Study on Fault Detection Robot for Oil-immersed Transformer based on WiFi control

For the problem of hefty workload and bring impurity in the process of artificial transformer internal fault detection, a WiFi control based robot is designed to detect the internal fault of the oil-immersed power transformer. The outline structure of the fault detection robot for transformer is illustrated, and WiFi communication module is used to build the control system of the robot. Electromagnetic transmission is used to analyses transmission mechanism of WiFi electromagnetic signal passing through transformer oil, and a communication test was carried. The movement status of the robot in the liquid is tested in this paper as well. The results indicate that the robot designed is able to move flexibly inside the transformer and communicate to the remote control.
