Description

Technical Field

[0001] The invention relates to the field of temporary short-circuit grounding wire management, and in particular to a grounding wire positioning and identification device. Background Art

[0002] Temporary grounding wires are an important measure in the power system to ensure the safety of workers when voltage unexpectedly appears on equipment that has been powered off. The installation and removal of temporary grounding wires is an important operation in the power system.

[0003] As the management mode of dispatching, operation, inspection and maintenance changes from on-site manned substation to unmanned substation and the near-end information is fully transitioned to remote information management, the on-site safety measures are handed over from one to multiple work sites, resulting in the lack of real-time remote detection and tracking management of the installation and removal of grounding wires by existing technical means. Temporary grounding wires are often missed or removed. For example: State Grid Safety Accident Bulletin No. 2, February 28, 2009, the 35KV grounding wire power transmission accident at Hengshui Substation in Hebei Province was a typical power accident caused by the failure to count the number of grounding wire groups and carefully check the grounding wire numbers after removing all safety measures before power was supplied.
