Description

technical field [0001] The invention relates to the field of satellite protection, in particular to a detection device for satellite deep-layer charging potential of medium-high orbit satellites. Background technique [0002] Due to the action of high-energy particles, the medium or ungrounded conductor inside the satellite will form a deep charging of the satellite similar to the electrostatic charging on the ground, that is, the charged particles in space accumulate in the internal medium of the satellite, which will cause the internal medium of the satellite. Charge accumulation forms an uneven electric field inside the medium or a large potential difference with the surroundings. When the electric field strength in the concentrated area of ​​the electric field inside the medium exceeds the tolerable strength of the medium or the electric field strength with the surrounding space exceeds the tolerable electric field strength of the space, it will cause discharge between d...
