CWBC-02 column switch intelligent controller (box-type FTU) is suitable for distribution networks with voltage levels of 10kV and above. It has the functions of monitoring and controlling the operation of the distribution network, as well as the secondary terminal equipment of the distribution network automation, as well as the fault analysis and processing. Can be used with switches CKWZ (ZW28)-12/630-20, CKWZ (ZW32)-12/630-20.

Feature

Strong stability; the use of embedded real-time operating system fully guarantees the real-time, stability and portability of the system; 

Miniaturization; the system software adopts modular design and open architecture, and can load corresponding modules arbitrarily according to different equipment and applications, with good flexibility and tailorability; 

Rapid optimization; the main CPU adopts high-speed microprocessor DSP, which has a large information processing capacity and is easy to upgrade;

Remote maintenance; provide remote and local maintenance interfaces, so that operators can complete their maintenance locally or remotely such as the master station. It has the function of setting the action value locally or remotely; 

AC sampling; collect three-phase AC voltage and current to measure voltage, current, active power, reactive power, power factor and frequency;

DC sampling; collect DC quantity to realize DC voltage measurement;

Fault identification; collect and identify feeder fault current and transmit it to the sub-station or main station; have the function of on-site switching of fault action function; have the function of uploading the alarm of load exceeding the limit;

Historical data storage: It has the function of historical data storage, records telemetry and SOE data, and the data storage time of FTU feeder terminal is not less than 1 month.

High protection level; with high protection level, it can be installed indoors or outdoors, and the protection level reaches IP55;
