Research on Temperature Field Detection Method of Ultrasonic Array Reconstruction Transformer Based on Inverse Multiquadratic Function

Aiming at the defect that the temperature field reconstruction algorithm based on the least square method has the loss of temperature information near the edge, the algebraic iteration technology has many time-consuming steps, and the optimization algorithm lacks stability, this paper proposes a three-dimensional temperature field reconstruction algorithm of transformer based on inverse multi-quadratic function. The ultrasonic array reconstruction transformer temperature field detection system is designed and developed to realize the three-dimensional visualization of temperature field. When the temperature of a certain part of the transformer is too high, the fault location information can be directly provided to the maintenance personnel, which saves the time of troubleshooting and greatly improves the efficiency of maintenance.
