Description

block A

The invention relates to telemechanics and can be used for remote control of dispersed objects.

The purpose of the invention is to simplify the device and increase reliability.

The drawing shows a schematic diagram of the device.

The device contains two-position relays 1-4 with self-holding, capacitor 5, thyristors 6 and 7, diodes 8 and 9, resistor 10, diodes 11 and 12, control buses 13 and 14, capacitor 15, contact sensors 16-18.

The device works as follows.

To turn on turnip 1, you need a minus power source (not shown) to apply to the control bus 13, and

plus - to bus 14. This turns on thyristor 6 along the circuit: plus power source - bus 14 - diode 9 - resistor 10 - control electrode of thyristor 6 - bus 13 - minus power source. Thyristor 6 is unlocked and the first (including) relay 1 winding and the second (switching off) relay 4 winding are connected along the circuit: plus power supply source - bus 14 - diode 12 - capacitor 5 - first relay winding 1 and second relay 4 - disconnecting contact 4 relays 4 - thyristor 6 - bus 13 - minus power supply. In addition, the capacitor 15 is charged, connected in parallel with the first winding of the relay 1 and the second winding of the relay 4.

Relay 1 is turned on and relay 4 is turned off. Relay 1 turns on an actuator (not shown) that closes contact sensor 16 in the second winding circuit of relay 1, and relay 4 opens its contact 4, and the core of the contact system 4 does not hang (even when contact 4 can open at the intermediate position of the relay core 4) due to the discharge of the capacitor 15 to the second winding of the relay 4, which allows a clear operation of this relay.

As the capacitor 5 is charged, the windings of the relay 1 (on) and relay 4 (off) are de-energized, and the thyristor 6 is locked. At the same time preparing

is the switching circuit of relay 2. i

voltage applied to the busbars (polarity changes can be made with a contact and contactless switch). In this case, relay 2 is turned on and relay 1 is turned off. When this happens, the recharging of the capacitor 5 occurs. In the following, the device operates in a similar way.

Thus, when the supply voltage changes polarity, information is advanced to the next relay.
