Abstract: A non-rail-bound vehicle, truck or bus, includes a current collector feeding electrical energy from an overhead line installation having a contact wire. The collector has a contact strip with a working region contacting the contact wire. An actuating device coupled to the collector adjusts the contact strip. The contact strip is horizontal and adjustable transversely to a vehicle longitudinal axis. A sensor senses the position of the vehicle relative to the contact wire. A control device connected to the sensor and the actuating device actuates the actuating device based on the sensed vehicle position, so that the contact strip maintains contact with the contact wire within its working range. The vehicle thus reliably maintains contact with the contact wire through the collector during operation on multilane roadways with an at least partially electrified lane, even at relatively high speeds of, for example, 80 to 100 km/h.

Abstract: A contact line system is provided for traction supply of an electrical tractive vehicle. It contains a contact line being contacted by a current consumer of the tractive vehicle for energy transmission. It further contains a central substation for converting a supply voltage into a contact line voltage which is electrically connected to the contact line via a section exit for supplying of energy. It additionally contains a protection device for interrupting the energy supply upon recognizing a failure which has a central measurement device for measuring a parameter in the section exit and an evaluation device for recognizing a failure. The protection device has decentrally arranged measurement units for detecting parameters outside of the substation and a data transmission system for transmitting parameter measurement values to the evaluation device. The evaluation device evaluates the decentrally detected parameter measurement values for failure recognition.

Abstract: A method is disclosed for detecting the switch position of an isolating switch, or of a grounding switch, wherein a displaceable switching meter is applied to the contact part in the gap of a contact part in the closed switch position, and wherein the displaceable switch meter can be spaced from the contact part in the open switch position. In at least one embodiment, an optical signal is influenced by the switch meter for differentiating the two switch position with a closed switch position. If the optical signal is influenced, it is indicated that the isolating switch, or the grounding switch, is in the closed switch position. Otherwise it is indicated that the isolating switch, or the grounding switch, is in the open switch position.
