Description

one

The invention relates to the field of automation and remote control and can be used, for example, to control the command relays for liquid and gas level controllers. ,

A integrating device containing an integrating capacitor with IK resistors connected to it, two thyratrons, whose cathodes are connected to one of the terminals of the integrated sitnal through the terminals of the integrated sitnal, are connected to the integrated capacitor; the capacitor and the cathode of another thyratron. The anodes are connected to the second terminal of the integrated signal and the contacts of the command relays through the windings of the controller's control relays.

However, such a device contains two thyratrons, the ignition voltage of which may not coincide, and two charging resistors, the nominal values of which also have a scatter. As a result, the charge time of a capacitor is not the same for signals of different polarity, which greatly reduces the integration accuracy.

The aim of the invention is to improve the accuracy of integration of alternating-wave signals.

This goal is accomplished by the fact that the integrating device is made on a single Shirak

The grid of which is connected to the output of the charging resistor and through the contacts of the intermediate relays of the zero-organ regulator. Connected to the terminals of the charging capacitor, which are connected by other contacts of the intermediate relays to the luminous source minus. The cathode of the thyratron through the windings of the control relay of the regulator is connected to the terminals of the charging conductor, and the anode of the thyratron and the other output of the charging resistor are connected. with a plus power source.

The drawing shows the principal electrical circuit of the proposed device.

The device contains a thyratron /, the grid of which is connected via the charging resistor 2 to the positive power source, and through contacts 3 and 4 intermediate regulator null relay to the capacitor 5 plates. The cathode of the thyratron is connected to the controller through windings 6 and 7 the capacitor plates 5 and. through the contacts 8 and 9 of the intermediate relay of the zero-organ controller to the minus of the power source. Thyratron anode / .connected to the positive power source.

The device works as follows.

When the contacts 3 and 9 of the intermediate relay of the Zero-organ regulator are closed, resistor 2, contact 3, capacitor 5 and contact 9 receive the charge current of the capacitor o. In addition, the charge of the capacitor 5 is applied to the grid of the thyratron 1. If the polarity of the signal does not change frequently and during the closing time of the contact 3, the capacitor 5 will charge before the ignition voltage of the thyratron /, the thyratron 1 opens and the command relay 6 is activated If the circuit is triggered as a delay unit.

If the polarity of the signal changes relatively frequently, the voltage on the condenser 5 during the closing time of contact 3 does not rise to the opening voltage of the thyratron 1. When the contacts 4 to 8 close, another intermediate relay of the zero-organ regulator minus the charge of the capacitor 5 is connected to the resistor 2, and plus the charge of the capacitor 5 - to the minus of the source of the lithium. Through the resistor 2, pin 4, capacitor 5 and pin 8, a current flows.

| If the duration of the signals of different polarity is not the same, a charge of a certain polarity accumulates on the capacitor 5, plus which is applied to the grid of the thyratron 1 only at the moment when the dominant signal arrives at the input. When the capacitor 5 is charged before the ignition voltage of the thyratron /, the thyratron 1 at the moment of the arrival of the dominant signal opens and the command relay of the regulator 6 or 7 is activated, depending on the polarity of the dominant signal.

The selection of the controller relay of the controller is made by contacts S and 5 from the intermediate relays of the zero-organ controller.
