Description

Power grid overhauling and identifying device Technical Field The utility model relates to power grid overhaul, in particular to a power grid overhaul identification device. Background When the power grid needs to be overhauled, the power grid is powered off firstly and overhauling operation is carried out on the overhauling line, but residual voltage is still generated on the power grid after the power is powered off (the power grid after the power is powered off is equivalent to a capacitor), if a maintainer directly operates and is at risk of electric shock, the cable needs to be grounded after the power off is confirmed, and residual current in the cable is released to the ground, and the operation process needs to be in a grounded state all the time, so that the damage to the operator caused by accidental power on is prevented. The existing operation mode is that a grounding rod is hung on a cable, and the grounding rod is connected with the ground through a wire to realize the discharge to the ground. The disadvantage of this approach is that: 1. It is not possible to confirm whether the ground rod is in full contact with the cable and whether the current is effectively released. 2. The supervisory personnel can not confirm whether on-site operation personnel has carried out the earth treatment to the cable according to the requirement, or the supervisory problems such as earth failure in the maintenance process.
