The robot will collect information such as temperature, oil chromatogram, SF6 gas density, switching characteristics, the leakage current of the arrester and high-pressure chamber environment. Once the temperature exceeds the limit value, it will immediately issue a warning signal to the maintenance personnel, who will take appropriate measures accordingly.

The application of the robot in substation maintenance has realized the unmanned monitoring and inspection of substation equipment at any time, which saves manpower and improves the efficiency of examination.
