Question

Під час вмикання обмотки А трансформатора в коло змінного струму напруга в обмотці В становить 600В. У разі вмикання в цю мережу обмотки В, напруга на обмотці А становить 150 В. Визначити відношення кількості витків обмоток трансформатора

Answer 1

Відповідь:

U1=600

U2=150

U1/U2=N1/N2

N1/N2=600/150=4/1

Відношення кількості витків=4:1

Calculation of the Turns Ratio of the Transformer

To determine the turns ratio of the transformer, we can use the relationship between the voltages and the number of turns in the windings. The turns ratio is defined as the ratio of the number of turns in the primary winding (winding A) to the number of turns in the secondary winding (winding B).

Let's denote the number of turns in winding A as N_A and the number of turns in winding B as N_B.

According to the given information, when the voltage in winding A is 600V, the voltage in winding B is 150V. We can use this information to calculate the turns ratio.

The turns ratio is given by the formula:

Turns Ratio = N_A / N_B = V_A / V_B

where V_A is the voltage in winding A and V_B is the voltage in winding B.

Using the given values, we can substitute them into the formula:

N_A / N_B = 600V / 150V

Simplifying the equation:

N_A / N_B = 4

Therefore, the turns ratio of the transformer is 4:1. This means that for every 4 turns in the primary winding (winding A), there is 1 turn in the secondary winding (winding B).

Please note that the calculation assumes an ideal transformer with no losses. In practice, there may be some losses due to factors such as resistance and magnetic leakage.
