Description

The invention relates to the power supply to a consumer of rolling stock and can be used to power trolley drives used, for example, for interoperational transmissions.

The purpose of the invention is to observe electrical safety.

The drawing shows a schematic diagram of a device for powering a moving object.

The device contains a current collector 1, paired insulated contact elements 2 with contacts 2.1 and 2.2.3 with contacts 3.1 and 3.2, 4 with contacts 4.1 and 4.2, 5 with contacts 5.1 and 5.2 and 6 with contacts 6.1 and 6.2, intermediate relay 7 with contact 7.1, 8 with contact 8.1, 9 - with contact 9.1, 10 with contact 10.1, 11 with contact 11.1, the first terminals of which windings are connected to contacts 2.1-6.1, respectively, and the second terminals - to the negative pole of the power source, which it is in turn grounded and connected to the rails (not shown) with movable parts mounted on them volume (not shown); key elements 12-16, multipurpose switch 17 with closing contacts 17.1 - - 17.5, control bus 18, isolation diodes 19-23, control bus 24, respectively, and thyristor anodes are connected to the positive pole of the power supply, which through current-limiting resistors 25-29 and in series with them the corresponding closing contacts 7.1-11.1 of the intermediate relays are connected to the control terminals of the corresponding valve elements, the electric motor 30 of the displacement drive installed on the object, the closing contact 31-34 s power contactors.

The system works as follows. Before applying the switching-on impulse signal to the control bus 18, the location of the moving object is preliminarily determined and the non-switch 17 sets the address of the signal, which must correspond to the contact elements 2.1-2.2, 3.1-3.2, 4.1--4.2, 5.1-5.2 closed by the current collector 1, 6.1-6.2.

Before applying a pulse signal to the control bus 24, the possibility of safely supplying the pulse potential to the contact elements 2.2--6.2 is pre-established visually.

Let the moving current collector 1 be in contact with contact elements with contacts 2.1-2.2, 3.1-3.2. The switch 17 is set to a position in which its contact 17.1 is closed. An impulse of positive potential is applied to the pin 18, which through

contact 17.1, contacts 2.2 2.1, 2.2-3.1 goes to the 7.8 pe.ie coils. When these pe are switched on, i.e. contacts 7.1 and 8.1 are closed, supplying a positive potential

through the current limiting resistors 25, 26 to the control terminals of the key elements 12, 13, which open and form the supply circuit of the windings 7, 8 of the relay through the key elements 12, 13. Thereafter, the turn-on signal pulse is removed from the strip 18.

The closure of the contacts 31, 32 or 33, 34 turns on the electric motor 30 of the drive for moving an object, with which the current collector 1 moves, for example, in the direction of the contacts 6.1-6.2. When the current collector I comes off the contacts 2.1-2.2, the winding of the relay 7 is de-energized, and the key element 12 is closed. When running the current collector 1 on the contacts 4.1-4.2, the relay 9 is turned on by closing contact 9.1

0 is fed through a resistor 27 with a positive potential to the control terminal of the key element 14, which opens. With further movement of the object, the operation of the system is similar to that described above.

Thus, under a constant voltage after the process of switching on, only those contact elements that have direct contact with the current collector are located, this enhances safety, and exclusion from the end system

Q switches increase its reliability and serviceability.
