Definitions

  • the main component of the grinding wheel of a pantograph for electrically powered vehicles is graphitic carbon, to which further metallic components can be added to improve the electrical conductivity.
  • Graphitic 'carbon shows a lower strength against mechanical violent effects, which are not uncommon in the overhead line area.
  • the grinding wheel is anchored in a part of a carrier designed as a holder.
  • the frames usually have a rectangular or trapezoidal shape. Beams including the frames are made of aluminum or galvanized sheet steel. Under certain conditions, e.g. In cross-border train traffic when changing to other power supply networks and when hoarfrost is formed, arcs can form from the contact wire to the wearer, which can lead to their destruction and thus also endanger the mechanical stability of the grinding wheel in the holder.
  • a contact strip which has an electrically insulating material on the outside has a thickness that ensures high dielectric strength.
  • the dielectric strength refers to the electrical field strength related to the material thickness, at which the insulating material is destroyed and its insulating ability ceases.
  • the insulating material is arranged on the outside of the socket or the carrier.
  • the electrically insulating material is applied on the outside by complex flame spraying or plasma spraying. There is also the option of gluing a ceramic or plastic layer to the

  • the grinding device according to the invention for lowerable current collectors of electrically operated vehicles consisting of a carrier connected to a pantograph, on which a grinding body arranged over the length of the carrier is fastened, characterized in that the carrier and the grinding body have a cladding that covers at least the area a grinding surface.
  • the cladding is form-fitting and includes the carrier and the side surfaces of the contact strip. This close-fitting, form-fitting connection between the cladding and the carrier and the side surfaces of the contact strip enables optimum mechanical securing of the contact strip in conjunction with an electrical dielectric strength achieved over the entire carrier to prevent arcing.
  • the refinement of the invention to design the cladding as a clamping sleeve has the great advantage when retrofitting existing grinding devices that this cladding is simply pushed over the carrier and the grinding bodies and because of the clamping effect of the cladding in connection with the shape, a stable fastening is achieved ,
  • the clamping effect can advantageously be supported by attaching suitable mechanically acting clamping aids.
  • the cladding essentially consists of electrically insulating material, the mechanical strength being suitable Choice of materials can be reinforced.
  • polymeric materials such as polyamides, polyetherimides or polyether sulfones have proven to be very advantageous.
  • a further embodiment provides that material combinations are used which above all take into account the fact that the cladding in the area of the grinding wheels is exposed to special mechanical loads. So it is e.g. It is possible to combine additional reinforcement elements or reinforcement materials with the cladding in order to achieve additional stability against the effects of violence, especially in the area of the grinding wheels. Additional reinforcing elements or reinforcing materials can be, for example, suitable fiber materials which are connected to polymers, for example carbon fibers. However, it should be noted that the hardness of the cladding in the area of the grinding wheel must not be greater than the hardness of the grinding wheel material itself.
  • a further embodiment of the invention provides that the cladding has cutouts. These cutouts are provided, in particular, in the area of the carrier, in which a jump over of an arc to the catenary wire is virtually impossible.
