Brief Analysis of the Solutions for Step-by-step Switching of Medium-voltage Loads at the Data Center
According to the control requirements for step-by-step load switching device at the data center,several widely used solutions for step-by-step load switching are compared and analyzed,including step-by-step switching device for special loads,10 kV dual-power changeover switch controller with step-by-step load switching function,PLC controller independently built and programmed with discrete components and automatic control of digital communication based on IEC 61850 optical fiber ring network GOOSE transmission technology,and suggestions are proposed for selection.
