摘　　要：为了实时监测高压电晕放电,需要一种灵敏、便携、可普遍推广使用的电晕检测设备。通过需求分析,采用日盲区响应波段的紫外火焰探测器感应进入系统的光子数来评价电晕放电强度。为提高探测灵敏度,设计了一套由单片双凸球面透镜、超半球固体浸没透镜和紫外探测器构成的紫外光学系统。该系统结构简单紧凑,有较大的能量汇聚比,提高了系统的探测能力。通过Matlab计算和Lighttools仿真设计,原理样机测试结果验证了该设计完全满足使用需求。In order to real-time monitor the high-voltage corona discharge,an ingenious,portable and inexpensive corona testing equipment is needed and can be widely used in the future.Through requirements analysis,an UV flame detector to count the number of photon and evaluate the corona intensity is used.In order to improve the detection sensitivity,an ultraviolet system was designed which composed of double-convex spherical lens,super-hemispherical solid immersion lens and an UV detector.The system is simple and compact,together with greater energy concentration ratio to improve detection capability.Designed by Matlab calculation and lighttools simulation,the test result of the sample machine shows that the system can fully meet demands.
