Schaffner components in propulsion systems of locomotives and ships
Schaffner subassemblies – transformers and power inductors – are used in the drive units of locomotives and increasingly in ships with modern combination propulsion (diesel/electric engines) as well as in railway carriages. They ensure efficient use of power and the fault-free flow of energy upstream of the drive system as well as between the drive system and the motor, and they also prevent faults in the electrical functions.
In the combined diesel/electric drives used in modern ships, it is no longer the diesel engine that drives the ship's propeller, but an electric generator. The energy generated there is fed into electric motors which then act as a variable drive for the ship’s propeller. Schaffner products are also used in a typical frequency converter application in this process of converting the drive energy. Furthermore, every ship requires a large amount of energy for its own use. The stability of on-board power networks and the flawless functioning of the electrically powered devices are major application areas for Schaffner components.
Components for use in modern trains and ships must be highly resistant to temperature and vibration and be extremely reliable and robust. Simulation of customer specifications is therefore carried out in the initial stages of product development. Following construction of prototypes, various tests are carried out. This can significantly reduce the time to market of new products for customers, and individual requirements can be taken into account. During product development, Schaffner draws on its broad application knowledge and applies a proven computer-aided measurement and testing procedure. The components developed on this basis are then tailored to the customer's systems and integrated, for example, in modern locomotives and ships.
