The HDFK-12 Prefabricated Enclosed Ring Main Unit consists of an environmentally friendly gas-insulated ring main unit (including incoming and outgoing line units and a voltage transformer cabinet), a station terminal, an outer enclosure, and connecting cables. The eco-friendly gas ring main unit provides three-phase current signals (for protection and measurement) and zero-sequence current signals for each incoming and outgoing unit, as well as three-phase bus voltage and zero-sequence voltage signals. It also supplies secondary equipment power and switching operation power.
The DTU (Data Terminal Unit) integrates functions such as remote control, remote measurement, remote signaling (the "three remotes"), metering, phase-to-phase and ground fault handling, communication, and secondary power supply. The terminal supports interfaces for receiving data collected by line loss modules and communicates with the master station to upload electricity consumption data to the distribution automation master station. Additionally, it offers information access and forwarding for surrounding intelligent devices, local communication management, and regional control capabilities.
