System and method for monitoring and analyzing insulation states of high-voltage device

Abstract

The invention relates to the field of device detection and specifically relates to an ultraviolet ray detecting based system and a method for monitoring and analyzing insulation states of a high-voltage device. The system comprises an ultraviolet camera shooting module, a terminal video processing module, a distance measurement module, a wireless network module, an ultraviolet video management analysis module and a light emitting diode (LED) display module. By means of an ultraviolet photon number correction method, ultraviolet detection videos are subjected to digital recognition through the ultraviolet video management analysis module to extract information of ultraviolet photon numbers and the like, and the ultraviolet photon numbers are calibrated onto a standard distance scale according to actually measured distances, so that corona discharge intensity can be comprehensively compared and analyzed, influence brought by field detection conditions is eliminated, insulation states of the device is accurately evaluated, and the system and the method have the advantages of being visual, accurate, safe and fast.
