Embodiment 1

[0030] figure 1 It is a flow chart of an optional operation method for a ground wire according to an embodiment of the present invention. Such as figure 1 As shown, the operation method of the ground wire in this embodiment includes:

[0031] S102: Receive a request message for requesting to take out the ground wire from the storage container in the locked state;

[0032] S104: Respond to the request message to obtain status information of the equipment to be grounded that is ready to be connected to the grounding wire;

[0033] S106: If the state information is used to indicate that the equipment to be grounded is in a charged state, return a response message for refusing to take out the grounding wire from the storage container, and instruct the storage container to remain locked;

[0034]S108: If the state information indicates that the device to be grounded is in an uncharged state, return a response message for allowing the ground wire to be taken out of the storage co...

Embodiment 2

[0037] In this embodiment, after receiving the request message for requesting to take out the grounding wire from the storage container in the locked state, and before responding to the request message to obtain the status information of the equipment to be grounded that is ready to be connected to the grounding wire, the method further includes: It is judged whether the ground wire is the Nth ground wire requested to be taken out in a group of ground wires indicated by the predetermined operation sequence.

[0038] Wherein, responding to the request message to obtain the state information of the equipment to be grounded that is ready to be connected to the grounding wire includes: when it is determined that the grounding wire is the Nth grounding wire that is requested to be taken out of the group of grounding wires indicated by the predetermined operation sequence, The status information of the equipment to be grounded that is ready to be connected to the grounding wire is ac...

Embodiment 3

[0047] In this embodiment, after receiving the request message for requesting to take out the grounding wire from the storage container in the locked state, respond to the request message and obtain whether the equipment to be grounded that is ready to be connected to the grounding wire is charged, and after obtaining the grounding wire When the device is not charged, before returning the response message for allowing the grounding wire to be taken out from the storage container, it is necessary to further determine whether the grounding wire is the Nth one in the group of grounding wires indicated by the predetermined operation sequence. Request to take out the ground wire; that is, to judge whether the predetermined ground wire operation sequence is correct. When it is determined that the ground wire is the Nth ground wire requested to be taken out in a group of ground wires indicated by the predetermined operation sequence, a response message for allowing the ground wire to ...

Abstract

The invention discloses an operation method and device of a grounding wire. The method comprises the following steps of receiving a request message for requesting to take out the grounding wire from a storage container in a locking state; responding to the request message to acquire state information on to-be-grounded equipment connected with the grounding wire; returning a response message for refusing to take out the grounding wire from the storage container and indicating that the storage container keeps the lock state if the state information is used for indicating that the to-be-grounded equipment is in a charged state; returning a response message for allowing to take out the grounding wire from the storage container and indicating that the storage container is switched from the locking state to an unlocking state if the state information is used for indicating that the to-be-grounded equipment is in an uncharged state. In the embodiment of the invention, the grounding wire is not allowed to be taken out from the storage container when the to-be-grounded equipment is in the charged state, so the technical problem of lower operation safety caused by error operation is solved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and device for operating a ground wire. Background technique [0002] The substation grounding wire is the lifeline to ensure the personal safety of the staff. The operation of installing and disassembling the grounding wire is very dangerous in electrical operations. Once an accident occurs, the impact will be great and the consequences will be serious. In the power system, the accidents of hooking the grounding wire with electricity or transmitting power with the grounding wire are not uncommon, and it is listed as one of the vicious misoperation accidents, and it is also the main source of man-made equipment accidents and personal casualties. It is an important task for the safe and reliable operation of the substation to ensure the correctness of the installation and disassembly of the grounding wire. [0003] In other words, currently, when grounding the eq...
