Description

. -

The invention relates to a pulsed technique, namely, relays) M of a hardened frame, which generates pulses of a certain duration when the supply voltage is turned on.

According to the main author. St. No. 488318, a device containing two stages on two electromagnetic turnips is known, with the first cascade containing the first relay biopump, in series with which a resistor and opening of the second cascade are disconnected, the relay is shunted by the first cascade contacts, the second cascade contains the winding the second relay, after $ 5 with which the resistor is connected. and zamshayushie. contacts rale of the first cascade, resistor shunted zamg. with the kayushi contacts of the second KaiDxa relay and, moreover, the winding of each relay is shunted by the corresponding code sensor 1 J.

The disadvantage of the known pulse generator is that at

A row of a capacitor is connected to the winding of the relay, and the clamping capacitor locks the charging capacitor. This reduces the efficiency of the generator, requires the generation of high-power resistivity, imposes a restriction on the value of the radiation resistance of resistor, and the generator has an insufficient range of generation frequencies.

The circuit of the invention; - increasing the efficiency of the generator and extending the frequency range of the general generator. The goal is achieved by the fact that in the pulse generator, the follower of each of the two relays is connected to the opposite direction.

The drawing shows lindipiff the diagram of the proposed pulse generator

Sob.

The electromagnetic relays 1 and 2 are generated. The psnib 1 is switched on to source 3 via a dynistor 4, a resistor 5 and disconnects pin 6 of relay 2, and the relay 2 is connected to the same power source via dyno

torus 7i resistor 8 and closing contact 9 of relay 1. Mountain ridge 5 is shunted by closing contact 10 of relay 1, resistor 8 is shunted by closing contact 11 of relay 2. Relay windings 1 and 2 are connected after 4 by 7 capacitors 12 and 13, respectively.

The generator works as follows,

When the voltage is switched on with a delay, relay 1 is triggered. In this case, the stopping time is determined by a capacitor 12, a resistor 5, a dynistor 4. The turn-on voltage of the relay 1 is determined by the turn-on voltage of the dynistor 4. After the relay 1 is triggered, power supply voltage and contact 9 this voltage is applied to the winding of relay 2. Relay 2 is turned on; the signal is decelerated by the charging time of capacitor 13 Ca, the resistance value of resistor 8 and dynistor 7. The winding circuit of relay 1 is broken by relay b of relay 2 Relay 1 ochivaets and the cycle of operation is repeated.

Since the currents do not flow through the coil of the relays until the switching on of the given nistors, this causes an increase in the efficiency of the device. Turning on the dynisters at the same time allows the operability of devices in the low-frequency region. When the resistance of resistors decreases, the generation frequency increases. Consequently, in comparison with the known prev (The lagged device has an extended generation frequency range.
