高空下棒-板间隙直流放电特性及电压校正
|
摘要
为研究高空条件下的棒-板空气间隙放电特性,利用低气压放电试验平台对100~600 mm棒-板空气间隙在直流电压下的放电电压U_(50)与气压P、间隙距离d的关系进行试验研究,分析2~30 k Pa气压范围内P与d对U_(50)的影响,得到U_(50)与P、d之间的关系曲线及12 k Pa下600 mm间隙的放电通道发展过程,并提出2~30 k Pa气压范围内的放电电压校正公式。该研究结果可为高空低气压下飞行器的放电特性研究及更系统地开展低气压下长间隙特性试验提供参考。
For the purpose of obtaining rod-plane air gap discharge performance under high altitude and low pressure conditions, Laboratory investigations of the relationship between 50% DC discharge voltage U50, air pressure P and air gap distance d were carried out in the low pressure test platform for 100~600 mm rod-plane gaps. The effects of P and d on U50 were analyzed in the range of 2 to 30 k Pa. The relationship between U50, P and d, and the discharge channel development process of 600 mm long air gap at 12 k Pa were obtained, furthermore, put forward voltage correction formulas of DC discharge within 2~30 k Pa. The results can provide reference for the study of the discharge characteristics of aircraft at high altitude and low pressure conditions, and the systemic discharge tests for rod-plane air gaps.
