The QCD7000 distribution automation station terminal is a self-developed remote terminal for distribution automation systems based on the construction and development of smart grids. It meets the requirements of the "Standardized Design Scheme for 12 kV Primary and Secondary Integration Ring Main Unit (Box) and Distribution Automation Terminal Unit (DTU) (2021 Edition)". This device follows the modular plug-in design concept and adopts a high-speed and strong anti-interference field bus design. It is suitable for distribution network ring main units or switching stations, and can achieve information collection and control of multiple lines, as well as fault detection, positioning, isolation, and non fault area power supply recovery. It can effectively improve the reliability of the power supply system and shorten the fault handling time.
