The intelligent ring network cabinet based on the chip system includes two parts: the interval unit and the common unit.
To cope with the high reliability of the complete set of ring network cabinets, we adopted the principle of redesign, adopted the principle of distributed station terminals, and re-studied the distributed intelligent distribution terminals based on the idea of chip system.
The ring network cabinet adopts distributed DTU, which is different from the traditional centralized DTU, the distributed DTU is composed of a common unit and several bay units.
At present, SF6 ring network cabinets are mainly used in China, and solid insulation ring network cabinets have been gradually used. At present, there are many problems in ring network cabinets, such as low level of automation and informatization, low stability of equipment operation, and poor environment for equipment replacement and maintenance.
At present, there are many problems in ring network cabinets, such as low level of automation and informatization, low stability of equipment operation, and poor environment for equipment replacement and maintenance. Distribution Terminal Unit (DTU) is one of the most important units in the distribution ring network cabinet.
Relevant research has proposed a holographic perception intelligent fusion ring network cabinet, which has holographic perception and edge computing capabilities, and can meet the plug and play, topology automatic analysis and upload functions of different terminals [12, 13, 14].
