Abstract

The invention relates to an LEO (low earth orbit) high-voltage solar cell secondary discharge test device and method, belonging to the field of measurement. The device comprises a vacuum chamber, an Ar plasma source, a camera, a three-dimensional driving mechanism, a vacuum-pumping system, a test bench, an insulating mat, a high-voltage solar cell work simulation system, a solar cell array, a non-contact potentiometer and a potential test system. The method comprises the following steps: vacuumizing the vacuum chamber, starting the Ar plasma source to emit plasma, starting the high-voltage solar cell work simulation system to induce the solar cell array to perform surface static discharge, and monitoring the surface potential charge process of the solar cell array by means of the potential test system and the non-contact potentiometer. Thus, the device and the method can well simulate the LEO plasma environment, can work stably and are applicable to various LEO satellite high-power high-voltage solar cell secondary discharge ground simulation tests.

Description

technical field [0001] The present invention relates to a low-earth orbit high-voltage solar battery secondary discharge test device and method, in particular to a high-voltage solar battery secondary discharge ground simulation test device carried out by using an artificial plasma device in a charged environment in LEO (low earth) orbit space and methods. belongs to the field of measurement. Background technique [0002] With the continuous emergence of satellite new technologies and new demands, the requirements for satellite energy systems are also getting higher and higher, so the satellite solar battery power system will develop towards the trend of high power and high voltage. However, the increase in operating voltage also increases the coupling opportunities between solar cells and the space charged environment, and a new failure mode due to space electrostatic discharge appears. In view of the abnormal events and failures caused by electrostatic discharge problems...
