Grounding wire device for power grid maintenance and grounding condition monitoring method thereof

Abstract

The invention discloses a grounding wire device for power grid maintenance and a grounding condition monitoring method thereof, the grounding wire device comprises an electricity testing device, a resistance monitoring device, a position monitoring device, a power transmission line hook, a grounding wire, a cable pressing piece and an operating rod, and the hanging of the grounding wire device and the connection of the grounding wire and a power transmission line are realized through the power transmission line hook, the cable pressing piece and the operating rod; the grounding resistance is monitored in real time through the resistance monitoring equipment and is compared with the grounding resistance value under the normal grounding condition, so that whether the grounding wire is effectively grounded or not is judged; meanwhile, the position of a grounding wire hanging point is monitored in real time through position monitoring equipment so as to judge whether the hanging point is located in an effective grounding range or not; meanwhile, before grounding operation is carried out, the circuit is overhauled through an electricity testing device for electricity testing, and whether the circuit is still electrified or not is judged; the real-time monitoring of the grounding condition of the grounding wire is comprehensively realized, the electric shock probability of an operator is reduced, and the safety of power grid maintenance work is improved.

Description

technical field [0001] The invention relates to the technical field of on-site operation safety of electric grass-roots teams, in particular to a grounding wire device used for power grid maintenance and a grounding condition monitoring method thereof. Background technique [0002] When the power grid system is overhauled, it is necessary to hook up the grounding wire on the transmission line after the switch is turned off to prevent the transmission line from being electrified due to false closing and other situations, so that the maintenance operator may be in danger of electric shock when working. At present, during the daily maintenance of power grid lines, operators usually use the naked eye to judge the safety and reliability of the connection of the grounding wire. This method is subject to greater subjectivity and is prone to misjudgment , causing the operator to carry out maintenance under the condition of effective grounding; at the same time, the grounding conditi...

[0002] When the power grid system is overhauled, it is necessary to hook up the grounding wire on the transmission line after the switch is turned off to prevent the transmission line from being electrified due to false closing and other situations, so that the maintenance operator may be in danger of electric shock when working

At present, during the daily maintenance of power grid lines, operators usually use the naked eye to judge the safety and reliability of the connection of the grounding wire. This method is subject to greater subjectivity and is prone to misjudgment , causing the operator to carry out maintenance under the condition of effective grounding; at the same time, the grounding condition of the grounding wire is only judged before the maintenance, and the grounding ability of the grounding wire cannot be lost in time during the maintenance process, thus causing the operator to get an electric shock Danger
