SJ-10卫星导线特性箱实验装置研制

Experimental facility for wire insulation combustion in SJ-10

为了研究微重力条件下导线绝缘层着火先期征兆和着火早期烟的析出和烟气流动规律,研制了SJ-10卫星导线特性箱有效载荷实验装置。该装置可实现对导线的恒流过载加热,并采用先进的测试技术,获得导线着火先期征兆和烟气浓度分布。地面验证实验表明,该装置安全可靠,同时能充分利用空间实验能力,保障科学目标的实现。

In order to study pre- ignition characteristics,smoke release and distribution characteristics of wire insulation under microgravity,hardware of the wire insulation was conducted. The facility can achieve the wire insulation preheating by overload. Advanced test technology is adopted to obtain the early signs of ignition and the distribution of smoke concentration in the flue gas. The experimental results valid that the hardware is safe and reliable,and it can make full use of the space experiment ability to ensure the realization of the scientific objectives.
