Abstract

The invention belongs to the technical field of testing of transformers, and provides a deformation motoring device of a power transformer winding. The deformation motoring device of the power transformer winding comprises a data collecting unit, a data processing unit and a display control unit, wherein the data collecting unit collects voltage data and current data of the transformer winding, the data processing unit caries out calculation processing, the state of the winding is displayed on the display control unit to judge whether the winding is deformed, and meanwhile the display control unit can output a control instruction to control the data processing unit. The deformation motoring device of the power transformer winding is simple in structure, capable of rapidly and conveniently detecting the deformation condition of the power transformer winding on line, and capable of providing reliable basis for maintenance of the transformer.

Description

technical field [0001] The invention belongs to the technical field of transformer testing, in particular to a power transformer winding deformation monitoring device. Background technique [0002] The power transformer is an extremely important hub of the power system and undertakes the important task of connecting power grids of different voltage levels. The safe operation of the power transformer is directly related to the safety and reliability of the entire power system. Through the statistical analysis of domestic and foreign transformer faults, the results show that the proportion of transformer accidents caused by winding deformation is relatively high. When a small degree of deformation occurs in the transformer winding, although no damage accident will occur immediately, but when the transformer continues to operate for a period of time and the deformation accumulates to a certain extent, it may cause serious failure hazards. Transformer winding deformation detect...
