TECHNICAL FIELD

[0002] In the power system, the lightning rod is an important device for protecting the substation from direct lightning strikes, especially for the substation of 220kV and above voltage level. The round steel lightning rod is a common protective measure. The round steel lightning rod is widely used due to its simple structure and low cost. However, due to the high distance from the ground, small pipe diameter and long length of the round steel lightning rod, it brings great difficulty to the maintenance and repair of the staff.
[0003] The current auxiliary method is mainly to use an insulated boom truck to lift the staff to a high altitude for operation, but this method has high cost and is limited by the space structure of the substation. In most cases, it is difficult to implement and has a high operation safety risk. In addition, the feasibility and safety of the manual detection method under extreme weather conditions are also limited.
[0004] In order to solve these problems, researchers at home and abroad have begun to explore the use of robot technology for lightning rod detection and maintenance.
