衛(wèi)星星上功率電纜熱特性研究

Thermal characteristics of power cables of satellite

摘要: 文章根據(jù)某衛(wèi)星在軌工作工況，對星上功率電纜的熱特性進(jìn)行了理論計(jì)算，以此為基礎(chǔ)結(jié)合衛(wèi)星在軌外熱流環(huán)境條件，提出了整星狀態(tài)下的試驗(yàn)驗(yàn)證方案，通過試驗(yàn)驗(yàn)證獲取了星上功率電纜在整星狀態(tài)下的溫度參數(shù)分布，對獲取的溫度數(shù)據(jù)及其環(huán)境特點(diǎn)進(jìn)行了分析，獲得了星上功率電纜的熱特性，對電纜在衛(wèi)星內(nèi)的走向、固定方式等提出建議。研究成果可為后續(xù)衛(wèi)星功率電纜相關(guān)設(shè)計(jì)提供參考。

Abstract: The heat characteristics of the cable are theoretically determined in the working mode of the satellite in orbit, then considering the heat environment of the satellite in orbit，the testing scheme of the power cable of the satellite is established. The temperature distribution in the power cable is obtained through the satellite system testing, then the temperatures and the environmental characteristics of the cable are analyzed. The cable orientation and fixing manners are suggested for the power cables.
