Question

Трансформатор повышает напряжение с 220в до 660в и содержит в первичной обмотке 840 витков. Каков коэфициент трансформации? Сколько всего витков содержится во вторичной обмотке? Помогите не знаю как решать!!!!!

Answer 1

коэффициент трансформации = 660/220 = 3

витков во вторичной обмотке = 840*3=2520

 

Ответ:

коэффициент трансформации = 3

витков во вторичной обмотке = 2520 витков

 

Answer 2

Transformer Voltage Ratio and Number of Turns

To determine the voltage ratio and the number of turns in the secondary winding of a transformer, we can use the formula:

Voltage ratio (Vr) = Secondary voltage (Vs) / Primary voltage (Vp)

In this case, the primary voltage (Vp) is 220V, and the secondary voltage (Vs) is 660V. Therefore, the voltage ratio can be calculated as follows:

Vr = 660V / 220V = 3

The voltage ratio of the transformer is 3.

To find the number of turns in the secondary winding, we can use the formula:

Number of turns in secondary winding (Ns) = Voltage ratio (Vr) * Number of turns in primary winding (Np)

Given that the number of turns in the primary winding (Np) is 840, we can calculate the number of turns in the secondary winding as follows:

Ns = 3 * 840 = 2520

Therefore, the transformer contains a total of 2520 turns in the secondary winding.
