Description

In train lighting installations powered by several dynamos, it is already known to use for adjusting the voltage at the terminals of the lamps automatically changing its value of resistance, and this adjustment is carried out independently of the adjustment of the voltage of the dynamo. The inclusion of the aforementioned resistance is necessary in the case that the car lamps are powered from the dynamo of this car; in the case of battery power, it is short-circuited.

The present invention relates to such a device and consists in a constructive form of its implementation, in which, in the case of attaching an installation to a common highway, the above-mentioned resistance remains on, both during movement and when the train is stopped.

In FIG. 1 is a schematic diagram of the inclusion of the proposed device; FIG. 2 - the complete scheme.

Train lighting installation, consisting of lamps C, is normally powered.

from the dynamo A or from the battery In addition, power can be supplied, for example, in case of damage to the dynamo L, and from the train F, which is followed by the switch O: Switching from battery to the dynamo and back is carried out by an automatic switch Ki, controlled by the core E of the electromagnet with two windings-shunt R and consistent M.

IF this setting is disconnected from the train line F (switch O is in the left position), then when the train is moving, when the dynamo A is working, the winding R excites the electromagnet E, and the latter keeps the switch in the left position; in this case, a battery B and a lamp C are connected in parallel to the dynamo A, and an automatically controlled resistance D is connected in series with the lamps C, for example, a resistance made of carbon disks, a control electromagnet not shown in the drawing, a winding

which is attached to the terminals of the lighting circuit C.

When the train stops, when the dynamo A stops working, the current in the winding / stops and the electromagnet E releases the switch Ki, which is shifted to the right position and short-circuits the resistance D; in this case, lamps C are powered directly from battery B.

If this installation is connected to the train line / - (switch O in the right position), then so that with the dynamo turned off. While lamps C were not exposed when the train was moving to a higher tension, it was necessary to turn on some way again before the lamps C with resistance D.

For this purpose, the wire 1 assigned to short-circuit the resistance / according to the invention switches on the switch L mechanically connected to the switch O so that when the latter is closed, the switch Z is open and vice versa. Then, in the case of the connection of this installation to the highway F, the resistance D will always be connected in series with the lamps C, regardless of whether the dynamo A is working or it is idle.

The winding M of the electromagnet E serves to demagnetize the core of this electromagnet and to release the switch Ki in the case that the current of the reverse direction flows into the dynamo A when the number of revolutions of the battery B decreases.

In order to reduce the equalizing current, which may arise in the case of generator A operating on a common line, an additional resistance N is introduced into the wire 2 connecting the switch O with the battery terminal attached to the switch K (Fig. 2). To shunt it when powering the lamps C from the line, when machine A does not work, instead of switch L, the switch / ,,, is set to two directions. When the switch O is closed, the contact / switch LI connected to the contact d of the switch / Cr is transferred to the contact h of the switch connected to the train main;

when the switch O is open, the contact / is transferred to the contact e connected to the common resistance point D and the lamps C.

To adjust the voltage of machine A, an automatic regulator S of the usual type, driven by an electromagnet A, is used. In order for the switch Ki to operate on the mains supply, it is mechanically connected to the terminals T nI and the end of the winding / connected to contacts 1 and p. When the position of the switch Ki corresponds to the switching off of the dynamo A, the contact / touches the contact T, and when the position of the switch Kg corresponds to the turning on of the dynamo, the contact p touches contact I. The winding R will be included in these cases through the corresponding resistances V and W.

The subject of the patent.
