Description

Technical Field

[0001] The utility model belongs to the field of intelligent control of power distribution stations, in particular to an intelligent monitoring cabinet of a power distribution station room. Background Art

[0002] Power distribution is the link in the power system that is directly connected to the user and distributes electric energy to the user. The power distribution system consists of a distribution substation, a high-voltage distribution line, a distribution transformer, a low-voltage distribution line, and corresponding control and protection equipment. The distribution network is an important part of the smart grid. With the increase of working hours and changes in environmental conditions, it is inevitable to encounter extreme weather such as lightning strikes and icing, which will cause distribution station failures. At present, the status monitoring of distribution stations mainly adopts manual inspections. The efficiency and quality of the inspections are mainly determined by the work experience and attitude of the inspectors themselves, and the regular inspections are adopted, resulting in some equipment hidden dangers that cannot be discovered in time, causing safety accidents. CN212343427U provides a distribution station intelligent status monitoring system, which uses terminal sensors to collect data in the distribution network, and uses edge computing devices to fuse the collected data, which can effectively reduce bandwidth, enable the real-time storage of data to be widely expanded, and effectively reduce network load.
