Abstract: The device to electrically connect the rotor winding of a synchronous electrical machine to an exciter comprises at least two pairs of conductors constructed in the form of current-conducting rods, one of the pairs extending from the rotor winding of the synchronous electrical machine towards the exciter, the current-conducting rods of this pair being bent at a right angle and forming plate-like contact surfaces, the other pair of current-conducting rods extending from the exciter towards the rotor of the synchronous electrical machine. The proposed device further includes two current-conducting wedges which are in contact with the bent current-conducting rods, two flexible buses which connect the current-conducting wedges to the unbent pair of current-conducting rods, and two insulation spacers, each supporting a respective current-conducting wedge on the side of its connection to each of said flexible buses.

Abstract: A device for electrical coupling of generator and exciter rotor current leads, made in the form of flexible busbars located in the area of mechanical coupling between said rotors, characterized, according to the invention, in that the end face of the shaft of one rotor is provided with a projection under which said flexible busbars forming an overlapping joint are placed parallel to the shaft axis, said busbars being attached to said projection by means of a clamp embracing said busbars and projection in the cross-sectional plane of the shaft.The present invention relates to electric machines, and more particularly, to devices used for electrical coupling of generator and exciter rotor current leads.Known in the art are devices, wherein the coupling between the generator rotor current lead and the exciter rotor current lead is effected by means of spring-loaded contacts, the contact surfaces whereof are located in a plane normal to the shaft axis.
