COMPRESSOR SYSTEM FOR A RAIL VEHICLE AND METHOD FOR OPERATING THE COMPRESSOR SYSTEM WITH SAFE EMERGENCY OPERATION

摘要

A rail vehicle compressor system and method for controlling the same use a compressor driven by an electrical machine via a drive shaft, to produce compressed air for at least one compressed air tank, wherein the electrical machine can be activated at least indirectly via a control device for operating the electrical machine at at least one nominal speed between a maximum speed and a minimum speed, wherein at least one pressure sensor determines the pressure for the control device and is disposed in a compressed-air-carrying line downstream of the compressor. A final control element continuously influences the speed of the electrical machine and can be activated via the control device, and wherein a pressure switch for monitoring the pressure in the at least one compressed air tank and for influencing at least the speed of the electrical machine is disposed in the compressed-air-carrying line downstream of the compressor.

主权项

1. A compressor system for a rail vehicle, the compressor system comprising:
at least on compressed-air vessel; an electric machine; a drive shaft; a compressor which is driven by the electric machine via the drive shaft and which generates compressed air for the at least one compressed-air vessel; a regulation device which at least indirectly controls the electric machine for operation of the electric machine at at least a rated rotational speed between a maximum rotational speed and a minimum rotational speed; a compressed air-conducting line arranged downstream of the compressor and including at least one pressure sensor for determining the pressure for the regulation device; an electric supply; and an actuator arranged between the electrical supply and the electric machine, wherein the actuator continuously manipulates the rotational speed of the electric machine and is controlled by the regulation device; and a pressure switch arranged in the compressed air-conducting line downstream of the compressor for monitoring pressure in the at least one compressed-air vessel and for manipulation of at least the rotational speed of the electric machine.
