Abstract

Abstract:

Pillar insulators are the components of electrical equipment such as isolating switches and circuit breakers. The safe and stable operation of power system is closely related to the safe operation of insulators. In this thesis, the design and research of substation pillar insulator cleaning system are carried out. The insulator cleaning system is composed of three parts: the air pressure system, the moving system and the cleaning system. Matlab is used to simulate the motion trajectory of the manipulator and the inverse solution of the actual working trajectory meets the requirements. Then, according to the design index requirements of the insulator cleaning system, the circular mounting base connecting the trolley and the mechanical arm is modeled and simulated under ANSYS and Hypermesh, and the stress on the circular mounting base could reach relevant technical indexes. The industrial manipulator programming and simulation tool is used to write the manipulator specific action of the program, achieve coordinate point acquisition, machine instruction programming, program file upload and download. A variety of processing procedures are uploaded to the control server to achieve the command arm programming. This operation mode breaks through the disadvantages of the conventional debugging method, and can be found in time in the virtual 3D animation without loss. Finally, through the waveform test, it can be concluded that the server will estimate the load size and adjust the torque to match the load. The server adjusts the torque by changing the current size in real time.

Key words: Insulator cleaning system, trajectory of motion, stress analysis, waveform test
