Embodiment Construction

[0036] Such as figure 1 As shown, the electric propulsion system is mainly composed of a vacuum tank 1, a wave-transparent auxiliary cabin 2, an electric field receiving antenna 5 in each frequency band, a power processing unit, and an electric thruster 6. The electric thruster 6 is installed in the wave-transparent auxiliary cabin 2, and the electric thruster Power is supplied by the power processing unit, the electric thruster is fixed in the wave-transparent sub-chamber through a flange, and the vacuum tank and the wave-transparent sub-chamber are connected through a flange. In order to enable the electric propulsion system to work normally, it is first necessary to evacuate to make the vacuum tank 1 reach a certain degree of vacuum. After the switching action, the electric propulsion system is in a stable working state, and the plasma is in a stable ejection state, that is, the electric propulsion system is in a stable working state. The electric propulsion system is inst...

Abstract

An electromagnetic compatibility test method for electric propulsion system comprises the following steps: wave transparent rate of wave transparent subsidiary cabins of electric propulsion system is measured; steady state and transient state electric field radiation of electric propulsion system and steady state power line conducted emission are measured; spike of power line when electric propulsion system is in transient state working condition is measured; conduction of fictitious load and radiation emission characteristic and actual thrustor are compared and measured; influence of plume to communication is measured to obtain electromagnetic compatibility test data of electric propulsion system. The inventive method is not required to be carried out in an electromagnetic compatibility laboratory, and can be tested on out-field or working site of electric propulsion system, the test result has little error and can authentically reflect electromagnetic compatibility of the propulsion system, thus greatly lowering test cost and improving working 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 electronic equipment of other subsystems of the satellite includes two types of conduction and radiation, including the influence of electric propulsi...
