Abstract

The invention provides a detection system and method for satellite installation testing of a satellite power supply and distribution system. The method comprises the steps that satellite installation to-be-tested equipment is connected with a multiplexing switch matrix unit and a power load module through a universal switching test cable; the impedance measurement module is connected with the multiplexing switch matrix unit; the multiplexing switch matrix unit is connected with the data acquisition module; the power load module, the data acquisition module, the multiplexing switch matrix unit and the impedance measurement module are connected with the lower computer and are controlled by the lower computer. The power supply module supplies power to the power load module, the data acquisition module, the impedance measurement module, the multiplexing switch matrix unit and the lower computer. The method has good effects and positive promotion effects on satellite post simplification, risk reduction, accident reduction, efficiency improvement, convenient implementation, equipment universalization improvement and the like.

Description

technical field [0001] The invention relates to the technical field of spacecraft power supply and distribution system testing, in particular, to a detection system and method for satellite power supply and distribution system installation test. Background technique [0002] The satellite power supply and distribution system is responsible for supplying and distributing electric energy to the payload of the satellite and the sub-systems of the service module during each flight phase of the satellite, generally including the solar simulation array (used instead of the solar array during ground testing), power controller, battery pack, Distributors, power distribution equipment of various systems, etc. Before the satellite installation test, it is generally required to conduct a conduction and insulation test on the satellite installation test cable; during the satellite installation test, the power supply and distribution system test is generally carried out in sections accor...
