Management device for hanging grounding wire in transformer substation based on Internet of Things

Abstract

The invention discloses a transformer substation grounding wire hanging management device based on the Internet of Things and belongs to the field of safety. A high-frequency RFID positioning reader-writer is correspondingly arranged at each grounding wire terminal; a grounding wire RFID tag is arranged on each grounding wire; an RFID concentrator is arranged on the site of the grounding point of the transformer substation; a router with an Internet of Things card is arranged on the site of a substation grounding point; a server is arranged in the transformer substation; a display terminal is arranged in a transformer substation central control room; when the grounding wire is connected to a grounding point, the high-frequency RFID positioning reader-writer generates high-frequency signals and sends the signals to the RFID concentrators, and the high-frequency signals of the RFID concentrators are gathered through the router with the Internet of Things card; the collected high-frequency signals are sent to a server; the display terminal in the central control room can display which grounding point is connected with the grounding wire and which grounding point is idle. The method can be widely used in the field of substation grounding wire management.

Description

technical field [0001] The invention belongs to the field of emergency safety devices, in particular to a management device for substation grounding wires. Background technique [0002] Grounding wire is a commonly used inspection and maintenance tool in the power system. It has the characteristics of large quantity, simple operation, high demand for use, scattered operations, and wide distribution. [0003] The existing regional power supply centralized control center station (referred to as the central station) generally governs about 300 substations of various voltage levels. The number of grounding wires is huge, the locations are relatively scattered, and the installation and removal period of the grounding wires is long. The main function of the grounding wire is to protect the personal safety of the maintenance personnel and prevent the injury to the human body caused by a sudden call. [0004] For the large number and frequently used grounding wires, the domestic po...

AI Technical Summary

Problems solved by technology

[0008] In fact, in the major safety accidents of power grids at home and abroad, vicious misoperation accidents such as live connection to the ground wire or power transmission with the ground wire still occur from time to time. Program operation to avoid misinstallation and missing removal of the ground wire, but it cannot solve the problem of safe removal of the temporary ground wire in the substation. And other working links cannot be monitored and determined in real time, so that there are security loopholes in the existing anti-mistake system, and the closing behavior with the ground wire cannot be discovered and stopped in time
