摘要
针对处于临近空间的飞行器高压供电系统发生的局部放电故障,采用一种基于荧光光纤的全光纤传感系统进行地面模拟环境下的测试,得到等效气压状态下临近空间的局部放电响应参数。该系统等效地面高度可达20 km以上,可实现真空实验舱内直径为86 cm的空间范围内的局部放电故障检测。实验结果表明,基于荧光光纤的全光纤传感系统对不同压强条件下的局部放电故障具有良好的光电响应特性。
An all-optical fiber sensing system based on fluorescent fiber is proposed to detect partial discharge faults during ground simulation experiment for the high-voltage supply system in the cabin of a near-space vehicle.The partial discharge response parameters in the equivalent vacuum state of near space are obtained,and the equivalent ground height of the proposed system is more than 20 km.A partial discharge fault in the vacuum cabin of the flight vehicle with a diameter of 86 cm can be detected.Experimental results confirm that the proposed all-optical sensing system has suitable optical electron response and sensing characteristics for partial discharge faults at different pressures.
