Design of Insulation Resistance Measurement System for Electrical Steel Sheet Surface Coating

Abstract:

The surface coating of insulation resistance is one of the key technical indexes of electrical steel sheet, and one of the important parameters of the products of electrical steel sheet. Nowadays the surface coating of insulation resistance device is relatively heavy, measurement error is relatively large, and measurement repeatability is not good. To solve these problems, we design an insulation resistance measurement system based on Infineon XE166 microcontroller. This article analyzes the measuring principle of silicon steel coating surface insulation resistance and includes the three aspects of mechanical, circuit and software. The experimental results validate the feasibility of this system. The measurement system is stable and reliable, high repetition rate, and has a good application prospect.
