Description

В системах автоматического регулировани  примен ют бесконтактные реле, состо щие из моста посто нного тока, в два противоположных плеча которого введены нелинейные сопротивлени , и усилител , включенного в измерительную диагональ моста.In automatic control systems, contactless relays are used, consisting of a DC bridge, in which two opposite arms are introduced nonlinear resistances, and an amplifier included in the bridge diagonal measurement.

Предлагаемое реле отличаетс  от известных тем, что в измерительную диагональ моста последовательно с индикатором включен вентиль,позвол ющий получать скачкообразное изменение выходной электрической величины (тока или напр жени ).The proposed relay differs from the known ones in that the gate is connected to the measuring diagonal of the bridge in series with the indicator, which makes it possible to obtain an abrupt change in the output electrical value (current or voltage).

Предлагаемое реле (см. схему) выполнено в виде моста, два плеча которого образованы посто нными сопротивлени ми /, а два других - нелинейными сопротивлени ми 2. В измерительную диагональ моста включен усилитель 3 (в данном случае полупроводниковый) последовательно с вентилем 4, пол рность которого должна быть такой, чтобы он срезал верхнюю (положительную) ветвь внешней характеристики мостовой схемы.The proposed relay (see diagram) is made in the form of a bridge, the two arms of which are formed by constant resistances /, and the other two by nonlinear resistances 2. In the measuring diagonal of the bridge amplifier 3 (in this case, semiconductor) is connected in series with valve 4, floor the quality of which must be such that it cuts off the upper (positive) branch of the external characteristics of the bridge circuit.

Использу  в качестве нелинейных элементов 2 моста термисторы и поддержива  питающее напр жение посто нным, можно получить бесконтактное реле температуры. Аналогично может быть создано реле тока, давлени  и т. д.Using thermistors as bridge 2 nonlinear elements and keeping the supply voltage constant, a non-contact temperature relay can be obtained. Similarly, a current, pressure, etc. relay can be created.

Предмет изобретени Subject invention

Бесконтактное реле, состо щее из моста посто нного гока, в два противоположных плеча которого введены нелинейные сопротивлени , и ЗТилител , включенного в измерительную диагональ этого моста, отличающеес , тем, что, с целью получени  скачкообразного изменени  тока или напр жени , в измерительную диагональ моста последовательно с .усилителем включен вентиль, запирающий ток того направлени , который воздикает в.нанале.. пода.чи управл ющего напр жени .A contactless relay consisting of a constant-current bridge, in which two opposite arms are introduced non-linear resistances, and a ZTilitel, included in the measuring diagonal of this bridge, which in order to obtain an abrupt change in current or voltage, in the measuring diagonal of the bridge In series with the amplifier, a valve is turned on, blocking the current of the direction that arises in the channel. The control voltage supply.
