Earth lead suspension dismounting management system

Abstract

An earth wire hanging, demolishing and management system is used for a power plant and a substation. The management is characterized in that a main control management platform is arranged in a command master-control room, and a secondary reexamination system is established for giving order of the demolishment of the earth wire, terminal operation and dismounting the earth wire to return the main control; a main control management program implements the earth wire hanging, demolishing and management system by a host simulating operation screen. The hard ware setting relates to that the earth wire combines with a tracker to be a signaling terminal; a troubleshooter carries out an order to the order target of an earth wire pile hanging tracker; the tracker keeps wired communication with the management system and displays position occupied; if errors are found when the demolished tracker carries out identifier reexamination at the main control platform, an audio alert works and full records are left in the main control program, therefore, the system realizes real-time communication with the dispatching of a higher authority and the local control. The management system constitutes two-level reexamination of the troubleshooter and a commander so as to ensure the correct hanging and demolishing of the earth wire and to avoid incorrect order manipulation accident; the system has the advantages of remarkable low cost and is a precautionary measure on work safety, which is easy and simple to implement in the present power sector.

Description

technical field [0001] The invention relates to the maintenance and management of electric facilities, and relates to a management system for hanging and removing grounding wires. Background technique [0002] The grounding wire is also called the grounding sealing wire. The grounding wire is mainly used in hydropower plants, thermal power plants, thermal power plants, and substations of various grades. In order to prevent the maintenance personnel from being harmed by the sudden incoming power or the induced voltage generated by the power failure equipment under maintenance and the residual charge of the maintenance equipment during power production and maintenance equipment, the three-phase power input to the maintenance equipment is short-circuited and grounded. The grounding wire is an important measure to protect the safety of maintenance personnel, and it is also an important step in the switching operation process. With the development of the economy, the electricity...

Problems solved by technology

Up to now, the power system lacks effective management in the grounding operation process, and still uses the warehouse to store marked ground wire terminals. Monitoring and management methods are relatively backward, and the probability of misoperation is relatively
