Detection device for ultraviolet partial discharge photon number based on laser ranging compensation

Abstract

The invention relates to a detection device for the ultraviolet partial discharge photon number based on laser ranging compensation. An ultraviolet imager and a laser ranging module are installed on a holder. The holder receives an upper instruction signal through a CPU and a wireless communication module and then outputs a control signal to horizontal direction and vertical direction stepping motors to control the holder so that the discharge part is enabled to be in the range of the laser ranging module and the ultraviolet imager and the measured position acts as the standard equivalent observation distance to be stored in a standard parameter storage module. The standard parameter storage module, a control system and the laser ranging module are connected with the CPU and the distance value from the discharge part to the ultraviolet imager is measured according to the laser ranging module. The photon number detected by the ultraviolet imager is equivalent to the uniform observation distance so that the photon number detected under different distance is enabled to have comparability. According to the device, the accuracy of photon number detection of the ultraviolet imager can be effectively enhanced and the device has the advantages of simple structure and high cost performance so that the device has high practical performance and development prospect.
