Matransformer ekusimudzira nekudzika pasi - matambudziko nemhinduro

1. Transformer ine coil yekutanga uye coil yechipiri ine nhamba yezvirukwa 500 ne5000. Voltage yekupinda i220 V. Voltage yekubuda chii?

Zvinozivikanwa:

Koiri huru (N _P ) = 500 zvishwe

Koiri yechipiri (Ns ₎ = zvishwe zviuru zvishanu

Voltage yekutanga (V _P ) = 220 Volts

Zvinodiwa: Voltage yechipiri (V _S )

Solution:

Vs / Ns ₌ V _p / _{N p}

Vs _/ 5000 = 220 / 500

Vs _/ 5000 = 0.44

Vs = (0.44) ₍ 5000)

Vs = ₂₂₀₀ Volt

2. Transformer ine coil yekutanga ine zvishwe 1200 uye coil yechipiri ine zvishwe 1000. Kana magetsi ari mu coil yekutanga ari 4 Ampere, saka magetsi ari mu coil yechipiri chii.

Zvinozivikanwa:

Koiri huru (N _P ) = 1200 zvishwe

Koiri yechipiri (N _S ) = 1000 zvishwe

Iyo magetsi ari mu primary coil (I _P ) = 4 Ampere

Zvinodiwa: Kuyerera kwemagetsi mu coil yechipiri (I _S )

Solution:

I _S / I _P = N _P / N _S

Iyo magetsi ari mu coil yechipiri:

I _S /4 = 1200/1000

I _S /4 = 1.2

I _S = 1.2 (4)

I _S = 4.8 Ampere

3. Voltage yechipiri i220 Volts uye voltage yekutanga i110 volts, saka kuenzanisa coil yechipiri necoil yekutanga ndiko…

Zvinozivikanwa:

Voltage yechipiri (V _S ) = 220 Volts

Voltage yekutanga (V _P ) = 110 Volts

Kudiwa: N _S / N _P

Solution:

V _S /V _P = N _S /N _P

220/110 = N _S / N _P

22/11 = N _S / N _P

2/1 = N _S / N _P

12/6 = N _S / N _P

Zvidimbu zvechipiri (N _{S kana} N ₂ ) = 1 N = N

Zvinodiwa: Voltage yekutanga (V _P )

Solution:

Vs / Ns ₌ V _p / _{N p}

24 / N = V _p / 11 N

24 / 1 = V _p / 11

24 = V _p / 11

V _p = (24)(11)

V _p = 264 Volt

Voltage yechipiri (V ₂ ) = 20 Volts

Zvinodiwa: Voltage yekutanga ( _V1 )

Solution:

V ₂ / N ₂ = V ₁ / N ₁

20 / 3 N = V ₁ / 21 N

20 / 1 = V ₁ / 7

20 = V ₁ / 7

V ₁ = (7)(20)

V ₁ = 140 Volt

6. Zvichienderana nemufananidzo uri pazasi, huwandu hwezvishwe zvechipiri zvetransformer hungani.

Zvinozivikanwa:

Zvidimbu zvekutanga (N _P ) = zvidimbu mazana maviri

Voltage yechipiri (V _S ) = 1100 Volts

Zvinodiwa: Zvidimbu zvechipiri (N _S )

Solution:

Vs / Ns ₌ V _p / _{N p}

1100 Volts / Ns ₌ 220 Volts / 200 loops

1100 / N ₌ 220 / 200

Zvinozivikanwa:

Voltage yekutanga (V _P ) = 220 Volts

Zvidimbu zvekutanga (N _P ) = zvidimbu mazana maviri

Voltage yechipiri (V _S ) = 1100 Volts

Zvinodiwa: Zvidimbu zvechipiri (N _S )

Solution:

Vs / Ns ₌ V _p / _{N p}

1100 / N ₌ 220 / 200

1100 / N ₌ 22 / 20

1100 / N ₌ 1.1

N _S = 1100 / 1.1

N _S = 1000
