Problems solved by technology

[0004] The design of current space equipment usually only considers the highest voltage that may be reached in the natural environment. If the space equipment is affected by electromagnetic pulse radiation, it is easy to stimulate electrostatic discharge and cause a significant drop in the discharge threshold.

Abstract

The disclosure discloses an electrostatic discharge device for space equipment based on electromagnetic pulse excitation, including: a vacuum chamber, an air pumping module, a charging module, a potential monitoring module, a transmission module, a quartz dielectric cavity and an electromagnetic excitation module. The disclosure also discloses a method for electrostatic discharge of space equipment based on electromagnetic pulse excitation. The disclosure can effectively realize the electrostatic discharge of the sample after the electromagnetic wave induced charging by combining the quartz dielectric cavity with the vacuum chamber, so as to study the electromagnetic wave parameters required for the induced discharge.

Description

technical field [0001] The disclosure belongs to the technical field of electrostatic discharge, and in particular relates to an electromagnetic pulse excitation-based electrostatic discharge method and device for space equipment. Background technique [0002] The electrostatic discharge caused by the charging effect of space equipment is one of the main reasons for the failure of spacecraft missions. Despite a relatively adequate protection design, abnormalities caused by spacecraft discharges caused by electromagnetic environmental factors such as geomagnetic substorms and space plasmas still occur frequently, and the specific causes and locations of discharges are difficult to clarify. The charging and discharging effect of spacecraft is the basis and necessary condition for electrostatic discharge, which directly restricts the research progress of electrostatic discharge. [0003] Spacecraft charging refers to the process in which a spacecraft or related components accu...
