Voltage na vitanzi vya transfoma - matatizo na suluhisho

1.

Kulingana na jedwali hapo juu, tafuta R na P.

Suluhisho

Mlinganyo wa transfoma:

V_s N_p = N_s V_p na V_p I_p =V_s I_s

V_s = volteji ya pili, V_p = msingi voltage, N_s = vitanzi vya pili, N_p = vitanzi vya msingi_, I_p = msingi sasa, Mimi_s = mkondo wa pili

Volti ya msingi (V _p )

V _p I _p = V _s I _s

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

V _p = 800 / 4

V _p = R = Volti 200

Mizunguko ya pili ( _Ns )

V _s N _p = N _s V _p

(10)(600) = N ₍ 200)

6000 = 200 _Ns

N ₌ 6000 / 200

N _s = P = vitanzi 30

2.

Kulingana na jedwali hapo juu, tafuta K na L.

Suluhisho:

Mkondo wa pili ( _Is ) wa transfoma 1:

V _p I _p = V _s I _s

(200)(3) = (300)(I _s )

I _s = 600/300

I _s = K = 2 A

Volti ya pili (Vs ₎ ya transfoma 2:

V _p I _p = V _s I _s

(40)(0,75) = Vs ₍ 1)

V _s = L = Volti 30

3.

Kulingana na jedwali hapo juu, tafuta P na Q.

Suluhisho:

Volti ya msingi (V _p )

V _s N _p = N _s V _p

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

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

660 = 6 V _p

V _p = 660 / 6

V _p = P = Volti 110

Mkondo wa msingi (I _p )

V _p I _p = V _s I _s

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

(110)(I _p ) = 440

I _p = 440 / 110

I _p = Q = 4 A
