Exploration of Electrical Grounding Protection Technology of Chlor-Alkali Chemical Plant
There are flammable and explosive substances in the production process of chlor-alkali chemical industry,and the voltage level of its power supply and distribution system can reach more than 10 kV.Production devices are mostly electrical equipment,in order to prevent the production equipment from generating arcs and sparks,and at the same time,to prevent personnel electrocution accidents,should be designed to systematically protect the technical measures of electrical grounding.The research process to a chlor-alkali production enterprises as the background,the original electrical grounding scheme analysis,found that the TN-S form of grounding system can not effectively prevent the equipment shell and single-phase collision of electrocution hazards,so the original scheme is optimised.Repeated grounding is set for the grounding trunk,and the ungrounded equipment is protected in the form of TT grounding,meanwhile,neutral resistance grounding protection is taken to improve the reliability and safety of the power supply and distribution system.
