Abstract
Изобретение относитс к электротехнике и может найти применение в устройствах измерени тока электрических машин. Целью изобретени вл етс упрощение и повышение стабильности характеристики. Трансформатор посто нного тока выполнен в виде магнитного усилител на двух сердечниках 1, 2 с рабочими обмотками 3, 4 переменного тока и обмотками 5, 6 смещени , включенными через реостат 9 в цепь источниками питани 10. Падение напр жени на реостате 9 выполн ет функции опорного напр жени дл установки нулевого сигнала на выходе при отсутствии тока в измер емой цепи 12, чем достигаетс упрощение и снижение потерь энергии. Зависимость опорного напр жени от изменени тока смещени , про вл юща с в виде отрицательной обратной св зи, повышает стабильность характеристики "вход-выход" устройства. 1 ил.This invention relates to electrical engineering and can be used in current measurement devices for electric machines. The aim of the invention is to simplify and increase the stability of the characteristic. The DC transformer is made in the form of a magnetic amplifier on two cores 1, 2 with operating windings 3, 4 of alternating current and bias windings 5, 6 connected through a resistor 9 into the circuit with power sources 10. The voltage drop across the rheostat 9 serves as a reference voltage to set the zero signal at the output in the absence of current in the measured circuit 12, thus achieving a simplification and reduction of energy loss. The dependence of the reference voltage on the change in bias current, manifested as negative feedback, increases the stability of the device's input-output characteristics. 1 il.
