Embodiment 1

[0040] Embodiment 1, the solution to prevent live wires from being connected to the ground wire:

[0041] When the grounding wire needs to be connected, the power supply of the electrical equipment in the power failure has been disconnected and the switch is pulled to the isolation position. After the signal is transmitted to the electronic operation ticket system, a corresponding switching operation ticket is established. The upper computer of the grounding wire cabinet management receives the switch position signal of the electrical equipment that is powered off by the ECS control system and the switching operation ticket (marking the specific position of the grounding wire suspension), and performs five-proof logic verification on the electrical equipment corresponding to the electronic operation ticket. After passing the five-defense logic verification, the upper computer sends an unlock command to the grounding wire management cabinet to unlock the corresponding grounding ...

Embodiment 2

[0043] Embodiment 2, the scheme to prevent power transmission with ground wire:

[0044] When it is necessary to remove the grounding wire, create an operation ticket for removing the grounding wire, upload the operation ticket information to the grounding wire management host computer for five-proof logic, and issue an instruction to unlock the grounding wire after the verification is successful. The wire is suspended to the corresponding position, and the corresponding equipment is powered after the ground wire returns to its position. The whole operation work avoids the access of human operation and improves the safety factor of operation.

[0045] The specific process is as follows:

[0046] like figure 2 As shown, the temporary grounding line management machine reads the position information of the switch from the ECS; the electronic operation ticket system generates an operation ticket for the power-off state of the electrical equipment;

[0047] The information of the...

Abstract

The invention discloses a management system for a temporary ground wire, relates to the technical field of power grid management systems, and solves the technical problem that a ground wire managementmode in the prior art has potential safety hazards. The management system comprises an electrical monitoring management system and an electronic operation ticket system electrically connected with the electrical monitoring management system, and can make a switching operation ticket of an electrical equipment suspension ground wire and send the switching operation ticket. The system also comprises an upper computer of a ground wire management cabinet, wherein the upper computer can receive a division signal and a switching operation ticket and perform five-prevention logic judgment, and meetsthe following conditions: an unlocking instruction is sent to the ground wire cabinet through five-prevention logic judgment. The system also comprises a ground wire management cabinet which is usedfor receiving an unlocking instruction and unlocking the corresponding ground wire; and the state of the unlocked ground wire after being suspended again is transmitted to the upper computer through the ground wire management cabinet to be displayed. The system is used for achieving a wire connection management function, and avoids the potential safety hazards when a worker hangs and takes a wire.

Description

technical field [0001] The invention relates to the technical field of power grid systems, in particular to a management system for temporary grounding wires. Background technique [0002] The temporary grounding wire is an important tool in the power plant to ensure the safety of the staff when voltage unexpectedly appears on the equipment that has been powered off and the power distribution section. The main part that needs to be connected to the temporary grounding wire is the low-voltage side of the dry-type transformer. 380VMCC power distribution section. [0003] The practice of the prior art is: conventional power plants use a ledger system to manage the grounding wires. If they are used or removed, they are registered, and the grounding wires are registered and managed; the second is: the power plant uses an intelligent grounding wire cabinet for management. This grounding wire management cabinet has coded and identified temporary grounding wires, and carries out id...
