Application scenario
Power inspection robot can be used in high temperature, strong electromagnetic interference environment and severe weather such as heavy rain, strong wind and heavy snow. It can be loaded with infrared thermal imager, high-definition camera and other related substation equipment detection devices for automatic inspection and special inspection. The method of inspection, instead of patrolling the high-voltage equipment of the substation, detecting and identifying the internal meter and timely discovering internal thermal defects of the power equipment, external mechanical or electrical problems such as foreign objects, damage, heat, oil leakage, etc. The operator provides data on the diagnosis of accidents and failure precursors in the operation of electrical equipment.
