TIME RELAY

I LIBRARY 1

A relay 15 connected by an IB anode circuit of a threshold element - a 16 p. tiratryn. cold cathode, the grid current of which is limited by resistor 17.

When the alternating voltage is turned on, the time relay starts to operate. 7i and / 2. The opening time of the thyristor 3 is controlled by the phase method within one half-period using a resistor 5.

At the time of the positive half-period of the anode voltage, the capacitor is charged before the voltage of the unlocking of the thyristor 3 during B | rmbni, determined by the constant time of resistors 4 and 5, the capacitance of the capacitor 6,

as well as the rate of increase of the anode voltage.

Starting from the moment of opening up to the end of the positive half-wave of the anode voltage, the current flows through the resistor 7 in the PWM.

Further, this modulated loo kirine iminyjibc stabilizes in amplitude in the stabilizer on the resistor 8 and the zener diode 9 and integrates into the integrator using the resistor 10 and the capacitor 12. Upon reaching

(the values of the voltage on the cover of the capacitor 12 equal to the opening voltage of the thyratron 16 are ignited and the current 15 starts flowing through the winding of the relay. As a result, the relay also activates the time delay and

this ends.

The relay, by its contact 13, through the resistor J4, discharges the capacitor 12 and; below, the gota1VL1I1ivaet of the integrator to the next cycle of accumulation of pulses.

TaiKiHM Oi6pa3iOM, the relative simplicity of the device significantly increases the time delay.

. The subject of the invention is a time relay containing a T-type or pulse mode, a voltage stabilizer, an integrator, an output node consisting of a threshold and an ' 1-element element, characterized in that

(out of time for switching on the actuator, the latitude-emulsifier modulator is connected in series with a voltage regulator and an integrator, the output of which is connected to the input of the output node.
