Guide wire adaptation insulating treatment structure for Hall thruster

Abstract

The invention discloses a guide wire adaptation insulating treatment structure for a Hall thruster, and relates to the field of spacecraft power propulsion technologies. The guide wire adaptation insulating treatment structure comprises two small-diameter high-temperature-resistance heat shrink tubes, a large-diameter high-temperature-resistance heat shrink tube, a single-strand thread, a multi-strand thread and a guide wire welding head; the axial end of the single-strand thread stretches into the guide wire welding head; the axial end of the multi-strand thread stretches into the guide wirewelding head from the relative position; the single-strand thread and the multi-strand thread are welded in the guide wire welding head; one small-diameter high-temperature-resistance heat shrink tubeis arranged at the joint of the single-strand thread and the guide wire welding head; the other small-diameter high-temperature-resistance heat shrink tube is arranged at the joint of the multi-strand thread and the guide wire welding head; the large-diameter high-temperature-resistance heat shrink tube sleeves the outer walls of the single-strand thread, the small-diameter high-temperature-resistance heat shrink tube, the guide wire welding head, the small-diameter high-temperature-resistance heat shrink tube and the multi-strand thread in sequence. According to the guide wire adaptation insulating treatment structure, the two high-temperature-resistance heat shrink tubes with different diameters are adopted for achieving insulating treatment on a guide wire adaptation portion, and the guide wire adaptation insulating treatment structure is suitable for insulating treatment under a high temperature condition.

Description
