-Core filtering algorithm
In order to eliminate the influence of UAV interference signal on the sensitivity of the sensor to the greatest extent, a high sensitivity ultrasonic PD sensor probe is selected, and a multi filter scheme is used to enhance the sensitivity of the detection equipment to discharge.
-Standard module mount
It adopts Dajiang payload SDK mounting protocol, perfectly integrates sensors with UAV, and supports all series of flight platforms of m200 and m300rtk.
-Close range directional detection
Through the intelligent control of the UAV by efei app, the UAV can be as close to the overhead power distribution line as possible in the safe distance range, which greatly improves the reliability of detection information and operation efficiency.
-Real time security and efficiency
It is not limited by geographical environment. The sound wave collected by partial discharge equipment can be decoded and analyzed by software to detect and confirm whether there is partial discharge in overhead line.
application area
Intelligent inspection
It is an advanced technology to use UAV equipped with PD sensor module system for power line patrol. This technology can not only greatly improve the work efficiency, but also greatly reduce the field work. UAV operation can rapidly expand the scope of operation, and it is not troubled by sludge and snow, reducing the cost of line inspection. Therefore, the UAV PD line inspection mode is undoubtedly a safe, fast, efficient and promising line inspection mode.
