Description

A landscape ring network cabinet

technical field

The utility model relates to the field of electric equipment, in particular to a landscape type ring network cabinet.

Background technique

The ring network cabinet is a group of transmission and distribution electrical equipment installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. The main power supply line is formed into a closed ring through the electrical equipment, and the power supply is supplied to this ring Mains power supply, from the mains all the way through the high-voltage switch to distribute power to the outside. The advantage of this is that each power distribution branch can get power from its left side main line, and can get power from its right side main line. When the left main fails, it continues to receive power from the right main, and when the right main fails, it continues to receive power from the left main, so that although the main power supply is single, But from each power distribution branch, it can get benefits similar to dual-circuit power supply, thereby improving the reliability of power supply. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises.
