Xenon flows into a satellite gas supply bottle through thermal pressurizing devices in the system; the thermal pressurizing type xenon filling system comprises a xenon storage tank, an electronic balance for weighing the storage tank, a gas source valve, a thermal pressurizing device A, a thermal pressurizing device B, a liquefied nitrogen valve A, a liquefied nitrogen valve B, a liquefied nitrogen valve C, a liquefied nitrogen tank, a helium bottle, a helium valve, a control and data collection module, a purity analyzer, a filling valve, the satellite gas supply bottle, a vacuum valve, a vacuum pump, a recycling valve, a recycling module, a gas discharge valve and a satellite gas supply bottle weighing device. According to the technical requirement of high-purity xenon filing in the electric satellite propelling system, a model experiment system is reasonably designed and established. The experiment system has the advantage of high cleanliness degree, accurate temperature control, high reliability, convenience in module replacement and comprehensive date measurement; the feasibility and the reasonability of thermal pressurizing type xenon filling can be effectively tested.
Description
technical field [0001] The invention relates to a hot-pressurized xenon filling system for a satellite electric propulsion system, which belongs to the technical field of high-purity xenon filling tests for satellite electric propulsion systems, and is suitable for filling tests of all electric propulsion systems using high-purity xenon as a working medium. Background technique [0002] At present, there are many types of propulsion systems for in-orbit flight, among which the electric propulsion system has developed rapidly in recent years due to its high specific impulse, especially the Hall electric propulsion system and the ion electric propulsion system are popular, and are often used in geostationary orbit satellites The platform performs tasks such as north-south position keeping, attitude control (momentum wheel unloading), orbit control, and even synchronous orbit transfer. In addition, electric propulsion systems can accomplish tasks that conventional propulsion sy...
