In a whole-box metering project for Hebei Provincial Power Company, the client required online monitoring of all parameters and intelligent main switch for the incoming line.
In Xiaochen Village, Dingzhou City, intelligent metering switches were used to achieve intelligent operation within the meter box, meeting the needs for meter malfunction analysis and replacement. Traditional switches were deeply integrated with high-precision measurement, communication, and control functions.
Enables online monitoring of all parameters at the distribution terminal, ensuring data accuracy and real-time performance.
The intelligent metering switch, in addition to the short-circuit and overload protection functions of ordinary switches, adds overvoltage, undervoltage, and phase loss protection, terminal temperature measurement, and high-precision measurement functions.
The product features multiple communication methods, supporting communication with concentrators and intelligent fusion terminals to upload data to the main station, effectively supporting line loss analysis and electricity meter inaccuracy analysis.
The metering unit is hot-swappable, supporting uninterrupted repair and replacement.
The product supports the metering needs of Hebei’s metering boxes, fully aligning with the “State Grid Three-Year Action Plan” guidelines; it has received unanimous praise from State Grid headquarters and Hebei Company.
