Description

Devices are already known for selectively turning on receivers of electrical energy, equipped with a series of electromagnets, each of which is driven by the sending of current pulses and at the same time prepares a circuit for sending pulses and actuating the next order electromagnet. The present invention relates to such a device and consists of its constructive implementation.

In FIG. 1 shows a section through a switch installed in each of the receivers of electrical energy serviced by the device; FIG. 2-diagram of the electrical connections of the device.

The device consists of a series of switches K, each installed at the respective receivers x of electrical energy and interconnected by three wires a, b, h. The device is controlled from a central switch, which has a current interrupter G and a three-pole switch 0, connected in series in source chain Z; one of the poles of this current source is grounded. The handle of the key O can rotate on its axis in a horizontal plane in order to install it over one of the contacts, y, y, and t, from

the first of which is connected to the conductor. The second is connected to the conductor b and the third to the conductor a. In addition, to close one of these contacts, the handle of the key O can be moved in a vertical plane.

Switches K, installed at receivers D, each consist of two electromagnets A, B (or, respectively, A and 5), equipped with a common bark L, completed in the form of a rocker arm swiveling on the axis O with three contact levers e, JK, h; on the lid of the switch K are placed curved in an arc of a circle with a radius equal to the length of the contact levers, contacts H, P, closed by the end of the lever 3, -contacts C, F, guide, closed by the end of the lever, and contacts, w, c and d the end of the lever e. Contact plate g is grounded on all switches. The diagram (Fig. 2) shows three switches K as an example, however, their number can be increased if necessary.

To activate the D-electric energy receiver (the latter according to the scheme), the key O is installed above the contact y and it is pressed, as a result of which the electromagnet L. circuit of the first switch will be closed: ground, battery Z, interrupter winding G, chopper pin, contact lg connected to the handle of the key About contact y, wire, contact C, winding of the electromagnet A, contact g connected by a lever g to the contact plate d, ground. The anchor L of electromagnet A, together with the contact levers e, g, vi, z, is rotated clockwise, while opening its lever (its contacts in the guide) and its lever e and the contacts in the circuit of the electromagnet B.

In addition, the contact lever will overlap / ZIN, thereby connecting receiver D. to the wire. Due to the transfer of lever w from the contacts guide to contacts C and F, the contact at the key Оi on the central switch will be connected via wires a and "1 electr 5 magnet A. On the other hand, this electromagnet through the contacts of its guide

switch is connected to ground. One time with the action of the first switch just described, the breaker G pulls in its measles, short-circuits the battery Z shortly (via contact w) and thereby disconnects the Q key from this battery. When the key is released, the O- short circuit of the battery Z is automatically disconnected, and the choke of the chopper moves back to the contact l :.

The second pressing on the key O in contact J / closes the electromagnet J. circuit of the second commutator, and the contact levers e, f of, fixed on its core L, are also turned clockwise; as a result, the receiver connects to the h wire, turns off the electromagnet A, prepares the electromagnet circuit and closes the O nF contacts, through which the winding of the electromagnet A of the third switch connects to the y contact by wires a, ai, and 02.

Consequently, the electromagnet A, in the same way as it was described with respect to the electromagnet A, will be prepared for action, since its winding is connected to earth via contacts on the other side. The interrupter Rc works, as in the first case, and disconnects the contact from battery Z during actuation of electromagnet A. When sending a third pulse, it is completely analogous to CPA / electromagnet A and receiver L via contacts / and, closed by lever 3, will be connected to the wire hours.

This position of the device makes it possible to simultaneously activate all the receivers D, D and 2, since they are all connected to the wire h. For this purpose, the key O must be installed above the contact and connected directly to the non-grounded pole of the battery Z (besides the interrupter D that is not shown in the drawing). When lowering the key O after this, all the receivers will be connected to the battery circuit Z parallel through the ground (or in some other way) and, therefore, will come into effect. Electromagnets of telegraph devices, telephones, electrical signaling devices, etc. can be used as receivers.

If only one receiver is required to be activated, for example, as mentioned at the beginning of the description, the third, then the switches of the first and second receivers must be previously brought to their original position (Fig. 2), the contacts and and p both of them must be open, which is carried out with the help of electromagnets D B, etc. The windings of each of these electromagnets, after turning the corresponding rocker arms clockwise on one side, are connected to earth through contacts -and and g (closed by lever e), and on the other hand On the other hand, to the contact of your switch. Therefore, when the key O is pressed, after installing it over contact t, only electromagnet B of the first switch comes into effect, the contact of which is connected directly to contact t. Electromagnets 1, B of other switches cannot be activated, because their contacts are currently contact tp not connected. The electromagnet B, having worked, will turn the beam L counterclockwise, as a result of which the receiver will be disconnected (in contacts / and I) from the wire h and, moreover, the contacts w will be closed. Through these contacts, wires b and b connect and are connected to the contact of the second switch and, therefore, electromagnet B can already be activated by sending the next current pulse. The circuit of electromagnet B at the time of its processing is interrupted by the chopper ring G, Sending the second impulse through wires b, 6i activates the electromagnet B, after which only the receiver remains connected to the wire h.

Thus, by sending pulses from the central switch, either only one receiver or any number kx can be switched on. The devices are reset to their original position after the transmission of certain messages to the selected receiver (if the receiver is, for example, a telegraph or telephone) by sending another impulse by wire B, which actuates the corresponding electromagnet B. In all cases of transmission energy receivers on the wire h chopper G turns off.
