According to the platform cabin and load cabin repeatable locking separation type spacecraft grounding device and method provided by the invention, a load cabin PCDU switch is connected in parallel with a resistor, and the current state of the repeatable locking separation type spacecraft is subjected to switch setting, so that single-point grounding of the spacecraft is realized, and the spacecraft is ensured to be at a zero level reference. According to the system, grounding of the combination body can be achieved through the switch only by changing the internal grounding modes of the load cabin and the platform cabin, operation is easy, and use is convenient. According to the invention, a load cabin PCDU switch is connected in parallel with a resistor, so that the spacecraft can be grounded in a single point no matter in a locking state or a separation state.
本发明提供了一种平台舱与载荷舱可重复锁紧分离式的航天器接地装置和方法,采用载荷舱PCDU开关与电阻并联的形式,通过对可重复锁紧分离式航天器的当前状态进行开关设置,实现航天器的单点接地,确保航天器处于零电平基准。该系统只需对载荷舱和平台舱内部接地方式进行改变,通过开关即可实现组合体的接地,易于操作、方便使用。本发明利用载荷舱PCDU开关开关与电阻并联的形式,使航天器无论处于锁紧状态还是分离状态都能单点接地。
