| 摘 要： | 针对采用100V高压电池阵的空间站结构体带电现象，提出采用等离子体接触器进行主动电位控制方案，根据此方案建立包含接触器的空间站充放电等效电路模型，研究等离子体接触器对空间站充放电过程的影响及空间站结构因素对接触器钳位效果的影响，从而了解等离子体接触器与空间站悬浮电位的耦合特性。结果表明，无论空间站处于“快速充电”还是“正常充电”情况，等离子体接触器均能有效将空间站悬浮电位钳制在合理范围内。空间站结构因素中，电池阵暴露导体面积对接触器钳位过程影响较大，结构体暴露导体面积和结构体等效电容的影响可忽略。

| Abstract: | To defend the charging phenomenon in a 100V solar array space station, an equivalent circuit model is employed to simulate the process of charging and discharging which is based on the solution of using a plasma contactor. Influences of the plasma contactor on the process of charging and discharging and the clamping effect changes caused by the station structure parameters are discussed to make a better understanding of the coupling characteristics between the plasma contactor and the space station floating potential. It is showed that the structure floating potential of the space station can be kept at a safe degree in the situation of “rapid charging event” and “normal charging event” as long as the plasma contactor is working. Influences of the solar array conductor area of the space station on plasma contactor clamping effect are obvious while those of the structure conductor area and structure equivalent capacity are negligible. |
