Embodiment approach
[0056] As an implementation, the verification test method based on the verification test device of the spacecraft structure potential active control device may also include:
[0057] S70: Turn on the low-energy electron gun 2 again, and monitor the potential change of the aluminum plate 12 through the potential monitoring module within a predetermined time.
[0058] Through this step, the point-holding ability of the measured spacecraft structure potential active control device can be verified.
[0059] As an implementation manner, before step S10, the verification test method may also include:
[0060] closing the second switch 10;
[0061] Open the vacuum gauge 13 and the vacuum mechanical pump 6, so that the vacuum chamber air pressure drops below 1Pa;
[0062] Turn on the vacuum molecular pump 5 so that the vacuum chamber 1 pressure drops to 1×10 -4 Pa.
[0063] In this way, the vacuum state in the vacuum chamber 1 can be guaranteed before starting the verification tes...
