Description

(током намагничивани  можно пренебречь, так как достаточно просто выполнить схему таким образом, чтобы этот ток был на пор док меньше тока IH.T. ) на обмотках трансформатора 1 по вл етс  напр жение, которое через выходные клеммы поступает на исполнительный орган.(the magnetizing current can be neglected, since it is enough to simply carry out the circuit so that this current is an order of magnitude less than the current IH.T.) There is a voltage on the windings of the transformer 1, which through the output terminals goes to the actuator.

В качестве выходной обмотки может использоватьс  люба  имеюща с  или любое количество дополнительных обмоток. Дл  ограничени  напр жени  на обмотках трансформатора при срабатывании датчи/I -. I Any output winding or any number of additional windings can be used as the output winding. To limit the voltage on the windings of the transformer when the / i switch is triggered. I

Таким образом, поскольку напр женно на обмотках трансформатора равно нулю в нормальном режиме работы, то его масса н габариты могут быть уменьнгеиы. Формула изобретени Thus, since the voltage on the windings of a transformer is zero in normal operation, its mass and dimensions can be reduced. Invention Formula Трансформаторный датчик тока, содержащий трансформатор, первична  обмоткаTransformer current sensor containing a transformer, primary winding которого включена в цепь измер емого тока , и источник онорпого сигнала, подключенный к вторичной обмотке с выходными клеммами дл  подключени  к исполнительному элементу, отличающийс  тем, что, с целью уменьщени  массы и габаритов , источник опорного сигнала выполнен в виде источника тока, вторична  обмотка трансформатора включена таким образом, что ток, развиваемый этой обмоткой, направлен встречно току источника тока, а выходные клеммы датчика подключены к зажимам вторичной обмотки трансформатора .which is connected to the measured current circuit, and the onorp signal source connected to the secondary winding with output terminals for connection to the actuator, characterized in that, in order to reduce the weight and size, the reference signal source is a current source, the secondary winding of the transformer included in such a way that the current developed by this winding is directed oppositely to the current of the current source, and the output terminals of the sensor are connected to the terminals of the secondary winding of the transformer.
