Abstract

The invention is applicable to the technical field of transformers, and provides a transformer and a winding thereof, so as to solve the problem that the winding deformation cannot be detected in realtime in the prior art. The transformer winding comprises a winding body and a displacement sensor; A displacement sensor is arranged on the outside of the winding body for detecting deformation of the winding body. A transformer and a winding thereof provided by an embodiment of the present invention, As that displacement sensor is arrange on the outside of the winding body, the deformation of the win can be detected in real time by the displacement sensor, the deformation of the winding of different degrees in the transform can be found in time, the accident of the transformer can be reduced, the service life of the transformer can be prolonged, and the operation reliability of the transformer can be improved.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a transformer and windings thereof. Background technique [0002] In the power system, the transformer is one of the main equipment of the power system, and its operation reliability is directly related to the safe operation of the power grid system. With the increasing capacity of the power grid, transformer damage accidents caused by short-circuit faults are on the rise. According to statistics, among transformer faults with a voltage level of 110kV and above, accidents caused by external short circuits account for about 36.4%. When the transformer is subjected to short-circuit impact during operation, the winding may produce permanent instability deformation such as winding twist, tilt, collapse, bulge and displacement under the action of electrodynamic force. If the above-mentioned deformation is not detected in time, the cumulative effect will further aggravate the de...
