Изобретение относитс  к области электрю-г измерительной техники.The invention relates to the field of electrical measuring instruments.

Известны пороговые устройства, содер;; жащие 1лногообмдт6чнЬё пол ризованное реле и выпр митель. Выпр митель включен 5 последовательно или параллельно обмотке реле. Рабоча  точка выпр мител  в таких устройствах находитс  вблизи начала его вольт-амперной характеристики, что при I водит к разбросу порога срабатывани  и Ю i увеличению напр жени  порога.. Known threshold devices, content ;; The actuators are a polarized relay and rectifier. The rectifier is connected 5 in series or parallel to the winding of the relay. The working point of a rectifier in such devices is near the beginning of its current-voltage characteristic, which, with I, leads to a spread of the triggering threshold and a Yi increase in the threshold voltage.

Cheating ps 3 and 4 are connected in accordance with and in series with winding 2. As the alternating current passes through coil 2, they are induced. d. windings 3 and 4, which are summed with the voltage on winding 2. Total e. d. is delivered by the driver 5, as a result of which a forced current flows through the coil; kam 2, 3, 4. An increase in the voltage applied to the rectifier, causes spraying of the par-point on the current-voltage characteristic of the HKe, thereby reducing the scatter; the threshold.
