Abstract
The invention relates to a contact unit and to a method for steering electric arcs on a contact unit, in particular for supplying vehicles with power via an overhead wire (20), the contact unit comprising a sliding contact device (19), the sliding contact device having a contact strip support (21) and a contact strip (22) disposed thereon, the contact unit having a steering device (24) for electric arcs (25) which is disposed on the contact unit, the steering device being provided with a magnet (30).
Claims16
A contact unit, in particular for supplying vehicles with power via an overhead wire (20), the contact unit comprising a siding contact device (19, 35, 37, 43, 44, 54), the sliding contact de-vice having a contact strip support (21) and a contact strip (22, 45, 55) disposed thereon,
- characterized in that
- the contact unit has a steering device (24, 36, 38, 48, 59) for electric arcs (25) which is disposed on the contact unit, the steering device being provided with a magnet (30, 39, 49, 60);
- and
- the magnet (30, 39, 49, 60) is disposed on a support profile (23, 46, 56) of the contact strip support (21), wherein an electric arc (25) from the overhead wire can be deflected from the support profile and be steered toward the contact strip (22, 45, 55) or be extinguished.
A method for steering electric arcs (25) on a contact unit, in particular for supplying vehicles with power via an overhead wire (20), a contact strip support (21) having a contact strip (22, 45, 55) of a sliding contact device (19, 35, 37, 43, 44, 54) of the contact unit disposed thereon is brought into contact with an overhead wire by means of a positioning device of the con-tact unit, an electric arc being formed between the overhead wire and the contact strip,
- characterized in that
- by means of a steering device (24, 36, 38, 48, 59) of the contact unit which is provided with a magnet (30, 39, 49, 60), the electric arc is extinguished or is steered toward the contact strip and makes contact with the contact strip;
- and
- the magnet (30, 39, 49, 60) is disposed on a support profile (23, 46, 56) of the contact strip support (21), wherein the electric arc (25) from the overhead wire can be deflected from the support profile and be steered toward the contact strip (22, 45, 55) or be extinguished.
A use of a magnet (30, 39, 49, 60) for steering or extinguishing electric arcs (25) on a contact unit, in particular for supplying vehicles with power via an overhead wire (20), the contact unit comprising a sliding contact device (19, 35, 37, 43, 44, 54) which has a contact strip support (21) and a contact strip (22, 45, 55) disposed thereon and a positioning device for holding and positioning the sliding contact device, the magnet forming a steering device (24, 36, 38, 48, 59) for electric arcs and being disposed on a support profile of contact strip support of the contact unit;
- wherein the electric arcs (25) from the overhead wire can be deflected from the support profile and be steered toward the contact strip (22, 45, 55) or be extinguished.
