Mechanical Structure Design and Strength Analysis of 750 kV High Voltage Test Platform

In this paper, a vehicle-mounted test platform with a weight of 6500 kg is designed to meet the requirements of 750 kV high-voltage test. In this paper, a three-dimensional model is designed, and a mechanical model is established to carry out theoretical mechanical analysis of the strength of hydraulic support and base support, and conduct mechanical simulation using finite element analysis software to obtain the maximum deformation value and equivalent stress of the test platform. The simulation results show that it can meet the use requirements. At present, the equipment has been successfully applied to the field test of 750 kV high voltage withstand voltage test.
