Abstract

The invention provides a method for testing transmission path performance of a solar array driving mechanism. The method comprises the following steps: step 1, a test state is established firstly: power supply of a ground-based simulation array is shunted by a ground transfer cable bundle into two parts; step 2, conductivity and insulativity of a transmission path of the solar array driving mechanism are tested; step 3, then, open circuit voltage of the transmission path of the solar array driving mechanism is tested; step 4, finally, transmission heat consumption of the transmission path of the solar array driving mechanism is tested, a cable connection state in step 1 is restored, and during a surface heat test, all transmission slip rings and star cables of the solar array driving mechanism transmit rated current, and heat consumption of the transmission path of the solar array driving mechanism is simulated accurately. The transmission path performance of the solar array driving mechanism of a satellite is tested on the ground, test coverage of a power supply channel of the satellite of a product is finished, and product reliability is improved.

Description

technical field [0001] The invention relates to a test method, in particular to a test method for the transmission channel performance of a solar array drive mechanism. Background technique [0002] Satellite energy has the following methods: during the ground electrical test, the ground solar simulation array sends energy to the power controller through the cable bundle; Power controller; the ground electrical test simulates the shadow area or the orbit shadow area, and the battery pack supplies power for the whole star. During the ground test, the transmission channel of the solar array drive mechanism did not pass the normal working current test under normal conditions. Even during the ground lighting test, because the intensity of the lighting array is much smaller than that of sunlight, the transmission current is much smaller than the normal working state. [0003] In order to obtain the accurate temperature distribution of the product during the thermal test of the ...
