►Product Overview

The CWBC-02 Distribution Automation Feeder Terminal (Box-type FTU) is suitable for distribution networks with voltage levels of 10kV and above. It features monitoring and control functions for distribution network operation, as well as fault analysis and processing capabilities. This secondary terminal equipment for distribution automation can be used in conjunction with switches CKWZ(ZW28)-12/630-20 and CKWZ(ZW32)-12/630-20.

►Product Features

1. Real-time Monitoring and Data Acquisition:
The FTU collects key parameters such as feeder voltage, current, power factor, and temperature in real-time through built-in sensors. It supports power quality monitoring (e.g., harmonic analysis) and rapid identification of fault characteristics (e.g., zero sequence current and voltage fluctuations).

2. Rapid Fault Handling Capability:
Fault Location and Isolation: Upon detecting faults such as short circuits and grounding, the system can automatically disconnect the fault area and report to the main station. It supports remote or automatic execution of reclosing operations to minimize the scope of power outages.
Protection Functions: The system is equipped with instantaneous protection, overcurrent protection, low voltage protection, and more, in conjunction with the main station to achieve feeder automation.

3. Intelligent Communication and Integration:
It supports fieldbus protocols such as IEC61850 and MODBUS, with some models offering extended wireless communication capabilities (e.g., 4G, LoRa). It enables real-time interaction with the distribution main station and substations, facilitating remote control, parameter configuration, and software upgrades.
