一种载人航天器高压供电系统接地方法

A Grounding Architecture for High-voltage Power System of Manned Spacecraft

采用高压供电是载人航天器供配电方案的选择之一。我国已经开展了高压供电的应用。文章介绍了几种接地方法,通过对国际和国内相关接地要求的研究,以及载人航天器接地系统的分析,提出了"柔性接地"的方案和实施方法,此方法可以同时提高航天器和航天员的安全性。

High voltage power supply system is an option of power supply distribution schemes for the manned spacecraft. The high voltage power supply system has been already in use in chinese spacecraft. This paper introduces some grounding methods and makes some researches on the domestic and international grounding criterion in the correlative field and some analysis on manned spacecraft grounding system. Finally it indicates a scheme of ＂flexible grounding＂, and shows how to bring it into effect, which can improve the safety of the spacecraft and astronauts.
