Demands of Metallurgy Industry
Steel industry is one typical example of metallurgy industry, and it is a high energy consumption industry. For a large-sized steel factory, the energy cost is about 30% of the total production cost, and the electricity takes up more than 10 percent of the total production cost. One key factor for these factories is to cut down energy consumption and make better use of electricity.
Sfere series and PD19 series power quality monitors are suitable to measure and analyze electric energy to well satisfy the requirements of energy management system and analysis system. Aside from these, it also has other functions, such as multi-rate electricity calculation, active and reactive power metering, etc.
WDH-31 series motor protection controller is applicable for the steel industry, and it can supply perfect protection for different motors, including overcurrent protection, overheat protection, trip setting function, etc. If the current is not over 250A, it can be connected to the main circuit directly, otherwise a mutual inductor is needed. Additionally, this product is equipped with many communication ports, supporting Modbus-RTU protocol and Profibus-DP protocol.
Case: Motor Protection System for Chongqing Iron and Steel Co., Ltd
WDH-31 motor protection controller is able to carry out all the protection operations and parameter measurements on site, and the historical data for every parameter can be queried. It can automatically create reports for energy consumption and alarm message, which brings great convenience to print daily, monthly or annual energy consumption report.
