Application of Ring Main Unit in Distribution System

The application of ring main unit (RMU) in urban distribution network construction and renovation is discussed in terms of development trends, types, advantages, and operational use of RMU. The basic viewpoint is proposed that SF6 RMU 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 the 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 of the ring network, the application of the ring network cabinet in distribution network transformation is also becoming more and more widespread. This article discusses the application of the ring network cabinet in urban distribution network transformation from the development trend of distribution network structure, types, advantages, and operation use of the ring network cabinet.
