Electromagnetic Compatibility Test Method for Electric Propulsion System

Abstract

The electromagnetic compatibility test method of the electric propulsion system includes: the measurement of the wave transmission rate of the wave-transparent sub-chamber of the electric propulsion system; the measurement of the steady-state and transient electric field radiation of the electric Under transient conditions, the peak signal measurement of the power line; the comparative measurement of the conduction and radiation emission characteristics of the simulated load and the real thruster; the measurement of the influence of the plume on the communication, and the electromagnetic compatibility test data of the electric propulsion system. The method of the present invention does not need to be carried out in a professional electromagnetic compatibility laboratory, and the test is directly carried out in the field or the field where the electric propulsion system works. The error of the test result is small, which can truly reflect the electromagnetic compatibility performance of the propulsion system, and greatly reduces Reduced test costs and improved work efficiency.

Description

technical field [0001] The invention relates to an electromagnetic compatibility test method of an electric propulsion system, which is suitable for completion in a non-professional electromagnetic compatibility laboratory, can obtain relatively real test data, and belongs to the field of satellite propulsion system testing. Background technique [0002] At present, the commonly used satellite propulsion systems generally use chemical propulsion systems and electric propulsion systems. However, my country generally uses chemical propulsion systems, and no satellites use electric propulsion systems as the thrust of satellites. [0003] The electric propulsion system mainly includes: a vacuum tank, a wave-transparent auxiliary cabin, and a thruster. The mutual electromagnetic influence between the electric propulsion system and the electronic equipment of other subsystems of the satellite includes two types of conduction and radiation. Effects of conducted and radiated emiss...

Problems solved by technology

At present, the vacuum system used in our country cannot enter the shielded darkroom for EMC testing, so the EMC testing can only be performed in the external field. Due to the influence of the environment, the test results obtained by using the traditional EMC testing method have large errors and cannot truly reflect the advancement.
