An ultraviolet endoscopic system is researched for the partial discharge of high-voltage power equipment,which consists of the ultraviolet endoscopic probe,embedded computer system and GPRS module.The hardware and software composing of the embedded system,as well as the video image collecting process of the USB camera are introduced.The ultraviolet endoscopic software is developed based on Qtopia.The ultraviolet radiation with specific wavelength is examined by the ultraviolet sensor which is blind to sunlight to detect the partial discharge of power equipment.Based on the internal environment study of power equipment,the system combines the ultraviolet discharge detection technology with the video endoscopic technology and realizes the real-time online GPRS-based monitoring of power equipment.Experiments prove that the system runs reliably and effectively.
