Abstract

The invention relates to mobile power supply systems. The purpose of the invention is to increase electrical safety. The power is supplied to the additional contact brushes 13 from the battery via additional buses 23 and insulated wires. Electric current from brushes 13 is supplied to an intermediate relay coil, which is installed in a sealed enclosure 11, where there is also a magnetic starter, in the coil circuit of which the relay contacts are closed and which connects power contact brushes 6 to cable line 1. From brushes 6 through buses 22 and the cable is powered by the consumer. The current collector 18 moves along the guide rails on the rollers 16 and is held by the rollers 17. When the tires 22, 23 come into contact with the brushes 6, 13, the latter are de-energized as the relay circuit opens. Cable line 1 is always connected to the consumer, since the distance between the supports is less than the length of the current collector 18. 3 Il.

Description

The invention relates to electrical engineering, namely to power supply systems of mobile consumers.

The purpose of the invention is to increase electrical safety.

On Fig presents the proposed device, General view; FIG. 2 is a section A-A pa of FIG. on Fig - section bb in Fig, 10

The device contains a cable I transmission line connected to the terminal assembly 2 connected to the magnetic starter 3, which through the power cable connecting wires 4 is connected to the brush holder 5, in which the contact brush 60 is attached. Under the holder 5 there is a spring 7, which rests on the second end of the insulating the yoke 8, in which the holder of the 5 is secured, and the yoke

Sa 8 is attached to a metal beam 9 located on support 10, on which a hermetic case -11 is mounted, inside of which there are

a magnetic starter 3 with a terminal assembly 2 and an intermediate relay 12 connected to additional contact brushes 13 by means of insulated wires 14. Guides 9 are fixed on beam 9, and a current collector 18 is mounted on them with the help of guide rollers 16 and retaining rollers 17, consisting of two end carriages 19 and an intermediate carriage 20, they are secured by means of insulating gaskets 21 current-carrying power tires (skis) 22 and additionally connected to running tires (skis) 23, respectively connected to

a mobile consumer using a power cable 24 and with a battery located on the mobile consumer, wires 25 a

the daily trolley 20 is located node 26 of the articulation of the current collector 18 with a movable consumer .:

The device works as follows,

Using the switch, the battery circuit is closed and the power is supplied via insulated wires 25 to additional current-carrying busbars (skis) 23; Since the conductor is designed in such a way that the distance between the supports 10, on which insulating crossbars 8 with contact brushes 6 and 13 are installed, is less than the length of the tires 22 and 23 of the attachment 18, the tires 22 and 23 are always in contact with the contact aunts 6 and 13 and the electric current through additional contact brushes 13 and insulated wires 14 is supplied to intermediate relay 12. Intermediate relay 12 closes its contacts in the coil circuit of the magnetic actuator 3, which connects 1 contact brushes 6 to each patient’s line lovye bus 22 and power cable 24, power is supplied to the mobile user, the user moves movable, and with it dvizhems mechanically coupled by uzlg. 26 articulate the current collector 18 along the guide rails 15 on the guide rollers 16 o

When the tires 22 touch the brushes 6, they are pressed by the tires 22, and the brushes b act with the help of springs 7 on the current collector 18, but it does not rise as it is held by the rollers 17. When the tires 22 and 23 come off the brushes 6 and 13, the chain , through which the intermediate relay 12 is energized, and the contacts of the relay 12 are opened in the coil circuit of the magnetic actuator 3,

which disconnects the cable line 1 from the power contact brushes 6.

During movement, the current collector 18 contacts alternately with groups of contact brushes 6 and 13 and the tires 22 and 23 of the current collector 18 are always in contact with the brushes 6 and 13, since the length of the tires 22 and 23 is greater than the distance between the supports 10 on which the brushes are located 6 and 13.
