1. Способ компенсации Э.Д.С. самоиндукции в искробезопасных трансформаторах посредством встречно-параллельного подключения контробмотки к основной обмотке, которые размещают на общем сердечнике, отличающийся тем, что с целью полной компенсации Э.Д.С. самоиндукции в основной обмотке число витков W2 и диаметр провода r2 контробмотки задают в соответствии с соотношениями:
W2= W1•β;
Figure 00000001

Figure 00000002

где α - отношение магнитных энергий основной обмотки и контробмотки, и этот параметр задают из экономических соображений в диапазоне от 2 до 1000;
W1 - число витков основной обмотки;
r1 - диаметр провода основной обмотки.1. Method of compensation self-induction in intrinsically safe transformers by means of counter-parallel connection of the counter-winding to the main winding, which are placed on a common core, characterized in that for the purpose of full compensation self-induction in the main winding, the number of turns W 2 and the diameter of the wire r 2 counter winding is set in accordance with the relations:
W 2 = W 1 • β;
