热真空条件下工作的电气电缆载流量计算与试验

Calculation and test of electrical cable current carrying quantity under thermal vacuum environment

高空制导飞行器从母舱释放后,制导舱与仪器舱之间部分电气电缆处于热真空条件下工作。对此种特定条件下的电缆进行了载流量计算。理论计算表明,给定的电缆设计满足在热真空条件下正常工作要求。最后简略介绍了载流量试验。

After the high altitude interceptor released from post-booster vechicle, part of its electrical cable from guidance bay to equipment bay worked in thermal vacuum environment. Cable current carrying quantity was calculated under this special condition. The results showed that the given cable design could work normally under thermal vacuum environment. At last, current carrying quantity test was introduced.
