Automatic Monitoring of Insulation of Substation High-voltage Electrical Equipment Using Infrared Image Technology
To improve the accuracy of insulation monitoring for substation high-voltage equipment,an automatic insulation monitoring method using infrared image technology was designed.The method was designed to extract charac-teristic quantities such as dielectric loss value and instantaneous power transformation and use them together with image information scanned by infrared thermal imagers to train insulation state related features,and separate and reconstruct harmonic signals,thereby achieving automatic insulation monitoring.The method achieved in experiment a a high monito-ring accuracy as the error of the monitoring result was only 0.1℃.
