Description

As is known, wiring by currents of two directions has a number of advantages over wiring by currents of one direction. In the first case, linear interference is much less pronounced than in the second.

In addition, an increase in transmitter battery voltage to reduce distortion is required to a much lesser extent. Similarly, the transmission rate increases.

The present invention relates to a device for wiring two-way currents.

The essence of the invention is the use of a special relay designed to alternately connect the poles of a linear battery to the midpoint of the differential relay.

The proposed device is simple and requires for its implementation a minimum number of additional devices: namely, two relays and one three-pole switch in two directions, which makes it possible to switch from duplex to simplex circuits by simple switching and vice versa without disturbing the basic circuit.

The drawing shows a diagram of the proposed device.

Linear battery 7, the midpoint of which is grounded, switches on differently (412)

nominal poles for contacts 2 and 5 of the battery relay 4; The measles of the latter is connected to the midpoint 5 of the differential winding of the linear relay 6. The winding of the differential relay 6 is connected via a differential milliammeter 8 to the line 9. The winding JO and the relay b are connected through a differential milliammeter 7 / to a grounded artificial line 72. Local battery 75 is connected via resistance J4 into battery circuit 4 in series with transmitter contacts. Thus, when one of the contacts of the transmitter is stop or working, the current flows through the windings of the relay 4, and the relay is thrown to the contact 2; when all contacts of the transmitter are opened, the current in the relay 4 circuit is interrupted and its measles are thrown by spring to contact 3 of relay 4. In the first case, relay 6 turns on to the midpoint 5 of the differential winding plus battery 7, in the second, minus battery 7. Thus, 9 is always under voltage alternately between a plus and a minus of a battery, i.e., the work will take place in two directions.

From the midpoint 5 of the winding of the relay 6, the current splits, and with a balanced balance in the artificial line, half of the current goes into the line, half through the artificial line into the ground.

When working there may be the following cases:

1. The devices of both stations are on the foot; then the table contact 16 of the transmitter is closed, the working contacts are open. At the same time, the winding of the relay 4 is under current at both stations, as a result of which the measles will be located at the working contact 12. To the wire P at both ends at points 5 the battery plus 7 will be supplied. In the winding 7 the relay 6 and the current wire 9 are not will be. In the windings 10 of the relay 6, the current will flow along the circuit: plus battery 7, pin 2 and relay relay 4, point 5, winding 10, artificial line 72, artificial line earth, battery ground. Linear relay 6 will operate, and its measles will be transferred to contact 77. The chain of the stop electromagnet 18 of the receiver will be closed: a contact on the distributor, a brush of the distributor, a solid ring, contact 77, a switch of the relay b, a stop contact 76 of the transmitter and a battery 13. The stop electromagnet will operate and the apparatus of both stations remain on the foot.

If at one of the stations a key was pressed and a dial was made, then the axis of the transmitter would grip with the engine and the axis would begin to rotate. When this happens, the transmitter stop contact opens. The circuit of the battery relay 4 is opened and its measles is transferred to pin 5; Thus, at the transmitting station to point 5, the minus of the battery 7 occurs, i.e. the coil 7 of the relay 6 and the connecting wire will be connected in series to the batteries of both stations.

The windings 7 will have a current that is twice as large as that in the windings 10, and the relay 6 at the transmitting station will remain at the contact / 7, and at the receiving station it will be transferred to contact 19.

Thus, the chain of the transmitter connected in series with the receiver will be open at both stations: a) at the transmitter - at the stop contact of the transmitter; b) at the receiving station in pin 19 of the linear relay 6.

The anchors of the stop electromagnets will disappear and the axes of the distributors of both stations will be coupled to the engines. The brushes of the distributors on both valves will begin to slide along the contact rings of the distributors, perceiving the pulses given by subsequent closures and openings of the working contacts of the assembled transmitter combination.

When the transmitter contacts close, the relay bark 4 will be transferred to pin 2 and switch on battery 7 to midpoint 5; when the transmitter contacts open, the same measles will be transferred to pin 3 of relay 4 and battery 7 will come to point 5.

In the wire, in the windings of 7 linear relays 6 of both stations, when the mentioned contacts are closed, there will be no current, and relay 6 will have a pin at pin 77, when opened in a linear circuit there will be double current and relay 6 will be pin at pin 19 at the transmitting station and contact 77 at the receiving station. The circuit of the receiving electromagnets will then close, then open, depending on the location of the brush on the distributors, and the transmitted signs will be imprinted on both the transmitting and receiving stations. After transmitting the dialed combination in the transmitter, the stop contact is closed again, the relays 6 of the relay 6 at both stations will close contact 77, and the brushes of the receivers of both stations will stop at the stop contact. Current will pass through the stop electromagnets, their measles will be affected, and the devices will stop. Thus, simplex work is carried out.

When switching to duplex operation, the three-pole switch is moved to the right position. In this position, the following circuits are closed: 1) battery relay circuit: plus battery 13, resistance 14, relay coil 4, transmitter contacts and minus battery 13, operation occurs as in a simplex.

2. The circuit of the control receiver connected in series with the transmitter: plus battery 13, control receiver 21. lever 22 of three-pole switch, transmitter and minus battery 13; work happens on the transfer with the control of their work.

3. Receiver circuit for receiving work from another station: battery 13, lever 23 of three-pole overrider, contact 7 and the switch relay 6, lever 24
