Electrostatic protection
static electricity in the production process can cause a variety of hazards. 1n extrusion, cutting, mixing, splashing, fluid flow, induction, friction and other operations, dangerous static electricity will be generated. Due to the high electrostatic voltage and electrostatic sparks, it is particularly easy to cause fire and explosion in flammable and explosive places
electrostatic protection generally adopts electrostatic grounding, increasing air humidity, adding antistatic agent into materials, using electrostatic neutralizer and materials with good conductivity, reducing friction, flow rate, inert gas protection and other methods to eliminate or reduce electrostatic generation
lightning protection
lightning protection generally uses lightning rod, arrester, lightning net, lightning wire and other devices to direct lightning to the earth
lightning rod is mainly used to protect outdoor power transformation and distribution equipment, buildings and structures; Lightning conductor is mainly used to protect power lines; Lightning net and lightning strip are mainly used to protect buildings; Arrester is mainly used to protect power equipment
electromagnetic hazard protection
electromagnetic shielding device is generally used for electromagnetic hazard protection. High frequency electromagnetic shielding devices can be made of copper, aluminum or steel. Metal or metal mesh can effectively eliminate the energy of electromagnetic field, so it can be protected by shielding room and shielding clothing. The shielding device should have a good grounding device to improve the shielding effect
