Abstract
A system and method to ensure a sufficient amount of electrical energy is supplied to a cable-drawn vehicle of a transportation device. Electrical loads of the vehicle are supplied with power outside a station by an electrical energy store of the vehicle or by both an electrical energy store and the generator during a first movement phase, in which the vehicle is accelerated to a limit speed or, conversely, decelerated from a limit speed into a station. In a subsequent second movement phase, the vehicle is supplied with electrical energy by the generator while the vehicle moves at a speed that is greater than the limit speed.
Claims14
A method for operating a cable-drawn transportation device, by which at least one vehicle that is coupled to a driven cable of the transportation device is moved between a first station and a second station, comprising:
- arranging at least one generator, which generates electrical energy while the vehicle is moving, on the vehicle in order to supply power to electrical loads of the vehicle,
- supplying the electrical loads of the vehicle with power outside a station by both an electrical energy store of the vehicle and the generator during a first movement phase, in which the vehicle is accelerated to a limit speed out of the station, or, conversely, is decelerated from a limit speed into the station, and
- in a subsequent second movement phase when the vehicle is moving at a speed that is greater than the limit speed, supplying the electrical loads of the vehicle with electrical energy by the generator.
A transportation device, comprising:
- at least one vehicle, which is coupled to a driven cable of the transportation device, for transporting the vehicle between a first station and a second station,
- at least one generator provided on the vehicle, which generates electrical energy while the vehicle is moving in order to supply power to electrical loads of the vehicle,
- wherein an electrical energy store provided on the vehicle and the electrical energy store together with the generator supplies the electrical loads of the vehicle with electrical energy when the vehicle is accelerated to a limit speed out of a station or, conversely, is decelerated from a limit speed into a station, and
- the generator supplies electrical energy to the electrical loads of the vehicle while said vehicle moves at a speed that is greater than the limit speed.
