AI Technical Summary
Existing partial discharge tests lack a complete test platform, making it impossible to perform multi-source data fusion and analysis, and difficult to accurately identify complex fault types. Furthermore, no solution has been found that combines partial discharge detection with infrared thermal imaging, making it difficult to comprehensively analyze potential faults in power distribution network equipment.
An infrared multimodal partial discharge simulation test platform is designed, which integrates a test circuit, test chamber, infrared temperature measurement and imaging module, multimodal sensor module and data acquisition system. It supports the detection of multimodal electromagnetic signals such as high frequency, ultra-high frequency, ultrasonic, and transient ground wave, and combines infrared overheating defect detection.
It achieves the fusion analysis of multimodal data, which can more accurately predict potential defects in power distribution network equipment, reduce accident risks, and ensure the stability of power supply.
