Embodiment Construction

[0030] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0031] The winding is the core part of the transformer and belongs to the conductive circuit. The winding can be made by winding aluminum wire or copper wire on the iron core. The wire is generally insulated with paper. Transformers with different capacities have different structures and different internal windings. In the power system, there are four types of windings widely used: cylindrical, t...

Abstract

The invention is applicable to the technical field of transformer signal analysis, and provides a transformer vibration signal separation method and terminal device. The method comprises the followingsteps of acquiring the vibration signal of the transformer; obtaining the core vibration signal and/or winding vibration signal of transformer by processing the vibration signal of transformer with the preset separation model. According to the transformer vibration signal separation method according to an embodiment of the present invention, the preset separation model is used to classify the vibration signal of transformer, so that the separation of core vibration signal and winding vibration signal is realized. Compared with the traditional blind source separation algorithm, the separationresults of this method are significantly improved in reliability and accuracy.

Description

technical field [0001] The invention belongs to the technical field of transformer signal analysis, and in particular relates to a transformer vibration signal separation method and terminal equipment. Background technique [0002] The power transformer is one of the most important equipment in the power system. If the power transformer fails, it will cause a large-scale power outage and seriously affect the production and life of the people. The iron core and winding on the power transformer are the parts with more failures. At present, the surface signal of the power transformer oil tank measured based on the vibration analysis method contains rich vibration information of components such as iron core and winding. After the vibration signal is generated from the vibration source, due to aliasing and interaction, and through a series of channels such as transformer oil and oil tank firmware, it is transmitted to the surface of the transformer, so that the vibration signal ...
