AI Technical Summary
Existing methods for quality control and testing of conductive rings neglect the impact of the initial stage of insulation degradation, resulting in low monitoring accuracy and failure to effectively warn of the decline in the insulation performance of conductive rings, which affects the power supply safety of spacecraft.
Online monitoring is performed using MEMS electrostatic field sensors. The optimal placement of the sensors is determined by the electric field detection curve. Combined with the conductive ring operation simulation structure, accurate detection of insulation defects in the conductive ring is achieved.
This improves the accuracy of monitoring the insulation performance of conductive rings, reduces unknown risks during spacecraft operation in orbit, and ensures power supply stability.
