High voltage transformer with a sensor system, method for monitoring of physical parameters of a high-voltage transformer and a sensor system for monitoring physical characteristic variables

摘要

The present invention relates to a high voltage transformer with a sensor system for monitoring of physical parameters. In particular, the sensor system at least one sensor, which comprises a glass fibre with a sensor head. The sensor head carries a plurality of bragg grating. The sensor system, which is assigned to an evaluation unit via the glass fiber with the at least one sensor head is connected. The present invention is based on the general idea of the invention to provide the sensors of the sensor system by means of spacers to be arranged between successive turns of the high-voltage transformer. Furthermore, with the help of a plurality of bragg gratings in the sensor head be ensured that at least one of the bragg grating the actual physical parameters, such as temperature or pressing force, is determined.
