AI Technical Summary

Technical Problem

In the existing technology, when using wind pressure sensors and pitot tubes to measure the wind pressure of insulators, there are large measurement errors, which affect the flow field distribution, leading to inaccurate analysis of insulator defects, and are prone to flashover accidents caused by low air pressure.

Method used

By using a BMP280 barometric pressure sensor combined with flexible insulating material, the wind pressure on the insulator surface is calculated by measuring ambient air pressure, wind speed, and insulator creepage distance parameters. This avoids the influence of traditional equipment on the gas flow field. The sensor is embedded in a U-shaped groove and sealed with putty to ensure measurement accuracy.

Benefits of technology

This improves the accuracy of wind pressure measurement on insulator surfaces, ensures the accuracy of defect analysis, avoids flashover accidents, and enhances the reliability of measurement results.
