Abstract

The invention relates to the technical field of transformer electromagnetic measurement, in particular to an amorphous alloy magnetostriction measurement method and device. According to the amorphous alloy magnetostriction measurement method provided by the invention, the problem that an existing single magnetostriction measurement result cannot accurately represent actual iron core magnetostriction is solved, and magnetostriction characteristics of an amorphous distribution transformer iron core in different stress states can be simulated; measurement of magnetostriction characteristics in the magnetic conduction direction and the lamination direction can be achieved, and data support is provided for vibration and noise suppression of the amorphous alloy distribution transformer.

Description

technical field [0001] The invention relates to the technical field of transformer electromagnetic measurement, in particular to an amorphous alloy magnetostrictive measurement method and device. Background technique [0002] The magnetostriction of amorphous alloy strip is the main source of vibration and noise of amorphous alloy distribution transformers. It is of great significance to study the magnetostrictive properties of amorphous alloy strips to reduce the vibration and noise of amorphous alloy distribution transformers. Existing research methods are mainly based on measuring the magnetostrictive properties of monolithic amorphous alloys. The existing problem is that there is a large difference between the monolithic and the laminated structure in the actual transformer, and the magnetostrictive properties measured by the monolithic alloy cannot be accurately characterized. Magnetostrictive properties of real transformer cores. Due to the lack of characteristic data...
