摘要
电缆网绝缘防护对于确保空间飞行器供配电安全具有重要意义。基于空间飞行器电缆网二次绝缘防护现状,以某两型空间飞行器为例对二次绝缘不到位原因进行分析,确定了通过影像记录无法确认二次绝缘实施状态、二次绝缘实施部位不明确和二次绝缘实施确认时机不明确3个要因,并提出相应的防护优化措施,有效提升了空间飞行器电缆安装绝缘防护质量。
The insulation protection of cable harnesses is of significant importance for ensuring the safety of power supply and distribution in spacecraft.Based on the current status of secondary insulation protection in spacecraft cable harnesses,this study analyzes the causes of inadequate secondary insulation implementation using two specific types of spacecraft as examples.Three key contributing factors were identified,namely,inability to verify the implementation status of secondary insulation through image documentation,ambiguity in designated implementation areas for secondary insulation and unclear timing for implementation verification of secondary insulation.Corresponding optimized protection measures are proposed,effectively enhancing the insulation protection quality during spacecraft harnesses installation.
