Problems solved by technology
According to the applicant's understanding, most electric power companies currently have some basic requirements for the use of grounding wires in the system, but the specific use and management of grounding wires are not standardized enough, and there are many problems. The traditional manual reporting method is likely to lead to temporary grounding Electrical accidents such as misconnection, misconnection, missed connection, and missed disconnection of the wires have occurred, making the grounding wire that should have a protective effect become a major hidden danger of misoperation
Once an accident occurs, the consequences will be serious

Embodiment
[0021] The substation ground wire real-time monitoring and management method provided by this embodiment, such as figure 1 As shown, wherein, the substation has an access control system 5, and the access control system 5 includes a card reader 11, a card distributed to the operator, an access controller 10 and an electric control lock 12. When working, the card reading signal of the card reader 11 outputs The terminal is connected to the card reading signal input terminal of the access controller 10, and the control signal output terminal of the access controller 10 is connected to the controlled terminal of the electric control lock 12, so as to control the opening and closing of the lock head. In addition, the door 13 is equipped with a signal output terminal The door status sensor of the access controller 10 status signal input end. Access control controller 10 is purchased from NARI company's model NSV-818 controller, and electric control lock 12 is purchased from NARI com...

The invention relates to a taking and returning management method of a ground wire in a transformer substation, belonging to the technical field of electrical power system security. The method comprises the steps of setting permission, judging access permission, judging ground wire permission, judging ground wire specification, etc. The invention provides a transformer substation ground wire real-time monitoring and management method which is based on an independent 'five-prevention' system; after the method is used, the whole processes such as transformer substation ground wire registration, in-place state, authorization, using position, and returning can be monitored and managed by an intelligent access control system, internet of things, a network technique, computer management software, embedded data acquisition and the like.
Description
technical field [0001] The invention relates to a management method for grounding wires in substations, belonging to the technical field of power system security. Background technique [0002] The substation grounding wire is a necessary safety tool for electrical circuit or equipment power outage maintenance work, and is the lifeline to ensure the personal safety of operating personnel. According to the applicant's understanding, most electric power companies currently have some basic requirements for the use of grounding wires in the system, but the specific use and management of grounding wires are not standardized enough, and there are many problems. The traditional manual reporting method is likely to lead to temporary grounding Electric accidents such as misconnection, mistaken disconnection, missed connection, and missed disconnection of wires have occurred, making the grounding wire that should play a protective role become a major hidden danger of misoperation. Onc...
