Research on the automatic measurement of the clearance width of flameproof electrical apparatus

In view of flameproof electrical apparatus gap measurement demand in the current coal mine and other flammable and combustible environment, this paper proposed a new automatic measurement method for mine flameproof clearance measuring, which is fast and easy to operate and satisfy the demand of gap measurement of bulk flameproof equipment under mine. Based on the image processing method, the measuring instrument uses the microscope camera to collect the image, and the gap width is obtained by analyzing and processing the gap in the image. The measurement is fast, real-time and portable, which can significantly improve the efficiency of the current underground safety inspection.
