Abstract:

Subject of study. The possibility of using an optical system, which includes two dichroic filters, in a device for remote diagnostics of the state of high voltage equipment and power lines was investigated. Aim of study. Development of a new optical circuit of the device for diagnostics of high voltage equipment with improved spectral characteristics and obtaining images in the ultraviolet range of the spectrum, which includes a Cassegrain­type mirror lens, dichroic filters and matrix photodetectors. Method. It is based on the use of ray calculation of the investigated and optimized optical system of the device for remote diagnostics of high voltage equipment. Computer modeling and aberration calculations made it possible to determine the design and quality parameters of the optical system. Main results. The design parameters of the developed optical scheme, which includes dichroic filters to separate radiation different spectral ranges into separate optical channels, are given. Spectral transmission coefficients of the proposed calculated dichroic filters and options of matrix photo­receiving devices for each optical range are given. Results of aberration calculation and integral transmittance estimation are presented. Practical significance. The proposed optical scheme using dichroic filters allows increasing spectral transmission and obtaining images in the ultraviolet spectral range, and can be used in a device for diagnostics of high voltage equipment and power lines.
