An intelligent management and control system for grounding wires in substations

Abstract

The invention provides a ground lead intelligent control system for a transformer substation. The ground lead intelligent control system comprises a ground lead intelligent control unit, a ground lead lock and a ground electromagnetic lock, and a ground lead is only taken out or put back when the ground lead lock opens the ground lead through a related authorized electronic key to take out or return a digital lock. The ground lead can be hung when the ground electromagnetic lock meets the condition of hanging the ground lead and the electromagnetic lock is authorized to be unlocked, and after a special pile head of the ground lead is inserted into an outer shell of the ground electromagnetic lock, the in-place condition of the pile head of the ground lead and the number of the ground lead are detected through a detection hole. The system monitors the process from storage management to use of the ground lead, the whole operation process of the temporary ground lead is guaranteed to meet the operation procedure and the management standard of safety regulation, the ground electromagnetic lock is reasonable in designed structure, and the resource cost is reduced.

Description

technical field [0001] The invention belongs to the application technical field of electric power installation and maintenance auxiliary devices, and in particular relates to an intelligent management and control system for grounding wires used in substations Background technique [0002] In the production work of the electric industry, the grounding wire is the most direct protection measure to ensure that the staff are not injured by electric shock. Therefore, when the staff work on the power outage equipment, the main safety measure to prevent electric shock is to install the grounding wire. Installing the grounding wire includes closing the grounding isolation switch (knife switch) and hanging the grounding wire (portable grounding wire, referred to as the grounding wire). Its function is to release the residual charge on the power failure equipment, and limit the rise of the equipment to the ground potential when a sudden power comes on, so as to protect the staff from ...

Problems solved by technology

As a lifeline to protect the personal safety of staff, any improper operation, use and management of it may lead to safety production accidents

[0004] In actual work, due to the frequent use and simple operation of the grounding wire, it is easy to paralyze people's thinking

At present, in addition to some basic requirements for the use of grounding wires in most power companies, the specific use and management of grounding wires are not standardized enough, and there is no more practical and effective method for the storage, use, and maintenance of grounding wires. Effective management and control of each link such as assembly and disassembly, the management of the grounding wire is more dependent on the user's own safety awareness and self-consciousness, lack of effective technical means or measures to support the management

At present, there is a problem of random use of grounding wires without records, and the access and use of substation grounding wires cannot be monitored.

[0005] The grounding electromagnetic lock is mainly an electrical grounding locking device developed for electric automation substations as an electrical locking device. It locks the grounding rod during maintenance, but the existing grounding electromagnetic lock does not have the functions of identifying and controlling the grounding wire, which may cause errors. Unplugging and inserting the ground rod by mistake
