Definitions
- the invention relates to an electric locomotive and a method for producing an electric locomotive.
- a locomotive is understood to mean a rail vehicle that can, in particular, move a train with a plurality of carriages in towing or pushing operation.
- the locomotive usually has other facilities that distinguishes it from passenger cars and freight cars, e.g. at least one driver's compartment and other devices enabling operation of the locomotive and / or the train.
- a feature of a locomotive is a machine room in which at least a part of the drive unit or units and the auxiliary operation is arranged. Another part of the drive assemblies (eg a main transformer) and auxiliary gears (eg a compressed air generator) may be underfloor, i. H. be located below the floor of the locomotive.
- a power car for a rail vehicle train.
- "locomotive" in the context of the present application on a traction unit or a power car head for heavy rail vehicles and trains may be limited, especially on long-distance, freight and regional trains, and excludes in this case therefore light rail vehicles such as trams and subways of local traffic.
- the voltage of the power supply network is an AC voltage.
- the AC voltage is first transformed by a transformer, which is referred to here as a main transformer, into a lower voltage.
- a rectifier of the electric drive unit in the engine room of the locomotive converts the transformed AC voltage into DC voltage, which via a DC link in turn is supplied to an inverter.
- the inverter In the inverter, a three-phase AC voltage is generated from the DC voltage, with which in turn one or more drive motors of the locomotive can be operated.
- parts of the main transformer can be used as a choke coil.
- the present invention is based on the idea that locomotives with different drive units uniformly, i. to produce as consistently as possible.
- the supporting vehicle construction, with which the unit and the additional facilities are connected should be designed identically for different drive unit types.
- This idea is implemented in that the drive unit, viewed in a direction transverse to the direction of travel of the locomotive (transverse direction), is arranged in a central region of the machine room. This central arrangement of the drive unit even in electric locomotives, makes it possible to design diesel electric locomotives and electric locomotives largely the same.
- the drive unit is arranged so that in the transverse direction on opposite sides of the drive unit access to the drive unit remains free. In other words, the access to the drive unit in the direction of travel are right and left of the drive unit.
- Diesel-electric units are already in previously known locomotives in the middle of the locomotive, both viewed in the longitudinal direction (direction) as also considered transversely to the longitudinal direction, arranged.
- Drive units for electric locomotives with three-phase motors were previously distributed distributed in the locomotive, with several copies of power converters and several copies of high-voltage stands are usually separated by a central aisle through which a person can pass.
- three-phase motors were transformers also (viewed transversely to the direction of travel) arranged centrally in engine rooms of locomotives (see, for example, AT 106754 from 1927).
- the aisle arrangement was introduced.
- the drive unit on high-voltage parts such. B. one of a pantograph on the roof down leading high-voltage line and / or a high-voltage main switch.
- high voltage is meant in particular a voltage of 400 V AC (AC voltage) or more or 600 V DC (DC voltage) or more.
- Contact wire voltages of railway supply networks are typically 1 to 3 kV (DC) and 15 to 25 kV (AC).
- the high voltage parts are not isolated in places, z. B. to contacts of the main switch or copper bars. Therefore, the voltage corresponding safety distances between high voltage parts must be met at different potential and it is mandatory to ensure a safety distance between the high voltage parts and spaces in which body parts of persons can pass, so that a personal accident by electric shock is excluded.
- Usual is a Berstoffschutz, z. B. in the form of a cover plate or blind, which is attached to the drive unit.
- safety distances from the high-voltage parts to the contact protection of several tens of centimeters must be observed. Since the contact protection is at a low electrical potential (it should be grounded), the safety distance must also be maintained because otherwise sparking is possible.
- the safety distance means that all high-voltage parts must either be arranged deep in the drive unit (which must be kept around the high-voltage parts a safety margin, which is not available for other parts of the drive unit available) and / or the width of the adjacent access between the drive unit and outer wall of the engine room is correspondingly smaller.
- the locomotive has a safety system that allows the barrier to open only when the high voltage parts are disconnected from high voltage and grounded.
- the barrier may be any type of obstacle that effectively prevents access and electric shock.
- the barrier does not have to be completely sealed, it may also be e.g. be formed of a close-meshed grid.
- the "opening of the barrier” is understood to mean unlocking and / or at least partial removal of the barrier and / or (more generally stated) removal of the blocking and / or protective effect of the barrier "Opening the barrier” merely creates or enlarges a gap in the barrier so that it can be grasped with one hand.
- the drive unit has in particular a current transformer or parts of a current transformer.
- Other parts of the current transformer can, for. B. underfloor, i. be arranged below the floor of the engine room.
- a current transformer is understood to mean a device which converts electrical currents in any desired manner. The conversion may be a change in the voltage level, frequency and / or type (AC or DC) of the current.
- a current transformer which is connected between the mains connection and the power line to at least one traction motor has, for example, the main transformer, the rectifier at the input of the intermediate circuit and the inverter at the output of the intermediate circuit (for operation on an AC voltage network) and / or a choke coil. Arrangement for smoothing DC voltage fluctuations and the inverter at the output of the DC link (for operation on a DC voltage network).
- a power converter does not have the main transformer but, for example, only the rectifier and the inverter (for operation on an AC mains) or just the inverter (for operation on a DC mains).
- An inverter can also be called a converter.
- the drive unit in the engine room also has a high-voltage stand.
- a high-voltage frame is understood to mean a device in which electrical components and electrical lines for the high-voltage part of the power supply are arranged.
- the high-voltage part has, in particular, the electrical connection between the current collector and the main transformer and a high-voltage main switch.
- the high voltage part in particular has the electrical connection between the current collector and the choke coil arrangement and a high-voltage main switch on.
- at least the high-voltage main switch is arranged in the high-voltage frame.
- the high-voltage main switch can also be arranged elsewhere, for. B. on the roof of the locomotive. In this case, in the drive unit z. B. only be arranged a high voltage line.
- the current transformer or power converter can in any case have other facilities such as frequency filter devices, other switches, fuses.
- the prime mover is designed as a unitary (i.e., single site) unit which can be placed in the same location as in diesel-electric locomotives, the motor-generator combination.
- several power converters for supplying the drive motors are not arranged at different locations in the machine room.
- a related unit is meant an assembly which may be composed of various individual parts and devices, but in the finished, assembled condition, substantially no spaces remain within the unit separating portions of the unit. In particular, there is no gear between parts of the unit.
- Essential distances are distances or gaps that are essential for the space utilization within the locomotive.
- spatial areas of the drive unit may be empty, which in other embodiments (for example for operation on alternating voltage instead of DC voltage) are provided with means.
- all spatial areas of the drive unit are provided with the corresponding facilities.
- the associated unit may also be referred to as an undivided block in the sense that there is no substantial spatial separation, and therefore the unit in the assembled state forms a continuous block.
- all parts of the unit are immediate (not just about the supporting vehicle structure) with other parts of the unit connected. This does not exclude that (as in a preferred embodiment of the manufacturing process) parts of the unit are prefabricated as separate blocks and are joined together during final assembly.
- the main transformer or for operation on a DC network the reactor arrangement is arranged underfloor and the remaining part of the current transformer is arranged as a drive unit in the engine room or . becomes.
- One of the two accesses to the side of the drive unit may be a passage that can be entered from opposite in the direction of travel ends of the access.
- the access without (complete) contact protection can be a corridor that can only be entered at the open barrier. This ensures a very good accessibility to all facilities in the engine room.
- the invention also relates to a manufacturing method for producing a locomotive, wherein in a machine room of the locomotive, a drive unit for providing electrical energy for at least one drive motor is arranged, wherein the drive unit, viewed in a direction transverse to the direction of travel of the locomotive (transverse direction) is arranged in a central region of the machine room, so that in the transverse direction on opposite sides of the drive unit (in outdoor areas) access to the drive unit remains free, in the drive unit high voltage parts are arranged and / or are, wherein between the high voltage parts and access to at least one of the sides no additional protection against contact or no complete contact protection is arranged at the access is arranged without protection against touching a barrier against entering the access, in the locomotive a safety system is arranged, which allows opening of the barrier only if the high voltage parts of high voltage potential disconnected are and are grounded.
