Description

Ring main unit

Technical Field

The utility model relates to the technical field of ring main units, in particular to a ring main unit.

Background

The ring main unit is a group of electric equipment (high-voltage switch equipment) which is arranged in a metal or nonmetal insulating cabinet body or is made into an assembled spacing ring main power supply unit, and the core part of the ring main unit adopts a load switch and a fuse, and has the advantages of simple structure, small volume, low price, capability of improving power supply parameters and performance, power supply safety and the like. It is widely used in distribution stations of load centers such as urban residential communities, high-rise buildings, large public buildings, factory enterprises and the like, and box-type substations. The ring network refers to a ring-shaped power distribution network, namely, a power supply trunk line forms a closed ring shape, a power supply supplies power to the ring-shaped trunk line, and the power is distributed outwards from the trunk line through a high-voltage switch in a way of one path. This has the advantage that each distribution branch can be powered from both its left side mains and its right side mains. When the left main line fails, it continues to be supplied from the right main line, and when the right main line fails, it continues to be supplied from the left main line, so that, although the total power supply is single-path power supply, a benefit similar to double-path power supply is obtained from each distribution branch, thereby improving the reliability of power supply. The ring main unit is that each distribution branch is provided with a switch cabinet (outgoing switch cabinet), and the bus of the switch cabinet is a part of the annular trunk. That is, the ring trunk is formed by connecting the bus bars of each outlet cabinet. Each outlet cabinet is called a ring main unit. In practice, the meaning of "ring network" cannot be seen when a ring network cabinet is taken out alone.
