Abstract: A floating robot design method for inspecting the inside of transformer is proposed to address the problem, which exists in the indirect fault detection approach or the artificial detection method. The internal structure characteristics of the transformer are elaborated, and the characteristics of the robot should be summarized. By using the sealing technology of underwater robots, a robot with the spherical structure is designed, where the robot motion is achieved by jet propulsion. The robot has the characteristics of zero radius of gyration and flexible movement. The feasibility of wireless signal transmission in special transformer oil medium is analyzed with electromagnetic wave theory, and the detailed scheme of the robot control system is designed. The key sensors on the robot are described, and a complete power management system is designed. The principle prototype of robot is designed; the robot is demonstrated in the test oil pool and two 220 kV transformer. The experiment results show that the developed method can take the place of the artificial detection method to complete the fault detection tasks under the special internal circumstance of the transformer.

Key words: robot, oil-immersed transformer, wireless communications, fault detection, robot seal
