Mine explosion-proof electrical products in the technical development work

Mine production environment is very harsh, gas and coal dust explosions have occurred, therefore explosion-proof electrical switch design and manufacturing is very important. Author many years engaged in mining explosion-proof electrical products,  Electric transformer  development work on how to improve product safety, avoid safety hazards, and accumulated some experience. The main points discussed below are optional.  electri cenergy meter  groove on the rod-proof products, many manufacturers now shell and front cover has a variety of button, the button bar is often used form of ring, ring effect is that once the explosion occurred inside the enclosure, the pressure acting on the F button end of the rod when the rod ring prevents the button is pushed outside shell, thus avoiding the formation of the button bar missing booster channels.
