The company occupies 150000 square meters of thick plate muffler on the ground, with a workshop area of 60000 square meters. It has floor boring machine, CNC vertical lathe, CNC horizontal heavy lathe, CNC gantry milling machine, sheet metal processing center, laser cutting machine heat dissipation muffler, numerical control plate cutting machine and other advanced processing equipment. At the same time, it also has the design and manufacturing capacity of pressure vessels, and can produce ships, petroleum, chemical, and other advanced processing equipment Metallurgy, printing and dyeing equipment. Our factory needs the existing industry (transformer manufacturing) supporting projects, such as transformer downstream industry: production, manufacturing furnace and other heating equipment. In this way, the new project can expand and expand the existing products, so that the old and new products match each other. The common problem to be solved in this project is to develop an intelligent controller and electrical appliance with monitoring and display connection function. Main functions: three section protection, thermal simulation, MCR, neutral line protection, ground fault protection, action characteristics, current unbalance protection, voltage protection, non frequency protection, over frequency protection, load monitoring function, phase sequence protection, reverse power protection, direction protection, display, fieldbus communication, etc.
