A current collector has a sliding contact for making electrical contact with a conductor profile of a conductor line and an antenna for insertion into a longitudinal slot, running in a longitudinal direction of the conductor line. The sliding contact and the antenna can be moved jointly towards the conductor profile in a feed direction by a feed device of the current collector. A conductor line has a conductor profile running in a longitudinal direction, having an elongate cavity and a longitudinal slot adjoining the cavity and running in the longitudinal direction. The conductor profile has at least one sliding contact groove for the sliding contact of the current collector. The antenna is mounted on the current collector so as to be moveable with respect to the sliding contact in the feed direction, and the conductor profile has at least one spacer slide surface running in the longitudinal direction, for a spacer slide of the current collector.

A slidable current collector has an array of terminals with carbon brushes for contacting conductor rails to deliver electrical power to a moving work machine. The terminals have upper sections with a conductive post, lower sections that include a reservoir of liquid metal, and bladders that connect the upper sections with the lower sections. Magnets surround outer shells of the terminals. Fluid above a threshold pressure fed into the bladders holds the upper sections apart from the lower sections and forces the magnets away from the conductor rails. Fluid below the threshold pressure allows the magnets to clamp the terminals to the conductor, lowers the conductive post into the liquid metal, and urges the carbon brushes against the conductor rails. The bladders provide a fluid suspension distributed across the array of terminals, enabling consistent electrical contact and wear for the carbon brushes.

A method for manufacturing a current collector head for a current collector consisting of an electrically conductive contact shoe and an electrically insulating contact shoe holder includes the following steps: inserting a section of the contact shoe into an outwardly open cavity in the contact shoe holder dimensioned to match this section; clamping the contact shoe in the cavity of the contact shoe holder by acting on the contact shoe holder with at least an external force directed onto the inserted section of the contact shoe; heating the contact shoe to a temperature sufficient to form a bonded connection with the contact shoe holder; and cooling the current collector head formed from the contact shoe and the contact shoe holder.

The present invention relates to the technical field of train power supply and operation control, and provides a three-rail power supply control system for an electrical railway train. Power supply rails in the system are divided into a first power supply rail, a second power supply rail, and a third power supply rail, wherein the first power supply rail, the second power supply rail, and a running rail constitute a three-phase AC power supply loop, and the third power supply rail and the running rail constitute a DC power supply loop. An AC-DC-AC variable voltage variable frequency device supplies power to a train traction motor by means of the three-phase AC power supply loop and current collectors. Frequency modulation and voltage regulation power supply is conducted by means of the AC-DC-AC variable voltage variable frequency device on the ground to achieve train driving and operation control. The DC power supply loop is powered by means of a rectifying device on the ground, and power is supplied to auxiliary electric equipment of the train by means of the current collectors. By changing the power supply mode of the system and optimizing the system structure, the weight and axle load of train-mounted equipment are effectively reduced, lightweight of the train is achieved, and the bearing efficiency of the train is improved, and moreover, automatic control and unmanned driving for train operation are achieved in the most economical way.
