Description

The proposed synchronizing device for controlling the mechanisms at a distance consists of the giving and receiving electric motors with interrupters of the collector type and with a special relay intended to close the local chain of the receiving motor when the relay is energized by a signal transmitted from the transmitting station. This additional circuit, activated by the external signal aid relay, can create additional circuits to power the receiving motor in order to increase or decrease the number of revolutions, i.e., in order to obtain accurate synchronization of the operation of both motors. The author assumes that the proposed device will be largely free of the effects of lightning discharges.

In FIG. 1 shows the arrangement of the brushes on the collector of the giving motor; FIG. 2- arrangement of brushes and lamellae on the chopper of the receiving motor; FIG. 3 and 4 is the same, during normal operation, the receiving motor; FIG. 5 - the same, with his backlog; FIG. 6 - the same, when it is ahead; FIG. 7 — the option of switching on a local device to close the lamellae; FIG. 8 - centrifugal switches of local devices. FIG. 4, 5 and 6 should be considered, juxtaposed each of them with FIG. 3

The receiving motor (Fig. 2) is powered via clamps 11 and 12 from a local source of electrical energy. The circuit includes brushes 3 and a collector type interrupter mounted on motor shaft B. Because of this, the supply circuit is interrupted at each motor turn. The chopper consists of a metal rim E mounted on a drum of insulating material and provided with a notch R. Giving motor A (Fig. 1): equipped with the same chopper D, brushes 1 and 2 of which are connected to the relay of the transmitter. Whenever the brushes 1 and 2 slide along the metal rim D and the protrusion 3 at the same time, the relay of the transmitter closes and a signal arrives on the air. The cutout P of the receiver chopper (FIG. 2) is equal in length to the protrusion 3 of the chopper of the transmitting device (FIG. 1).

If the receiving motor is equipped with a receiving device (by wire, or by air) and a relay; locking the local source, then the local battery circuit 4, opened by cutout P (Fig. 2) of the chopper, can be restored by means of an additional lamella W (Fig. 2), closing through the brushes 6 and 7 of the motor circuit in that case, when it is still closed by the LG relay with contact 13. Thus, when the If relay is energized by signals from the outside, it is possible to extend the uninterrupted circuit for the power supply: neither the receiving motor B.

In order to increase the speed of the receiving motor B, depending on the change in the rotational sheet of the giving motor A, the motor interrupter B is equipped with two luminaires E and JKi (Fig. 2), which close the additional supply circuit from the brush 6 to contact 13. brushes 8 - to clip 12, bypassing constant resistance H, inserted into the motor circuit.

In the case of a decrease in the number of revolutions of the giving motor A, the relay M will close the current after the motor B passes the lamella by inertia and feeds through brushes 3 and 4. To decrease the number of revolutions of the receiving motor, the slit is And, due to which the new circuit closes: the motor through the brush 6, then through the brush to the winding 10 of the electromagnet L. Electromagnet L is fixed on a common base with motor B, and the shaft of motor B and the chopper is passed through it. The winding of the electromagnet L through the clamp 9 is connected with the clamp 12. An iron plate is attached to the breaker drum, which is affected by the electromagnet L, and this is what causes the braking. FIG. 3 and 4 of the drawing illustrate the normal operation of the device of FIG. 3 and 5, the lag of the receiving motor; FIG. 3 and 4-runaway him.

For the purpose of smoother deceleration —or accelerating the motor stroke, an additional two or four brushes and lamellae can be introduced, and the resistance and winding of the electromagnet L can be partitioned.

Centrifugal switches can be used to turn on local devices (Fig. 8). (Legend A, BND in Fig. 8 should not be confused with the same designations in Fig. 1 and 2).

The contact in the local circuit is carried out by the fact that at a known number of revolutions the load j8 or B, connected with the collector drum G by means of the spring L, slides over the fixedly fixed metal ring B. The chain closes through the brush: 1, sliding along the metal

the rim A, which connects through the spring M with the load B. The latter, in turn, slides along the rim B, closes the circuit with clip 2. Terminals 1 and 2 are connected to a local fixture circuit, which is desirable to be activated at a set moment. By changing the weight of the weights, lengthening the spring D and increasing the diameter, ring B sets the speed at which the contact will be made.

FIG. Figure 7 shows schematically the option of switching on local devices with the help of alternating signals, which are received when closing the lamellae placed on the collector drum of the giving motor. The signal is received through the lamella 3 and the brush 5. When this circuit closes the receiving relay If (the brush slides continuously), the electromagnet 1 closes its circuit, in addition to the lamella 3 and the brush 5, through terminal 7. In this case, the measles will close the local circuit through pin 9 the instrument to be powered to turn off the instrument. On the transmitting device, the lamella circuit 4 should be closed. In this case, the second electromagnet (Fig. 7) will not crust 8 and thereby interrupt the electromagnet 1 circuit, as well as the device circuit.

The subject matter of the invention.

1. A synchronization device for controlling the mechanisms at a distance from the use of a breaker designed to interrupt the circuit of electrical energy supplying the local motor to a certain part of the revolution each time the motor turns and the relay M designed to close the local circuit of the motor when the relay is energized by a signal transmitted from the transmitting station.

2. With the device indicated in clause 1, the use of weights associated with the collector drum by means of springs and intended for different numbers of revolutions deviate differently from the collector roller and touch the corresponding contacts of the local circuits.
