Description

Известны реле времени, состо щие из электронной лампы и контура RC в цепи сетки лампы. Регулировка времени подобных реле производитс  изменением сопротивлени  контура RC.Time relays are known, consisting of an electron tube and an RC circuit in the lamp grid circuit. The timing of such relays is made by varying the resistance of the RC circuit.

Предлагаемое устройство отличаетс  от известных тем, что, с целью получени  необходимой выдержки времени в функции параметров какого-либо процесса, сопротивление R измен ют параллельным подключением сопротивлений, вводимых контактами реле по заданной программе.The proposed device differs from the known ones in that, in order to obtain the necessary time delay as a function of the parameters of any process, the resistance R is changed by parallel connection of the resistances introduced by the relay contacts according to a given program.

Принципиальна  схема программного реле времени приведена на чертеже.A schematic diagram of the software time relay is shown in the drawing.

В цепи управл ющей сетки лампы / включен контур RC, состо щий из конденсатора 2 и магазина сопротивлений 5. Сопротивлени  3 соедин ютс  параллельно с помощью контактов 4, которые замыкаютс  по заранее заданной программе в функции параметров протекающего процесса , например температуры нагрева тела, усили , развиваемого при прессовании и т. п.In the control grid circuit of the lamp / circuit, RC is turned on, consisting of capacitor 2 and resistance box 5. Resistance 3 are connected in parallel by contacts 4, which are closed according to a predetermined program as a function of the parameters of the flowing process, for example developed by pressing, etc.

После набора сопротивлений 3 размыкаетс  контакт 5. Конденсатор 2, ранее зар женный до напр жени  запирани  лампы 1, разр жаетс  на сопротивлени  3. Врем  разр да конденсатора 2 до порога огпирани  лампы 7 зависит от общего сопротивлени  магазина сопротивлений . После отпирани  лампы / срабатывает выходное реле 6.After the set of resistances 3, contact 5 is opened. Condenser 2, previously charged before the voltage of locking lamp 1, discharges to resistance 3. Discharge time of capacitor 2 to the threshold of protection of lamp 7 depends on the total resistance of the resistance box. After unlocking the lamp / the output relay 6 is activated.

Описанна  схема цифрового программного реле времени может найти применение при автоматизации различных технологических процессов в химической и других отрасл х промышленности, где требуетс  частое изменение параметров времени.The described scheme of a digital software time relay can be used in the automation of various technological processes in the chemical and other industries that require frequent changes in the parameters of time.

Предмет изобретени Subject invention

Программное реле времени с измен емой в зависимости от режима протекающего технологического процесса выдержкой времени, состо A software time relay with a time delay depending on the mode of the flowing process,
