Design and analysis of oil-immersed transformer internal detection robot

Safety and reliability of transformer and its fault diagnosis ability are key factors to guarantee stable operation of power system. Aiming at traditional oil-immersed transformer detection methods exist low intelligence, high maintenance costs and high working intensity defects, in this paper, underwater robot technology is applied in oil-immersed transformer detection field, and a kind of floating robot is designed. Moreover, the robot motional and hydrodynamic characters are analyzed and some key structures and equipment are designed. Based on calculation of robot hydrodynamic and jet propulsion theory, the design graphs of jet propellers are established, which could guide design and selection of jet propulsion system. The achievement of this paper will add momentum to transformer internal detection unmanned and intelligent.
