Transformer system provided with a decoupling system

摘要

To allow simple performance of a voltage test of a high-voltage system, a transformer system having a transformer housing (1) that receives a voltage converter (4) and having an electrical terminal (6) electrically connected to the voltage converter (4) and extended out of the transformer housing (1) for connecting the transformer system to a high- or medium-voltage system, is improved in that a decoupling system (12, 25) actuatable from outside the transformer housing (1) for temporarily interrupting the electrical connection between the voltage converter (4) and the first terminal (6) is disposed in the transformer housing (1). For performing a direct voltage test, the transformer system of the invention no longer has to be detached from the high-voltage system.
