Abstract

The invention discloses an insulation structure of a gas supply pipeline of a Hall thruster, and belongs to the technical field of Hall thrusters. The problems that under the condition that the spaceis limited, in an existing Hall thruster, connection between a gas supply pipeline and a storage and supply system is limited, and insulation is prone to failing are solved. The insulation structure comprises a gas distributor pipeline, an insulator shell, insulator ceramic and a storage and supply system pipeline. The insulator shell is of an L-shaped structure, and an L-shaped inner cavity is formed in the insulator shell. One end of the gas distributor pipeline is fixedly connected with one end of the insulator shell and communicates with an inner cavity of the insulator shell. A center through hole is formed in the insulator ceramic. The storage and supply system pipeline and the other end of the insulator shell are fixedly connected and communicated through the insulator ceramic.

Description

technical field [0001] The invention relates to an insulating structure of an air supply pipeline of a Hall thruster, belonging to the technical field of the Hall thruster. Background technique [0002] Compared with other propulsion devices, the Hall thruster has the advantages of simple structure, greater thrust, higher efficiency and reliability. After decades of theoretical research and practical application, the engineering research and design of the Hall thruster abroad have been very mature . At present, our country is in the stage of vigorously developing electric propulsion technology, and the research work on the engineering application of the Hall thruster is still in its infancy. Among them, it is extremely important to ensure the safety of the electrical insulation of the Hall thruster and ensure its high reliability. step. Different from the insulation research and design of Changgui electrical equipment working in the atmospheric environment, the Hall thrust...
