【摘要】：全日盲紫外成像探测仪可对架空输电线路产生的电晕进行早期探测,降低电力设备损伤。紫外物镜作为全日盲紫外成像探测仪的核心元器件,其性能指标直接影响探测仪的性能。针对电晕检测系统大多存在光能利用率不足的问题,设计了一种基于分色分光的同轴光学系统,消除了中心视场遮拦,增大了紫外光通道的通光口径,有效提高了电晕探测系统的能量收集能力。设计的紫外物镜全视场全探测范围内点列图均方根小于0.14 mm,满足紫外电晕探测的分辨率需求。相较于国外紫外成像探测仪的光学系统,分色分光同轴光学系统的全日盲紫外成像探测仪对能量的收集能力明显高于国外紫外成像探测仪。
[Abstract]:The all-day blind ultraviolet imaging detector can detect the corona produced by overhead transmission line early and reduce the damage of power equipment. Ultraviolet objective lens is the core component of all-day blind ultraviolet imaging detector. The performance index directly affects the performance of the detector. Aiming at the problem of insufficient utilization of light energy in most corona detection systems, a coaxial optical system based on color separation and light separation is designed, which eliminates the central field of view occlusion. Increases the aperture of the ultraviolet channel, The energy collection ability of the corona detection system is improved effectively. The root mean square (RMS) of the designed UV objective lens is less than 0.14mm in the whole field of view detection range, which satisfies the resolution requirement of the UV corona detection. Compared with the ultraviolet imaging detection abroad, the designed UV objective lens is less than 0.14mm. The optical system of the instrument, The energy collection ability of the all-day blind ultraviolet imaging detector in the coaxial optical system of color separation is obviously higher than that of the foreign ultraviolet imaging detector.
