Definitions
- the present invention relates to a drive system with a device for the regulated and / or modulated deactivation and stopping of a cable car according to the preamble of claim 1.
- the mass of the drive pulley can be increased so much that the self-deceleration again reaches the required values.
- the object of the present invention is therefore to solve the problems posed by the direct drives and to design the braking, for example in the event of a power failure, in such a way that a braking distance with a maximum speed prescribed by the standard is obtained without that additional inertia or inertia masses would have to be provided.
- This task will be in accordance with the invention in a drive system with regulated shutdown and Stopping a cable car with the features of the characterizing part of claim 1 solved.
- the deceleration of the system can be actively influenced by supplying energy to the system itself, so that it is controlled depending on the speed and the stopping time is determined by the motor.
- the control and regulation a distinction is made between the control and regulation whether the system conveys uphill (motorized) or downhill (gener at ori s ch).
- the energy supply mains, generator
- the energy required for the shutdown or shutdown of the system is taken from an independent energy source and the motor stops the system according to a ramp specified by the independent energy source
- this energy source and the corresponding regulation be implemented redundantly or in such a way that, for example, if one of the energy sources does not function, the other energy source comes into effect,
- FIG. 1 shows a circuit diagram of a system according to the invention in a first embodiment
- FIG. 2 shows a circuit diagram of a system according to the invention in a second embodiment provided in a redundant design.
- reference number 1 generally indicates a circuit diagram of a device for a drive system for controlled deactivation and stopping of a cable car.
- the device 1 is connected to a three-phase network 2 via a main switch 3.
- the device 1 comprises a frequency converter 4, which is controlled by a controller.
- the controller 5 is connected via a line 6 to the output of the Fr equen z wandl ers 4 and to the input 7 of the Fr equen z wandl ers. It is also connected via a line 8 to devices which detect the speed, braking, etc. of the drive systems.
- the frequency converter 4 is also current-wise with a frequency converter 10, which is opposite to the frequency converter 4 and is likewise monitored by a controller 11 and how the controller 8 is supplied, and with a motor 12 with the interposition of a switch 13 connected.
- the motor 12 is connected directly to a drive 14 of the drive system.
- the drive 14 is connected via a feedback line 15 to the controller 11.
- a switch 16 is provided between the frequency converter 4 and the frequency converter 10 with the interposition of a capacitor, according to which a branch 18 is provided which is connected to an electrical current source 19.
- a branch 18 is provided which is connected to an electrical current source 19.
- This can expediently be of a conventional type in a chargeable battery or a capacitor.
- a capacitor 20 is provided.
- FIG. 2 parts that coincide with those specified in FIG. 1 are provided with the same reference numerals and are not further described.
- a double 1 s cha 1 t er 22 is introduced after the capacitor 17, which contacts a line 32 which converts with a frequency
- a branch 30 is attached from the line, which is connected to an energy source 31 which, in the manner of that 19 of the first exemplary embodiment, is 1 and therefore is not further explained.
- a switch 29 is always provided after the capacitor 17, which acts independently of the double 1 switch 22 and contacts a line 26 which is connected to a frequency converter 27 with a capacitor 28 connected in between ,
- a branch 40 is attached to the line 26 between the double element 22 and the capacitor 28 and is connected to a second energy source 24, which is of the same type as that 19 of the first exemplary embodiment and therefore will not be explained further.
- the frequency converter 24 is connected to an electric motor 34, of a synchronous or asynchronous type, while the Fr equen converter 27 is connected to the same electric motor 34 via a switch 33.
- the electric motor 34 actuates a drive shown schematically in FIG. 35.
- the frequency converter 24 is influenced by a controller 36, while the frequency converter 27 is influenced by a controller 37 by the way of the controller 8.
- the electrical energy source will be dimensioned in such a way that additional energy is supplied in the event of a power failure in accordance with such a ramp that a maximum delay is not exceeded that is prescribed with a value that is suitable for every different type of system changes, for example 1.25 m / s 2 for constantly moving systems.
