Application of ring main unit in power distribution system

This article explores the application of ring main units in urban distribution network construction and renovation in terms of development trends, types, advantages, and operational use. It proposes the basic viewpoint that SF6 ring main units should be used as much as possible in the current urban distribution network construction and renovation. With the continuous development of the economy and the increasing impact of electricity on people's lives, especially for urban areas with high load density, the reliability of power supply is particularly important. By establishing a distribution network mainly based on a ring network structure, the reliability of power supply can be effectively improved, the continuity of power supply can be ensured, and the impact of distribution equipment failures and maintenance power outages can be minimized. As an important equipment in the operation mode of the ring network, the application of the ring network cabinet in distribution network transformation is also becoming increasingly widespread. This article discusses the application of the ring network cabinet in urban distribution network transformation from the development trend of distribution network structure, the types, advantages, and operation and use of ring network cabinets.
