Abstract

A motive installation with equipment for the regulated and/or modulated disconnection and stopping of a cableway comprising an electric motor (12,34) connected to actuation of the cableway with an electric mains system (2) being connected electrically to the motor is described.

In accordance with the present invention the equipment comprises a first frequency converter (4) arranged between the motor (12,34) and the mains connection (2) with a first regulator (5) being connected to the outlet of the first frequency converter (4) with entry of the frequency converter (4) with a line (8) connected to devices detecting operation of the cableway installation and with at least a second frequency converter (10,24,27) respectively influenced by a regulator (11,36,37) with the outlet of the at least one second frequency converter (10,24,27) being connected to the electric motor (12) with between the first (4) and at least second frequency converter (10,24,27) there being shunted at least one power supply of an electric power source designed to operate for a predetermined time and upstream of such shunt there being inserted a shunt (16,22,29) designed to be controlled in opening upon power failure or by the braking or stopping program of the installation.

Claims

1. Motive installation with equipment for the regulated and/or modulated disconnection and stopping of a cableway comprising an electric motor (12,34) connected to actuation of the cableway with an electric mains system (2) being connected electrically to the motor characterized in that it comprises a first frequency converter (4) arranged between the motor (12,34) and the mains connection (2) with a first regulator (5) being connected to the outlet of the first frequency converter (4) with entry of the frequency converter (4) with a line (8) connected to devices detecting operation of the cableway installation and with at least a second frequency converter (10,24,27) respectively influenced by a regulator (11,36,37) with the output of the at least one second frequency converter (10,24,27) being connected to the electric motor (12) with between the first (4) and at least second frequency converter (10,24,27) there being shunted at least one power supply of an electric power source designed to operate for a predetermined time and upstream of such shunt there being inserted a shunt (16,22,29) designed to be controlled in opening upon power failure or by the braking or stopping program of the installation.

2. Installation in accordance with claim 1 characterized in that the power source is a battery.

3. Installation in accordance with claim 1 characterized in that the power source is a block of capacitors.

4. Installation in accordance with claim 1 characterized in that the electric motor is a synchronous electric motor.

5. Installation in accordance with claim 1 characterized in that the electric motor is an asynchronous electric motor.

6. Installation in accordance with claim 1 characterized in that the shunt power source is sized in such a manner that the power supply therefrom responds to a ramp bearing the cableway running speed below a maximum deceleration for braking.
