摘要： The invention relates to a high voltage transformer (6) having a sensor system (30) for monitoring physical characteristic variables. In particular, said sensor system has at least one sensor (1) that comprises a glass fiber (3) with a sensor head (2). Said sensor head supports a plurality of Bragg gratings (7, 8, 9). An evaluation unit (10) is associated with the sensor system and is connected to the at least one sensor head via said glass fiber. The invention is based on the general inventive concept of arranging the sensors of the sensor system between successive windings (4, 5) of the high voltage transformer using spacers. In addition, the use of a plurality of Bragg gratings in the sensor head ensures that at least one of the Bragg gratings determines the actual physical characteristic variables such as temperature or contact force (A).

The resin-molded body has bobbins for the respective coils and core covering portions formed integrally with each other. An exposed area where no resin covers the bottom of the core is formed in the lower face of the covering portions. A holder to fasten the connector is formed integrally with the upper portion of the covering portion. An assembly including the resin-molded bodies in which the annular core is embedded, and the coils wound around the bobbins are retained in a metal casing. A clearance is formed between the assembly and the casing, and a filler is filled in this clearance. The filler covers the exposed area of the core bottom.

摘要： Method and system for predicting an oil temperature of a transformer for a desired load and/or predicting a load that a transformer can support for a desired time. A machine learning algorithm is developed using historical data of a transformer. After the algorithm is developed, historical data corresponding to the transformer are input into the algorithm to develop a profile of the transformer describing how the temperature of oil within the transformer is expected to change as a function of a desired load. Using the profile, the of temperature of the transformer is predicted for a desired load. In this way, a prediction is made as to whether and/or for how long a transformer may support a desired load before the oil temperature reaches a specified threshold and/or before the transformer fails due to the load.

摘要： The cooling system for a power transformer is activated by sensing and processing the frequency characteristic including the harmonic contents, of the inrush current into the transformer, when the transformer is first energized. The cooling system may include motors operating devices such as oil circulating pumps and fans causing a coolant to flow about the power transformer. The cooling system is deactivated by sensing when the transformer is de-energized and when its temperature is below a predetermined level.
