Definitions
- the present invention relates to a current collector system for a rail-bound vehicle according to the features in the preamble of claim 1.
- Rail-bound vehicles are usually driven electronically.
- overhead lines are arranged along the rail network, wherein the rail vehicle via a pantograph system receives the energy from the overhead line.
- a pantograph system is on the one hand adjustable in height and in particular resiliently mounted, so that vibrations and / or different heights between overhead line and rail can be compensated while driving.
- pantograph system may be lowered.
- sensor systems are known, for example, from EP 1 366 947 A1 or DE 10 2012 108 492 A1, in which a bus bar or contact strip has an air duct.
- the pressure in the air duct is monitored and if a fault occurs, the air duct on the busbar is damaged. This results in a pressure drop, so that a corresponding fault, also referred to as an accident, is detected and the current collector is lowered via an actuator.
- the compressed air for the pneumatic sensor system is based on the compressed air system of the rail vehicle, which is also used, inter alia, to adjust the pantograph itself in height.
- Object of the present invention is to provide a current collector system, which is equipped with a fail-safe sensor system for the detection of an accident, the sensor system is optionally retrofittable to existing pantograph systems and has a low weight.
- pantograph system for a rail vehicle with the features in claim 1.
- the pantograph system for a rail vehicle wherein the rail vehicle is fed with energy through a catenary, has a pantograph with at least one sanding strip, wherein the sanding bar is adjustably mounted in height via a rocker by means of an actuator, so that the sanding strip with a catenary in Contact is bringable.
- the current collector system further comprises a pneumatic monitoring system which has an air duct arranged in or on the sliding strip and detects damage to the air duct disturbance between the contact strip and the overhead line and initiates a lowering operation of the rocker.
- the current collector system according to the invention thereby characterized in that the monitoring system has its own separate pneumatic system.
- the pneumatic system includes within the scope of the invention, a compressor and a control unit and optionally a storage device. Furthermore, then in the context of the invention to the pneumatic system counting the compressed air lines and the air duct of the monitoring system.
- the pneumatic system can also be referred to as a compressed air system.
- the air duct is integrated into the sanding strip or is arranged on the sanding strip depends in particular on the system requirements or whether the monitoring system according to the invention is retrofitted to an existing current collector system or the current collector system is redesigned.
- the arrangement of the air duct at or in the immediate vicinity of a sanding strip allows easy retrofitting. If the abrasive strips are replaced, it is also possible to use when retrofitting a monitoring system according to the invention also abrasive strips with integrated air duct. The same applies to the redesign of a pantograph system.
- the rail vehicle does not necessarily have its own pneumatic system, from which the monitoring system is then supplied with compressed air. Due to its own compressor, the monitoring system requires only one electrical connection, so that the compressor can fill the pneumatic system, in particular the storage tank, with compressed air, the compressed air then being used to operate the transition system.
- the monitoring system itself then works according to the aforementioned prior art.
- the pneumatic system is autonomously or independently applicable to the pantograph. All that is needed is an electrical connection for operating the compressor and / or the control unit.
- the pneumatic circuit of the monitoring system is self-contained, so that the monitoring system can be arranged directly on a current collector system.
- pantograph systems In addition to the significant advantage of retrofitting on existing pantograph systems without a pneumatic monitoring system continue to arise in newly designed pantograph systems two advantages.
- the entire current collector system has to be electrically coupled to the vehicle only, not again via separate pneumatic connection lines, since the monitoring system associated with the current collector system can be mounted directly on the current collector system with the separate pneumatic system.
- the initial assembly costs but also the installation costs for maintenance in a current collector system equipped according to the invention, are reduced.
- pantograph system Another benefit that results is the low overall weight of the pantograph system. It can thus be a known current collector system, which is set up by means of a mechanical spring and by means of an electric and / or electromechanical, in particular electric spindle drive opposite the spring force is lowered, provided with a proven pneumatic monitoring device, without significantly increasing the total weight.
- the pneumatic system is assigned directly to the pantograph.
- the pneumatic system further comprises a control unit, which is in particular an electropneumatic control unit and is connected to the actuator. Now detects the control unit a pressure loss due to damage to the air duct in the busbar, the control unit is a control signal to the actuator for lowering the rocker.
- a pressure switch is provided in particular in the control unit, which detects the pressure drop due to the damage of the air duct and converts it into an electrical signal.
- the actuator itself is operated pneumatically or hydraulically.
- the monitoring system according to the invention with its own separate pneumatic system can also be retrofitted to such a pantograph with pneumatic or hydraulic actuator.
- the air duct is brought into connection with the pneumatic system of the pantograph system.
- the air duct uses its own separate pneumatic system.
- the monitoring system acts self-sufficient of the existing actuator, wherein only the control unit of the monitoring system in the case of detecting a pressure drop sends a control signal to initiate the lowering process to the actuator.
- the current collector system according to the invention further has a Schnellabsenkfunktion, so that the sliding strip of the pantograph is lowered in particular in less than three seconds, preferably less than two seconds and in particular less than or equal to 1 second from an operating position.
- the quick lowering process requires at least a few milliseconds.
- the rapid lowering function can mean the complete lowering of the current collector, however, at least the rapid lowering function is carried out within the predetermined time in such a way that a minimum insulation distance from the contact strip to the contact wire or the overhead line is established.
- the spindle drive In the case of using an electric or electromechanical drive and in particular a spindle drive, it would be possible to realize by applying the spindle drive with a higher voltage and / or with a higher current compared to the regular raising or lowering the Schnellabsenkfunktion.
- the Schnellabsenksystem can be formed by an additional pneumatic Schnellabsenkzylinder. This can be arranged parallel to the actual actuator and in particular to the spindle drive or arranged in series with the spindle drive.
- the pneumatic quick-lowering cylinder offers the advantage, in particular over an electromechanical spindle drive, that it can travel a greater distance within a shorter time, so that the rapid lowering function is realized.
- the pneumatic quick-lowering cylinder can then be fed in particular by the pneumatic system of the monitoring system with compressed air.
- a storage memory which is preferably designed as a pressure vessel
- a stored pressure can be provided in a very short time, which causes the actuator movement of the pneumatic quick-lowering cylinder.

- the device according to the invention of the separate pneumatic system 9 is shown enlarged in FIG. 3 and again in detail in accordance with FIG.
- the pneumatic system 9 has for this purpose a compressor 10 in the form of a compressor and a control unit 1 1 for monitoring an air duct L shown schematically in Figure 3 in the grinding strips 4. Also both grinding strips 4 each have an air channel L. Furthermore, a storage 12 is provided so that the pneumatic system 9 and the entire pneumatic circuit is supplied with compressed air. Furthermore, the own separate pneumatic circuit then has not yet shown compressed air lines, which connect the air ducts arranged in the grinding strips 4 with the pneumatic system 9.
- the pneumatic system 9 can then be coupled via an electrical connector 13 to the rail vehicle, not shown, so that the pneumatic system 9, in particular the compressor 10 of the pneumatic system 9 and the control unit 1 1, are supplied to their operation with power.
- the monitoring itself then takes place purely pneumatically.
