Multiphysics Simulation and Motion Calculation of Transformer Internal Inspection Robot Based on ANSYS and COMSOL
Aiming at a transformer internal inspection robot that needs to complete foreign object detection and cleaning tasks in an environment that is closed,filled with transformer oil medium,narrow space,and without lighting,the flow field,thermal field and other multi-physics fields under the submersible oil movement were simulated and analyzed,and the propeller thrust was simulated and calcu-lated,and the bubble volume generated when the propeller rotates was calculated by the finite element method.Finally,the overall force of the robot when it moved in the oil was calculated.The simulation results show that the transformer internal inspection robot can still operate normally under certain stress and collision conditions;at the same time,the thruster propeller can provide enough thrust to make the robot body move normally,and the bubbles generated during the rotation will not affect normal work of the robot.
