State Grid standardized primary and secondary fusion ring net cage

In today's power system, the primary and secondary fusion ring net cage, as one of the core equipment in distribution sites, is leading the innovation and development of distribution technology with its unique advantages. This device not only integrates multiple functions of traditional distribution boxes, but also achieves seamless integration of primary and secondary functions through highly integrated design, providing a solid guarantee for the power supply of urban power grids, industrial production lines, and large building complexes.

Firstly, structurally speaking, the primary and secondary fusion ring net cage is centered around the primary and secondary fusion ring net cabinet, supplemented by key components such as high-voltage incoming cabinets and low-voltage incoming cabinets, to construct an efficient and stable power distribution system. Among them, the precision layout inside the primary and secondary fusion ring main unit integrates primary equipment such as high-voltage isolation switches and high-voltage load switches, as well as secondary equipment such as protection devices, control devices, and measurement devices. These components work together to complete the tasks of energy distribution, protection, monitoring, and measurement.

The biggest change brought about by this integrated design is that it breaks the limitation of separating the primary and secondary sides in traditional distribution equipment, and realizes intelligent management of the entire chain from power input to power output. Through highly integrated technological means, the primary and secondary fusion ring cage not only reduces the number of interfaces between devices and lowers the probability of failures, but also significantly improves the operational efficiency and reliability of the system.

In addition, with the continuous improvement of safety, energy conservation, and intelligence requirements in the power system, modern primary and secondary integrated ring cages have incorporated many advanced technologies. For example, it is equipped with telemetry, remote signaling, and remote control functions, allowing operation and maintenance personnel to remotely monitor the operating status of equipment, timely discover and handle potential problems; At the same time, it also has rich functions such as metering, phase to phase and ground fault handling, communication, and secondary power supply, providing comprehensive support for the stable operation of the power system.

It is particularly worth mentioning that the integrated design of the primary and secondary fusion ring net cage also brings convenience to construction and installation. In on-site construction, as most functions have been pre integrated into the equipment, the workload of on-site wiring and installation and debugging time have been greatly reduced, construction costs have been lowered, and work efficiency has been improved.
