Abstract
In this paper,the high-voltage and high-power electrical connection methods of more-electric engines are reviewed.Firstly,the technical challenges of electrical connection faced by more-electric engines due to high-power motor components,high-voltage systems,and new control modes are analyzed.Secondly,the key technology analysis is carried out from the aspects of high-current connectors,transmission cables,laminated busbars,partial discharge,and electromagnetic compatibility.The design measures such as contact clearance,creepage distance,interface sealing,contact sealing and interlocking function of joining and separating are proposed for high-voltage and high-current connectors.The electrical transmission capacity of three transmission cables,such as copper power cables,lightweight power cables and superconducting cables,is analyzed.The busbar connection technology with high voltage and high working temperature is studied.The mechanism and solution measures of high-altitude partial discharge are analyzed.A combination of simulation and test solution is proposed for electromagnetic interference.Finally,it is pointed out that multi-dimensional optimization design should be carried out in the design process of more-electric engine to achieve the optimal electrical connection.The work of this paper can provide reference for the current design of lightweight electrical system of more-electric engine.关键词
