav P thiab Q.

Tshuaj:

Lub zog hluav taws xob tseem ceeb (V _p )

V _s N _p = N _s V _p

(220)(300) = (600) V _p

(220)(3) = (6) V _p

660 = 6 V _p

Vp ₌ 660 / 6

V _p = P = 110 Volt

Thawj qhov tam sim no (I _p )

V _pI p = _{V s} I _s

(110)(I _p ) = (220)(2)

(110)(I _p ) = 440

Kuv _p = 440 / 110

Kuv _p = Q = 4 A
