Embodiment Construction

[0030] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0031] The invention provides a wire transfer insulation treatment structure for a Hall thruster. Two kinds of high temperature resistant heat shrinkable tubes with different diameters are used to realize the insulation treatment of the wire transfer point, which is suitable for insulation treatment under high temperature conditions; Thrusters or other occasions that require the conversion of single-strand core wires to multi-strand core wires and the working temperature is high.

[0032] The insulation treatment structure at the wire transfer point of the Hall thruster mainly includes two sections of small-diameter high-temperature-resistant heat-shrinkable tube 1, large-diameter high-temperature-resistant heat-shrinkable tube 2, single-strand wire 3, multi-strand wire 4, and wire welding joint 5; among them, The wire welding head 5 is a cube s...

Abstract

A Hall thruster wire transfer insulation treatment structure, related to the field of spacecraft electric propulsion technology; including two sections of small-diameter high-temperature-resistant heat-shrinkable tubes, large-diameter high-temperature-resistant heat-shrinkable tubes, single-strand wires, multi-strand wires, and wires Welding head; the axial end of the single-strand wire extends into the wire welding head; the axial end of the multi-strand wire extends into the wire welding head from the opposite position; the single-strand wire and the multi-strand wire are welded inside the wire welding head; 1 A section of small-diameter high-temperature-resistant heat-shrinkable tube is set at the joint between the single-strand wire and the wire welding head; another small-diameter high-temperature-resistant heat-shrinkable tube is set at the joint between the multi-strand wire and the wire welding head; the large-diameter high-temperature resistant heat-shrinkable tube is set in turn On the outer wall of single-strand wire, small-diameter high-temperature-resistant heat-shrinkable tube, wire welding head, small-diameter high-temperature-resistant heat-shrinkable tube and multi-strand wire; It is suitable for insulation treatment under high temperature conditions.

Description

technical field [0001] The invention relates to the technical field of electric propulsion for spacecraft, in particular to a wire transfer insulation treatment structure for a Hall thruster. Background technique [0002] Hall propulsion technology is the mainstream technical direction of spacecraft electric propulsion at present. The Hall thruster mainly includes hollow cathodes, discharge chambers, magnetic poles, magnetic coils, anode / gas distributors, propellant delivery pipelines and support structures; Seoul propulsion technology can increase the payload of spacecraft, reduce launch costs, and extend service life. It is an effective means to improve the efficiency and competitiveness of commercial satellites in the future. [0003] Hall thruster consists of hollow cathode, discharge chamber, magnetic pole (composed of front and rear magnetic pole plates, inner and outer magnetic cores, inner and outer magnetic screens, etc.), inner magnetic coil, outer magnetic coil, a...
