文章提出了航天器低频电缆网的设计原则,以某航天器低频电缆网的设计为例,详细介绍了该低频电缆网功能的实现方法;整理归纳了地面测试阶段,航天器低频电缆网对航天器火工品、太阳电池阵驱动机构、蓄电池组等的安全保护措施。经航天器初样阶段验证,该低频电缆网设计合理可行,完全满足航天器任务要求。 This paper presents the design principle of spacecraft low frequency cable network. Taking the design of a spacecraft low frequency cable network as an example, the method of realizing the function of the low frequency cable network is introduced in detail. The ground testing phase, spacecraft low frequency cable network, Fire products, solar array drive mechanism, battery safety protection measures. After the initial phase of the spacecraft validation, the low-frequency cable network design is reasonable and feasible, fully meet the mission requirements of the spacecraft.
