Abstract: The distribution terminal is an important component of the construction of distribution automation. It is mainly applied to 10 kV overhead lines, completing the operation detection and monitoring functions of distribution lines, achieving real-time monitoring of primary equipment such as switching stations, ring network cabinets, column switches, distribution transformers, capacitors, etc. on the 10 kV/20 kV distribution network. Through wired/wireless communication and other means, it uploads information, receives control commands, and achieves uninterrupted power supply, It provides the possibility for the further extension of intelligent power grid to the end distribution network.
