Explosion-proof body static ball, body static elimination device, intrinsically safe elimination of the human body in addition to static electricity: 15979264589. Equipment maintenance? 1, to keep equipment clean, regular cleaning of dust and grease touch on the ball to prevent the influence of the human body electrostatic discharge device in addition to static effect. 2, regular inspection and maintenance of equipment, check the grounding wire grounding bolts and other parts are loose, so as not to cause adverse ground. When static electricity and electrostatic hazards to human in space with an electrostatic particle (including friction charged) activity, if the body and the earth insulation, especially wearing a 109 ohm resistor values ??greater than rubber-soled shoes, the body can become isolated charged body. When a certain part of the body with static electricity can cause both the body charged achieve static balance, the body's resistance value is generally 400 to 500 ohms, is a good conductor of static electricity, and the conductor is equipotential. And with the increasing activity of the human body electrostatic potential is also increased. When the body is more than 3 kV discharge electrostatic potential, significant pain; when more than 5 kV discharge, palm and forearm feel a shock, pain, and occur from fingertip site electrostatic discharge spark. So to timely release body static out, or will cause a variety of hazards. In electronic components manufacturing plants: high body static electricity caused by the breakdown of electronic components product obsolescence. In printing: body static sheets bonded together makes it difficult to separate, to printing trouble. In laboratories: the electrostatic attraction of dust inside the human body, with the body into the shop, so that the purity of the drug up to standard; on the operating table: body static electric spark could cause an explosion of anesthetics, injury doctors and patients; in explosive situations : Human static spark will ignite the gas, can cause deaths and injuries of workers, mine scrapped, fire and other important plant disaster. The human body electrostatic discharge static electricity is released, a very good method to eliminate the human body electrostatic hazards. Structure and characteristics of the release: touch the top spherical body, rod end and touch the body and the other end has a fixed flange, fixed flange bolts through fixed on the ground. Touch the body with metal wire leads through the terminal connected to the strut flange, terminal and ground network again, the connection with the earth (such as no ground network can be connected with the earth by way of playing to solder) . ?
