1results about How to "Solving Convergence Problems" patented technology

This invention relates to the field of force-electromagnetic coupling measurement, and discloses a method and system for the internal arrangement of a low-voltage power metering box based on a modular transformer plug-in structure. This method deploys multi-source sensors to synchronously collect time-series data on the magnetic flux density of the three-phase modules, the strain field of the base, and the preload. A directed weighted hypergraph is constructed to represent the magnetoelastic coupling topology, which is then converted into a time-varying creep rate matrix using a viscoelastic creep memory operator. Combined with phase space partitioning and a magnetostrictive response tree generation compensation strategy, the final result is an inverse mapping to an optimized scheme for module spacing and interface stiffness. This invention solves the problem of time-varying coupling drift caused by structure-electromagnetic coupling and viscoelastic memory effects in modular transformers by accurately capturing the time-varying mechanical laws of the strain field and preload, overcoming the limitations of traditional static independent calibration, and achieving long-term stability of three-phase metering accuracy.
