Current collector
A device provides the process of transmitting electricity through a sliding contact.
The current collector must ensure the transfer of current through a sliding contact up to 3.2 kA per rail lines that electrified on direct current with a voltage of 3 kV and up to 1.2 kA - on alternating current with a voltage of 25 kV.
The main requirement for the current collector is to ensure stable pressing in the sliding contact, since an increase in pressing leads to increased mechanical wear. A decrease leads avulsions, i.e., to increased electrical wear of the contact wire and current collecting elements.
Similar functions perform current collectors urban ERS.
The advantages of our current collectors:
- Permissible continuous current 3200A;
- Low reduced mass;
- High transverse and longitudinal stiffness eliminate resonance phenomena during the movement of ERS;
- An opportunity of using on ERS with speeds of up to 160 km/h;
- Exploitation in the temperature range from -50 to +50 °С;
- Low life of cycle cost.

The top node, which includes two three-row runners, allows you to shoot current up to 3200 А.

The top node, which includes two three-row runners, allows you to shoot current up to 2400 А.

Equipped with automatic lowering systems, which are triggered when the current collector is raised to a height of more than 7000 mm above the railhead level. Besides, they are triggered when the runner inserts begin to collapse.

The control panel of the current collector is located in the body of the ERS. Equipped with automatic lowering systems, which are triggered when the current collector is raised to a height of more than 7000 mm above the railhead level. They have a small size (no more than 340 mm) in the folded position.

The removable current has up to 800 A when moving and up to 250 A in the parking place, from a contact network with a voltage of 27 kV and an ERS speed of up to 155 km/h.

The removable current has up to 1200 A when moving and up to 300 A in the parking place, from a contact network with a voltage of 3000 V DC and 27 kV AC and speed of ERS movement up to 160 km/h.

The maximum admissible continuous current is up to 800 A when moving at speeds up to 90 km/h or up to 160 A when parked. The nominal voltage of the overhead contact system is 550 V.

Current-collector system
A current collector for railway electric rolling stock consists of the following elements:

Serve to mount the current collector on insulators mounted on the roof of an electric rolling stock.

Is the moveable part of the current collector, which provides vertical movement of the runner and transmits the pressing force from the lifting mechanism to the runner of the current collector.

Is a spring borne upper node of the current collector, interacting with the contact wire.

Is a runner's element, which provides a sliding contact on the wire.

Is a сurrent collector element, which provides the cushioning of the runner relative to the frame.

Serve for lifting the runner from the folded position to the contact wire and taking over the loads acting on the runner.
