Numerical control management system of earthing wire for 10KV distribution network overhead line

Abstract

A NC management system for earthing wire of 10KV distribution network overhead line is disclosed, characterized by comprising a server, a mobile terminal, an intelligent key, a ring lock and a groundwire, wherein the ground wire is provided with a ground terminal and an articulation terminal, the ring lock is used for locking the ground terminal and the articulation terminal of the ground wire together, and the ring lock is provided with an identity identification chip which is used for identifying the number of the ground wire; The smart key is used for reading the identification chip of thering lock and realizing the switching operation of the ring lock. The server communicates with the mobile terminal, and the mobile terminal electrically connects with the smart key. The intelligent key of the numerical control management system for the earthing wire of the 10KV distribution network overhead line can be unlocked only when the loop lock corresponding to the instruction of the mobile terminal is determined to be consistent after the identification chip is read, thereby avoiding the risk of misconnection of the earthing wire, thereby reducing the operation risk and improving thesafety.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a numerical control management system for grounding wires of overhead lines of a 10KV distribution network. Background technique [0002] In high-voltage lines, such as 10KV distribution network overhead lines, during power outage construction and maintenance of transmission lines, in order to ensure the personal safety of operators and prevent reverse transmission and induction of power transmission lines, both ends of the lines in the construction section need to be hooked The temporary grounding wire shall be removed after the task is completed, which has also become an indispensable safety measure to ensure the personal safety of construction workers. [0003] However, the transmission lines of the power system have the characteristics of long spans, many points and wide areas, and crossing mountains and mountains. When repairing these lines, it is often necessary to set ...

AI Technical Summary

Problems solved by technology

[0003] However, the transmission lines of the power system have the characteristics of long spans, many points and wide areas, and crossing mountains and mountains. When these lines are overhauled, it is often necessary to set up multiple sets of grounding wires, and the installation or removal of these grounding wires requires many people to work for a long time. Therefore, in actual work, there may be problems such as wrong connection and missing grounding wire, which seriously endanger the personal safety of construction and maintenance personnel.

In addition, when the construction and maintenance personnel in many places confirm the grounding state of the line, they need to manually report the situation to the dispatching center one by one, and wait for the dispatching center to issue an operation instruction manually. The process of confirming the grounding state of the line in this way takes a relatively long time. Long, making the maintenance time longer, and making the power outage longer
