Abstract

The invention belongs to the field of power supply and distribution system and discloses a ring network cabinet high-protection protection system and a method, which are provided with a DTU core unitfor centrally arranging and processing data of intervals, adjusting parameters of each intervals, issuing fixed values, and remotely controlling separation and merging. A power management unit connected with the DTU core unit and converting the PT alternating voltage to the voltage required by the electric device and the operating mechanism in the ring network cabinet. Through RS485 bus, the real-time data, waveform, switch quantity and line parameter information are uploaded to the feeder protection unit of DTU core unit. The signal hardware is distributed, and the bus is distributed to the DTU core unit, the power management unit and the fast connection unit of the feeder protection unit through the aviation plug cable. A centralized display connected to a DTU core unit and displaying analog measurement data for each interval. The invention adopts a fully sealed shell, which is composed of a lower shell and an upper cover, and is sealed with a silicone rubber strip between the lowershell and the upper cover.

Description

technical field [0001] The invention belongs to the field of power supply and distribution systems, and in particular relates to a high-protection protection system and method for a ring network cabinet. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: with the development of power distribution network, more and more methods of power supply in the ring network are used in the power distribution network. The department is widely used, so the requirements for the reliability and maintainability of the ring network cabinet are getting higher and higher, especially for the ring network cabinet to adapt to the harsh natural environment such as the high-humidity environment in the basement of urban buildings, the high-humidity salt spray environment in coastal areas, and the high-cold Regions, areas with strong wind and sand, etc. put forward higher and higher requirements. In order to adapt to the harsh installation e...
