Industrial and mining enterprises have electrical equipment transformation, power system optimization transformation, energy efficiency management transformation, information management transformation, safety monitoring transformation and environmental protection transformation. Replace or upgrade electrical equipment that is aging, damaged or unable to meet production needs, such as transformers, cables, motors, switch cabinets, etc. Optimize the design and transformation of power system, and improve the power supply quality, stability and safety of power system, such as adjusting distribution system and optimizing electricity consumption. By improving the process, energy-saving measures and equipment management, the energy utilization efficiency and the effect of energy saving and emission reduction can be improved, such as adopting new energy-saving equipment and optimizing production process. By introducing information technology and intelligent equipment, the automation, digitalization and intelligence of the production process can be realized, and the production efficiency and quality can be improved, such as MES system and intelligent control system. Reform the safety monitoring system to improve the coverage and monitoring accuracy of safety monitoring, such as strengthening video monitoring and installing alarm equipment. The process flow and equipment are reformed, such as adopting new purification equipment and optimizing production technology, so as to reduce the emission of waste gas, waste water and waste residue and improve the environmental protection level of enterprises.
