摘要： A method for managing power consumption of a railway vehicle is provided. The power consumption of the railway vehicle is managed by a central control unit that receives information representing an amount of electrical traction power required for traction or generated by electrodynamic braking based on a traction demand set by the driver of the railway vehicle. The central control unit additionally receives information representing an amount of electrical auxiliary power demanded by auxiliary devices from control units of the respective auxiliary devices. The total available electrical power, which can be provided by the energy supply line for the railway vehicle, is determined. The central control unit prioritizes operation of the auxiliary devices based on the total available electrical power and the electrical traction power required for traction to selectively reduce consumption of electrical energy by all or selected auxiliary devices.

摘要： An arrangement for a vehicle, in particular a rail vehicle, or for a building, has a control system adapted to control a plurality of different devices, a cabinet having a lock that can be locked in order to prevent access to a valuable device within the cabinet, and a control unit of the control system adapted to remotely control unlocking the lock. The control system is adapted to unlock the lock automatically if a predetermined condition is fulfilled or to unlock the lock on demand.

摘要： A process for detecting a derailment of a rail vehicle having two or more rail vehicle parts and one or more articulations through which adjacent rail vehicle parts are rotatably connected with one another includes determining an angle of rotation between adjacent rail vehicle parts, and/or a quantity derived from the angle of rotation. The process further includes comparing the angle of rotation or the derived quantity with at least one reference value or threshold, or with at least one reference value range or threshold range. A test criterion indicating whether or not there is a derailment is defined based on the at least one reference value or threshold, and/or an expected relationship of multiple angles of rotation, and/or an expected relationship of the multiple quantities derived from the angles of rotation, relative to one another. The method further includes determining whether or not the test criterion is met.

摘要： Stand-alone remote sensor arrangement for monitoring parameter activity in a cable including a sensor unit, a power source unit, a connecting cable, and a control unit. The sensor unit includes a shielded housing enclosing a toroid-shaped core fixed around the cable to be monitored. The arrangement operates in a low current consumption mode and a measurement mode, in which measurement mode a Hall sensor element senses a predetermined parameter activity of the cable. The sensor unit includes a sensor activation unit arranged and structured to sense parameters related to magnetic field variations in the core caused by parameter activity of the cable, and to generate a sensor activation signal including parameter values dependent on sensed parameters. The control unit receives the signal and evaluates the parameter values in relation to predetermined mode changing criteria, and changes mode of operation of the arrangement dependent on the result of the evaluation.

摘要： An arrangement for earthing a DC intermediate link connected to a converter on board a track-bound vehicle is configured to be permanently arranged on board the vehicle and comprises two conducting members (23, 24) permanently connected to a pole each of a DC intermediate link and to a first contact member (29, 30) each movably arranged with respect to second contact members (35, 36) permanently connected to a chassis part of the vehicle connected to earth. A handle (34) is connected to the first or second contact members while being electrically insulated with respect thereto to be manually operated for moving the contact members connected thereto between a position of not earthing and a position of earthing the DC intermediate link.

摘要： A power converter, an electric drive system and a method for operating a power converter are disclosed. The power converter has connections for connecting to a direct voltage source and connections for electrical connection to phase lines of the electric drive machine. The power converter is configured to convert a direct voltage from the direct voltage source via a direct voltage intermediate circuit into an alternating voltage in order to drive the drive machine. The power converter includes bridge branches for connecting a high-potential section to a low-potential section. A bridge branch includes two half branches with at least one switching device. A resulting nominal voltage of a half branch is greater than a counter-electromotive peak voltage between two phase lines at the maximum rotational speed of the drive machine. A half branch of a bridge branch includes a series circuit of two or more than two switching devices.

摘要： A rail vehicle has a carbody shell having an end wall and a usable space. The end wall includes a doorway for providing access to the usable space, and at least two footplate catchers for preventing a set of footplates arranged adjacent to the footplate catcher from entering the usable space, such as in an event of a crash.

摘要： A cooling system for a rail vehicle having an internal combustion engine as a generator of electricity is operative to exchange heat between a cooling fluid circulating in a cooling circuit connected to the internal combustion engine and air located in an underfloor space of the rail vehicle. A heat exchanger and a fan, located in the underfloor space, are fluidly connected to an exhaust in a side skirt depending from a floor of the rail vehicle. The fan is operative to force air from the underfloor space through the heat exchanger and through the exhaust to an ambient space located on an external side of the side skirt.
