Transformer substation grounding wire monitoring device and monitoring method thereof

Abstract

The invention relates to a transformer substation grounding wire monitoring device which comprises a grounding wire cabinet with a plurality of independent drawers. The monitoring device is characterized in that each drawer is internally provided with a laminate plate, and an elastic piece is arranged below the laminate plate; a sensor for sensing the deformation quantity of the elastic piece and sending switching signals is arranged below the laminate plate of each drawer; the monitoring device also comprises a collector, a concentrator, a display screen and a server, wherein the collector is arranged in the grounding wire cabinet, electrically connected with the sensors and used for collecting and storing switching signals sent by each sensor; the concentrator is electrically connected with the collector and used for realizing the information transmission with the collector; the display screen is electrically connected with the concentrator and used for realizing the information transmission with the concentrator; and the server is provided with a database and background management software and connected with a concentrator network through an electric power local area network. Compared with the prior art, the invention has the advantages of simple structure of the whole set of equipment, low cost and higher promotional value and can truly realize the informationization management, improve the safe production efficiency and effectively stop the occurrence of power transmission accidents caused by switching on with grounding wires.

Description

technical field [0001] The invention relates to a management system for substation grounding wires, in particular to a management device for real-time monitoring of the use status of the grounding wires and a monitoring method using the device. Background technique [0002] In the production work of electric industry, the grounding wire is the most direct protection measure to ensure that the workers are protected from electric shock. The operation of installing and disassembling the grounding wire is a relatively dangerous operation in electrical operations. In the power system, the accidents of connecting the grounding wire with electricity or power transmission with the grounding wire are the main causes of personal casualties and man-made equipment accidents. Therefore, ensure that the installation The correctness of removing the ground wire is an important task for the safe and reliable operation of the substation. [0003] Generally, the power system is clearly stipul...

Problems solved by technology

This patent realizes the automatic real-time monitoring and management of the substation ground wire information through the digitization of the substation ground wire information. RFID tags must also be equipped with a wireless communication controller with a passive RFID label reader. The establishment of such a radio frequency communication system requires a series of supporting equipment involving radio frequency transmitters, readers, encoders and antennas. The cost of equipment transformation and configuration is high; moreover, since the country has special regulations on wireless radio frequency and transmission power, each frequency has different applications, which makes the working frequency of radio frequency can only be selected within a fixed range , is greatly restricted by the environment and technical parameters, and is not easy to maintain
