Problems solved by technology

The calculation error of the black box model is large, and it is difficult to determine the parameters; while the magnetohydrodynamics occupies a large amount of computing resources, the calculation speed is slow, the calculation efficiency is low, and it is difficult to couple with the motion process of the contactor
[0006] Secondly, most of the current research only focuses on a single physical field or the joint simulation of two physical fields. For the simulation of different fields, remodeling is required, the operation is complicated, the time cost is high, and it is difficult to achieve real multi-physics fields. coupling
However, single physics simulation cannot truly reflect the working conditions of the contactor.

Description

technical field [0001] The invention relates to a contactor contact system loading multi-physical field coupling simulation optimization design system. Background technique [0002] Contactors are a large number of devices in the field of electrical engineering, and play an important role in industrial control and power networks. Compared with power electronic devices such as power switch tubes, contactors play an important role in the stability control of medium and high voltage power grids with relatively flat load changes due to their advantages of high voltage and low cost. At the same time, many power plants also use contactors and fuses in series to replace circuit breakers in occasions with many actions and small loads. [0003] The contactor is composed of electromagnetic system, contact system, linkage mechanism and buffer components. The electromagnetic system is the sensing mechanism of the electromagnetic switch. Its working process is to convert electrical ene...
