Problems solved by technology

[0006] However, the cost of this solution is relatively high
In addition, multiple auxiliary operating equipment systems are often present in locomotives and train sets (Triebzug), which further increases the costs

Embodiment Construction

[0026] figure 1 A diesel engine 1 driving a generator 3 is shown in FIG. In this case, the diesel engine 1 is the drive motor by means of which the locomotive is driven, that is to say moved on the rails. The generator 3 generates three-phase alternating current, which is rectified by the rectifier 5 . The rectifier 5 is connected to a direct voltage intermediate circuit 7 . With the help of P-UD+ (intermediate circuit 7 figure 1 shown on the upper side) and P-UD- (of the intermediate circuit 7 figure 1 The lower side shown) represents the potential of the direct voltage intermediate circuit 7 . Potential P-UD—for example, can be connected to vehicle ground at the point indicated by reference number 19 .

[0027] Connected to the intermediate circuit 7 are a traction inverter 9 that supplies power to the four drive motors 17 of the rail vehicle through a three-phase connection, a brake circuit breaker 11 connected to a braking resistor 12, and a three-phase AC line to the...

Abstract

The invention relates to a system (20) for supplying auxiliary drives (18) in a rail vehicle with electrical power, wherein said system (20) is connected via an isolating transformer (14) to a power source, such as a DC voltage intermediate circuit (7), wherein said system (20) is connected without a resistor, which limits the current flow, interposed via a protective switch (25) to an electrical reference potential, in particular to vehicle ground, and wherein said protective switch (25) is designed to open upon passage of a current flow through said closed protective switch (25), which is caused by an additional contact of said system (20) to said reference potential.

Description

technical field [0001] The invention relates to a system for supplying electrical energy to auxiliary operating equipment in rail vehicles. Furthermore, the invention relates to a method for protecting such systems in the event of accidental contact with a reference potential, in particular with the vehicle ground. Background technique [0002] In addition to the devices directly necessary for traction (such as high-voltage units, traction inverters and traction motors), locomotives or other rail vehicles or trainset parts serving the operation of railcars or trainsets also have features that enable running add-ons. These auxiliary devices or auxiliary operating devices likewise require electrical energy and are connected in special cases via auxiliary operating device inverters to the traction intermediate circuit from which the energy required for traction is also obtained. Examples are ventilation equipment for traction motors, cooling equipment for converters, compress...
