Description

При Ij I на рыходе усилител  2 по  вл етсй отрицательное напр жение, которое открывает транзистор 3 и ключевой диод 5. От источника 6 тока компенсации ток компенсации через ключевой диод 5 и транзистор 3 течет навстречу измер емому току I j. По электроизмерительному прибору 1 протекает разность токов 1 - Ь- Вклйчёнйё иёто Й1 ка 6 тШ1 ф;ШЕйсации происходит йртйёЗйШтемьном превышении напр жени  над выстав№ёШъШпЪрйгс м , что позвол ет получав стабильную разность токов в электроизмеритель-.When Ij I at the output of the amplifier 2, a negative voltage appears that opens the transistor 3 and the key diode 5. From the compensation current source 6, the compensation current through the key diode 5 and transistor 3 flows towards the measured current I j. According to the electrical measuring device 1, the difference in currents 1 - b is switched on and the voltage is 6 tSHF; SHEISING occurs when the voltage in the electric meter is stable over the electric current.

; ном приборе 1 при многократном превышении; device number 1 with multiple exceeding

измёр: емого трка.measured: skimming string.

По влшие отрицательного напр жени  на выходе усилител  2 включает цепь 7 сйгназтйзации перегрузки, что позвол ет контролировать момент срабатывани  устройства защиты.Having a negative voltage at the output of the amplifier 2 turns on the circuit 7 to overload the overload, which allows controlling the instant of operation of the protection device.
